What operation is performed to transfer the RID master role?

To transfer the RID master role, the correct operation involves accessing the Server Manager and selecting Operations Masters. This process allows administrators to manage the Flexible Single Master Operations (FSMO) roles, which are critical in Active Directory environments. The RID (Relative Identifier) master is one of these roles, responsible for allocating RIDs to domain controllers so that they can create security principals such as user and group accounts.

By navigating to Operations Masters in Server Manager, you can directly access the console where the transfer of the RID master role can be performed. This action ensures that the management of RIDs is handled appropriately, particularly when transferring the role from one domain controller to another, which is essential for maintaining domain functionality and integrity.

The other options do not provide the necessary access or functionality to perform the transfer of the RID master role. Right-clicking on Domain Controllers does not lead to the role management capabilities needed, while using Active Directory Sites and Services is more aligned with viewing and managing domain topology and replication rather than directly transferring FSMO roles. The PDC tab is focused on the Primary Domain Controller Emulator role, which is separate from the RID master responsibilities.
