It equips these professionals with the knowledge to design robust, scalable, and cost-effective architectures that meet the demanding requirements of enterprise workloads. This allows them to have more meaningful conversations with clients, addressing their concerns and showcasing the unique benefits of the OCI platform for these specific applications.
The 1z0-1041-20 exam is structured around several critical knowledge domains, each focusing on a different aspect of deploying and managing enterprise workloads on OCI. The most significant domain is dedicated to Oracle E-Business Suite (EBS) on OCI. This section tests your understanding of EBS architecture, migration strategies (such as lift and shift), and the use of tools like EBS Cloud Manager. You will be expected to know the best practices for deploying the application tier, database tier, and associated components in a secure and highly available manner on the cloud infrastructure.
Another major domain covers other key Oracle applications, including PeopleSoft, JD Edwards, and Siebel. While the depth may be less than that for EBS, the 1z0-1041-20 exam requires you to understand the specific considerations for each of these workloads. This includes familiarity with the deployment automation available for these applications on the OCI Marketplace and the recommended architectural patterns. The exam will assess your ability to apply your knowledge to different application scenarios, recognizing the unique needs of each.
The foundation of any cloud deployment is the underlying infrastructure. A substantial portion of the 1z0-1041-20 exam is dedicated to core OCI services. This includes a deep understanding of networking concepts like Virtual Cloud Networks (VCNs), subnets, security lists, and various gateways. It also covers compute options, from virtual machines to bare metal servers, and the different storage services like Block Volumes, File Storage, and Object Storage. You must know how to select and configure these services to build a resilient and performant foundation for the enterprise applications.
Finally, the 1z0-1041-20 exam touches upon cross-cutting concerns such as security, automation, and lifecycle management. This domain tests your knowledge of OCI's security features, including Identity and Access Management (IAM), network security groups, and data encryption. It also assesses your familiarity with infrastructure-as-code principles using tools like Terraform and OCI's Resource Manager. Understanding how to automate deployments and manage the ongoing operations of these complex environments is a key competency for any certified professional.
Oracle E-Business Suite holds a prominent place in the 1z0-1041-20 exam, and for good reason. As one of Oracle's most widely adopted enterprise resource planning (ERP) systems, a large number of customers are looking to migrate their EBS environments to the cloud. Therefore, a deep understanding of EBS architecture and its interaction with the underlying infrastructure is crucial. The exam will test your knowledge of the three-tier architecture of EBS: the client tier, the application tier, and the database tier, and how each of these tiers is mapped to OCI services.
A key focus of the 1z0-1041-20 exam is the EBS Cloud Manager. This is a powerful automation tool available on the OCI Marketplace that simplifies the entire lifecycle management of EBS environments on the cloud. You are expected to know its capabilities in detail. This includes using the Cloud Manager to perform lift-and-shift migrations from on-premises, provision new environments from scratch, and perform ongoing management tasks like cloning, backup, and restore. Questions will likely test your understanding of the steps and prerequisites involved in using this tool effectively.
The exam also delves into the specific OCI services that are recommended for an EBS deployment. This includes choosing the right compute shapes for the application and database tiers, configuring shared storage using the File Storage service for the application tier's shared file system, and setting up a robust networking architecture with public and private subnets. You must understand the best practices for achieving high availability, such as deploying the application tier across multiple availability domains and using a database system like RAC or Data Guard for the database tier.
Furthermore, the 1z0-1041-20 exam covers various migration strategies for moving EBS to OCI. While the EBS Cloud Manager automates the lift-and-shift process, you should also be aware of other methods and the scenarios in which they might be used. This includes understanding the difference between a physical migration and a logical migration and the tools involved in each. A comprehensive grasp of EBS on OCI is the single most important factor for success in this certification exam.
While the 1z0-1041-20 exam is focused on applications, it is built upon the assumption that you have a solid understanding of the core Oracle Cloud Infrastructure services. The Virtual Cloud Network (VCN) is the fundamental building block of any OCI deployment. You must be an expert in VCN design, including the creation of public and private subnets to segregate different application tiers. Knowledge of routing tables, security lists, and network security groups is essential for controlling traffic flow and securing the environment. You also need to understand the different types of gateways, such as Internet Gateway, NAT Gateway, and Dynamic Routing Gateway (DRG), for connecting your VCN to the internet or your on-premises network.
Compute services are another critical area. The 1z0-1041-20 exam requires you to know the different types of compute instances available, from standard virtual machine shapes to high-performance bare metal servers. You need to understand how to choose the appropriate shape based on the performance requirements of the application tier or the database tier. The exam will also test your knowledge of instance lifecycle management, including launching, stopping, and terminating instances, as well as using features like custom images and boot volumes for creating standardized deployments.
Storage is a key component of any enterprise application architecture. The 1z0-1041-20 exam covers the three main storage services in OCI. You must understand Block Volumes, which provide persistent block storage for your compute instances, and their different performance tiers. The File Storage service is crucial for applications like E-Business Suite that require a shared file system for the application tier. Finally, Object Storage is used for storing unstructured data, backups, and archives. You need to know the use cases for each service and how to configure them correctly.
Identity and Access Management (IAM) is the cornerstone of OCI security, and you can expect questions on it in the 1z0-1041-20 exam. You must understand the concepts of users, groups, compartments, and policies. A key skill is the ability to write IAM policies that grant the necessary permissions to users and services while adhering to the principle of least privilege. Understanding how to structure your tenancy using compartments to isolate different environments (e.g., development, testing, production) is a fundamental best practice that will be assessed.
While E-Business Suite is a primary focus, the 1z0-1041-20 exam also validates your knowledge of migrating and managing other significant Oracle enterprise workloads on OCI. PeopleSoft is a key application in this category. You should be familiar with the PeopleSoft Cloud Manager, which is analogous to the EBS Cloud Manager. It provides automation for lifting and shifting on-premises PeopleSoft environments to OCI and for managing their lifecycle thereafter. The exam will expect you to understand its capabilities for provisioning, cloning, and patching PeopleSoft environments in the cloud.
JD Edwards (JDE) EnterpriseOne is another important workload covered in the exam. The approach for JDE on OCI is similar, with automation tools available to streamline the migration and deployment process. The 1z0-1041-20 exam will test your understanding of the reference architectures for deploying JDE on OCI, including the configuration of the various server components like the Enterprise Server, HTML Server, and Database Server. You should be aware of the specific considerations for achieving high availability and disaster recovery for a JDE environment on the cloud platform.
The exam also touches upon other applications like Siebel and Hyperion. For these workloads, the 1z0-1041-20 exam focuses on a conceptual understanding of the benefits and best practices for running them on OCI, even if the level of deployment automation is different from that for EBS or PeopleSoft. You should understand the value proposition, which includes better performance, lower costs, and increased flexibility compared to running these applications on-premises or on other cloud platforms. The key is to be able to articulate why OCI is a suitable platform for these specific Oracle applications.
Across all these applications, a common theme in the 1z0-1041-20 exam is the understanding of reference architectures. You should study the recommended deployment patterns provided by Oracle. These architectures are designed for security, high availability, and performance. They typically involve a multi-tier VCN layout with separate subnets for the web, application, and database layers, the use of load balancers for distributing traffic, and the deployment of components across multiple availability or fault domains to protect against failures. Being able to recognize and explain these architectural patterns is critical for success.
A deep understanding of the Oracle E-Business Suite (EBS) architecture is a prerequisite for success in the 1z0-1041-20 exam. The traditional three-tier architecture of EBS maps directly to Oracle Cloud Infrastructure services. The desktop tier, which consists of the client-side software, remains on the end-user's machine but connects securely to the cloud environment. The exam focuses on how the application tier and database tier are deployed on OCI. It's crucial to understand the function of each component within these tiers to make informed design and deployment decisions in a cloud environment.
The application tier, also known as the middle tier, is a central focus. It contains the web servers, forms servers, and concurrent processing servers that handle the business logic of EBS. In an OCI deployment, these components are installed on one or more compute instances. The 1z0-1041-20 exam will test your knowledge of how to configure these instances for both single-node and multi-node deployments. A critical concept is the shared application file system (APPL_TOP), which must be accessible by all application tier nodes. This is typically implemented using the OCI File Storage service.
The database tier houses the Oracle Database where all the EBS data resides. The 1z0-1041-20 exam requires you to know the different OCI database options available for EBS. This includes running the database on a compute instance (virtual machine or bare metal) or using one of the managed database services like the VM DB System or Exadata Cloud Service. You must understand the pros and cons of each option in terms of performance, management overhead, and high availability features. The choice of database service is one of the most important architectural decisions you will make.
Networking is the glue that holds the architecture together. The 1z0-1041-20 exam will assess your ability to design a secure and efficient network topology for an EBS environment. The best practice is to use a Virtual Cloud Network (VCN) with multiple subnets. A public subnet is typically used for the load balancer, which acts as the entry point to the system, while the application and database tiers are placed in private subnets. This multi-tier design protects the core components from direct exposure to the internet, significantly enhancing security.
The EBS Cloud Manager is a pivotal tool for managing E-Business Suite on OCI, and it is a heavily tested topic on the 1z0-1041-20 exam. This tool is a pre-built virtual machine image that you can deploy from the OCI Marketplace. Once deployed and configured, it provides a powerful web-based interface to automate the entire lifecycle of your EBS environments. You must understand the initial setup process for the Cloud Manager, which involves configuring it to securely communicate with your OCI tenancy using API keys.
One of the primary functions of the EBS Cloud Manager is performing "lift-and-shift" migrations. The 1z0-1041-20 exam requires you to know the detailed steps of this process. It begins with running a discovery script on your on-premises source environment, which gathers its configuration details. This information is then used by the Cloud Manager to create a backup of the source environment, transfer it to OCI Object Storage, and then provision a new, functionally identical environment in the cloud. You should be familiar with the prerequisites and the different phases of this automated migration.
Beyond the initial migration, the EBS Cloud Manager is used for ongoing administration, a key area for the 1z0-1041-20 exam. It simplifies tasks that are traditionally complex and time-consuming. For example, you can use it to create a clone of an existing environment with just a few clicks. This is incredibly useful for creating development or test instances from a production source. The tool also automates the process of creating and managing backups, ensuring that your environments are protected and can be easily restored if needed.
The advanced capabilities of the EBS Cloud Manager are also within the scope of the 1z0-1041-20 exam. This includes its ability to provision a new EBS environment from scratch, either for a fresh installation or for a demonstration. It also has features for managing the infrastructure, such as adding or removing application tier nodes to scale the environment up or down. A thorough understanding of the Cloud Manager's features and how they map to different administrative tasks is essential for anyone preparing for this exam.
Ensuring the continuous availability of a critical application like E-Business Suite is a top priority for any business. The 1z0-1041-20 exam will test your ability to design and implement high availability (HA) and disaster recovery (DR) solutions for EBS on OCI. HA focuses on protecting against failures within a single OCI region, while DR protects against the failure of an entire region. You must understand the distinction and the different OCI services and architectural patterns used for each.
For high availability of the application tier, the best practice is to deploy multiple application tier nodes across different availability domains (ADs) or fault domains (FDs) within a region. An OCI load balancer is then used to distribute traffic across these nodes. If one node fails, the load balancer automatically redirects traffic to the remaining healthy nodes, ensuring uninterrupted service. The 1z0-1041-20 exam expects you to understand this multi-AD/FD architecture and the role of the load balancer in providing application tier resiliency.
The database tier requires its own set of HA solutions. For the highest level of availability, Oracle Real Application Clusters (RAC) can be deployed. A RAC database consists of multiple instances running on different nodes, all accessing the same shared database files. If one node fails, the other nodes in the cluster continue to provide database services. The 1z0-1041-20 exam will test your knowledge of deploying RAC on OCI, typically using bare metal compute shapes or VM DB Systems. You should understand the network requirements and shared storage configuration for a RAC deployment.
For disaster recovery, the primary tool is Oracle Data Guard. Data Guard allows you to maintain a synchronized copy of your primary database in a standby location, which is typically another OCI region. In the event of a catastrophic failure in the primary region, you can perform a switchover or failover to the standby database, allowing your EBS environment to resume operation. The 1z0-1041-20 exam requires you to understand the concepts of Data Guard, including its different protection modes and how to integrate it into an overall DR plan for your EBS environment.
The 1z0-1041-20 exam covers various strategies for migrating an on-premises E-Business Suite environment to Oracle Cloud Infrastructure. The most common and straightforward approach is the "lift-and-shift" migration. This strategy involves moving your existing EBS environment to the cloud with minimal changes to its architecture or configuration. The primary tool for this is the EBS Cloud Manager, which automates the process of backing up the on-premises environment and restoring it on newly provisioned OCI infrastructure. You should be intimately familiar with this automated workflow.
While the EBS Cloud Manager is the preferred tool, you should also be aware of the manual lift-and-shift process for the 1z0-1041-20 exam. This involves using traditional tools and methods, such as RMAN for the database backup and rsync or another utility for copying the application tier file system. This manual approach provides more flexibility but is also more complex and error-prone. Understanding the high-level steps of a manual migration is important for situations where the automated tools cannot be used.
The exam may also touch upon more advanced migration scenarios. For example, a customer might want to upgrade their EBS version or switch their database's operating system as part of the move to the cloud. This type of migration is often referred to as "lift and improve" or "re-platforming." It involves more than just a simple copy of the existing environment. It typically requires a logical migration using tools like Oracle's export/import utilities for the database, followed by a re-installation and configuration of the application tier on the new platform.
Another important consideration in any migration is the cutover strategy. The 1z0-1041-20 exam expects you to understand the different approaches to minimizing downtime during the final switch from the on-premises system to the new cloud environment. This involves careful planning and execution of the final data synchronization and DNS updates. The choice of strategy depends on the business's tolerance for downtime and the complexity of the environment. Being able to weigh the pros and cons of different cutover approaches is a key skill for a solutions architect.
Securing a mission-critical ERP system like E-Business Suite is of paramount importance, and the 1z0-1041-20 exam reflects this. A multi-layered security approach is essential. At the network level, this starts with a properly designed VCN. The best practice, which you must know for the exam, is to place the application and database tiers in private subnets. This means they do not have public IP addresses and cannot be accessed directly from the internet. Access is controlled through a load balancer or a bastion host placed in a public subnet.
Security Lists and Network Security Groups (NSGs) are the primary tools for implementing network firewall rules in OCI. The 1z0-1041-20 exam will test your ability to configure these rules to enforce the principle of least privilege. For example, you should create rules that only allow traffic on specific ports (like the EBS web port) from the load balancer to the application tier, and only allow SQL*Net traffic from the application tier to the database tier. All other traffic should be denied by default. NSGs are generally preferred as they allow for more granular, application-centric rule sets.
At the infrastructure level, security involves protecting the compute instances and the data they store. The 1z0-1041-20 exam expects you to be familiar with OCI's security services. This includes using the Oracle Cloud Agent to apply the latest security patches to the operating systems of your compute instances. For data protection, you must know about OCI's encryption capabilities. All data stored in Block Volumes, File Storage, and Object Storage is encrypted at rest by default. For sensitive data in the database, you can use Transparent Data Encryption (TDE) for an additional layer of security.
Identity and Access Management (IAM) controls who can do what within your OCI tenancy. For the 1z0-1041-20 exam, you need to understand how to create IAM users, groups, and policies to manage access to the infrastructure resources that support your EBS environment. For example, you would create a group for your database administrators and another for your application administrators, and then write specific policies to grant each group the precise permissions they need to perform their jobs, without giving them excessive access to other resources.
Beyond E-Business Suite, the 1z0-1041-20 exam requires proficiency in managing other key Oracle applications, with PeopleSoft being a prominent example. Similar to EBS, Oracle provides a specialized automation tool called the PeopleSoft Cloud Manager. This tool, available from the OCI Marketplace, is central to simplifying the deployment and administration of PeopleSoft environments. A key exam topic is understanding the capabilities of the Cloud Manager for lifting and shifting existing on-premises PeopleSoft instances to the cloud. You should be familiar with the steps involved, from the initial discovery to the final provisioning on OCI.
The architecture of PeopleSoft on OCI is another important area covered in the 1z0-1041-20 exam. The multi-tier architecture, consisting of web servers, application servers, batch schedulers, and a database, needs to be mapped to the appropriate OCI services. The exam will test your knowledge of the reference architectures that Oracle recommends. This typically involves using a load balancer for web traffic, placing application servers on compute instances across multiple fault domains for high availability, and utilizing an OCI database service for the backend. Understanding how these components interact in a cloud environment is critical.
Lifecycle management is a crucial aspect of administering PeopleSoft environments. The 1z0-1041-20 exam will assess your understanding of how the PeopleSoft Cloud Manager automates these tasks. This includes provisioning new environments for development or testing, creating full clones of existing environments, and applying patches and updates using the PeopleTools framework. The ability of the Cloud Manager to streamline these traditionally manual and time-consuming processes is a major benefit of running PeopleSoft on OCI, and you are expected to know these features in detail.
Disaster recovery is just as important for PeopleSoft as it is for any other mission-critical application. For the 1z0-1041-20 exam, you should understand how to design a DR solution for PeopleSoft on OCI. This involves replicating your entire environment to a secondary OCI region. The database would be replicated using a technology like Oracle Data Guard, while the application tier compute instances and their configuration would be replicated using a combination of custom images and automation scripts. The goal is to have a complete, standby environment that can be activated in the event of a disaster in the primary region.
JD Edwards (JDE) EnterpriseOne is another core enterprise application covered in the 1z0-1041-20 exam. Your knowledge of migrating and running JDE on OCI will be tested. Oracle provides automation and reference architectures to facilitate this process. A key tool is the JDE EnterpriseOne One-Click Provisioning, which allows you to quickly deploy a new JDE environment on OCI infrastructure. You should understand the components that are deployed by this tool, including the Enterprise Server, HTML Web Server, Database Server, and Server Manager.
The architectural considerations for JDE on OCI are a key focus of the 1z0-1041-20 exam. You need to be familiar with the recommended deployment patterns for achieving a secure and resilient setup. This includes a VCN with separate subnets for each tier, the use of a load balancer to distribute user traffic to the HTML servers, and the deployment of critical components across multiple availability or fault domains. The exam will assess your ability to design an architecture that meets specific requirements for performance, high availability, and security.
Migration of an existing on-premises JDE environment to OCI is a common scenario that you should be prepared for in the 1z0-1041-20 exam. While the One-Click Provisioning tool is for new deployments, a migration involves moving your existing data and configurations. This typically follows a lift-and-shift approach. The database can be migrated using tools like RMAN or Data Pump, and the JDE application components can be re-installed on new OCI compute instances, after which your existing configuration and data are applied. Understanding the high-level steps of this process is important.
As with other enterprise applications, performance and scalability are critical for JDE. The 1z0-1041-20 exam requires you to understand how to leverage OCI's features to meet these demands. This includes selecting the right compute shapes for the different JDE servers based on their workload characteristics. For scalability, you can add more HTML servers behind the load balancer to handle an increasing number of users. The performance of the database is also crucial, and choosing the right OCI database service and storage options is a key design decision that will be tested.
The 1z0-1041-20 exam broadens its scope to include other important applications like Siebel CRM and Oracle Hyperion Enterprise Performance Management (EPM). For Siebel, you are expected to understand the benefits of running it on OCI and the recommended architectural practices. The multi-tier architecture of Siebel, including the Siebel Web Server Extension (SWSE), Siebel Server, and Gateway Name Server, must be deployed on a properly designed OCI network with appropriate security controls. The exam will test your conceptual understanding of how to build a resilient and secure Siebel environment.
High availability for Siebel on OCI is a key topic. This involves deploying redundant components across different fault domains. For example, you would have multiple Siebel Servers and multiple SWSE instances running on separate compute instances, with a load balancer distributing traffic between them. The 1z0-1041-20 exam will assess your knowledge of this architectural pattern. For the Siebel Gateway Name Server, which can be a single point of failure, you need to understand the clustering options available to make it highly available.
Oracle Hyperion is another specialized workload that the 1z0-1041-20 exam touches upon. Running Hyperion on OCI provides benefits in terms of performance, scalability, and cost-effectiveness. The exam will test your understanding of the reference architectures for deploying the various Hyperion components, such as the web tier, the application tier (e.g., Planning, Financial Management), and the database tier. As with other applications, a secure network design with private subnets for the application and database components is a fundamental best practice.
The migration of on-premises Hyperion environments to OCI is a relevant scenario for the exam. This is typically a lift-and-shift process, but it requires careful planning due to the complexity and interconnectedness of the various Hyperion products. You should have a high-level understanding of the migration process, which involves moving the database, re-hosting the application components on OCI compute instances, and re-configuring the environment to work in the new cloud infrastructure. The key takeaway for the 1z0-1041-20 exam is to understand the general principles and best practices for running these specialized workloads on OCI.
The OCI Marketplace is a central catalog of software and solutions that can be easily deployed on Oracle Cloud Infrastructure, and it is a key resource for the enterprise workloads covered in the 1z0-1041-20 exam. The Marketplace contains pre-built images and stacks provided by both Oracle and third-party vendors. You must understand the role of the Marketplace in simplifying and accelerating the deployment of complex applications like E-Business Suite, PeopleSoft, and JD Edwards. It eliminates the need for manual installation and configuration of many components.
For the 1z0-1041-20 exam, you need to be particularly familiar with the key Oracle application images available on the Marketplace. This includes the EBS Cloud Manager, the PeopleSoft Cloud Manager, and the JDE One-Click Provisioning images. The exam will test your knowledge of how to find and launch these solutions. You should understand that launching a Marketplace solution often involves using a Resource Manager stack, which is a Terraform script that automates the provisioning of all the necessary infrastructure resources, such as compute instances, VCNs, and storage.
The benefits of using the Marketplace are a key concept to grasp. The primary advantage is automation. Instead of spending days or weeks manually setting up an environment, you can have a fully functional application stack up and running in a matter of hours. This significantly reduces the potential for human error and ensures that the deployment follows Oracle's best practices. The 1z0-1041-20 exam will expect you to be able to articulate these benefits and understand why using the Marketplace is the recommended approach for deploying these applications.
Beyond the initial deployment, the Marketplace can also play a role in the ongoing management of the applications. Some solutions may receive updates through the Marketplace, providing an easy way to apply patches or upgrade to new versions. Understanding the lifecycle of a Marketplace application is part of the knowledge required for the 1z0-1041-20 exam. You should be familiar with the process of updating a deployed stack and managing the resources it created. The Marketplace is a fundamental tool for anyone working with Oracle enterprise applications on OCI.
While the 1z0-1041-20 exam covers specific applications, it also tests your understanding of the general architectural principles that apply to all enterprise workloads on OCI. The principle of designing for failure is paramount. This means you should always assume that individual components can and will fail. To mitigate this, you should design your architecture with redundancy. This involves deploying multiple instances of your application servers across different fault domains and using a load balancer to distribute traffic. For the database, it means using technologies like RAC or Data Guard.
Security is another universal principle. A defense-in-depth strategy is crucial. This starts with a secure network design using a VCN with private subnets for sensitive components. It then adds layers of security with Network Security Groups, IAM policies, and encryption of data at rest and in transit. The 1z0-1041-20 exam will expect you to apply these security principles to any given application scenario. You should always be thinking about how to protect the confidentiality, integrity, and availability of the application and its data.
Scalability is a key advantage of the cloud, and the 1z0-1041-20 exam requires you to know how to design for it. This involves both vertical and horizontal scaling. Vertical scaling means increasing the resources of a single compute instance (e.g., adding more CPU or memory). OCI makes it easy to change the shape of a VM to achieve this. Horizontal scaling means adding more instances to your application tier. Your architecture should be designed to support this, typically by using a load balancer and a shared file system, so that new application servers can be easily added to the pool.
Finally, the principle of automation is a recurring theme. The 1z0-1041-20 exam emphasizes the use of tools to automate deployment and management tasks. This includes using the application-specific Cloud Managers, the OCI Marketplace, and infrastructure-as-code tools like Terraform. An automated approach leads to more consistent, repeatable, and reliable environments. Understanding how and when to apply automation is a key competency for a cloud professional and a major topic in this certification.
A robust and secure network is the foundation for any enterprise application deployment on Oracle Cloud Infrastructure, making it a critical domain for the 1z0-1041-20 exam. The Virtual Cloud Network (VCN) is the private network you create in OCI. You must have an expert-level understanding of how to design a VCN, which includes selecting an appropriate CIDR block that does not overlap with your on-premises network. The exam will test your ability to segment this VCN into multiple subnets. Best practice dictates creating separate subnets for each tier of your application architecture, such as a web tier, an application tier, and a database tier.
The 1z0-1041-20 exam requires you to differentiate between public and private subnets. A public subnet is one where the instances can have public IP addresses and are directly reachable from the internet, typically through an Internet Gateway. A private subnet is one where instances do not have public IPs and cannot be reached from the internet. Enterprise application components like application servers and databases should always be placed in private subnets for security. You must know how to configure route tables and gateways (Internet, NAT, Service) to control the flow of traffic into and out of these subnets.
Network security is implemented using Security Lists and Network Security Groups (NSGs). The 1z0-1041-20 exam will expect you to know the difference and when to use each. Security Lists are attached to subnets and apply to all resources within that subnet, making them suitable for broad security postures. NSGs are attached to individual network interfaces (VNICs) and allow for more granular, application-specific rule sets. For complex enterprise applications, NSGs are generally the preferred method for defining the specific ports and protocols that need to be open between different application tiers.
Connectivity between your on-premises data center and your OCI VCN is another crucial topic. The 1z0-1041-20 exam will test your knowledge of the two primary ways to achieve this: a site-to-site VPN and FastConnect. A VPN provides an encrypted connection over the public internet, which is suitable for development or less performance-sensitive workloads. FastConnect provides a private, dedicated connection, offering higher bandwidth and more reliable performance, making it the recommended choice for production enterprise workloads. You should understand the use cases and basic configuration of both options.
The compute service provides the processing power for your enterprise applications, and the 1z0-1041-20 exam will assess your ability to choose the right compute shape for each component of your workload. OCI offers a wide range of compute options, from virtual machines (VMs) to dedicated bare metal servers. You need to understand the characteristics of each. VMs offer flexibility and are suitable for most application tier components. Bare metal servers provide the highest level of performance and isolation, making them ideal for performance-intensive database workloads or applications with specific licensing constraints.
Within the VM offerings, OCI provides different shapes optimized for various use cases. The 1z0-1041-20 exam expects you to be familiar with these. Standard shapes offer a balanced mix of CPU and memory. DenseIO shapes provide high-performance local NVMe SSD storage, which is excellent for databases that require very low latency. GPU shapes are specialized for workloads that require graphics processing. You must be able to analyze the requirements of an application component, like a concurrent processing server or a database instance, and select the most appropriate and cost-effective compute shape.
Instance lifecycle management is another key area covered in the exam. You should know the process of launching a compute instance, which involves selecting a shape, a VCN and subnet, and an operating system image (either a platform image or a custom image). You must also understand the difference between stopping and terminating an instance. Stopping an instance de-allocates the CPU and memory but preserves the boot volume, allowing you to restart it later. Terminating an instance permanently deletes it and its boot volume. This knowledge is crucial for day-to-day operations and cost management.
For scalability and high availability, the 1z0-1041-20 exam requires you to understand concepts like instance pools and instance configurations. An instance configuration is a template that defines the settings for creating a new compute instance. An instance pool uses this template to create and manage a group of identical instances. This is particularly useful for the application tier of your enterprise workload, as it allows you to easily scale out by adding more instances to the pool. The pool can also be configured to distribute the instances across different availability or fault domains, enhancing resiliency.
Storage is a fundamental component of any IT system, and the 1z0-1041-20 exam will thoroughly test your knowledge of the various storage services available on OCI. Block Volume is the primary storage service for compute instances. It provides persistent, high-performance block storage that can be attached to your VMs or bare metal servers. You need to understand the different performance tiers available for Block Volumes (Basic, Balanced, Higher Performance) and how to choose the right one based on the IOPS and throughput requirements of your workload. The database datafiles and log files for an enterprise application are typically stored on Block Volumes.
The OCI File Storage service is critically important for many of the enterprise applications covered in the 1z0-1041-20 exam. Applications like E-Business Suite require a shared file system for the application tier (APPL_TOP) that is accessible by all the application server nodes. The File Storage service provides a fully managed, network-attached storage (NAS) solution based on the NFS protocol. You must know how to create a file system, create a mount target in your VCN, and configure your compute instances to mount and use the shared file system.
Object Storage is the third major storage service you need to master for the 1z0-1041-20 exam. It is designed for storing large amounts of unstructured data. Its primary use case in the context of enterprise workloads is for backups. For example, you would configure your database backups (like RMAN backups) to be sent to an Object Storage bucket. It is also used during migrations, where the on-premises backup is first uploaded to Object Storage before being restored in OCI. You should understand the difference between the standard (hot) and archive (cold) storage tiers and their respective use cases and pricing.
Data management and protection features for these storage services are also key exam topics. For Block Volumes, this includes the ability to create backups and clones. Backups are point-in-time copies that can be used to restore a volume, while clones are new, independent volumes created from a source volume. The 1z0-1041-20 exam will expect you to understand these features and how they can be used as part of your overall data protection strategy for the enterprise application.
The database is the heart of any Oracle enterprise application, and choosing the right database service on OCI is one of the most critical decisions. The 1z0-1041-20 exam requires a comprehensive understanding of the available options. The most basic option is to install the Oracle Database software on a standard OCI compute instance (VM or bare metal). This gives you maximum control but also requires you to manage the underlying OS, patching, and backups yourself. This is known as the "database on infrastructure" model.
For a more managed experience, OCI offers DB Systems. These are managed services that automate many of the routine database administration tasks. The 1z0-1041-20 exam will test your knowledge of VM DB Systems, which run on virtual machines, and Bare Metal DB Systems, which run on dedicated physical servers. When you provision a DB System, OCI handles the underlying infrastructure provisioning and provides tools for easy patching, backup, and creation of Data Guard standby databases. You must understand the features and limitations of these DB Systems.
For the highest levels of performance, scalability, and availability, OCI offers the Oracle Exadata Cloud Service. This service provides the full power of the Exadata Database Machine in a cloud consumption model. The 1z0-1041-20 exam will expect you to know when to recommend Exadata. It is the ideal platform for very large and performance-critical E-Business Suite or PeopleSoft databases. You should have a high-level understanding of the unique features of Exadata, such as Smart Scans and Storage Indexes, that contribute to its extreme performance.
Finally, the exam covers Oracle Real Application Clusters (RAC), which is Oracle's premier solution for database high availability and scalability. You must understand that RAC can be deployed on OCI, either on Bare Metal DB Systems or VM DB Systems. The 1z0-1041-20 exam will test your knowledge of the requirements for a RAC deployment on OCI, such as the need for a VCN with multiple private subnets for the application, backup, and interconnect traffic. Understanding how RAC provides protection against instance failure is a key concept for designing highly available enterprise application architectures.
