What should you include in the plan?

Your network contains two clusters.
The clusters are configured as shown in the following table.
All of the servers in both of the clusters run Windows Server 2012.
You need to plan the application of Windows updates to the nodes in the cluster.
What should you include in the plan? More than one answer choice may achieve the goal. Select the BEST answer.

A.
Cluster-Aware Updating (CAU) self-updating and downloaded updates from Windows Server Update Services (WSUS)

B.
Microsoft System Center 2012 Service Manager integrated with Windows Server Update Service (WSUS)

C.
A manual application of Windows updates on all of the cluster node

D.
Microsoft System Center 2012 Configuration Manager integrated with Windows Server Update Service (WSUS)

Currently, the following Windows Server 2012 clustered workloads are tested and certified for CAU: SMB, Hyper-V, DFS Replication, DFS Namespaces, iSCSI, and
NFS.

This topic provides an overview of Cluster-Aware Updating (CAU), a feature for failover clusters that was introduced in Windows Server 2012. CAU automates the
software updating process on clustered servers while maintaining availability. This topic describes scenarios and applications for using CAU, and provides links to
content that describes how to integrate CAU into other IT automation and management processes.
Practical applications
CAU reduces service outages in clustered services, reduces the need for manual updating workarounds, and makes the end-to-end cluster updating process
more reliable for the administrator. When the CAU feature is used together with continuously available cluster workloads, such as continuously available file
servers (file server workload with SMB Transparent Failover) or Hyper-V, the cluster updates can be performed with zero impact to service availability for clients.
CAU facilitates the adoption of consistent IT processes across the enterprise. You can create Updating Run Profiles for different classes of failover clusters and
then manage them centrally on a file share to ensure that CAU deployments throughout the IT organization apply updates consistently, even if the clusters are
managed by different lines-of-business or administrators.
CAU can schedule Updating Runs on regular daily, weekly, or monthly intervals to help coordinate cluster updates with other IT management processes.
CAU provides an extensible architecture to update the cluster software inventory in a cluster-aware fashion. This can be used by publishers to coordinate the
installation of software updates that are not published to Windows Update or Microsoft Update or that are not available from Microsoft, for example, updates for
non-Microsoft device drivers.
CAU self-updating mode enables a “cluster in a box” appliance (a set of clustered physical machines running Windows Server 2012, typically packaged in one
chassis) to update itself. Typically, such appliances are deployed in branch offices with minimal local IT support to manage the clusters. Self-updating mode
offers great value in these deployment scenarios.
