Core Concepts of VMware Horizon 7.7 for the 2V0-51.19 Exam

Virtual Desktop Infrastructure, commonly known as VDI, is a technology that hosts desktop operating systems on a centralized server in a data center. This paradigm shifts the desktop environment from a physical device on a user's desk to a virtual machine (VM) managed by the IT department. For professionals preparing for the 2V0-51.19 Exam, a firm grasp of VDI fundamentals is the starting point. VDI provides numerous benefits, including centralized management, enhanced security, improved data control, and greater flexibility for end-users to access their desktops from any device, anywhere.

The core principle of VDI is the separation of the user's desktop environment from the physical endpoint device. Users connect to their dedicated virtual desktops using a remote display protocol, which transmits the desktop's user interface over a network. This means the actual processing occurs on the powerful servers in the data center, not on the end-user's device. This makes it possible to use low-cost thin clients or even personal devices to access a full-featured Windows desktop. The 2V0-51.19 Exam is designed to validate your ability to deploy and manage such an infrastructure using VMware Horizon.

Understanding the VMware Horizon Architecture

The architecture of VMware Horizon 7.7 is a critical area of study for the 2V0-51.19 Exam. Horizon is not a single product but a suite of components that work together to deliver virtual desktops and applications. At the heart of the architecture is the Horizon Connection Server. This server acts as the broker for client connections, authenticating users against Active Directory and then directing them to their assigned virtual desktop or application. It is the central management point for the entire Horizon environment.

Another key component is the vCenter Server, which is VMware's platform for managing the underlying vSphere infrastructure. Horizon integrates deeply with vCenter Server to provision and manage the lifecycle of the virtual desktop VMs. The virtual desktops themselves run on ESXi hosts, which are the hypervisors that provide the virtualization layer. For external access, the Unified Access Gateway (UAG) provides a secure entry point into the virtual environment from the internet, without requiring a traditional VPN connection.

Finally, the end-user interacts with their virtual desktop through the Horizon Client, which is available for a wide range of devices, including Windows, macOS, Linux, iOS, and Android. The client communicates with the Connection Server and establishes a session using a display protocol like Blast Extreme or PCoIP. Understanding the role and interaction of each of these components is fundamental to passing the 2V0-51.19 Exam and successfully managing a Horizon environment.

The Role of the Horizon Connection Server

The Horizon Connection Server is the primary component of a Horizon deployment and is a major focus of the 2V0-51.19 Exam. It serves as the central broker, managing the authentication and connection process for all incoming user requests. When a user launches their Horizon Client, their first point of contact is the Connection Server. The server authenticates the user's credentials against Microsoft Active Directory and then determines which desktops or applications the user is entitled to access based on their group memberships.

In addition to brokering connections, the Connection Server is the administrative hub for the entire Horizon environment. Administrators use the Horizon Administrator console, a web-based interface hosted on the Connection Server, to perform all management tasks. This includes creating and managing desktop pools, entitling users to resources, configuring global policies, and monitoring the health of the system. For high availability, multiple Connection Servers can be deployed in a replicated group, ensuring that the brokering service remains online even if one server fails.

The Connection Server also integrates with other components of the Horizon suite. For example, it communicates with the vCenter Server to manage the virtual desktop VMs and with App Volumes Managers to handle the delivery of applications. A deep understanding of the Connection Server's roles, its installation, and its configuration is a non-negotiable requirement for anyone preparing for the 2V0-51.19 Exam.

Understanding Display Protocols: Blast Extreme and PCoIP

The user experience in a VDI environment is heavily dependent on the performance of the remote display protocol. The 2V0-51.19 Exam will expect you to be knowledgeable about the protocols supported by Horizon 7.7, primarily Blast Extreme and PCoIP. These protocols are responsible for compressing, encrypting, and transmitting the desktop's display information to the end-user's client device, and for sending keyboard and mouse inputs back to the virtual desktop.

Blast Extreme is VMware's purpose-built display protocol, optimized for the mobile cloud. It is based on the H.264 video codec, which is widely supported in hardware, allowing for lower CPU consumption on both the client and the server. Blast Extreme is highly adaptive to different network conditions and can provide an excellent user experience over both LAN and WAN connections. It supports a wide range of client devices and is generally the recommended protocol for most use cases in modern Horizon environments.

PCoIP (PC over IP) is another mature and robust protocol that has been a part of Horizon for many years. It is known for its ability to deliver a high-fidelity, lossless desktop experience, making it suitable for graphically intensive workloads. While Blast Extreme has become the preferred protocol for its efficiency and flexibility, PCoIP remains a viable option. For the 2V0-51.19 Exam, you should understand the key features, benefits, and typical use cases for both protocols, as well as how to configure them using policies.

Core vSphere Components for Horizon

A successful Horizon deployment relies on a solid underlying vSphere infrastructure. The 2V0-51.19 Exam requires you to understand the role of the core vSphere components. The most important of these is the ESXi host. ESXi is the bare-metal hypervisor that you install on your physical servers. It is responsible for creating and running the virtual machines that will serve as the virtual desktops for your users. The performance and scalability of your VDI environment are directly tied to the power and resources of your ESXi hosts.

The vCenter Server is the centralized management platform for your ESXi hosts and virtual machines. From the vCenter Server, you can create virtual machine templates, manage host clusters, configure storage and networking, and monitor the performance of the entire virtual infrastructure. Horizon integrates directly with vCenter Server to automate the process of creating, managing, and deleting virtual desktops. You cannot have a Horizon environment without a vCenter Server.

Storage and networking are also critical vSphere components. For storage, you will need a shared datastore, such as a SAN or NAS, that is accessible to all the ESXi hosts in your cluster. This allows for features like vMotion and High Availability. For networking, you will need to configure virtual switches (vSwitches) to provide network connectivity to your virtual desktops. A proper design of your vSphere environment is a prerequisite for a stable and performant Horizon deployment, and is a key area of knowledge for the 2V0-51.19 Exam.

Introduction to Desktop Pool Concepts

In Horizon, virtual desktops are managed in groups called desktop pools. A desktop pool is a collection of virtual desktops that share a common configuration. Understanding the different types of desktop pools is a fundamental topic for the 2V0-51.19 Exam. The main categories are automated pools and manual pools. An automated pool is one where Horizon automatically creates and manages the virtual machines based on a template or golden image that you provide.

Within automated pools, there are different provisioning methods. You can create full clones, which are independent copies of the golden image, or you can use space-efficient technologies like linked clones or instant clones. A manual pool is a collection of existing virtual machines that you want to manage through Horizon. This is useful if you have existing VMs or physical machines that you want to make available to users.

You also have the choice between dedicated and floating assignment for your pools. In a dedicated assignment pool, each user is assigned a specific virtual desktop that they get every time they log in. This allows for user-installed applications and persistent settings. In a floating assignment pool, users are given a random desktop from the pool each time they log in. When they log out, the desktop is typically refreshed back to its original state. The choice of pool type has significant implications for management, storage, and user experience.

Understanding User Profiles and Personas

In a non-persistent VDI environment, where users get a fresh desktop at each login, managing the user's personality and data is a critical challenge. The 2V0-51.19 Exam will test your knowledge of the solutions available for this in Horizon 7.7. A user profile contains all the user-specific settings, such as their desktop background, application settings, and documents. In a physical desktop world, this data is stored locally on the C: drive. In a floating VDI environment, this data would be lost when the desktop is refreshed.

To solve this, you need a profile management solution. VMware offers the User Environment Manager (UEM) as part of the Horizon suite. UEM is a powerful tool that allows you to capture user settings for the operating system and applications and save them to a network share. When a user logs into a new desktop, UEM applies these saved settings, providing the user with a consistent and personalized experience, regardless of which desktop they are assigned.

UEM goes beyond simple profile roaming. It allows for granular control over the user environment. You can manage application settings, configure environment variables, map printers and drives, and even create application shortcuts based on user context, such as their location or the type of client device they are using. Understanding the capabilities of UEM and how it helps to solve the profile management challenge is a key part of the knowledge required for the 2V0-51.19 Exam.

Preparing for a Horizon Installation

A successful VMware Horizon deployment begins with meticulous planning and preparation, a process that is a core competency tested in the 2V0-51.19 Exam. Before you even begin the installation, you must ensure that your underlying infrastructure is ready. This includes having a properly configured and licensed vSphere environment, with ESXi hosts and a vCenter Server. You also need to have Microsoft Active Directory set up, as Horizon relies on it for user authentication and group management.

Network infrastructure is another critical prerequisite. You will need to have your DNS servers configured correctly, with both forward and reverse lookup zones. It is essential that all the Horizon components can resolve each other's hostnames. You will also need to have a number of static IP addresses available for the various Horizon servers. Additionally, you need to prepare the necessary service accounts in Active Directory with the appropriate permissions for Horizon to interact with vCenter Server and perform other administrative tasks.

Finally, you need to have a database server prepared for storing Horizon events and, if you are using linked clones, for the View Composer database. Microsoft SQL Server is a common choice for this. Having all these prerequisites in place and documented before you start will make the installation process much smoother and is a key aspect of the professional approach expected of candidates for the 2V0-51.19 Exam.

Installing the Horizon Connection Server

The installation of the Horizon Connection Server is the first major step in building a Horizon environment and is a task you must be intimately familiar with for the 2V0-51.19 Exam. The installation is performed by running an executable installer on a dedicated Windows Server machine. The installer will guide you through a wizard where you will make several important configuration choices.

During the installation, you will choose the type of Connection Server you are installing. The first server in a new environment is always a Standard Server. If you are adding a second server for high availability, you would choose to install it as a Replica Server. The installer will also prompt you to set a data recovery password, which is a critical piece of information that you will need if you ever have to restore the Connection Server's configuration from a backup.

The installer will also configure the necessary firewall rules on the Windows Server to allow for communication on the various ports that Horizon uses. Once the installation is complete, you can access the Horizon Administrator console by navigating to the server's address in a web browser. A clean and correct installation of the Connection Server is the foundation of your entire VDI deployment, and the 2V0-51.19 Exam will test your knowledge of the steps and options involved in this process.

Configuring the Horizon Event Database

After installing the Horizon Connection Server, one of the first configuration tasks you should perform is to set up the Event Database. This is an important step that is covered in the 2V0-51.19 Exam. The Event Database is a SQL database where the Connection Server stores information about system events, user sessions, and administrative actions. This data is invaluable for monitoring, troubleshooting, and auditing your Horizon environment.

To configure the Event Database, you log in to the Horizon Administrator console and navigate to the Event Configuration section. Here, you will provide the connection details for your database server, including the server name, the database name, and the credentials for the user account that Horizon will use to access the database. You can also configure how long you want to retain event data in the database.

Without a properly configured Event Database, you will have very limited visibility into the historical activity in your environment. The Horizon Administrator console will not be able to display detailed logs or generate reports. Therefore, setting this up is a critical best practice. For the 2V0-51.19 Exam, you should be comfortable with the procedure for configuring the Event Database and understand the importance of the data it contains.

Installing and Configuring View Composer

If you plan to use linked-clone desktops, you will need to install and configure View Composer. This component is a key topic for the 2V0-51.19 Exam as it relates to a specific and widely used desktop provisioning technology. View Composer is a service that works with vCenter Server to create and manage linked clones. A linked clone is a virtual machine that shares a virtual disk with its parent or golden image, which results in significant storage savings.

View Composer is installed on its own Windows Server machine (or it can be co-located with vCenter Server, though this is less common). The installation process is wizard-driven. A key step during the installation is to create an ODBC database connection to a SQL database. Composer uses this database to keep track of the relationships between the linked clones and their parent images.

Once Composer is installed, you need to add it to your Horizon configuration. This is done in the Horizon Administrator console, where you will provide the address of the Composer server and the credentials for it to communicate with vCenter Server. You also need to add the Active Directory domain that will be used for the QuickPrep process, which is Composer's method for customizing the linked-clone desktops after they are created. A solid understanding of Composer's role and its setup is essential.

Integrating with vCenter Server and Active Directory

The deep integration with vCenter Server and Active Directory is what makes Horizon a powerful VDI solution. The configuration of this integration is a core task for an administrator and a major subject in the 2V0-51.19 Exam. To integrate with vCenter Server, you add its details in the Horizon Administrator console. You will provide the vCenter Server's address and the credentials for a service account that has the necessary permissions to perform VM operations.

This integration allows the Connection Server to communicate with vCenter to automate the entire lifecycle of your virtual desktops. When you create a desktop pool, Horizon will call the vCenter API to clone the golden image, create the new VMs, and add them to the inventory. It will also manage power operations, such as powering on desktops when users request them.

The integration with Active Directory is just as critical. You will register your Active Directory domains with Horizon. This allows the Connection Server to authenticate users and to query for groups when you are entitling users to desktop pools. Horizon also relies on Active Directory for the computer accounts of the virtual desktops. Understanding how to configure these integrations and troubleshoot any issues with them is a fundamental skill for the 2V0-51.19 Exam.

Configuring Role-Based Administration

In any enterprise environment, it is important to follow the principle of least privilege when granting administrative access. The 2V0-51.19 Exam will expect you to know how to implement this using Horizon's role-based administration feature. Horizon comes with a set of pre-defined administrator roles, such as Administrators, Inventory Administrators, and Help Desk Administrators. Each of these roles has a specific set of permissions.

For example, the full Administrators role has permission to do everything in the environment. The Inventory Administrators role can manage desktop pools but cannot change global settings. The Help Desk Administrators role has limited permissions, primarily to view user sessions and perform basic troubleshooting tasks like restarting a user's desktop. You can assign these roles to Active Directory users or groups to delegate administrative responsibilities.

In addition to the pre-defined roles, you can also create your own custom roles with a granular set of permissions. This allows you to tailor the administrative access to the specific needs of your organization. For example, you could create a role for your application packaging team that only allows them to manage application pools. The ability to properly configure role-based administration is a key skill for maintaining a secure and well-managed Horizon environment.

Setting up the Unified Access Gateway (UAG)

For users who need to access their virtual desktops from outside the corporate network, you need a secure way to provide that access. The VMware Unified Access Gateway (UAG) is the recommended solution for this, and its configuration is a key topic for the 2V0-51.19 Exam. The UAG is a hardened Linux virtual appliance that you deploy in a DMZ or demilitarized zone in your network. It acts as a secure proxy, forwarding the remote desktop traffic from the internet to the Horizon components on your internal network.

The deployment of the UAG is typically done by importing an OVA file into your vSphere environment. During the deployment wizard, you will configure the network settings for the appliance, including the IP addresses for its external and internal network interfaces. After the appliance is deployed, you perform the final configuration through a web-based administrative interface.

In the UAG's admin interface, you will configure the "edge service" for Horizon. This involves providing the address of your internal Horizon Connection Server. You will also need to upload the SSL certificate for the external URL that users will connect to. The UAG provides a much more secure and feature-rich solution than a traditional VPN, and understanding how to deploy and configure it is a critical skill for any modern Horizon deployment.

Creating and Configuring Automated Desktop Pools

The core of any VDI deployment is the creation of desktop pools, and this is a primary focus of the 2V0-51.19 Exam. An automated desktop pool allows Horizon to provision and manage a collection of virtual desktops from a single golden image. When you create an automated pool using the wizard in the Horizon Administrator console, you will make a series of important decisions that define the characteristics of the desktops in that pool.

First, you will choose the user assignment type: dedicated or floating. Dedicated assignment gives each user a specific desktop that they use every time, allowing for persistence. Floating assignment provides users with a random desktop from the pool, which is typically refreshed or deleted on logout, ensuring a clean state for the next user. This choice has major implications for user experience and management.

Next, you will select the provisioning technology. For automated pools, the main choices are full clones, linked clones (if you have Composer), or instant clones. Full clones are complete, independent copies. Linked and instant clones are space-efficient clones that share a base disk with the golden image. The 2V0-51.19 Exam will expect you to understand the benefits and requirements of each of these technologies and to know how to configure the various settings in the pool creation wizard.

Understanding Full, Linked, and Instant Clones

A deep understanding of the different cloning technologies available in Horizon 7.7 is essential for the 2V0-51.19 Exam. Full clones are the simplest to understand. They are an exact, full-sized copy of the golden image VM. This means they are completely independent, but they also consume a large amount of storage. Managing and patching full clones can be cumbersome as each one needs to be updated individually.

Linked clones, which require View Composer, are much more storage-efficient. A linked clone is created from a snapshot of the parent VM. It has its own unique "delta" disk that stores only the changes made from the parent. This can result in storage savings of up to 80% compared to full clones. Patching is also much easier; you simply update the parent image and then "recompose" the pool, which updates all the linked clones to the new version.

Instant clones are the most advanced cloning technology. They use VMware's vmFork technology to create new desktops almost instantaneously. An instant clone is created from a running parent VM in memory, which makes the provisioning process incredibly fast. They are always non-persistent and are automatically deleted and recreated on logout, ensuring a pristine desktop for every session. The 2V0-51.19 Exam will test your knowledge of the use cases, requirements, and management processes for each of these clone types.

Preparing a Golden Image VM

The quality of your virtual desktops is directly related to the quality of your golden image VM. The preparation of this golden image is a critical process and a key topic for the 2V0-51.19 Exam. The golden image is a virtual machine that you will use as a template to create all the desktops in a pool. It should have the operating system installed and configured, along with any common applications that all users will need.

The process begins by creating a new virtual machine in vCenter Server and installing a supported version of the Windows operating system. After the OS is installed, you should install VMware Tools, which is a suite of utilities that enhances the performance and management of the VM. Next, you will install the Horizon Agent on the golden image. The agent is the piece of software that allows the VM to communicate with the Connection Server and support the remote display protocols.

Before you can use the golden image, you must optimize it for VDI. This involves disabling unnecessary services, turning off graphical effects, and making other tweaks to reduce the resource consumption of the operating system. There are well-documented best practices and automated tools, like the VMware OS Optimization Tool, to help with this. A properly optimized golden image will result in better performance and higher consolidation ratios in your VDI environment.

Managing User Profiles with User Environment Manager (UEM)

In non-persistent VDI environments, managing user profiles is a critical challenge. VMware User Environment Manager (UEM) is the solution for this, and it is an important subject for the 2V0-51.19 Exam. UEM works by capturing and roaming user-specific settings for the operating system and applications. When a user logs in, UEM applies their saved settings, providing a consistent and personalized experience on a clean, generic desktop.

The configuration of UEM starts with creating a network share where the user profile archives will be stored. You then use the UEM Management Console to create configuration files that define which registry settings and files should be captured for each application. UEM comes with pre-defined templates for many common applications, which simplifies this process. These configuration files are then stored on a central share that is accessed by the UEM agent running on the desktops.

UEM also provides powerful tools for policy management. You can use it to map drives and printers, create shortcuts, and configure other aspects of the user environment based on conditions like user group membership, client device type, or location. This conditional, context-aware management is what makes UEM so powerful. For the 2V0-51.19 Exam, you should understand the architecture of UEM and how to use it to solve the challenges of user persona management.

Publishing Applications with RDSH

In addition to virtual desktops, Horizon 7.7 can also be used to deliver individual applications to users. This is a key capability that is tested on the 2V0-51.19 Exam. Application publishing is typically done using Microsoft Remote Desktop Session Host (RDSH). You will build a server farm of RDSH servers, which are Windows Servers with the Remote Desktop Services role installed. You then install the applications that you want to publish on these servers.

To publish the applications, you create an Application Pool in the Horizon Administrator console. The wizard will allow you to scan an RDSH farm and will present you with a list of the applications that are available to be published from the Start Menu of the servers. You select the applications you want to publish and then entitle users to the pool, just as you would with a desktop pool.

When a user logs into their Horizon Client, they will see the icons for the published applications alongside their virtual desktops. When they launch an application, Horizon will connect them to one of the RDSH servers in the farm, and the application will be seamlessly displayed on their local device, looking and feeling as if it were running locally. This is a very efficient way to deliver applications, as multiple users can share the resources of a single RDSH server.

Entitling Users to Desktops and Applications

Once you have created your desktop and application pools, the final step is to grant users access to them. This process is called "entitling," and it is a fundamental administrative task that you will be tested on in the 2V0-51.19 Exam. Entitlements are managed in the Horizon Administrator console. You can select any pool and add an entitlement, which links the pool to an Active Directory user or group.

It is a best practice to entitle groups rather than individual users. This allows you to manage access by simply adding or removing users from the appropriate Active Directory groups, which is a much more scalable approach. When a user who is a member of an entitled group logs into Horizon, the Connection Server will see that they are authorized to access the resources in that pool and will display the corresponding icons in their client.

You can also configure multi-session behavior for application pools. For example, you can specify that a user can only have one session to a particular application, or you can allow them to open multiple, independent sessions. Properly managing entitlements is key to ensuring that users have access to the resources they need, while also maintaining security by preventing unauthorized access.

Managing the Desktop Lifecycle

Part of managing a VDI environment is managing the lifecycle of the virtual desktops, a topic that is relevant to the 2V0-51.19 Exam. For non-persistent desktops, this lifecycle is very dynamic. Desktops are created, used for a single session, and then destroyed. For linked-clone pools, you can configure the refresh and delete policy. A refresh operation reverts the delta disk back to a clean state. A delete operation removes the linked clone entirely, and a new one will be created when needed.

For persistent desktops, the lifecycle is more static, but you still need to manage them. A key lifecycle task is patching and updating the desktops. For linked-clone and instant-clone pools, this is done by updating the golden image. You install the new patches or applications on the golden image, take a new snapshot, and then instruct Horizon to "recompose" (for linked clones) or "reschedule" (for instant clones) the pool. This will update all the desktops in the pool to the new version in a controlled manner.

For full clones, patching is more like managing physical desktops. You will typically need to use a separate patch management tool to update each desktop individually. Understanding these different lifecycle management processes and the tools that Horizon provides for them is a critical skill for an administrator.

Implementing the Unified Access Gateway (UAG)

Providing secure remote access is a critical requirement for any VDI deployment. The VMware Unified Access Gateway (UAG) is the purpose-built solution for this, and it is a major topic on the 2V0-51.19 Exam. The UAG is a hardened virtual appliance that is deployed in the DMZ of your network. It acts as a secure proxy, providing a single, protected entry point for all external user traffic destined for your internal Horizon environment. This eliminates the need for a traditional VPN, which simplifies the user experience and can improve security.

The UAG is designed to be highly secure out of the box. It runs a minimalist, customized version of Linux and exposes only the necessary services to the internet. When you configure the Horizon edge service on the UAG, it will proxy the various protocols used by Horizon, including the primary XML-API traffic for authentication and the display protocols like Blast Extreme and PCoIP. It inspects this traffic to ensure that it is valid before forwarding it to the internal Connection Servers.

For high availability and scalability, you can deploy multiple UAG appliances behind a load balancer. This ensures that the remote access service remains available even if one appliance fails. The 2V0-51.19 Exam will expect you to understand the architecture of the UAG, the process for deploying and configuring it, and the security benefits it provides over other remote access methods.

Understanding App Volumes

VMware App Volumes is a powerful real-time application delivery and lifecycle management solution that is part of the Horizon suite. A deep understanding of App Volumes is essential for the 2V0-51.19 Exam. App Volumes works by placing applications into read-only virtual disks called AppStacks. These AppStacks are then attached to a user's virtual desktop at login or even in the middle of a session. The applications appear to be natively installed in the operating system, but they are not actually part of the base golden image.

This approach has several significant benefits. It allows you to keep your golden image clean and generic, with only the operating system and the Horizon Agent installed. All applications are managed separately in AppStacks. This dramatically simplifies the management of the golden image and reduces the number of pools you need to maintain. You can have a single golden image and then deliver different sets of applications to different users by assigning them different AppStacks.

App Volumes also includes a feature called Writable Volumes. A Writable Volume is a user-specific virtual disk that can be used to capture user-installed applications and other profile data. This allows you to provide a persistent experience for users on a non-persistent desktop pool. The 2V0-51.19 Exam will test your knowledge of the App Volumes architecture, including the App Volumes Manager and Agent, and how to create and manage AppStacks and Writable Volumes.

Configuring Secure Authentication Methods

Security is paramount in any remote access solution, and the 2V0-51.19 Exam will cover the various secure authentication methods supported by Horizon 7.7. In addition to the standard Active Directory username and password authentication, Horizon supports a range of more secure, multi-factor authentication methods. This is typically implemented by integrating the Unified Access Gateway with a third-party identity provider or authentication server.

One of the most common methods is to use RADIUS (Remote Authentication Dial-In User Service). You can configure the UAG to forward authentication requests to a RADIUS server, which can then enforce two-factor authentication using methods like a one-time password (OTP) from a token or a mobile app. This adds a crucial second layer of security to the login process.

Horizon also supports more advanced authentication methods like smart cards (using the Common Access Card or Personal Identity Verification standards) and biometric authentication. For a seamless single sign-on experience, Horizon offers a feature called True SSO. When True SSO is configured, users who have already authenticated to their corporate identity provider can access their Horizon desktops and applications without having to enter their Active Directory password again. Understanding these different options is key to designing a secure Horizon environment.

Implementing Role-Based Access Control (RBAC)

In an enterprise VDI environment, it is common to have multiple administrators with different responsibilities. The 2V0-51.19 Exam will expect you to know how to use Horizon's Role-Based Access Control (RBAC) features to implement the principle of least privilege. RBAC allows you to create different administrative roles and assign them to users or groups, giving them just the permissions they need to perform their jobs.

Horizon comes with several built-in roles. The Administrators role has full permissions over the entire environment. The Inventory Administrators role can manage desktop pools and machines but cannot change global settings. The Help Desk Administrators role is a limited role designed for support staff, giving them the ability to view user sessions and perform basic tasks like sending messages or restarting desktops.

You can also create custom roles if the built-in roles do not meet your needs. When you create a custom role, you can select from a granular list of permissions. For example, you could create a role for your security team that only allows them to view logs and events. You can also assign roles to specific access groups (folders) in the Horizon inventory, which allows you to delegate administration for a specific set of pools or machines. A solid understanding of RBAC is crucial for maintaining a secure and manageable Horizon deployment.

Optimizing Display Protocols with Policies

The performance of the remote display protocol is key to a good user experience. The 2V0-51.19 Exam requires you to know how to optimize the behavior of Blast Extreme and PCoIP using policies. Horizon allows you to configure these policies at a global level, at the pool level, or even for individual machines. These policies are typically managed using Active Directory Group Policy Objects (GPOs) by importing the Horizon policy templates.

For Blast Extreme, you can configure settings such as the maximum frame rate, the image quality levels, and the H.264 encoding options. For example, you can lower the image quality or frame rate for users on low-bandwidth connections to maintain a responsive session. You can also enable or disable features like client-side caching and H.264 High Color Accuracy.

Similarly, for PCoIP, you can control settings like the session bandwidth limit, the image quality, and whether to allow build-to-lossless, a feature that progressively sharpens the image. You can also configure the redirection of peripherals like USB devices and client printers. The ability to analyze user requirements and network conditions and then apply the appropriate protocol policies is a key skill for a Horizon administrator.

Understanding Cloud Pod Architecture (CPA)

For large-scale or multi-site Horizon deployments, Cloud Pod Architecture (CPA) is an essential feature, and it is an advanced topic on the 2V0-51.19 Exam. CPA allows you to link multiple independent Horizon pods (a pod is a group of Connection Servers, a vCenter, and the associated infrastructure) together into a single, federated environment. This provides several key benefits.

First, CPA provides a single namespace for users. A user can log into any pod and will be directed to their desktop, regardless of which pod it is hosted in. This is achieved through a global entitlement layer that spans all the pods in the federation. You can create global entitlements that can source desktops from pools in multiple pods. This is great for disaster recovery and business continuity, as you can have a pool in one site serve as a backup for a pool in another site.

CPA also provides scalability. A single Horizon pod has a practical limit on the number of desktops it can manage. By linking multiple pods together with CPA, you can scale your environment to tens of thousands of desktops. The 2V0-51.19 Exam will expect you to understand the architecture of CPA, including the inter-pod communication and the global data layer, and the use cases it is designed to solve.

Leveraging Help Desk and Monitoring Tools

Monitoring and troubleshooting are key responsibilities of a Horizon administrator. The 2V0-51.19 Exam will test your knowledge of the tools available for this. The primary tool is the Horizon Administrator console itself. The dashboard provides a high-level overview of the health of your environment, and you can drill down to see the status of individual user sessions, desktops, and servers. The event log provides a detailed audit trail of all activities.

For more advanced troubleshooting, Horizon provides the Help Desk Tool. This is a web-based tool designed for support staff. It allows you to search for a user and see detailed information about their sessions, including the client device they are using, the protocol settings, and performance metrics like latency and bandwidth usage. From the Help Desk Tool, you can perform actions like sending a message to the user, disconnecting or logging off their session, or restarting their virtual desktop.

For deeper performance analysis, you can integrate Horizon with tools like vRealize Operations for Horizon. This provides advanced analytics, performance dashboards, and capacity planning capabilities. Understanding the features and use cases for these different monitoring and troubleshooting tools is essential for maintaining a healthy and performant Horizon environment.

Monitoring the Horizon Environment

Proactive monitoring is essential for maintaining the health and performance of a VMware Horizon environment. The 2V0-51.19 Exam will test your ability to use the native tools to keep a close watch on the system. The primary interface for monitoring is the Horizon Administrator console dashboard. This dashboard provides an at-a-glance view of key metrics, including the number of active sessions, any problematic desktops or servers, and the status of the core infrastructure components like Connection Servers and vCenter Servers.

From the dashboard, you can drill down into more detailed monitoring sections. The Sessions view allows you to see all active user sessions, including details about who is connected, which desktop they are using, and for how long they have been connected. The Events view, which relies on the Event Database, provides a detailed log of all activities in the environment, which is crucial for auditing and troubleshooting. Regular review of these dashboards and logs can help you to spot trends and identify potential issues before they impact users.

You should also monitor the health of the underlying vSphere infrastructure using the vCenter Server. Keep an eye on the CPU, memory, and storage utilization of your ESXi hosts and datastores. A performance issue in vSphere will almost certainly translate into a poor user experience in Horizon. A comprehensive monitoring strategy that covers both the Horizon and vSphere layers is a key theme of the 2V0-51.19 Exam.

Using the Horizon Help Desk Tool

When users report issues with their virtual desktops, the Horizon Help Desk Tool is the first place a support administrator should look. The 2V0-51.19 Exam requires you to be proficient in using this tool to troubleshoot common end-user problems. The Help Desk Tool is a web-based interface that is designed to be used by front-line support staff who may not have full administrative rights to the Horizon environment.

To use the tool, you simply search for the user who is having the issue. The tool will then display a detailed overview of their current and past sessions. You can see important information like the client device they are using, their IP address, the desktop pool they are connected to, and the specific VM they are assigned to. This information is often enough to diagnose simple connectivity issues.

The Help Desk Tool also provides real-time performance metrics for the user's session, including the display protocol being used, the network latency, and the bandwidth consumption. This can help you to determine if a user's poor experience is being caused by a network issue. The tool also allows you to perform basic administrative tasks, such as sending a message to the user, disconnecting their session, or restarting their virtual desktop. Mastering this tool is essential for providing effective user support.

Troubleshooting Common Horizon Issues

The 2V0-51.19 Exam will likely present you with several troubleshooting scenarios, so it is important to have a good understanding of the common issues that can occur in a Horizon environment. One of the most common categories of problems is connection issues. A user might report that they are unable to connect to their desktop. This could be caused by a variety of factors, including DNS issues, firewall problems, or a problem with the Connection Server itself.

Another common issue is a virtual desktop that fails to provision correctly. When you create a new desktop pool, you might find that the VMs get stuck in a "customizing" or "error" state. This is often caused by a problem with the golden image, an issue with the Active Directory integration, or a lack of available IP addresses from your DHCP server. The first place to look for clues is the vCenter Server events for the failed VM.

Performance problems are also a frequent complaint. Users might report that their desktop is slow or unresponsive. This can be one of the most challenging issues to troubleshoot, as it could be caused by a problem at any layer of the stack, from the storage array to the end-user's home network. A systematic approach, using tools like the Help Desk Tool and vRealize Operations, is needed to isolate the bottleneck.

Optimizing Virtual Desktop Performance

Providing a great user experience is the ultimate goal of any VDI deployment. The 2V0-51.19 Exam will test your knowledge of the techniques used to optimize the performance of virtual desktops. Optimization starts with the golden image. As discussed previously, using a tool like the VMware OS Optimization Tool to disable unnecessary services and features in the Windows operating system can significantly reduce the CPU, memory, and I/O overhead of each desktop.

The choice of display protocol and the policies you apply to it also have a major impact on performance. For most use cases, Blast Extreme is the preferred protocol due to its efficiency and adaptability. You should use Group Policy to configure the protocol settings based on your users' needs and network conditions. For example, you can reduce the frame rate and image quality for users on high-latency WAN connections to ensure that the session remains responsive.

Proper sizing of your underlying vSphere infrastructure is also critical. You need to ensure that your ESXi hosts have enough CPU and memory resources to handle the workload of your virtual desktops. You also need a storage solution that can handle the I/O demands of VDI, especially during boot storms when many users are logging in at the same time. Performance tuning is an ongoing process of monitoring, analyzing, and tweaking the environment to deliver the best possible experience.

Managing Horizon with PowerCLI

While the Horizon Administrator console is a great tool for day-to-day management, for large-scale environments or for automating repetitive tasks, a command-line interface is often more efficient. The 2V0-51.19 Exam will expect you to be aware of the automation capabilities available for Horizon. The primary tool for this is VMware PowerCLI, which is a set of PowerShell modules for managing VMware products.

PowerCLI includes a comprehensive set of cmdlets for managing Horizon. You can use it to perform almost any task that you can do in the GUI, such as creating and managing desktop pools, entitling users, and gathering information about the environment. This is incredibly powerful for automation. For example, you could write a PowerCLI script that automatically creates a new desktop pool, configures all its settings, and assigns it to the correct user group.

You can also use PowerCLI for reporting. You can write scripts to query the Horizon API and generate custom reports on things like session usage, desktop inventory, or license consumption. For any administrator who wants to manage their Horizon environment at scale, learning PowerCLI is a valuable investment and demonstrates a higher level of expertise.
