A Guide to the 70-621 Exam and Windows Vista Installation

The Microsoft 70-621 Exam, "Microsoft Windows Vista, Configuring," is the certification test designed for IT professionals who support the Windows Vista operating system in a business environment. This exam is a core component of the Microsoft Certified Technology Specialist (MCTS) credential for Windows Vista. The target audience for this certification includes desktop support technicians, help desk professionals, and system administrators. The exam focuses on the practical, hands-on skills required to install, configure, secure, and maintain Windows Vista clients as part of a corporate network.

Passing the 70-621 Exam validates a candidate's proficiency in a wide range of configuration tasks. It demonstrates that an individual has the necessary knowledge to deploy the operating system, manage hardware and software, configure network connectivity, and troubleshoot common issues. While Windows Vista is an older operating system, the concepts and skills tested, such as managing security policies, device drivers, and network settings, provide a foundational understanding that is relevant to the support of all subsequent Windows client operating systems.

Windows Vista Editions and Features

A key foundational topic for the 70-621 Exam is a clear understanding of the different editions of Windows Vista and their key features. The primary editions for business use were Windows Vista Business, Enterprise, and Ultimate. The Business edition was aimed at small and medium-sized businesses, while the Enterprise edition, available only through volume licensing, included additional features like BitLocker Drive Encryption and support for multiple languages. Ultimate edition combined all the features of both the business and home premium editions.

Windows Vista introduced several landmark features that you must understand for the 70-621 Exam. The most significant of these was User Account Control (UAC), a new security model designed to protect the operating system from unauthorized changes. Other key features included the visually rich Aero user interface, the powerful new Windows Search for instant file searching, and the built-in Windows Firewall with advanced security.

Planning a Windows Vista Installation

Before deploying Windows Vista, an IT professional must engage in careful planning, and the 70-621 Exam requires knowledge of this process. The first step is to ensure that the target hardware meets the minimum requirements for the operating system. This includes having a sufficiently powerful CPU, enough RAM, and, for the full visual experience, a graphics card that supports the Windows Aero interface. You must also plan the installation method. You can perform a clean installation, which erases the hard drive, or an in-place upgrade from a compatible version of Windows XP.

To assist in this planning, Microsoft provided the Windows Vista Upgrade Advisor. This tool could be run on a Windows XP machine to scan its hardware and software and produce a report detailing any potential compatibility issues. The report would identify devices that might need new drivers and applications that might not run correctly on Windows Vista, allowing an administrator to address these issues before starting the deployment.

Performing a Clean Installation

A clean installation is the process of installing Windows Vista on a new computer or on a computer where you intend to erase the existing operating system. This is a fundamental skill tested in the 70-621 Exam. The process begins by booting the computer from the Windows Vista installation media (typically a DVD). The setup wizard then guides you through the process of selecting the language, time, and keyboard preferences.

A critical step in the process is disk management. You will be prompted to choose the disk and partition where you want to install the operating system. You have the option to delete existing partitions, create new ones, and format them with the NTFS file system. After the files are copied and the installation is complete, the wizard will guide you through the initial Out-of-Box Experience (OOBE), where you set up the first user account and computer name.

Upgrading to Windows Vista

An in-place upgrade is the process of installing Windows Vista on top of an existing Windows XP installation while preserving the user's files, settings, and compatible applications. The 70-621 Exam requires you to understand the pros and cons of this method. To perform an upgrade, you run the setup program from within the running Windows XP operating system. The setup wizard will then perform a series of compatibility checks before beginning the upgrade process.

While an upgrade is often more convenient for the end-user as it preserves their environment, it also carries more risk. There is a greater chance of encountering application or driver compatibility issues. Any existing malware or system instability from the old operating system can also be carried over to the new installation. For these reasons, in many corporate environments, a clean install combined with a separate user data migration is the preferred method.

Migrating User Data and Settings

When performing a clean installation, you need a method to transfer the user's important data and settings from their old computer to the new one. The 70-621 Exam covers the primary tool for this purpose: the User State Migration Tool (USMT). USMT is a powerful, scriptable command-line utility designed for large-scale, automated migrations. It consists of two main executables.

First, you run the ScanState.exe tool on the source computer. This tool scans the computer, collects all the user profiles, files, and application settings as specified in a set of XML configuration files, and saves this information to a central network store. After you have installed Windows Vista on the new computer, you run the LoadState.exe tool. This tool connects to the network store, retrieves the saved user state, and applies it to the new operating system, restoring the user's familiar environment.

Automating Installation with Windows AIK

For deploying Windows Vista to hundreds or thousands of computers in an enterprise, manual installation is not feasible. The 70-621 Exam requires you to be aware of the tools used for automated deployment. The primary toolset for this is the Windows Automated Installation Kit, or WAIK. WAIK provides a collection of tools and documentation to help IT professionals customize and automate the installation of Windows Vista.

The core of an automated installation is the use of an answer file. This is an XML file, typically named unattend.xml, that contains the answers to all the questions the setup wizard would normally ask, such as the product key, computer name, and disk configuration. To create this answer file, you use a tool within the WAIK called the Windows System Image Manager (Windows SIM). This allows you to build a complete, unattended installation that can be deployed across your organization.

Preparing for the 70-621 Exam's Installation Topics

To prepare for the installation and deployment section of the 70-621 Exam, your focus should be on the practical differences and decision points. You must be able to clearly articulate the differences between the main Windows Vista editions, especially which features are exclusive to the Enterprise and Ultimate editions. You should also be able to explain the pros and cons of choosing an in-place upgrade versus a clean installation with a user state migration.

While you may not need to memorize every command-line switch, you must understand the purpose of the key enterprise deployment tools. Know that USMT is used for migrating user settings and that the WAIK and answer files are used for automating the operating system installation. A solid grasp of these foundational deployment concepts is essential for any IT professional and is a key requirement for success on the 70-621 Exam.

Managing Devices and Drivers

A core responsibility of a desktop support professional is managing hardware devices and their drivers. The 70-621 Exam places a strong emphasis on this skill. The primary tool for hardware management in Windows Vista is the Device Manager. This console provides a centralized, hierarchical view of all the hardware components installed in the computer. It uses icons to indicate the status of each device, making it easy to spot any hardware that is not functioning correctly.

Within Device Manager, you can perform several key tasks. You can update a device's driver to a newer version, or if a new driver is causing problems, you can use the "Roll Back Driver" feature to revert to the previously installed version. You must also understand the concept of driver signing. Windows Vista uses driver signing to verify the integrity and authenticity of driver files, which helps to ensure system stability and protect against malicious software.

Configuring Mobile Devices and Power Settings

The 70-621 Exam covers the configuration of settings that are specific to mobile computers, such as laptops. Windows Vista introduced the Windows Mobility Center, which provides a convenient, single location for managing common mobile settings like display brightness, wireless network status, and power options. This makes it easy for users to quickly adjust their settings when they are on the go.

Power management is a particularly important topic. You must know how to configure the different power plans that are available: Balanced, Power saver, and High performance. Each of these plans represents a different trade-off between energy consumption and system performance. You should also be familiar with the advanced power settings, which allow you to configure detailed behaviors, such as how long the computer should wait before turning off the display or putting the hard disk to sleep.

Managing Application Compatibility

One of the major challenges with any new operating system is ensuring that older applications continue to work correctly. The 70-621 Exam requires you to know the tools and techniques for managing application compatibility in Windows Vista. Many applications that were designed for Windows XP would fail to run on Vista due to the new security model or other system changes.

The primary tool for addressing these issues is the Program Compatibility Wizard. This wizard allows you to apply compatibility settings to an application's executable file. For example, you can configure an application to run in a compatibility mode that emulates the environment of a previous version of Windows, such as Windows XP Service Pack 2. You can also apply specific fixes, or "shims," to address known compatibility problems with certain applications.

Configuring Software Restriction Policies and AppLocker

In a corporate environment, it is often necessary to control which applications users are allowed to run. The 70-621 Exam covers the technologies used for this purpose. The primary tool available in all business editions of Windows Vista is Software Restriction Policies (SRP). SRP allows an administrator to create rules that either allow or deny the execution of software.

These rules can be based on several criteria, such as the file's digital signature, its location (path), or its unique hash value. For example, you could create a policy that only allows applications stored in the "Program Files" folder to run. In the Enterprise and Ultimate editions, Windows Vista introduced a new, more flexible tool called AppLocker. AppLocker builds upon SRP and allows for the creation of rules based on the publisher of the application, making it easier to manage.

Configuring Network Connectivity

A fundamental skill for any IT professional, and a key topic for the 70-621 Exam, is the configuration of network connectivity. In Windows Vista, the central hub for all network-related tasks is the Network and Sharing Center. From this single console, you can view the status of your network connections, configure new connections, and troubleshoot connectivity problems.

You must be proficient in configuring both IPv4 and IPv6 settings. This includes knowing how to manually assign an IP address, subnet mask, default gateway, and DNS server addresses. You should also understand the difference between the three network locations: Public, Private, and Domain. Windows Vista uses the network location to automatically apply the appropriate firewall and security settings for the network you are connected to.

Configuring Windows Firewall

Windows Vista introduced a significantly improved firewall compared to its predecessor. The 70-621 Exam requires a solid understanding of this new firewall's capabilities. The Windows Firewall in Vista is a stateful, two-way firewall, which means it filters both incoming (inbound) and outgoing (outbound) traffic. The firewall is managed through the "Windows Firewall with Advanced Security" Microsoft Management Console (MMC) snap-in.

Within this console, you can create detailed firewall rules to allow or block traffic for a specific program, a specific protocol, or a specific port number. A key concept is the use of firewall profiles. There are separate profiles for the Domain, Private, and Public network locations. This allows you to have a very restrictive set of rules when you are connected to a public network, like a coffee shop, and a more lenient set of rules when you are connected to your trusted corporate domain network.

Configuring Remote Access

The 70-621 Exam covers the configuration of remote access features, which are essential for remote administration and support. The primary tool for remote administration is Remote Desktop. You must know how to enable Remote Desktop on a client computer to allow an administrator to connect to it and take full control of the desktop session. This includes understanding the security options, such as requiring Network Level Authentication.

For user support scenarios, Windows Vista provides Remote Assistance. This feature allows a user who is having a problem to send an invitation to a help desk professional. The support professional can then connect to the user's computer, view their screen, and, with the user's permission, take control of the mouse and keyboard to help them resolve the issue. Understanding the difference in use cases between Remote Desktop and Remote Assistance is important.

Preparing for the 70-621 Exam's Configuration Topics

To prepare for the hardware, application, and networking configuration section of the 70-621 Exam, your focus should be on the key management consoles. You must be comfortable navigating and using the Device Manager for hardware issues, the Network and Sharing Center for network settings, and the "Windows Firewall with Advanced Security" console for firewall rules.

For application management, the most important concepts are the Program Compatibility Wizard and its role in running legacy applications, and the purpose of Software Restriction Policies for controlling software execution. Hands-on practice is essential. In a virtual lab, practice changing IP address settings, creating a firewall rule to block a specific program, and enabling Remote Desktop. This practical experience is the best way to prepare for the scenario-based questions on the 70-621 Exam.

Understanding User Account Control (UAC)

User Account Control, or UAC, is arguably the most significant new security feature in Windows Vista, and it is a topic you must master for the 70-621 Exam. The primary goal of UAC is to improve the security of the operating system by running all users, including administrators, with standard user privileges by default. When an administrative task needs to be performed, such as installing software or changing a system setting, UAC will prompt for approval or credentials.

This process is called elevation. For an administrator, the prompt is a simple consent prompt. For a standard user, the prompt will require them to enter the credentials of an administrator account. This model prevents malicious software from making changes to the system silently in the background. The 70-621 Exam will expect you to understand the different UAC prompt behaviors and how they can be configured using the Local Security Policy editor.

Configuring File and Folder Permissions

A fundamental aspect of securing any operating system is controlling access to files and folders. The 70-621 Exam requires a solid understanding of the NTFS permission model used by Windows Vista. NTFS provides a granular set of permissions, such as Read, Write, Modify, and Full Control, that can be assigned to users and groups. These permissions control exactly what actions a user can perform on a file or folder.

When a file or folder is accessed over the network, you must also consider the share permissions. The share permissions are simpler than NTFS permissions and are applied at the shared folder level. It is a critical concept for the 70-621 Exam to understand that when a resource is accessed over the network, the most restrictive of the two permission sets (share and NTFS) will be applied. This is known as the effective permissions.

Implementing BitLocker Drive Encryption

For protecting data on lost or stolen computers, especially laptops, Windows Vista Enterprise and Ultimate editions introduced BitLocker Drive Encryption. The 70-621 Exam covers the purpose and implementation of this powerful security feature. BitLocker provides full volume encryption, which means it encrypts the entire Windows operating system volume, including all system files, user files, and even the hibernation and paging files. This protects the data even if the hard drive is removed from the computer.

To provide the most secure implementation, BitLocker is designed to work with a hardware component called a Trusted Platform Module, or TPM. The TPM is a microchip on the motherboard that securely stores the encryption keys and verifies the integrity of the boot components before releasing the keys. You must also know about the recovery options for BitLocker, such as the numerical recovery key, which is essential if the TPM fails or the boot files are changed.

Configuring Windows Defender

Windows Vista was the first version of Windows to include a built-in anti-spyware solution called Windows Defender. The 70-621 Exam will expect you to be familiar with its configuration and use. Windows Defender is designed to protect the computer from spyware and other potentially unwanted software. It provides real-time protection, which monitors key areas of the operating system and alerts you if a program tries to make a suspicious change.

In addition to real-time protection, you can configure Windows Defender to run scheduled scans of the entire computer to look for any existing spyware. When spyware is detected, it is moved to a safe location called the quarantine. From the Windows Defender interface, you can then choose to permanently remove the quarantined items or restore them if you believe they were a false positive.

Managing Windows Updates

Keeping the operating system up to date with the latest security patches is a critical maintenance task for any IT professional. The 70-621 Exam covers the management of Windows Updates. The primary tool for this on a standalone client is the Windows Update applet in the Control Panel. From here, you can manually check for new updates, review the available updates, and choose which ones to install.

You can also configure the automatic behavior of Windows Update. The recommended setting is to have Windows automatically download and install important updates at a scheduled time. In a corporate environment, you typically do not want each client computer to download updates directly from the internet. Instead, you would use a server product called Windows Server Update Services (WSUS). You would then configure your Vista clients, using Group Policy, to get their updates from your internal WSUS server.

Monitoring System Performance

Windows Vista introduced a new and greatly improved tool for performance monitoring called the Reliability and Performance Monitor. A solid understanding of this tool is required for the 70-621 Exam. This single console brings together several different monitoring utilities. The Resource View provides a real-time dashboard of your system's CPU, disk, network, and memory usage, making it easy to spot which processes are consuming the most resources.

The Performance Monitor component allows you to track detailed performance counters over time, which is useful for in-depth analysis and trend reporting. A brand-new feature was the Reliability Monitor, which provides a simple, graphical timeline of your system's stability. It tracks important events like application failures, driver installations, and Windows updates, and it calculates a stability index to give you an at-a-glance view of your system's health.

Using System Restore and Backup Tools

To recover from system problems, Windows Vista provides two key tools that are covered in the 70-621 Exam. The first is System Restore. System Restore automatically creates "restore points" before major system events like a driver or application installation. If the new software causes a problem, you can use System Restore to revert the computer's system files and registry settings back to the state they were in at the time the restore point was created, without affecting your personal data files.

For more comprehensive data protection, Windows Vista introduced the Backup and Restore Center. This tool allows you to schedule regular backups of your personal data files to an external hard drive or a network location. The Business, Enterprise, and Ultimate editions also included a feature called Windows Complete PC Backup, which creates a full system image backup. This image can be used to restore the entire computer, including the operating system and all applications, in the event of a hard drive failure.

Preparing for the 70-621 Exam's Security and Maintenance Topics

When preparing for this section of the 70-621 Exam, your highest priority should be to master User Account Control (UAC). You must be able to explain what it is, why it was introduced, and how the elevation process works for both administrators and standard users. For the other security features, focus on the primary use case: use NTFS and share permissions to control access to files, and use BitLocker to protect data on lost or stolen laptops.

For the maintenance topics, the most important new tool to understand is the Reliability and Performance Monitor. Be familiar with its different components, especially the new Reliability Monitor and its stability index. Practice using System Restore and the Backup and Restore Center in a lab environment to get a feel for how these recovery tools work. A practical understanding of these core security and maintenance tasks is essential.

The Windows Vista Boot Process

A significant architectural change in Windows Vista, and a key topic for the 70-621 Exam, was the introduction of a new boot process. Previous versions of Windows, like XP, used a simple text file called boot.ini to manage the boot menu. Windows Vista replaced this with a more robust and secure firmware-independent database called the Boot Configuration Data, or BCD. The BCD store contains all the information needed to load the operating system, such as the location of the boot files.

The boot process itself is managed by new components like the Windows Boot Manager (bootmgr) and the Windows OS Loader (winload.exe). For an administrator, the most important change is the new tool used to manage the boot configuration. Instead of editing a text file, you must now use the command-line utility bcdedit.exe. You must be familiar with the purpose of this tool and its basic syntax for the 70-621 Exam.

Using the Windows Recovery Environment (WinRE)

When Windows Vista fails to start correctly, you need to use the Windows Recovery Environment, or WinRE. A deep understanding of WinRE and its tools is essential for the 70-621 Exam. WinRE is a minimal version of the Windows operating system that can be booted from the installation media or from a dedicated recovery partition on the hard drive. It provides a graphical interface with a suite of powerful recovery tools.

The most important tool in WinRE is Startup Repair. This tool automatically scans for common startup problems, such as missing or corrupt boot files or registry errors, and attempts to fix them automatically. Other tools available in WinRE include System Restore, Windows Complete PC Restore (for restoring a system image backup), the Windows Memory Diagnostic Tool, and a command prompt for advanced manual troubleshooting.

Troubleshooting Application Failures

When an application crashes or fails to launch, an IT professional needs a systematic way to troubleshoot the problem. The 70-621 Exam will test your knowledge of the tools available for this in Windows Vista. A great place to start is the Reliability Monitor. As discussed in the previous part, this tool provides a simple timeline view of all application failures, hangs, and other significant system events, making it easy to see if the problem started after a specific software installation or update.

For more detailed information, you need to use the Event Viewer. The Event Viewer contains several logs, with the "Application" and "System" logs being the most important for troubleshooting. When an application crashes, it will typically record a detailed error message in the Application log, which can provide valuable clues about the root cause of the problem.

Troubleshooting Hardware and Driver Issues

Troubleshooting hardware problems is a core skill for any desktop support professional. The 70-621 Exam requires you to be proficient with the tools for this task. As always, the primary tool is the Device Manager. If a hardware component is not working, Device Manager will typically display a yellow exclamation mark or a red "X" next to the device. The properties of the device will show a specific error code, which can be used to diagnose the problem.

For more advanced driver troubleshooting, Windows Vista includes a tool called the Driver Verifier. This tool is designed to stress-test device drivers to find potential bugs or stability issues that might not be apparent during normal operation. It should be used with caution, as it can cause system instability, but it is a powerful tool for diagnosing intermittent problems that are suspected to be caused by a faulty driver.

Troubleshooting Network Connectivity

When a user reports that they cannot connect to the network or the internet, you need a standard set of tools to diagnose the problem. The 70-621 Exam will expect you to be comfortable with the fundamental command-line networking utilities. The ipconfig command is used to view the computer's IP address configuration. The ping command is used to test basic connectivity to another device, like a server or a gateway. The tracert command is used to trace the path that network traffic takes to a destination.

In addition to these command-line tools, Windows Vista also provides the Network Diagnostics tool, which is integrated into the Network and Sharing Center. This tool can automatically diagnose and, in some cases, resolve common network connectivity problems, making it a good first step for any network troubleshooting task.

Configuring Internet Explorer 7

The version of Internet Explorer included with Windows Vista was IE7, and the 70-621 Exam covers its key configuration and security features. A major new security feature in IE7 was Protected Mode. When enabled, Protected Mode runs the browser in a low-privilege, "sandboxed" environment. This makes it much more difficult for malicious websites to install software or make changes to your computer.

Other key security features include the Phishing Filter, which helps to protect users from fraudulent websites, and a more robust system for managing browser add-ons. You should also be familiar with the configuration of security zones (Internet, Local intranet, Trusted sites, and Restricted sites) and how they are used to apply different levels of security settings to different types of websites.

Configuring Offline Files

For mobile users who need to work with files stored on a network share, the Offline Files feature is essential. The 70-621 Exam requires you to know how to configure and manage this feature. Offline Files allows a user to cache copies of network files and folders on their local laptop. They can then work with these files even when they are disconnected from the corporate network, such as when they are on an airplane or at home.

To enable this, a user simply right-clicks on a network folder and selects "Always available offline." Windows then creates a local copy of the files. All changes the user makes are saved to this local copy. When the user reconnects to the network, the Sync Center automatically synchronizes the changes between the local copy and the server, ensuring that both locations are up to date.

Preparing for the 70-621 Exam on Troubleshooting

The troubleshooting section of the 70-621 Exam is highly practical. The best way to prepare is to practice solving problems in a lab environment. Intentionally create common issues: delete a boot file and then use WinRE's Startup Repair to fix it. Disable a network adapter and then use ipconfig and the Network Diagnostics tool to figure out why you cannot connect. A hands-on approach is crucial.

Focus your study on the new tools and concepts introduced in Windows Vista. You must understand the new BCD boot architecture and the purpose of the bcdedit.exe tool. The two most important new troubleshooting utilities to master are the Windows Recovery Environment (WinRE) for boot problems and the Reliability Monitor for diagnosing application and system stability issues.

Comprehensive Review of 70-621 Exam Objectives

In the final phase of your preparation for the 70-621 Exam, it is essential to return to the official Microsoft exam objectives. This document is the definitive guide to the skills that will be measured. The main objective domains typically include installing and upgrading, configuring network connectivity, configuring security features, maintaining and monitoring the system, and troubleshooting. Systematically review each objective and honestly assess your level of confidence.

This final pass-through will help you identify any remaining knowledge gaps. Perhaps you are very comfortable with configuring the firewall but less confident in using the bcdedit.exe command-line tool. Use this assessment to focus your last-minute study efforts where they will be most effective. This structured review ensures that you have covered the entire scope of the 70-621 Exam and are prepared for any topic that might appear.

Key "Vista-Specific" Concepts

A critical part of your final review for the 70-621 Exam should be to consolidate your knowledge of the features that were new and defining for Windows Vista. The exam will naturally focus on what was different from its predecessor, Windows XP. Your review list must include a deep understanding of User Account Control (UAC), as it was the most significant and impactful security change.

Other key Vista-specific features to review include the Aero graphical user interface and its hardware requirements, BitLocker Drive Encryption and its dependency on the TPM, the new two-way Windows Firewall with its network location profiles, the new BCD boot architecture, and the powerful new troubleshooting tools like the Windows Recovery Environment (WinRE) and the Reliability Monitor. A strong grasp of these "what's new" topics is essential for success.

Deconstructing Scenario-Based Questions

The questions on the 70-621 Exam are often presented as short scenarios. For example, a question might describe a user who is unable to connect to a wireless network or a situation where a specific application fails to start. You will then be asked to choose the most appropriate tool or course of action to resolve the issue. The key to answering these questions correctly is to carefully deconstruct the scenario.

Read the problem description carefully and identify the key symptoms and requirements. Eliminate any extraneous information. Then, mentally review the tools and technologies you have learned about and select the one that is best suited to the specific problem described. For instance, if the scenario describes a computer that will not start, you should immediately think of the tools available in the Windows Recovery Environment.

Time Management and Question Strategy

Effective time management is a critical skill for passing any certification exam, including the 70-621 Exam. You will have a limited amount of time to answer a set number of questions. Before you begin the exam, it is a good idea to calculate the average amount of time you can spend on each question. This will help you to maintain a steady pace throughout the test.

If you encounter a question that you find particularly difficult, do not spend too much time on it. It is often a better strategy to make your best educated guess, mark the question for review, and move on. This ensures that you have a chance to answer all the questions, especially the ones you are more confident about. You can then use any time you have left at the end of the exam to return to the questions you marked.

Common Pitfalls and Key Concepts

As you finalize your studies for the 70-621 Exam, be aware of a few common areas where candidates can get confused. A classic pitfall is mixing up share permissions and NTFS permissions. Remember that when accessing a resource over the network, the most restrictive of the two permission sets is what applies. Another key area is to have a clear understanding of the different UAC prompt behaviors for standard users versus administrators.

You should also pay close attention to which features are only available in specific editions of Windows Vista. For example, BitLocker, AppLocker, and support for joining a domain are not available in the Home editions. Knowing these key differences will help you to eliminate incorrect answer choices in scenario-based questions.

Final Exam Preparation Strategy

The single most important strategy for success on the 70-621 Exam is hands-on practice. This is a practical exam designed to test your ability to perform configuration and troubleshooting tasks. The best way to prepare is to build a virtual lab environment. Install Windows Vista in a virtual machine and work through all the exam objectives. Configure network settings, create firewall rules, enable BitLocker, and use the troubleshooting tools.

Supplement your hands-on work with official study materials, such as the Microsoft Press book for the 70-621 Exam, and use high-quality practice tests to gauge your readiness. A practice test will help you get used to the style of the questions and the pressure of the timed environment. The combination of theoretical knowledge and practical, hands-on skill is the key to passing.
