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:
CAU is a tool that coordinates software updates on a cluster node, and Configuration Manager also performs
server software updates. It is important to configure these tools so that they do not have overlapping coverage
of the same servers in any data-center deployment. This ensures that the objective behind using CAU is not
inadvertently defeated, because Configuration Manager-driven updating does not incorporate cluster
awareness.
CAU and Configuration Manager can work together to deliver synergistic value. By using the public plug-in
interface architecture in CAU, Configuration Manager can leverage the cluster awareness of CAU. This allows a
customer who already has Configuration Manager deployed to use the cluster awareness capabilities of CAU
while taking advantage of the Configuration Manager infrastructure, such as distribution points, approvals, and
the Configuration console.https://blogs.technet.microsoft.com/filecab/2012/05/17/starting-with-cluster-aware-updating-self-updating/
