  Q: What is the new Guest services integration service in Windows Server 2012 R2 Hyper-V?

  A: Several integration services are available for virtual machines (VMs) such as time synchronization, heartbeat, backup, OS shutdown, and data exchange. In Windows Server 2012 R2, a new integration service has been added, Guest services. Guest services enables the copying of files to a VM using WMI APIs or using the new Copy-VMFile Windows PowerShell cmdlet.

  You need to find servers which CANNOT go thru P2V migration.

  P2V Prerequisites in VMM

  Requirements on the source machine

  The physical computer to be converted must meet the following requirements:

  -Must have at least 512 MB of RAM.

  -Cannot have any volumes larger than 2040 GB.

  - Must have an Advanced Configuration and Power Interface (ACPI) BIOS. Vista WinPE will not install on a non-ACPI BIOS.

  -Must be accessible by VMM and by the virtual machine host.

  -Cannot be in a perimeter network.

  --> A perimeter network, which is also known as a screened subnet, is a collection of devices and subnets that are placed between an intranet and the Internet to help protect the intranet from unauthorized Internet users. The source computer

  for a physical-to-virtual (P2V) conversion can be in any other network topology in which the VMM management server can connect to the source machine to temporarily install an agent and can make Windows Management Instrumentation

  (WMI) calls to the source computer.

  - The source computer should not have encrypted volumes. --> If the source computer has encrypted volumes, an offline P2V conversion may render the computer unbootable.

  Answer: So based on the prerequisites, NYC-FS, NYC-EX and NYC-PR needs to be re- configured.

  UPDATE:

  As of System Center 2012 R2, you can no longer perform P2V conversions in VMM. For information about how to use an earlier version of Virtual Machine Manager to mitigate this change, see the:

  "How to perform a P2V in a SCVMM 2012 R2 environment blog" - http://blogs.technet.com/b/scvmm/archive/2013/10/03/how-to-perform-a-p2v-in-a-scvmm-2012- r2-environment.aspx

• Question 87:

  You use System Center 2012 R2 Virtual Machine Manager (VMM) to manage a Hyper-V environment that consists of two host groups named Dev1 and Prod1. It also has two private clouds named DevCloud and ProdCloud.

  You have a self-service user role named DevVMAdmins. DevVMAdmins does NOT have the rights to perform any actions. DevVMAdmins must have the ability to start virtual machines (VMs), stop VMs, and shut down VMs. It must also be able to use resources from other self- service users.

  You need to configure the DevVMAdmins user role.

  How should you complete the relevant Windows PowerShell command? To answer, drag the appropriate Windows PowerShell segments to the correct locations in the cmdlet. Each Windows PowerShell segment may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

  All virtual machines must be highly available. You need to configure the environment. What should you implement?

  A. a separate Hyper-V replica between NYC-Host1 and SFC-Host1
  B. a Hyper-V cluster that includes NYC-Host1, NYC-Host2, and SFC-Host1
  C. a Hyper-V cluster between NYC-Host1 and SFC-Host1
  D. a Hyper-V replica between NYC-Host1 and NYC-Host2 with an extended replica between NYC-Host1 and SFC-Host1
  D. a Hyper-V replica between NYC-Host1 and NYC-Host2 with an extended replica between NYC-Host1 and SFC-Host1

  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.

• Question 89:

  A company has a Windows Server 2012 R2 Hyper-V environment that contains a single Active Directory Domain Services domain named Contoso.com. The environment also has three servers named Host1, Host2, and Host3 that have the

  Hyper-V role installed. You configure all of the hosts as a single failover cluster.

  You have two guest clusters named VM-Cluster1 and VM-Cluster2. The environment is configured as shown in the following diagram:

  

  When a virtual machine guest cluster node is migrated to another host, the guest cluster fails over to the other node. You must provide high availability for all virtual machines. Guest clusters must NOT fail over if they are migrated to another

  host.

  You need to configure the guest clusters.

  http://technet.microsoft.com/en-us/library/dn440540.aspx Protect against short-term network interruptions

  Failover cluster nodes use the network to send heartbeat packets to other nodes of the cluster. If a node does not receive a response from another node for a specified period of time, the cluster removes the node from cluster membership.

  By default, a guest cluster node is considered down if it does not respond within 5 seconds. Other nodes that are members of the cluster will take over any clustered roles that were running on the removed node.

  Typically, during the live migration of a virtual machine there is a fast final transition when the virtual machine is stopped on the source node and is running on the destination node. However, if something causes the final transition to take

  longer than the configured heartbeat threshold settings, the guest cluster considers the node to be down even though the live migration eventually succeeds.

  If the live migration final transition is completed within the TCP time-out interval (typically around 20 seconds), clients that are connected through the network to the virtual machine seamlessly reconnect.

  To make the cluster heartbeat time-out more consistent with the TCP time-out interval, you can change the SameSubnetThreshold and CrossSubnetThreshold cluster properties from the default of 5 seconds to 20 seconds.

  By default, the cluster sends a heartbeat every 1 second. The threshold specifies how many heartbeats to miss in succession before the cluster considers the cluster node to be down.

• Question 90:

  You administer a Windows Server 2012 R2 server that has the Hyper-V role installed. You plan to test an update to a virtual machine (VM) in a production environment. You must meet the following requirements: migrate the VM to another Hyper-V host as quickly as possible ensure that the VM configuration is preserved after the migration is complete

  You need to migrate the virtual machine. What should you do first?

  A. Create a checkpoint of the VM.
  B. Run the Windows PowerShell cmdlet Export-VMSnapshot.
  C. Run the Windows PowerShell cmdlet New-VirtualDiskClone.
  D. Export the VM.
  D. Export the VM.

  This is the way to preserve the configuration after the migration on both of the hosts the "source" host will keep the powered off state of the VM and on the "destination" host will run the "migrated" VM.
