You have a failover cluster named Cluster1 that contains four nodes. All of the nodes run Windows Server 2012
R2.
You need to force every node in Cluster1 to contact immediately the Windows Server Update Services (WSUS)
server on your network for updates.
Which tool should you use?
A.
The Add-CauClusterRole cmdlet
B.
The Wuauclt command
C.
The Wusa command
D.
The Invoke-CauScan cmdlet
Explanation:
The Add-CauClusterRole cmdlet adds the Cluster-Aware Updating (CAU) clustered role that provides the selfupdating 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.Incorrect:
Not B. The wuauclt utility allows you some control over the functioning of the Windows Update Agent. It is
updated as part of Windows Update.
The following are the command line for wuauclt.
Option Description
/a /ResetAuthorization
Initiates an asynchronous background search for applicable updates. If Automatic Updates is disabled, this
option has no effect.
/r /ReportNow
Sends all queued reporting events to the server asynchronously.
/? /h /help
Shows this help information.
Not D.
The Invoke-CauScan cmdlet performs a scan of cluster nodes for applicable updates and returns a list of the
initial set of updates that would be applied to each node in a specified cluster.
Note: The Invoke-CauRun cmdlet performs a scan of cluster nodes for applicable updates and installs those
updates via an Updating Run on the specified cluster.

Confusing, pretty sure this must be D.

There is already answer to this question – https://www.briefmenow.org/microsoft/which-tool-should-you-use-1034/
Question states “CONTACT immediately WSUS for updates” (not Install)
Installation of the CAU role is NOT required as it is installed as part of the FoC role.
Quoting from:
https://technet.microsoft.com/en-us/library/hh831367(v=ws.11).aspx
“A CAU installation is seamlessly integrated into the Failover Clustering feature.
CAU is installed as follows:
-When Failover Clustering is installed on a cluster node, the CAU Windows Management
Instrumentation (WMI) provider is automatically installed (…)
(you can read all 3 dots, or even better the whole article)
To summarise
-CAU is already installed
-Just “contact” (No installation) is needed

Question states : contact IMMEDIATELY -StartDate !
Add-CauClusterRole -ClusterName Cluster1 -Force -CauPluginName Microsoft.WindowsUpdatePlugin (Installs cluster updates directly from Windows Update or Microsoft Update, or from an on-premises WSUS server) -StartDate “4/21/2014 3:00:00 AM” (Specifies the earliest date on which the Updating Run can be triggered)
