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 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.
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.Add-CauClusterRole

If you adds the Cluster-Aware Updating (CAU) clustered role you provide self-updating functionality to a specified cluster.
After that, using the Invoke-CauScan will 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.
You can tell the cluster then to update. But this is NOT asked here. They just want to “Contact WSUS for updates”…

i would go with A, because with CAU you can start “immediately “

There is answers to your comment in previous dumps…
A suggestion : Better to read previous dumps, read articles and think about comments before sending notes here..

I hate question like that. We will never know the right answer. according to all past dumps there were fair argument with both A and D. A will make more sense because the question ask to “force every node in Cluster1” so therefore “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”

The only reason I’m going with D is because it states “Immediately.” If it weren’t for that, I’d say both A and D are completely viable answers.

Hi Nate
do you mean A?

Collegues,
As I have read it, Add-CauClusterRole only INSTALLS and CONFIGURES the role.
I DOES NOT start anything and there is no IMMEDIATELY option.
If you want the Cluster to check for update NOW, you have CAU already installed and should run Invoke-CauScan (scans and returns a list of updates)or Invoke-CauRun ( which scans and installs).
