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- AwareUpdating (CAU) feature. CAU automates the software-updating process on clustered servers
while maintaining availability.
You can configure the update schedule when you install the CAU role.
Add-CauClusterRole -ClusterName CONTOSO-FC1 -DaysOfWeek Tuesday,Saturday -WeeksOfMonth 2,4 -MaxFailedNodes 2 -MaxRetriesPerNode 2 -PostUpdateScript \\CONTOSOFileShare\scripts\verifyupdatesinstalled.ps1 -RequireAllNodesOnline –EnableFirewallRules -Force
Wusa is for manually dealing with individual updates.
Wuauclt can be used with /updatenow, but that’s not scheduled.
Invoke-causcan only lists updates need.
Invoke-caurun will scan and apply updates, but it’s not on here.
