Q11. 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.

Q14. A company has a Windows Server 2012 R2 server named NYC-HOST1 that has the Hyper-V role installed. The host server hosts two virtual machines named SALES1 and SALES2. NYC-HOST1 uses storage spaces with tiered storage. The storage spaces contain both solid state disks (SSDs) and 10,000 RPM Serial Attached SCSI (SAS) disks for .vhdx files. Each virtual machine runs on its own .vhdx file.
You plan to add new virtual machines each month. SALES1 and SALES2 must run at the highest possible performance at all times.
You need to configure the virtual machines.
What should you do?
A. Add additional SSDs to the storage space that is occupied by SALES1 and SALES2.
B. Replace the 10,000 RPM SAS disks with 15,000 RPM SAS disks.
C. Move the .vhdx files from the storage spaces to individual SAS hard disks.

Q15. A company has one Active Directory Domain Services (AD DS) forest that contains two domains. All servers run Windows Server 2012 R2. The company uses iSCSI storage and Fibre Channel storage.
You plan to deploy a single Hyper-V failover cluster that uses Cluster Shared Volumes (CSV). The cluster must include virtual machines from both domains.
You need to ensure that you can deploy a failover cluster.
What should you do?
A. Join each Hyper-V host server to the same AD DS domain.
B. Deploy clustered storage spaces.
C. Deploy Serial Attached SCSI (SAS).
D. Join each Hyper-V host server to different AD DS domains.
Answer: A
Explanation:
Ref: http://technet.microsoft.com/en-us/library/dn505754.aspx Domain role: All servers in the cluster must be in the same Active Directory domain. As a best practice, all clustered servers should have the same domain role (either member server or domain controller). The recommended role is member server.
Q16. RAG DROP
A company uses System Center 2012 R2 Virtual Machine Manager (VMM).
You need to create and assign a self-service user role in VMM.
You have the following requirements:
. All role members must share ownership of all virtual machines (VMs) that any role
member creates.
. Role members must be able to deploy VMs.
. Role members must NOT have authoring rights.

Q19. A company has a new Hyper-V host server that runs Windows Server 2012 R2 Datacenter edition. You plan to deploy a new virtual machine (VM).
You must install Windows Server 2012 R2 Standard edition on the VM from a standard network adapter by using PXE boot. The VM must boot to a SCSI VHDX disk.
You need to create the VM.
What should you create?
A. a storage pool that uses SCSI disks
B. a Generation 1 VM
C. a Generation 2 VM
D. a virtual disk that uses the VHDX format
Answer: C
Explanation:
http://technet.microsoft.com/en-us/library/dn282285.aspx http://www.serverwatch.com/server-tutorials/hyper-v-2012-r2-pros-and-cons-of-generation-1-vs.-generation-2-vms.html
A virtual machine created with Generation 1 supports legacy drivers and uses Hyper-V BIOS-based architecture. Hyper-V BIOS-based virtual machines can only initialize IDE Controller for Operating System to initialize a file system, which is shown in the below image: C:\Documents and Settings\Adnan Hameed\Desktop\untitled.PNG
On the other hand, a virtual machine created with Generation 2 supports UEFI-based architecture, in which a subset of Integration Service components has been included to allow SCSI Controller to initialize before the Operating System starts loading This is shown in the below image: C:\Documents and Settings\Adnan Hameed\Desktop\untitled.PNG
What you see in the above screenshot is that the Generation 2 Virtual Machine no longer loads the legacy drivers (IDE and Legacy Network Adaptors) A majority of the legacy drivers have been removed from a virtual machine that has been created using Generation 2, but a subset of Integration Services components has been included to initialize at boot and before control is returned to the Operating System. This includes initializing and loading SCSI Controller driver before the Operating System starts loading.
Q20. A company has Windows Server 2012 R2 servers that have the Hyper-V role installed. The guest virtual machines are configured as follows:
You need to configure the environment to support the creation of failover clusters. What should you do?
A. Convert the data drives to use the VHDX file format.
B. Convert the operating system drive to use the virtual hard disk (VHD) file format.
C. Convert the virtual machines to Generation 2 virtual machines.
D. Upgrade the operating system to Windows Server 2012 R2.
Answer: A
Explanation: 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. Generation 1 and Generation 2 virtual machines are supported in a guest failover cluster using a shared virtual hard disk.
