Requirements

The following functionality is required for resizing a virtual hard disk:

 

clip_image014A server capable of running Hyper-V. The server must have processor support for hardware virtualization. The Hyper-V role must be installed.

clip_image014[1]A user account that is a member of the local Hyper-V Administrators group or the Administrators group.

 

The following functionality is required for resizing a virtual hard disk:

clip_image014[2]VHDX – the ability to expand and shrink virtual hard disks is exclusive to virtual hard disks that are using the .vhdx file format. Online resizing is supported for VHDX disk types, including fixed, differencing, and dynamic disks. Virtual hard disks that use the .vhd file format are not supported for resizing operations.

clip_image014[3]SCSI controller – the ability to expand or shrink the capacity of a virtual hard disk is exclusive to .vhdx files that are attached to a SCSI controller. VHDX files that are attached to an IDE controller are not supported.

 

 

QUESTION 23

You are the virtualization administrator for an organization that manages private and public cloud-based 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.

 

Correct Answer: C

Explanation:

http://technet.microsoft.com/en-us/library/hh831694.aspx

 

CAU is an automated feature that enables you to update clustered servers with little or no loss of availability during the update process. During an Updating Run, CAU transparently performs the following tasks:

 

clip_image014[4]Puts each node of the cluster into node maintenance mode

clip_image014[5]Moves the clustered roles off the node

clip_image014[6]Installs the updates and any dependent updates

clip_image014[7]Performs a restart if necessary

clip_image014[8]Brings the node out of maintenance mode

clip_image014[9]Restores the clustered roles on the node

clip_image014[10]Moves to update the next node

 

For many clustered roles (formerly called clustered applications and services) in the cluster, the automatic update process triggers a planned failover, and it can cause a transient service interruption for connected clients. However, in the case of continuously available workloads such as Hyper-V with live migration or file server with SMB Transparent Failover, CAU can coordinate cluster updates with no impact to the service availability.

 

Note:

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.

You have the following business continuity requirements:

 

clip_image014[11]Virtual machines (VMs) on Server1 must be available within 30 minutes of an unexpected failure.

clip_image014[12]VMs on Server1 must be available if the local datacenter is no longer available.

 

You need to configure the environment.

 

What should you do?

Role/Feature description

Hyper-V Replica provides asynchronous replication of Hyper-V virtual machines between two hosting servers. It is simple to configure and does not require either shared storage or any particular storage hardware. Any server workload that can be virtualized in Hyper-V can be replicated. Replication works over any ordinary IP-based network, and the replicated data can be encrypted during transmission. Hyper-V Replica works with standalone servers, failover clusters, or a mixture of both. The servers can be physically co-located or widely separated geographically. The physical servers do not need to be in the same domain, or even joined to any domain at all.
