Q35. You administer two Windows 2012 R2 servers that have the Hyper-V role installed. You plan to deploy a new Hyper-V cluster. The cluster instance must NOT be added to Active Directory. You need to deploy the cluster. What should you do?
A. Use Hyper-V Manager to deploy the cluster.
B. Use Failover Cluster Manager to deploy the cluster.
C. Run the Windows PowerShell cmdlet New-Cluster. Specify ActiveDirectoryAndDNS for the AdministrativeAccessPoint parameter.
D. Run the Windows PowerShell cmdlet New-Cluster. Specify DNS for the AdministrativeAccessPoint parameter.
Answer: D
Explanation:
Ref: http://technet.microsoft.com/en-us/library/dn265970.aspx
To deploy an Active Directory-detached cluster, you must use Windows PowerShell. You
cannot use Failover
Cluster Manager.
To create the failover cluster, start Windows PowerShell as an administrator, and then use
the New-Cluster cmdlet with the –AdministrativeAccessPoint parameter set to a value of
DNS.

. increase the available bandwidth for NYC-WEB . implement network fault tolerance for NYC-WEB without modifying network switch configurations . use the least amount of administrative effort
You need to configure the Hyper-V environment. What should you do first?
A. Enable NIC teaming. Configure the team to use Static Teaming mode.
B. Enable NIC teaming. Configure the team to use Switch Independent mode.
C. Enable Bandwidth Management on NYC-WEB.

Q37. A company has a server that runs Windows Server 2012 R2. The Hyper-V role is installed on the server. The server has virtual machines (VMs) that run Windows Server 2012 R2.
You create two VMs. You also create four virtual hard disks. Two of the virtual hard disks use the VHD file format and two use the VHDX file format.
You plan to create a failover cluster by using the two VMs on the Hyper-V host server.
You need to prepare the storage for the VMs.
What should you do?
A. Enable virtual hard disk sharing for one of the VHDX-based hard disks.
B. Run the Windows PowerShell cmdlet Optimize-VHD against the VHD-based hard disks.
C. Enable virtual hard disk sharing for one of the VHD-based hard disks.
D. Run the Windows PowerShell cmdlet Optimize-VHD against the VHDX-based hard disks.
Answer: A
Explanation:
Ref: http://technet.microsoft.com/en-us/library/dn265980.aspx http://technet.microsoft.com/en-us/library/dn281956.aspx Note: Disk sharing can only be set on VHDX disks. Shared virtual hard disk functionality in guest failover clusters exclusively uses the .vhdx file format. Although the shared virtual hard disk must use the .vhdx file format for the data drive, the operating system disk for a virtual machine can use either the .vhd or the .vhdx file format.
Q38. 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 remain online 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).
Answer: C
Explanation:
CAU is a tool that coordinates software updates on a cluster node, and Configuration Manager also performs server software updates. It is important to configure these tools so that they do not have overlapping coverage of the same servers in any data-center deployment. This ensures that the objective behind using CAU is not inadvertently defeated, because Configuration Manager-driven updating does not incorporate cluster awareness.
CAU and Configuration Manager can work together to deliver synergistic value. By using the public plug-in interface architecture in CAU, Configuration Manager can leverage the cluster awareness of CAU. This allows a customer who already has Configuration Manager deployed to use the cluster awareness capabilities of CAU while taking advantage of the Configuration Manager infrastructure, such as distribution points, approvals, and the Configuration console.

Q39. A company has a Hyper-V failover cluster that consists of sixteen host servers that run Windows Server 2012 R2. The company uses System Center 2012 R2 Virtual Machine Manager (VMM) to manage the Hyper-V environment.
Eight of the host servers are used only for engineering-related services. The other eight host servers are used for general corporate use.
You need to ensure that the corporate virtual machines (VMs) are never moved to the host servers that are used for engineering.
What should you do?
A. Create a new VMM availability set for the corporate VMs.
B. Create a custom property for the corporate VMs and host servers. Then, use a custom placement rule for the host group. Specify that the rule must match.
C. In the corporate VMs, set the value of the Preferred Owners setting to the names of the corporate host servers.
D. Create a new VMM availability set for the corporate host servers.
Answer: B

Q40. 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.
