You are the virtualization administrator for an organization.
The organization uses all components of System Center 2012 R2 in its production environment.
You need to configure the environment to support Performance and Resource Optimization (PRO).
How should you configure the environment? To answer, drag the appropriate server role to the correct location or locations. Each server role 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.
 
Answer:
 
Explanation:
Install the VMM console. -> Not stated but by default it will install in de VMM server
http://technet.microsoft.com/en-us/library/hh882399.aspx
Enable Agent Proxy for the Operations Manager agent. ->
5. Verify that the managed hosts on which you installed agents are visible in Operations Manager by performing the following actions:
a. In the Operations console, click Administration.
b. In the Administration pane, under Device Management, click Agent Managed. Verify that the expected hosts are listed.
c. If you are running System Center 2012 SP1 or System Center 2012 R2, double-click a host in the list, click the Security tab, and then ensure that Allow this agent to act as a proxy and discover managed objects on other computers has been selected. Repeat this step for each of the hosts.
http://technet.microsoft.com/en-us/library/hh882396.aspx
So I think the answer is:
Install VMM Console on VMM server
Enable Proxy for each Hyper-V host

QUESTION 3
Drag and Drop Question
You administer a Hyper-V environment that uses Windows Server 2012 R2 and System Center 2012 R2 Virtual Machine Manager (VMM).
A line-of-business (LOB) application requires two virtual machines (VMs).
Each VM must have direct access to existing Fibre Channel storage.
You need to ensure that the two VMs have direct access to Fibre Channel storage.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
 
Answer:
 
Explanation:
The answer for Part #1 is here: http://technet.microsoft.com/en-us/library/dn458365.aspx
The steps for #2 and #3 are here – You first create the virtual SAN then add the virtual HBA: http://technet.microsoft.com/en-us/library/dn458369.aspx
1. Install a storage area network (SAN) that supports only N-Port ID Virtualization (NPIV).
2. Configure each Hyper-V host server with at least one virtual storage area network (SAN).
Add a Fibre Channel adapter to each VM.
3. Configure the Hyper-V host servers with one or more Fibre Channel host bus adapters (HBAs). Connect the Hyper-V host servers to the storage area network (SAN).

QUESTION 4
Drag and Drop Question
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.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
 
Answer:
 
Explanation:
If you want all role members to share ownership of all virtual machines that any member creates, create a security group in Active Directory and assign that group to the user role. An alternate method for sharing resources among Self-Service User role members is to use the Share and Receive actions, discussed later, which enable resource owners who are self-service users to share individual resources with one or all members of a Self-Service User role.
If you plan to use this user role to test deploying virtual machines and services to a private cloud, be sure to add yourself as a member.
Because of the share ownership you have te use a security group as stated above.
http://technet.microsoft.com/en-us/library/gg610613.aspx

QUESTION 5
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 visualization.
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 by using DPM
– Hyper-v hosts in the perimeter network Must use certificate-based authentication
– Hyper-V hosts in the internal network Must use Kerberos authentication 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 only
C.    two DPM servers in the internal network and two DPM servers in the perimeter network
D.    two DPM servers in the internal network and one DPM server in the perimeter network

Answer: D
Explanation:
http://technet.microsoft.com/en-us/library/hh916530.aspx
“DPM supports protecting DPM SERVERS THAT ARE IN UNTRUSTED DOMAINS if the primary and secondary DPM servers are in domains that trust each other or if they are in the same domain”.
So there must be at least one DPM Server in the untrusted domain in order for the two DPM servers in the internal network to protect it.
http://technet.microsoft.com/en-us/library/hh757954.aspx
“Restrictions: Protection of perimeter network (DMZ) machines is not supported in DPM.”
So there must be another DPM Server in the untrusted domain in order for the two DPM servers in the internal network to protect it.

QUESTION 6
You administer a Windows Server 2012 R2 Hyper-V host server that contains production and test virtual machines (VMs).
You plan to optimize the performance of the VMs.
The following settings must be applied to the VMs:
– You must set a maximum value for the input/output operations per second (IOPS) on the test VMs.
– You must set a minimum value for the IOPS on the production VMs.
You need to configure the environment.
What should you do?

A.    On all VMs, enable Network Quality of Service (QoS).
B.    Create a shared virtual hard disk (VHD).
C.    On the Hyper-V host server, enable Resource Metering.
D.    On all VMs, enable Storage Quality of Service (QoS).

Answer: D
Explanation:
http://technet.microsoft.com/en-us/library/dn282281.aspx
Key benefits
Storage QoS provides the ability to specify a maximum input/output operations per second (IOPS) value for your virtual hard disk. An administrator can throttle the storage I/O to stop a tenant from consuming excessive storage resources that may impact another tenant.
An administrator can also set a minimum IOPS value. They will be notified when the IOPS to a specified virtual hard disk is below a threshold that is needed for its optimal performance.
The virtual machine metrics infrastructure is also updated, with storage related parameters to allow the administrator to monitor the performance and chargeback related parameters.
Maximum and minimum values are specified in terms of normalized IOPS where every 8 K of data is counted as an I/O.

QUESTION 7
Drag and Drop Question
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.
 
Answer:
 
Explanation:
Set-SCUserRole
Modifies the settings for an existing VMM user role.
* The actions that you can grant a Self-Service user include the following:
CanReceive Receive resources from other self-service users
*Parameter: -Permission<SelfServicePermission[]>
Specifies the actions that members of a Self-Service User role can perform on their virtual machines or services.
Valid values are: AllowLocalAdmin, Author, CanShare, CanReceive, Checkpoint, CheckpointRestoreOnly, Create, CreateFromVHDOrTemplate, PauseAndResume, RemoteConnect,
Remove, Save, Shutdown, Start, Stop, Store.

QUESTION 8
A company uses System Center 2012 R2 Virtual Machine Manager (VMM).
You have the following requirements:
– Self-service users must be able to store and share their resources.
– Self-service users must be able to use the resources to create profiles and templates in VMM.
You need to configure VMM to support self-service users.
Which three actions should you perform? Each correct response presents part of the solution.

A.    In the VMM library share, create a user data path.
B.    Grant the Read permission and the Write permission to all role members.
C.    In the Public Documents share, create a user data path.
D.    Assign the Deploy action to the role members.
E.    Grant the Read & execute permission to all role members.
F.    Assign the Author action to the role members.

Answer: ABF
Explanation:
http://technet.microsoft.com/en-us/library/gg610608.aspx
Configuring the Library to Support Self-Service Users
Answer A: – As of VMM in System Center 2012, self-service users can use the VMM console, and can see their logical and physical resources in the Library workspace.
Answer B: – Self-service user data paths Configure user data paths on self-service user roles to provide a place where members of a self-service user role can upload and share their own resources. The user data path also is the best place for administrators to store resources that only members of a self-service user role need to use. For example, a user data path might store the application packages for services that a self-service user role deploys. Permissions on the user data path are controlled through the file system. VMM discovers all files that the current self-service user has access to. Access control permissions determine whether the users have Read/Write or Read/only access.
Answer: F- As of VMM in System Center 2012, self-service users who are assigned the Author action can create their own templates and profiles, and can share their service templates and virtual machine templates with other self-service users. A user data path is provided to the self-service user role to enable those users to upload and share their own resources.
* Deploy
Grants members permission to deploy virtual machines and services from templates and virtual hard disks that are assigned to their user role. However, they do not have the right to author templates and profiles.

QUESTION 9
You have a Windows Server 2012 R2 Hyper-V environment that includes System Center 2012 R2 Virtual Machine Manager (VMM).
The environment includes five physical servers.
The servers are configured as follows:
You plan to use VMM to migrate physical machines to virtual machines.
You need to reconfigure the hardware on the servers to support a physical to virtual offline migration.
Which three servers should you reconfigure? Each correct answer presents part of the solution.
 

A.    NYC-DEV
B.    NYC-WEB
C.    NYC-PR
D.    NYC-FS
E.    NYC-EX

Answer: CDE
Explanation:
The question is of which three servers the hardware should be reconfigured to allow P2V migration.
Answer A and B are not correct, as both servers meet the hardware requirements for a P2V migration and we are looking for the servers which do not meet the hardware requirements.
Answer D and E are correct, as both have disk volumes larger than 2TB, which is not supported for a P2V migration.
That leaves us with answer C. According to “tvojahlava”, the server NYC-PR has 256MB RAM on the exam, which is less than what is supported for a P2V migration.
Answer C, D and E are correct therefore.

QUESTION 10
You administer a Virtual Desktop Infrastructure (VDI).
The environment runs on a Windows Server 2012 R2 server that has the Hyper-V role installed. You use Systems Center 2012 R2 Operations Manager to troubleshoot performance issues.
Some users of dedicated virtual desktops report slow response times within their sessions. Operations Manager reports indicate that a performance bottleneck exists at the storage layer.
You need to manage the amount of input/output operations per second (IOPS) that the dedicated desktop pool can generate.
What should you do?

A.    Enable Resource Metering on the Hyper-V host server.
B.    Configure Operations Manager to monitor virtual machine disk performance on the Hyper-V
host server.
Configure monitoring alerts for virtual machine use greater than the allowed IOPS.
C.    For each virtual machine, enable Network Quality of Service (QoS).
Set a minimum and max mum value for the Mbps property.
D.    For each virtual machine, enable Storage Quality of Service (QoS).
Set a minimum and maximum value for IOPS.

Answer: D
Explanation:
http://technet.microsoft.com/en-us/library/dn282281.aspx
Network Quality of Service cannot mannage input/output operations per second (IOPS).
You need Storage Quality of Service for this.
