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
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.
