Lab Duration

It will take approximately 50 minutes to complete this lab.

Exercise 1 - Preparing the System for Database Availability Group

The concept of Database Availability Group (DAG) was introduced in one of the earlier versions of Exchange Server. A DAG can be created and the mailbox servers are added as members of DAG. The feature of Failover Clustering needs to be installed on the DAG members. Before creating the DAG, there are certain preparatory steps that need to be performed on the system to make it DAG compliant. The preparatory steps are as follows:

  • Add the Exchange Trusted Subsystem group in Active Directory to the local Administrator group on the server that will be the file share witness.
  • Install the File Server feature on the file share witness.
  • Install the Failover Clustering feature on the devices.
  • Turn off Windows Firewall.

In this exercise, you will learn how to prepare the system for a database availability group by performing the following tasks:

  • Task 1 - Add the Exchange Trusted Subsystem group to the local Administrator group.
  • Task 2 - Install the FileServer feature on the file share witness.
  • Task 3 - Install the Windows Cluster feature on the devices.
  • Task 4 - Turn off the Windows Firewall on the devices.

Learning Outcomes

After completing this exercise, you will be able to:

  • Add the Exchange Trusted Subsystem group to the local Administrator group.
  • Install the FileServer feature on the file share witness.
  • Install the Windows Cluster feature.
  • Turn off Windows Firewall.

Exercise 2 - Working with Mailbox Database Copies

As an administrator, you have performed the preparatory steps that are required before creating the DAG. You will create a new DAG. Once the DAG is created, member servers are added to it. The mailbox database copies are added to the DAG using the Exchange Management Shell or the Exchange Administrative Center. It is very important to monitor the health and status of the mailbox database copies. You may need to perform certain administrative tasks such as suspending, resuming, or removing mailbox database copies.

In this exercise, you will learn how to work with mailbox database copies by performing the following tasks:

  • Task 1 - Create a Database Availability Group (DAG).
  • Task 2 - Manage mailbox database copies.

Learning Outcomes

After completing this exercise, you will be able to:

  • Create a Database Availability Group (DAG).
  • Manage mailbox database copies.
