An organization has private and public cloud resources. The organization has Windows Server 2012 R2 servers
that have the Hyper-V roll installed. You have one four-node cluster of Hyper-V host servers. You use System
Center 2012 R2.
The virtual machines that run on the cluster must remain online when you install updates on the Hyper-V host
servers.
You need to install updates on the Hyper-V host servers.
What should you do?
A.
Configure Windows Server Update Services (WSUS) to provide updates to the virtual machines hosted on
the cluster.
B.
Add all the servers to a collection in System Center 2012 R2 Configuration Manager.
Deploy updates to the collection.
C.
Create orchestrated updates of Hyper-V host clusters by using System Center 2012 R2 Virtual Machine
Manager (VMM).
D.
Configure Windows Update on the Hyper-V host servers to download updates from Microsoft Update.
I would have to go with C.

I agree!!
C is indeed correct option.
Answer is A , this is kind of a tricky question since the updating takes several steps wich I think are:
Step1: install a WSUS server for VMM, enable update management, create update baselines for computers managed by VMM, and scan the computers for compliance.
Step2: Use the following procedure to orchestrate rolling updates of a Hyper-V host cluster that is managed by System Center 2012 – Virtual Machine Manager (VMM).
VMM rolls through the host cluster, remediating one cluster node at a time. If a cluster node is compliant, VMM bypasses that node.
Before VMM begins remediating a host in a cluster, it places the host in maintenance mode. You have the option of migrating all virtual machines to other hosts in the cluster. If you do not select this option, VMM saves state and does not migrate virtual machines.
Since the question asks WHAT should you do to install the updates onto the Hyper-V host servers I would take “A” as the answer.
This can be read on the note from the link posted on the OP by Steve.
SIDE NOTE: In this case we could use Cluster-Aware Updating (CAU) since all the requirements are meet, but this isn’t offered in the answers.
The question says updates on hyper-v hosts and not VMs
Option A is talking about WSUS for VMs and not hosts
C should be the correct answer if you want to update hyper-V hosts AND make sure the guest VMs are online
Kamex CAU dont meet the requirements because the question says “You use System
Center 2012 R2.” and CAU is not a part of VMM and the VMs must remain online but CAU cant live migrate them it saves their state and shutdown before updating the node
CAU is part of fail over clustering and the question states that the Hyper-V hosts are in a cluster. Only options to install updates while the VM’s remain online is using CAU or orchestrated ubdates using VMM. Though the question doesn’t explicitly mention VMM is available, cloud resources are used and you need VMM to build these.
So CAU is available and orchestrated updates thru VMM. First option is not a possible answer, so it is C
Namhar is correct – C is the answer
I agree with “C”
The Remediate action is only available after you install a WSUS server for VMM, enable update management, create update baselines for computers managed by VMM, and scan the computers for compliance. For more information, see Managing Fabric Updates in VMM.

strangertoall:
it is true that you need WSUS installed for the HOSTS and then VMM will work correctly. But Answer “A” states “provide updates to the VIRTUAL MACHINES”, configuring A will not do live updates on the host. However accomplishing C implies WSUS is set up for the HOSTS.
Answer is C.
I also have an answer in Noor : Use Cluster aware updating (CAU) wizard.
