Q46. A Windows Server 2012 R2 Hyper-V host server has four network adapters that are connected to two different network switches. The server contains a virtual machine named NYC-WEB.
You have the following requirements:
. 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.
D. Run the Windows PowerShell command Set-NetLbfoTeam -Name Team1 -TeamingMode Static.

Q47. 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. Run the Windows PowerShell cmdlet New-Cluster. Specify DNS for the AdministrativeAccessPoint parameter.
B. Run the Windows PowerShell cmdlet New-Cluster. Specify Forest for the AdministrativeAccessPoint parameter.
C. Run the Windows PowerShell cmdlet Get-Cluster. Specify DNS for the Domain parameter.
D. Run the Windows PowerShell cmdlet New-Cluster. Specify ActiveDirectoryAndDNS for the AdministrativeAccessPoint parameter.
Answer: A
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.
Q48. 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.

Q49. 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

Q50. 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.
