Final answer:
The Get-ADReplicationQueueOperation command is used in Active Directory environments to view the replication tasks that are pending in a domain controller's queue. It helps administrators diagnose replication issues and understand the controller's load. The correct option is A.
Step-by-step explanation:
The command that assists with obtaining pending information to be replicated in Active Directory environments is Get-ADReplicationQueueOperation. This PowerShell cmdlet is used by administrators to view the replication tasks that are currently queued in a domain controller. It's very useful for diagnosing replication issues and understanding the load and backlog on a particular controller.
When you execute the Get-ADReplicationQueueOperation command, you can expect to see details about operations that are waiting to be processed, such as the type of operation, priority, and the originating domain controller. This information can provide insights into potential replication delays or failures. An effective replication system is critical for the consistency of active directory data across different domain controllers in a network.
By contrast, the Get-ADReplicationConnection cmdlet is used for retrieving replication connections for a specified domain controller or a site. Meanwhile, Get-ADReplicationFailure cmdlet fetches data regarding the replication failures on a domain controller, helping administrators troubleshoot issues in the replication process.
It is important to regularly monitor Active Directory replication to ensure the health of the directory service, and the Get-ADReplicationQueueOperation cmdlet is an essential tool for this task.
