Q11. A company has servers that run Windows Server 2012 R2. The company has one Active Directory Domain Services (AD DS) domain.
A user reports that USB devices are not redirected when he uses the Virtual Machine Connection tool to connect to a virtual machine. USB device redirection works for other users that connect to this VM.
You need to ensure that USB devices are redirected for all users when they connect to this VM.
What should you do?
A. Add the user as a member of the Administrators group on the VM.
B. Ensure that the Allow enhanced session mode setting is set to Enabled on the VM.
C. Ensure that the Remote Desktop Services service is running on the VM.
D. Add the user as a member of the Administrators group on the AD DS domain.
Answer: A
Explanation: Ref: http://technet.microsoft.com/en-us/library/dn282274.aspx
Re-direction works for other users on this VM. This means that Enhanced Session Mode is already enabled on the server and VM.
Additionally, Remote Desktop Services needs to be running, and the user account you use to sign in to the virtual machine needs to be a member of the Remote Desktop Users local group or the local Administrators group.
Q12. 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.
You have the following requirements:

hardware virtualization. The Hyper-V role must be installed.
.
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:
.
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.
.
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.

Q16. OTSPOT
You are the virtualization administrator for an organization. You use System Center 2012 R2 Virtual Machine Manager (VMM) to configure a virtual machine (VM) template that will host a new application.
You have the following requirements for new VMs that host the application:
. New VMs must be highly available. . You must join the VMs to an Active Directory Domain Services domain at deployment.
You need to modify the VM template to support the requirements.
On the properties page for the template, which two settings should you configure? To answer, select the appropriate settings in the answer area.
Answer:
78. A company plans to create a Hyper-V environment that will contain three virtual machines (VMs). A limited amount of storage space is available to host the VMs. The VMs will be configured as follows:
You must maximize disk performance.
You need to recommend a storage solution.
Which type of virtual disk type should you configure for each VM?
A. pass-through
B. fixed
C. dynamically expanding
D. differencing
Answer: B
Explanation:
Ref: http://www.petri.co.il/choosing-hyper-v-storage-virtual-hard-disks-2.htm#
Virtual Disk Types
There are considerations for using virtual disks, and what types of virtual disks are available:
.
Fixed—The VHD image file is pre-allocated on the backing store for the maximum size requested.
.
Expandable—Also known as "dynamic", "dynamically expandable", and "sparse", the VHD image file uses only as much space on the backing store as needed to store the actual data the virtual disk currently contains. When creating this type of virtual disk, the VHD API does not test for free space on the physical disk based on the maximum size requested, therefore it is possible to successfully create a dynamic virtual disk with a maximum size larger than the available physical disk free space.
Note The maximum size of a dynamic virtual disk is 2,040 GB.
.
Differencing—A parent virtual disk is used as the basis of this type, with any subsequent writes written to the virtual disk as differences to the new differencing VHD image file, and the parent VHD image file is not modified. For example, if you have a clean-install system boot operating system virtual disk as a parent and designate the differencing virtual disk as the current virtual disk for the system to use. then the operating system on the parent virtual disk stays in its original state for quick recovery or for quickly creating more boot images based on additional differencing virtual disks.
Note The maximum size of a differencing virtual disk is 2,040 GB.
All virtual disk types have a minimum size of 3 MB.
With Pass-through disks, you lose all of the benefits of VHD files such as portability, snap-shotting and thin provisioning.
Performance is marginally better than that of VHD files.

Q18. A company has Active Directory Domain Services (AD DS) domain controllers that run on Windows Server 2012 R2 servers. There are two forests, and each has a single domain. There is a two-way forest trust between the forests. The company uses Hyper-V for server virtualization. The Hyper-V environment contains the Hyper-V host servers as shown in the following table:
You prepare to deploy System Center 2012 R2 Data Protection Manager (DPM) to back up the Hyper-V environment. The deployment must meet the following requirements:
. ensure that all Hyper-V servers can be backed up from a minimum of two DPM servers . minimize the total number of DPM servers
You need to deploy DPM to the environment.
What should you deploy?
A. four DPM servers in the internal network and two DPM servers in the perimeter network
B. two DPM servers in the internal network and one DPM server in the perimeter network
C. two DPM servers in the internal network only
D. two DPM servers in the internal network and two DPM servers in the perimeter network
Answer: C
Explanation:
DPM can protect servers and workstations across domains within a forest that has a two-way trust relationship with the domain that the DPM server is located in. If there is not a two-way trust across domains, you can protect the computers using DPM’s support for computers in workgroups or untrusted domains. For more information, see.Managing Protected Computers in Workgroups and Untrusted Domains.DPM supports data protection across forests as long as you establish a forest-level, two-way trust between the separate forests.
