You have a failover cluster named Cluster1 that contains four nodes. All of the nodes run Windows
Server 2012 R2.
You need to schedule the installation of Windows updates on the cluster nodes.
Which tool should you use?
A.
the Add-CauClusterRole cmdlet
B.
the Wusa command
C.
the Wuauclt command
D.
the Invoke-CauScan cmdlet
Explanation:
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.Cluster-Aware Updating Overview

Detailed Description
The Add-CauClusterRole cmdlet adds the Cluster-Aware Updating (CAU) clustered role that provides the self-updating functionality to the specified cluster. 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.
