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 remainonline 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).
iam a little bit confuses…when to use cau or orchestrated updates…is there a brief explanation or who’s willing to share ?

In this situation there is no VMM to do orchestrated updates as it only says “System Center 2012 R2 Configuration Manager.” So you have to use the best thing available which would be CAU

There are two similar questions. In on the organization uses Windows Server 2012 R2, in other The organization uses Windows Server 2008 R2 Hyper-V. CAU is 2012 feauter. In case of 2008 we use orchestrated updates.

Answer is C
Cluster-Aware Updating (CAU) is a feature that coordinates software updates on all servers in a failover cluster in a way that does not impact the service availability any more than a planned failover of a cluster node. For some applications with continuous availability features (such as Hyper-V with live migration, or an SMB 3.0 file server with SMB Transparent Failover), CAU can coordinate automated cluster updating with no impact on service availability.

The Answer is definitely not C.
Cluster-Aware updating requires windows 2012 / windows 2012R2 Clusters – which are not present here.

Dope – ignore my previous comment I confused myself with the similar questions – answer is C!!

In fact there are 3 similar questions:
1) windows 2008 –> orchestrated updates
2) windows 2012R2 –> CAU (when WSUS is not mentioned)
3) windows 2012R2 with VMM and WSUS –> Install WSUS
–> this combination will use CAU as well if it detects a cluster
