You are the virtualization administrator for an organization that manages private and public cloud- based resources.
The organization uses Windows Server 2012 R2 servers that have the Hyper-V role installed.
All Hyper-V host servers are configured as nodes in a four-node cluster.
The organization also uses System Center 2012 R2 Configuration Manager.
Operating system updates to each host server require a system reboot.
You need to ensure that the virtual machines remain online during any reboots required by the updates.
What should you do?
A.
in System Center 2012 R2 Configuration Manager, add all of the servers to a collection.
Deploy updates to the collection.
B.
Apply updates by using the Virtual Machine Servicing Tool (VMST).
C.
Implement cluster-aware updating with the Cluster-Aware Updating (CAU) wizard.
D.
Configure orchestrated updates of Hyper-V host clusters in System Center 2012 R2 Virtual Machine Manager (VMM).
Explanation:
NOT C
CAU is for non hyper-v clusters
ANWSER should be D
Hyper-V clusters that have virtual machines with Hyper-V Network virtualization networks always use VMM for patching and live migration.

Managing Fabric Updates in VMM
http://technet.microsoft.com/en-us/library/gg675084.aspx
Why should you manage fabric updates through VMM?
Fabric servers include the following physical computers managed by VMM: Hyper-V hosts and Hyper-V clusters, library servers, Pre-Boot Execution Environment
(PXE) servers, the Windows Server Update Management (WSUS) server, and the VMM management server.
VMM supports on demand compliance scanning and remediation of the fabric. Administrators can monitor the update status of the servers. They can scan for
compliance and remediate updates for selected servers. Administrators also can exempt resources from installation of an update.
VMM supports orchestrated updates of Hyper-V host clusters. When a VMM administrator performs update remediation on a host cluster, VMM places one
cluster node at a time in maintenance mode and then installs updates. If the cluster supports live migration, intelligent placement is used to migrate virtual machines
off the cluster node. If the cluster does not support live migration, VMM saves state for the virtual machines.
