You are the virtualization administrator for an organization that manages private and public cloudbased resources. The organization uses Windows Server 2008 R2 SP1 Hyper-V. All Hyper-V host
servers are configured as nodes in a four-node cluster. The organization also uses System Center
2012 R2.
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.
Apply updates by using the Virtual Machine Servicing Tool (VMST).
B.
Configure orchestrated updates of Hyper-V host clusters in System Center 2012 R2 Virtual
Machine Manager (VMM).
C.
Implement cluster-aware updating with the Cluster-Aware Updating (CAU) wizard.
D.
In System Center 2012 R2 Configuration Manager, add all of the servers to a collection. Deploy
updates to the collection.
I’d go for C, as it’s less effort than building Orchestrator runbook and it’s automated as well.
Apparently it can’t be C since the cluster includes some 2008 hosts.
According to https://technet.microsoft.com/en-us/library/hh831694(v=ws.11).aspx
“The CAU feature is only compatible with Windows Server 2012 R2 and Windows Server 2012 failover clusters and the clustered roles that are supported on those versions.”
I believe this process is what answer B is referring to: https://technet.microsoft.com/en-us/library/gg675088(v=sc.12).aspx
