Acing the MB2-866 Exam: A Guide to Foundational Concepts and Pre-Installation Planning

The Microsoft MB2-866 Exam, "Microsoft Dynamics CRM 2011 Installation and Deployment," was a specialized certification test designed for IT professionals responsible for the technical implementation of the Dynamics CRM platform. The primary audience for this exam included deployment consultants, system administrators, and infrastructure engineers. Passing the MB2-866 Exam validated a candidate's competence in planning, installing, configuring, and maintaining a robust and scalable on-premise Dynamics CRM 2011 environment. It was a testament to their ability to build the very foundation upon which a successful CRM solution operates.

Unlike other exams in the Dynamics CRM 2011 track that focused on customization or application usage, the MB2-866 Exam was purely technical and infrastructure-oriented. It covered the entire deployment lifecycle, from initial hardware and software planning to the installation of server roles, configuration of email integration, and deployment of the client for Outlook. The exam tested a deep understanding of the product's architecture and its dependencies on other Microsoft technologies like Windows Server, Active Directory, SQL Server, and IIS.

For any technical professional aiming to specialize in the infrastructure side of Dynamics CRM, passing the MB2-866 Exam was a critical career milestone. It certified a level of expertise that was in high demand, as a correctly planned and executed deployment is essential for the performance, scalability, and reliability of the entire CRM system. This exam was a rigorous assessment of these vital and foundational skills.

Understanding the Microsoft Dynamics CRM 2011 Architecture

A core prerequisite for the MB2-866 Exam was a solid understanding of the multi-tiered architecture of Microsoft Dynamics CRM 2011. The platform is not a single application but rather a collection of interconnected services and components that work together. At the heart of the system is the Microsoft SQL Server database, which stores all the application data, metadata, and configuration information. The performance and health of the SQL Server are paramount.

The application logic and business rules are executed on the Application Server. This server runs the core Dynamics CRM services, including the asynchronous processing service for background jobs and workflows. The presentation layer is handled by the Web Server, which runs on Microsoft Internet Information Services (IIS). The IIS server hosts the CRM web application that users access through their web browsers.

For reporting, Dynamics CRM 2011 integrates tightly with SQL Server Reporting Services (SSRS). All the standard and custom reports are rendered by the SSRS engine. Understanding how these different components—SQL Server, the CRM application services, IIS, and SSRS—interact and depend on each other was a fundamental concept for any question on the MB2-866 Exam related to design or troubleshooting.

Differentiating Server Roles

For scalability and performance in larger deployments, the various functions of the Dynamics CRM server can be split across multiple physical or virtual machines. The MB2-866 Exam required a clear understanding of the different server roles that could be assigned during installation. This knowledge is crucial for designing a deployment topology that can support a large number of users or specific high-availability requirements.

A "Full Server" installation, which is common for smaller deployments, installs all the server roles onto a single machine. For larger environments, you could separate the roles. A "Front End Server" role would typically run the web server components (IIS) and would be responsible for handling user requests. A "Back End Server" role would run the asynchronous processing service and other background tasks. A "Deployment Administration Server" would host the Deployment Manager tool and handle administrative tasks.

By separating these roles, an organization could scale out its deployment. For example, you could have a farm of multiple load-balanced Front End Servers to handle a large number of concurrent web users, while having dedicated Back End Servers to process workflows and other background jobs without impacting the user interface performance.

Planning the Infrastructure: Hardware and Software Requirements

A significant portion of the MB2-866 Exam was dedicated to the critical pre-installation planning phase. Before you can even begin the installation, you must design an infrastructure that can support the intended workload. This involves careful consideration of both the hardware and software requirements. The exam would often present scenarios with a specific number of users and would expect you to choose the appropriate hardware specifications.

Hardware planning involves sizing the CPU, memory, and disk space for each of the servers in your deployment (CRM Server, SQL Server, etc.). The requirements vary significantly based on the number of users, the complexity of the customizations, and the volume of transactions. For example, a deployment for 1,000 users would require substantially more powerful servers than a deployment for 50 users.

Equally important is ensuring that all the software prerequisites are met. The MB2-866 Exam required detailed knowledge of the supported software versions. This included the specific editions and service pack levels of Windows Server, Microsoft SQL Server, and the required roles and features that must be installed, such as specific components of IIS and the .NET Framework. A failure to meet any of these prerequisites would cause the installation to fail.

Planning for Active Directory Integration

Microsoft Dynamics CRM 2011 is a product that is deeply integrated with and dependent on Active Directory. The MB2-866 Exam required a thorough understanding of this relationship. Active Directory is used for two primary purposes: to authenticate users who are accessing the CRM system and to provide the organizational structure for managing the CRM deployment.

Before installation, the Active Directory environment must be prepared. This includes ensuring that the domain and forest are at a supported functional level. More importantly, it involves creating a dedicated Organizational Unit (OU) in Active Directory to hold all the security groups that the CRM installation process will create. This is a critical best practice that isolates the CRM-related objects and simplifies permission management.

The CRM installation creates several security groups that are used to control access to the CRM services and databases. An administrator must be a member of the appropriate groups to perform the installation. Understanding the names and purpose of these security groups and the need for a dedicated OU was a fundamental piece of planning knowledge for the MB2-866 Exam.

The Microsoft Dynamics CRM Security Model

While the in-depth customization of the security model was covered in other exams, the MB2-866 Exam required a foundational understanding of its core components, as they are established during the initial deployment. The security model in Dynamics CRM is hierarchical and is based on the concept of Business Units. A Business Unit typically represents a division or a department within a company. The entire organizational structure is built as a tree of Business Units.

Access to the data is then controlled by "Security Roles." A security role is a collection of privileges that defines what actions a user can perform (e.g., create, read, write, delete) on different types of records (entities). For example, a "Salesperson" security role might grant a user the ability to create and edit their own opportunities but only to read the opportunities of others in their business unit.

Finally, a "User" is created in CRM for each person who needs to access the system. Each user must be assigned to one Business Unit and must be given at least one Security Role. This combination of the user's Business Unit and their assigned roles determines exactly what they can see and do within the CRM application.

Understanding Deployment Models: On-Premise vs. Hosted (IFD)

The MB2-866 Exam was focused on the on-premise version of Dynamics CRM, but it required a clear understanding of the different ways this on-premise deployment could be configured for user access. The standard deployment model is a purely internal one, where the CRM website is only accessible to users who are connected to the company's internal corporate network.

However, many organizations have a need to provide access to their CRM system for remote users, such as salespeople on the road, who are not connected to the corporate network via a VPN. To support this requirement, Dynamics CRM 2011 offered a special deployment model called an Internet-Facing Deployment, or IFD. The configuration of IFD was a major topic for the exam.

An IFD deployment exposes the CRM website securely to the internet. It uses a claims-based authentication model, relying on Active Directory Federation Services (AD FS) to authenticate the external users. This allows a user to access the full CRM application through their web browser or the Outlook client from anywhere with an internet connection, without needing a VPN. The ability to design for and configure IFD was a key skill.

Preparing the Environment for Installation

Before running the Microsoft Dynamics CRM 2011 setup wizard, the server and Active Directory environment must be meticulously prepared. The MB2-866 Exam emphasized the importance of this pre-installation checklist, as a failure to complete these steps is a common cause of installation failure. A critical part of this preparation is the creation of the necessary service accounts and security groups in Active Directory.

The CRM installation requires at least one service account that will be used to run the core CRM services. It is a best practice to use a dedicated, low-privilege domain user account for this purpose, not a highly privileged administrator account. You also need to create a dedicated Organizational Unit (OU) within Active Directory. This OU will be used to store all the security groups that the CRM setup process will create automatically.

The user who is performing the installation must have the appropriate permissions. This includes being a local administrator on the CRM server and having the rights to create security groups within the designated OU in Active Directory. Ensuring all these prerequisites are met before starting the installation is a key step for a smooth deployment and a core competency for the MB2-866 Exam.

Installing Microsoft SQL Server for CRM 2011

Microsoft Dynamics CRM 2011 relies entirely on Microsoft SQL Server for its database services. The proper installation and configuration of SQL Server is a critical prerequisite, and its specific requirements were a key topic for the MB2-866 Exam. You could not simply perform a default installation of SQL Server; several specific settings had to be configured correctly for the CRM installation to succeed.

First, you had to ensure that you were using a supported version and edition of SQL Server. The CRM installer would check this. A crucial setting during the SQL Server installation is the collation. The collation determines the sorting rules and case sensitivity of the database. The CRM installation required a case-insensitive collation.

You also had to ensure that the necessary SQL Server components were installed. This included the core Database Engine, the Full-Text Search feature, and the SQL Server Reporting Services (SSRS) for report rendering. Finally, the network protocols for SQL Server, such as TCP/IP, needed to be enabled, and the Windows Firewall had to be configured to allow communication between the CRM server and the SQL Server.

Installing Microsoft Dynamics CRM Server

Once all the prerequisites were in place, the next step was to run the main Microsoft Dynamics CRM Server installation wizard. The MB2-866 Exam would expect you to be intimately familiar with the steps and the choices presented in this wizard. The installation process begins with the setup wizard checking for any missing software components and offering to install them automatically.

A key part of the setup is the Environmental Diagnostics Wizard. This tool performs a comprehensive series of checks on the server to ensure that all the hardware and software prerequisites have been met. It will verify everything from the Active Directory functional level to the specific configuration settings in IIS. If any checks fail, the wizard provides a detailed report of the issue that must be resolved before the installation can continue.

During the installation, you must specify the service account that will be used to run the CRM services, the SQL Server that will host the databases, and the OU in Active Directory where the security groups will be created. You also choose the installation path and, if this is the first server in the deployment, you will create the initial default organization.

Understanding the Installation Log Files

Even with careful preparation, a Microsoft Dynamics CRM installation can sometimes fail. When this happens, the most important tool for diagnosing the problem is the set of detailed log files that the setup wizard creates. The MB2-866 Exam required an administrator to know where to find these log files and how to interpret them to find the root cause of an installation error.

The installation log files are typically located in the user's Application Data folder. The main log file provides a chronological record of every action that the setup wizard performed. When an error occurs, the setup will typically fail on a specific step. By reviewing the log file, you can pinpoint the exact action that failed and see the detailed error message that was returned by the system.

For example, the log file might show that the installation failed while trying to create a security group in Active Directory, which would point to a permissions issue for the installing user. Or, it might show an error when trying to connect to the SQL Server, which would indicate a network connectivity or authentication problem. The ability to read and understand these log files is an essential troubleshooting skill.

Post-Installation Tasks and Verification

Successfully completing the server installation wizard is a major milestone, but it is not the final step. The MB2-866 Exam covered the key post-installation tasks that must be performed to complete the deployment and to verify that it is functioning correctly. One of the first tasks is to create the primary organization that the business will use, if this was not done during the installation. This is done using the Deployment Manager tool.

Once the organization is created, the most important verification step is to try to access the CRM web application using a web browser. By navigating to the CRM server's URL, you should be presented with the CRM login screen. After logging in, you should be able to see the main CRM interface, which confirms that the core web application is running correctly.

Another critical post-installation step is to apply the latest Update Rollup for CRM 2011. These update rollups contain important bug fixes and performance improvements and should always be applied to a new deployment before it is put into production. The final step is to configure the various integrations, such as the Email Router and the Reporting Extensions.

Installing the Microsoft Dynamics CRM Reporting Extensions

For the reporting functionality in Microsoft Dynamics CRM 2011 to work, a separate component called the Reporting Extensions must be installed. The installation of this component was a key topic for the MB2-866 Exam. The Reporting Extensions act as a data connector that allows the SQL Server Reporting Services (SSRS) server to communicate with the CRM databases and to understand the CRM security model.

The Reporting Extensions must be installed on the server that is running SQL Server Reporting Services. The installation is performed using a separate setup wizard that is included on the CRM installation media. During the installation, you must specify the name of the SQL Server instance that SSRS is running on and the name of the CRM Application Server.

Without this component, users would not be able to run any of the standard or custom reports within the CRM application. The report would fail with an error indicating that it could not connect to the data source. Therefore, the installation of the Reporting Extensions is not an optional step; it is a mandatory part of any on-premise CRM 2011 deployment.

Installing the Microsoft Dynamics CRM Email Router

Microsoft Dynamics CRM 2011 provides two options for integrating with an email system like Microsoft Exchange. The primary client-side option is the CRM Client for Outlook. The server-side option, and a major topic for the MB2-866 Exam, is the Microsoft Dynamics CRM Email Router. The Email Router is a separate software component that is installed on a dedicated server. Its purpose is to provide server-side synchronization of incoming and outgoing emails for CRM users.

The Email Router works by polling the user's mailbox on the email server (e.g., Exchange) for incoming messages. It can then track these messages in CRM based on specific correlation rules. For outgoing email, it can poll the CRM system for email messages that need to be sent and can then forward them to the email server for delivery.

The installation of the Email Router is done through its own setup wizard. After the installation, the main task is to use the Email Router Configuration Manager to create the incoming and outgoing profiles that define how the router will connect to the email server and to the CRM deployment. The Email Router provides a centralized way to manage email integration without needing to install any software on the end-user's machine.

A Closer Look at the Deployment Manager

The primary administrative tool for managing the high-level aspects of a Microsoft Dynamics CRM 2011 deployment is the Deployment Manager. This is an MMC snap-in that is installed on the CRM server. A thorough understanding of its capabilities was essential for the MB2-866 Exam. The Deployment Manager is the tool you use to perform tasks that affect the entire deployment, rather than just a single organization.

From the Deployment Manager, an administrator can create new organizations, disable or delete existing organizations, and import organizations from another deployment. It is also the tool used to manage the servers in the deployment. You can see all the servers that are part of the CRM farm, view their roles, and add or remove servers.

Other key functions of the Deployment Manager include managing the web addresses for the application, configuring claims-based authentication and the Internet-Facing Deployment (IFD), and managing the data encryption key for the deployment. It is the central command center for the entire CRM infrastructure, and the MB2-866 Exam would test your knowledge of how to use it for these critical administrative functions.

Using the Deployment Manager for High-Level Administration

The Deployment Manager is the cornerstone of administrative control for a Microsoft Dynamics CRM 2011 on-premise installation. A key area of focus for the MB2-866 Exam was understanding the scope and application of this vital tool. Unlike the web-based settings area which manages a single organization's customizations, the Deployment Manager operates at a higher level, overseeing all organizations and servers within a single CRM deployment.

Day-to-day use of this tool includes a range of critical functions. Administrators use it to manage the lifecycle of organizations, including creation, import, disabling, and deletion. It also provides a centralized view of all servers participating in the CRM farm, allowing an administrator to view or change server roles. For instance, you could add a new Front End Server to a deployment to scale out the web traffic capacity.

Furthermore, the Deployment Manager is the exclusive tool for configuring deployment-wide settings. This includes managing web addresses, setting up claims-based authentication for an Internet-Facing Deployment (IFD), and managing the vital data encryption key. Proficiency in navigating and utilizing the Deployment Manager was a non-negotiable skill for any candidate taking the MB2-866 Exam.

Managing Organizations

Microsoft Dynamics CRM 2011 supports a multi-tenant architecture, which means that a single CRM deployment can host multiple, separate organizations. Each organization has its own isolated database and represents a distinct business entity. The management of these organizations was a key administrative topic for the MB2-866 Exam. This capability is particularly useful for partners who want to host CRM for multiple different customers on a single set of servers.

The Deployment Manager is the tool used to perform all the lifecycle operations for an organization. An administrator can use the "New Organization" wizard to create a brand-new, empty organization. The wizard will create a new SQL database for the organization and provision it with the default CRM schema and data.

A more advanced and powerful feature is the ability to import an existing organization. The "Import Organization" wizard allows an administrator to take a backup of an organization's database from another CRM deployment (for example, a test environment) and to import it into the current deployment. This is the standard method for migrating organizations between different CRM environments and was a key process to understand for the MB2-866 Exam.

Configuring Server-Side Email Integration

The Microsoft Dynamics CRM Email Router is the primary component for server-side email processing, and its detailed configuration was a major topic for the MB2-866 Exam. After installing the Email Router software, all the configuration is done through the Email Router Configuration Manager tool. This tool allows an administrator to define how the Email Router will connect to the CRM deployment and to the email server, such as Microsoft Exchange.

The configuration is based on profiles. An administrator must create an "Outgoing Profile" that specifies the SMTP server information that the router will use to send emails on behalf of CRM users. For processing incoming email, you would create an "Incoming Profile." This profile defines how the router will connect to the user's mailboxes to poll for new messages. It could be configured to use Exchange Web Services or POP3.

The Email Router can be set up to either forward emails to a special queue for tracking or to synchronize emails directly with the user's activities in CRM. Understanding the difference between these methods and the steps required to create and test the various profiles was an essential practical skill for any administrator and a core competency for the MB2-866 Exam.

Configuring an Internet-Facing Deployment (IFD)

Providing secure access to CRM for external users without a VPN is achieved through an Internet-Facing Deployment (IFD). The complex, multi-step process of configuring IFD was one of the most advanced and important topics on the MB2-866 Exam. IFD relies on claims-based authentication, which delegates the task of authenticating the user to a trusted identity provider, which in this case is Active Directory Federation Services (AD FS) 2.0.

The entire IFD configuration process is initiated from the Deployment Manager using the "Configure Internet-Facing Deployment" wizard. This wizard requires the administrator to specify the external domain names that will be used to access the CRM web application. For example, you might specify that the application will be accessible at an external URL.

Once the wizard is complete, the next and more complex part of the process is to configure the trust relationships between the CRM deployment and the AD FS server. This involves running a series of PowerShell commands to set up CRM as a "relying party" in AD FS. This tells the AD FS server that it is trusted to issue authentication tokens for the CRM application.

Installing and Configuring AD FS 2.0 for IFD

Active Directory Federation Services (AD FS) 2.0 is a mandatory prerequisite for an Internet-Facing Deployment of CRM 2011. The MB2-866 Exam would expect a candidate to have a solid conceptual understanding of the role of AD FS and the high-level steps for its configuration. AD FS is a Windows Server role that provides a security token service (STS). Its job is to authenticate users against Active Directory and then to issue them a security token containing "claims" about their identity.

The installation of AD FS is done through the Server Manager. After the role is installed, the administrator must use the AD FS Management console to configure the federation server. This includes tasks like specifying the service account, creating the necessary databases, and configuring a certificate for securing the token signing process.

For an IFD configuration, there are two key trusts that must be established. A "Claims Provider Trust" is configured to tell AD FS that it should trust the on-premise Active Directory as the source of user authentication. A "Relying Party Trust" is configured for the CRM application. This trust defines the rules for how AD FS will issue tokens for CRM, including which claims will be included in the token.

Upgrading and Redeploying a CRM Deployment

Many real-world projects involve upgrading from an older version of Microsoft Dynamics CRM. The MB2-866 Exam covered the supported methods for migrating a deployment from a previous version, such as CRM 4.0, to CRM 2011. It is important to note that a direct, in-place upgrade of the CRM 4.0 server was not the recommended approach.

The supported and preferred method for upgrading was a migration-based approach using the Deployment Manager. This involved building a brand-new, clean CRM 2011 deployment on new servers. Once this new environment was set up and verified, the next step was to take a full backup of the organization's database from the old CRM 4.0 SQL Server.

This CRM 4.0 database backup would then be restored to the new SQL Server that was part of the CRM 2011 deployment. Finally, the administrator would use the "Import Organization" wizard in the CRM 2011 Deployment Manager to point to this restored database. The import wizard would then perform the upgrade of the database schema and the data to the CRM 2011 format, effectively migrating the organization into the new deployment. This process was also used for redeploying an organization.

Introduction to the CRM 2011 Client for Outlook

For many users, the primary interface for interacting with Microsoft Dynamics CRM 2011 was not the web browser, but a tightly integrated client that runs within Microsoft Outlook. The features and deployment of this client were a major topic for the MB2-866 Exam. The Microsoft Dynamics CRM 2011 Client for Outlook is a powerful add-in that brings the full functionality of CRM directly into the familiar Outlook interface.

This integration provides several key benefits for user adoption and productivity. Users can access all their CRM records, such as accounts, contacts, and opportunities, directly from a navigation pane within Outlook. They can track emails, appointments, and tasks against CRM records with a single click. They can also work with CRM data even when they are not connected to the network.

A crucial feature of the Client for Outlook is its offline capability. When this is configured, the client will create a local copy of a subset of the CRM data on the user's laptop using SQL Server Express. The user can then view and modify this data while they are on a plane or at a customer site with no internet access. When they reconnect, the client will automatically synchronize all their changes back to the main CRM server.

Planning a Client for Outlook Deployment

Before deploying the Microsoft Dynamics CRM Client for Outlook to a large number of users, careful planning is required. The MB2-866 Exam required an administrator to be aware of the prerequisites and the different deployment methods. The planning phase starts with verifying that the client machines meet the minimum hardware and software requirements. This includes having a supported version of Windows, Microsoft Office, and the .NET Framework.

An administrator must also decide on the deployment method. For a small number of users, a manual installation on each machine might be feasible. For a large enterprise deployment with hundreds or thousands of users, a manual installation is not practical. In these cases, an automated deployment method is necessary.

The two primary methods for automated deployment were using a command-line script for a silent installation or using a software distribution system like Group Policy or System Center Configuration Manager (SCCM). The choice of method would depend on the existing software management infrastructure in the organization. The MB2-866 Exam would often present scenarios that required you to choose the most appropriate deployment method.

Installing the CRM 2011 Client for Outlook

The manual installation process for the CRM Client for Outlook was a practical skill that an administrator needed to know for the MB2-866 Exam, as it is often used for initial testing and for troubleshooting. The installation is performed by running a setup wizard from the installation media or a downloaded file. The wizard guides the user through the process of installing the necessary files and the Outlook add-in.

After the installation of the software is complete, the next and equally important step is to run the Configuration Wizard. The Configuration Wizard is used to connect the newly installed client to a specific CRM organization. The user must provide the URL of the CRM server. The wizard will then connect to the server and present the user with a list of the organizations that they are a member of.

The user selects the organization they want to connect to, and the wizard completes the configuration. Once this is done, the next time the user opens Microsoft Outlook, they will see the new CRM navigation panes and toolbars, and the client will begin its initial synchronization of data from the server.

Deploying the Client for Outlook via Command Line or Group Policy

For large-scale deployments, the manual installation process is too time-consuming. The MB2-866 Exam required knowledge of the methods for automating the installation of the CRM Client for Outlook. The primary mechanism for this was to use a command-line installation. The setup executable for the client supported a range of command-line switches that allowed for a "silent" or unattended installation.

An administrator would create an XML configuration file that contained all the information that a user would normally enter during the interactive setup, such as the CRM server URL. They could then run the setup executable from a script with a /Q switch for a quiet installation and a /config switch to point to the XML file. This would install and configure the client without requiring any user interaction.

This command-line installation could then be packaged and deployed using a software distribution system. A common method in a Windows environment was to use Group Policy Software Installation. An administrator could create a Group Policy Object (GPO) that would automatically run the silent installation script on all the computers in a specific Organizational Unit, providing a fully automated rollout of the client to an entire department.

Configuring Offline Synchronization

One of the most powerful features of the CRM Client for Outlook, and a key configuration topic for the MB2-866 Exam, is its ability to work offline. When a user chooses to go offline, the client synchronizes a subset of the CRM data to a local SQL Server Express database on their laptop. The administrator has a great deal of control over what data gets synchronized.

This is managed through the "Offline Synchronization Filters" that are configured within the CRM web application. From the options menu, a user can view and edit their offline filters. These filters allow the user to specify which records they want to take offline. For example, a salesperson might configure their filters to only take their own accounts, their own active opportunities, and their own contacts offline.

This is crucial for managing the size of the local database and for reducing the synchronization time. An administrator can also create and manage these filters centrally using the security role customization interface. The ability to plan for and configure these offline filters to meet the needs of a mobile sales force was an important administrative skill.

Troubleshooting Client for Outlook Issues

When deploying and managing the CRM Client for Outlook, administrators will inevitably encounter issues that need to be resolved. The MB2-866 Exam would expect a candidate to be familiar with the common types of client-side problems and the tools for troubleshooting them. Common issues include failures during the initial configuration, problems with data synchronization, or conflicts with other Outlook add-ins.

When a user reports a problem, the first place to look for information is the client-side log files. The CRM Client for Outlook creates detailed trace log files that record all its activities. These log files can be enabled and viewed through a diagnostic tool that is installed with the client. The logs will typically contain specific error messages that can point to the root cause of the problem, whether it is a network connectivity issue or a permission problem.

Another common issue is synchronization failures. A user might report that the changes they made while offline are not appearing on the server. The Synchronization dialog within Outlook provides a view of the synchronization status and any errors that have occurred. Understanding how to use these diagnostic tools to isolate and resolve client-side problems was a key practical skill for the MB2-866 Exam.

High Availability and Disaster Recovery for CRM

For most organizations, the CRM system is a mission-critical application. Therefore, designing an infrastructure that is resilient to failures is a crucial part of the deployment plan. The MB2-866 Exam required a solid understanding of the high availability and disaster recovery options for a Microsoft Dynamics CRM 2011 deployment. This involves building redundancy at each tier of the CRM architecture.

For the web tier, high availability is typically achieved by deploying multiple Front End Servers in a load-balanced farm. Microsoft's Network Load Balancing (NLB) feature in Windows Server was the standard technology used for this. NLB would distribute the incoming web traffic across all the servers in the farm and would automatically redirect traffic away from any server that failed.

For the critical database tier, the premier high availability solution was to use SQL Server Failover Clustering. This involves setting up a cluster of two or more SQL servers that are connected to a shared storage system. The CRM databases would run on the active node of the cluster. If that node failed, the SQL Server services would automatically fail over to a passive node, with minimal downtime.

Backup and Restore Strategy for CRM 2011

A comprehensive and regularly tested backup strategy is the absolute foundation of any disaster recovery plan. The MB2-866 Exam placed a strong emphasis on the correct procedures for backing up and restoring a Microsoft Dynamics CRM 2011 environment. It is crucial to understand that a CRM deployment consists of multiple components that must all be backed up in a consistent manner.

The most critical components to back up are the SQL Server databases. This includes the organization's main database (which has a name like OrganizationName_MSCRM) and, just as importantly, the deployment's configuration database, which is always named MSCRM_CONFIG. Standard SQL Server maintenance plans should be used to perform regular full and transaction log backups of these databases.

In addition to the databases, it is also important to back up the data encryption key for the deployment. This key is managed through the Deployment Manager and is essential for being able to access any encrypted data after a restore. The supported method for restoring a failed CRM deployment involves building a new set of CRM servers and then using the Deployment Manager's "Import Organization" wizard to restore the organization database onto the new farm.

Monitoring a CRM Deployment

Proactive monitoring is essential for maintaining the health and performance of a CRM deployment. The MB2-866 Exam required an administrator to be familiar with the key tools and metrics for monitoring the various components of the CRM infrastructure. The primary tool for this in a Windows environment is the Performance Monitor (PerfMon).

An administrator should set up a monitoring baseline to track key performance counters over time. For the CRM web server, important counters to watch include the ASP.NET performance counters, such as "Requests Queued" and "Request Execution Time," as well as the general server health metrics for CPU and memory utilization. For the SQL Server, you should monitor key counters for disk I/O, memory usage (like buffer cache hit ratio), and CPU.

For more detailed diagnostics, Dynamics CRM includes a built-in tracing tool. Tracing can be enabled on the CRM server to generate very detailed log files of all the application's activities. While this can have a performance impact and should not be left on permanently in a production environment, it is an invaluable tool for troubleshooting specific, hard-to-diagnose application errors.

Managing Updates and Service Packs

Microsoft regularly releases updates for its products to provide bug fixes, security patches, and new features. The MB2-866 Exam required an administrator to understand the process for managing these updates for a Dynamics CRM 2011 deployment. The updates for CRM are delivered as "Update Rollups." It is a best practice to keep the CRM deployment, including both the servers and the clients, up to date with the latest supported Update Rollup.

The process for applying an Update Rollup involves several steps. First, and most importantly, the update should always be tested in a non-production, development or staging environment before it is ever applied to the live production system. This is crucial to ensure that the update does not have any negative impact on any custom code or configurations.

Once the update has been tested, it must be installed on all the servers in the CRM farm. The update needs to be applied to the CRM servers, the Email Router, and the Reporting Extensions. After the server-side update is complete, the updated client software must then be deployed to all the user machines that are running the CRM Client for Outlook.

Troubleshooting Server-Side Issues

Even in a well-maintained deployment, server-side issues can occur. The MB2-866 Exam would expect an administrator to have a systematic approach to troubleshooting these problems. Common server-side issues include failures of the asynchronous processing service, which can cause workflows and other background jobs to stop running, problems with report rendering, or issues with the Email Router.

The first and most important source of information for troubleshooting any server-side problem is the Windows Event Viewer on the CRM server. The CRM platform writes detailed informational, warning, and error messages to the Application log. These event log entries often contain a specific error code or a message that can point directly to the root cause of the problem.

For more complex issues, the next step is to enable and analyze the CRM platform trace logs. These logs provide a much more granular, developer-level view of the application's execution. By analyzing the sequence of events in the trace log leading up to an error, an administrator or a support professional can often diagnose very complex problems that are not apparent in the standard event logs.

Mastering the MB2-866 Exam Format

To be successful on the MB2-866 Exam, it was essential to be prepared for the classic Microsoft certification exam format. The exam was a computer-based test consisting of a series of multiple-choice questions that had to be answered within a set time limit. The questions were designed to assess not just your ability to recall facts, but your ability to apply your knowledge to solve practical, real-world deployment and administration problems.

The questions were often scenario-based. A typical question would describe a customer's environment, a specific business requirement, or a technical problem. You would then be presented with several possible solutions and would have to choose the one that was the most correct, efficient, or followed the recommended best practices.

This style of questioning meant that hands-on experience was absolutely critical for success. Simply reading the product documentation was not enough. You needed to have actually performed the tasks, such as installing the server, configuring IFD, or troubleshooting a failed client installation, to be able to confidently answer the detailed, scenario-based questions that were the hallmark of the MB2-866 Exam.
