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:
A) Adds the Cluster-Aware Updating (CAU) clustered role that provides the self-updating
functionality to the specified cluster.
B) the wuauclt utility allows you some control over the functioning of the Windows Update
Agent
C) The Wusa.exe file is in the %windir%\System32 folder. The Windows Update Standalone
Installer uses the Windows Update Agent API to install update packages. Update packages
have an .msu file name extension.
The .msu file name extension is associated with the Windows Update Standalone Installer.
D) 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.

Thanks Sam!, guys can anyone of you have the corrections from Rod’s dump in examcollection?
ditto to what benz said
dittto
Ditto (Japanese: メタモン Metamon) is a Normal-type Pokémon.
It is not known to evolve into or from any other Pokémon.
It can breed with any Pokémon other than the Pokémon in the Undiscovered group and itself, including some genderless Pokémon, to produce Eggs of the other’s species
But yes I agree with D lol
Not sure I agree. Why are we all assuming the cluster has CAU installed? Not stated.
The CAU role allows the cluster to update itself automatically. It is not required for the invoke-causcan command to work.
I created a 1 node cluster, did not configure anything else (so CAU was not configured/installed after creating it)
Ran invoke-causcan -clustername cluster01 and it came back with a list of updates for the node that had been added to the cluster.
So the answer must be D
Not D. The invoke-CauScan cmdlet scans cluster nodes for applicable updates and returns a list of the initial set of updates that would applied to each node in a specified cluster.
The Invoke-CauRun cmdlet scans cluster nodes for applicable updates and installs those updates via an Updating Run on the specified cluster.
The answer must be A. Nodes must contact de WSUS.
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.

I Agrreeeeeeeed
But it’s not asking us to download anything, it’s just asking us to contact the WSUS server. Which is what the invoke command does as stated below:
-CauPluginName
Specifies one or more plug-ins to use when performing scans. You can specify multiple values separated with commas. The default is the Microsoft.WindowsUpdatePlugin plug-in. This plug-in coordinates the Windows Update Agent software resident on each cluster node, the same software that is used when updates are downloaded from Windows Update or Microsoft Update, or from a Windows Server Update Services (WSUS) server. For more information about how plug-ins work with CAU, see the content about Cluster-Aware Updating plug-ins.
I bet I can bent the answer…
By the way, where is Hassan?
Somebody please tell the answer?
😀
haha
🙂 you made me happy Hassan , in the middle of confusion at least someone bright up my day
I kill myself!
Answer is A – 100%.
Question is to schedule the updates not list the applicable updates
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.
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. Generating the list might take a few minutes.
The answer should be D.
The question was not worded well, contacting the WSUS straight away for updates was a little vague.
It could mean getting updates from the WSUS to install them, or simply just retrieving the list of applicable updates.
A: Add-CauClusterRole adds the CAU object in the AD to allow the cluster to run CAU for the nodes in the cluster. It does not trigger a run, hence the servers will not contact the WSUS at all until you trigger a run. Therefore it t does not satisfy the question’s condition of forcing all the nodes to contact the WSUS.
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)
Correct Answer: D
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.
You said D,but then gave an explenation as to why A is correct,make up your mind buddy!

Answer is A Add-CauClusterRole.
In a CAU senario there is 2 choices:
1- Manually update each node of the cluster this is called Manual or remote updating mode. this does not require the Add-CauClusterRole because u do not need to integrate the CAU role with the cluster. U simply right click on the node from server manager and click update cluster.
2- Self-updating method is when u need to update or let all the nodes in a cluster contact WSUS or windows updates automatically (prefered method is the wsus of course).
In this case u need to add the CAU role to the cluster this can be done using the GUI inside of the cluster (choose cluster aware updating) or from powershell using the Add-CauClusterRole.
So getting back to the requirements of this question which is “You need to force every node in Cluster1 to contact immediately the Windows Server
Update Services (WSUS) server on your network for updates” u must select A because again it says EVERY NODE not one node at a time.
cheers
Wrong.
“D) 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.”
I am leaning towards D – Invoke-CauScan , with assumption that only to contact WSUS for Update list, not to run the update. ( if the words ” For Updates” means only list)
if the question was mentioning about “schedule” I will def choose Add-CauClusterRole.
In the real world, we won’t have to guest what client wants, we ask them what they want exactly.
I am hoping in the future they make a better question that’s not making the IT have to guest what they want 🙂 , especially IT that have English as second language like me lol
It is D.
Here is a variant question that asks for scheduling windows update for nodes in cluster, where answer would be Add-CauClusterRole instead:
http://www.aiotestking.com/microsoft/which-tool-should-you-use-1044/
it has to be Invoke-CauScan.. Wuauclt and WUSA are for standalone servers.. not for clusters…
and Add-CauClusterRole is for “scheduled” Windows updates… weird question since Add-CauClusterRole also installs the Role in the cluster.. and the question is not asking to deploy a role..
so.. it is not
Add-CauClusterRole
WUSA
Wuauclt
then it most be Invoke-CauScan .. it forces ALL nodes to contact the WSUS server.
I have finally found correct answer since my previous post, it is in fact D!
