B. Enable streaming on the vDisk.

C. Reset the Active Directory machine account password.

D. Change the vDisk access mode to Private Image mode.

Scenario: An administrator needs to remove QoS processing from a virtual machine. The virtual machine is experiencing performance issues with web traffic in a XenServer environment with a global QoS policy applied.

Which configuration change should the administrator make to satisfy this requirement?

A. Disable inherited QoS policy

B. Inherit QoS policy from parent

C. Apply a QoS limit of 1000 Kbps

What should the administrator do to get the two new virtual machines to start?

A. Disable XenServer Tools.

B. Configure workload balancing.

C. Enable dynamic memory control.

D. Assign virtual machines to a vApp.

Which two policy modes must the administrator apply to implement a XenServer workload balancing policy to reduce power consumption and energy costs during off peak hours? (Choose two.)

A. Maximize Density

B. Fixed Optimization

C. Maximize Performance

D. Scheduled Optimization

Scenario: After a host failure, an administrator rebuilt the host and restored the XenServer pool database. However, all virtual machines are registered as suspended.

Which command can the administrator use to correct the situation?

A. xe vm-reboot vm=vm_name

B. xe vm-shutdown vm=vm_name

C. xe vm-unpause vm=vm_name --multiple

D. xe vm-reset-powerstate vm=vm_name -force

Scenario: Users are NOT able to log into XenCenter using their Active Directory credentials. The administrator checked to ensure that the XenServer host exists as a valid computer object in Active Directory.

What should the administrator do to ensure that users are able to authenticate successfully using XenCenter?

A. Recreate the XenServer host computer object in Active Directory.

B. Ensure that the XenServer host and domain controller are in the same time zone.

C. Check that the time is synchronized between Active Directory and the XenServer host.

D. Set up the correct delegation on the XenServer host computer object in Active Directory.

Scenario: An administrator built four new hosts in an existing XenServer pool that already has multiple hosts connected to a shared storage over Fibre Channel. The administrator discovered that the new hosts are NOT able to connect to the existing storage repositories.

Which two steps can the administrator take to resolve the issue? (Choose two.)

A. Check the log files.

B. Recreate the storage repositories.

C. Verify that the LUNs are mapped and zoned correctly.

D. Convert the storage repositories to shared storage repositories.

Scenario: In preparation for adding a new iSCSI SAN to the environment, an administrator needs to separate the storage traffic from the XenServer management traffic. The host is connected to the iSCSI SAN on the 192.168.30.0/24 subnet using NIC 3.

What must the administrator create to separate the storage network traffic?

A. A management interface

B. An external network

C. A bonded network

D. A single-server private network
