Answer is A
When the CAU clustered role has been added to a cluster, the failover cluster can update itself on the schedule that is specified by the user, without requiring an external computer to coordinate the cluster updating process.

Correct Answer: A
To enable self-updating mode, the CAU clustered role must also be added to the failover cluster. To do this by using the CAU UI, under Cluster Actions,
use the Configure Self- Updating Options action. Alternatively, run the Add-CauClusterRole Windows PowerShell cmdlet. Note: The process for
installing service packs and hotfixes on Windows Server 2012 differs from the process in earlier versions. In Windows Server 2012, you can use the
Cluster- Aware Updating (CAU) feature.
CAU automates the software-updating process on clustered servers while maintaining availability.
