Q12. You have three Windows Server 2012 R2 servers that are set up as a Hyper-V cluster. You use System Center 2012 R2 Virtual Machine Manager to manage the Hyper-V environment.
Users report that when a Hyper-V host server becomes overloaded, the performance of the virtual machines is unacceptable.
You need to analyze workloads and automatically migrate virtual machines from overloaded host servers to host clusters that have available capacity.
What should you configure?
A. Performance and Resource Optimization (PRO)
B. Placement Rules
C. shared .vhdx file
D. Dynamic Optimization
Answer: D
Explanation: Ref: http://technet.microsoft.com/en-us/library/gg675109.aspx Dynamic Optimization in VMM During Dynamic Optimization, VMM migrates virtual machines within a host cluster to improve load balancing among hosts and to correct any placement constraint violations for virtual machines.
Dynamic Optimization can be configured on a host group, to migrate virtual machines within host clusters with a specified frequency and aggressiveness. Aggressiveness determines the amount of load imbalance that is required to initiate a migration during Dynamic Optimization. By default, virtual machines are migrated every 10 minutes with medium aggressiveness. When configuring frequency and aggressiveness for Dynamic Optimization, an administrator should factor in the resource cost of additional migrations against the advantages of balancing load among hosts in a host cluster. By default, a host group inherits Dynamic Optimization settings from its parent host group.
Dynamic Optimization can be set up for clusters with two or more nodes. If a host group contains stand-alone hosts or host clusters that do not support live migration, Dynamic Optimization is not performed on those hosts. Any hosts that are in maintenance mode also are excluded from Dynamic Optimization. In addition, VMM only migrates highly available virtual machines that use shared storage. If a host cluster contains virtual machines that are not highly available, those virtual machines are not migrated during Dynamic Optimization. On demand Dynamic Optimization also is available for individual host clusters by using the Optimize Hosts action in the VMs and Services workspace. On demand Dynamic Optimization can be performed without configuring Dynamic Optimization on host groups. After Dynamic Optimization is requested for a host cluster, VMM lists the virtual machines that will be migrated for the administrator's approval.
Q13. You administer a server that runs Windows Server 2012 R2 with the Hyper-V role installed. You plan to deploy a new virtual machine (VM) to the server. The data stored by the VM doubles each month.

Q14. A company has an Active Directory Domain Services (AD DS) environment. All domain controllers run Windows Server 2012 R2. The company also has a virtualization infrastructure that consists of two Hyper-V host servers. The host servers and all of the virtual machine (VMs) run Windows Server 2012 R2.
The company must deploy VMs by using file shares that use the Server Message Block (SMB) protocol. You create a file share. You must follow the principle of least privilege.
You need to implement the NTFS and share permissions required to use the file share.
Which objects should you grant permissions to?
A. Hyper-V service accounts and the LocalSystem account
B. LocalSystem and all Hyper-V administrators
C. computer objects for the VMs, the SYSTEM account, and all Hyper-V administrators
D. computer objects for the Hyper-V host servers, the SYSTEM account, and all Hyper-V administrators

Q16. An organization has private and public cloud resources. The organization has Windows Server 2012 R2 servers that have the Hyper-V role installed. You have one four-node cluster of Hyper-V host servers. You use System Center 2012 R2.
The virtual machines that run on the cluster must remain online when you install updates on the Hyper-V host servers.
You need to install updates on the Hyper-V host servers.
What should you do?
A. Configure Windows Server Update Services (WSUS) to provide updates to the Hyper-V host servers in the cluster.
B. Add all the virtual machines hosted on the cluster to a collection in System Center 2012 R2 Configuration Manager. Deploy updates to the collection.
C. Use the Cluster-Aware Updating (CAU) wizard.
D. Configure Windows Update on the Hyper-V host servers to download updates from Microsoft Update.
Answer: C
Explanation:
Ref: http://technet.microsoft.com/en-us/library/gg675084.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:
.
Puts each node of the cluster into node maintenance mode
.
Moves the clustered roles off the node
.
Installs the updates and any dependent updates
.
Performs a restart if necessary
.
Brings the node out of maintenance mode
.
Restores the clustered roles on the node
.
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.
