2 QUESTION: 107 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., C QUESTION: 108 An administrator noticed that a storage repository is unable to attach or be repaired in the XenCenter console. Which command can the administrator run in the XenServer CLI to reconnect the storage repository? A. xe sr-scan B. xe sr-probe C. xe pbd-plug D. xe pbd-unplug Answer: C QUESTION: 109 An administrator needs to resolve intermittent host issues related to high availability. Which two actions can the administrator take to resolve this issue? (Choose two.) A. Change storage repositories. B. Implement Disaster Recovery. C. Implement workload balancing. D. Change management networks., D QUESTION:

3 Scenario: An administrator has noticed that all storage repositories in XenCenter are shown as using 0 bytes of space. The administrator has determined that the XAPI database must be in sync with the local VDIs presented on the underlying storage substrate. Which command should the administrator run to resolve this issue? A. xe sr-scan B. xe sr-probe C. xe sr-forget D. xe sr-introduce QUESTION: 111 Scenario: An administrator receives a change request to enable high availability in a resource pool consisting of six XenServer hosts. When the administrator is executing the change request, an error message indicates there is an issue with enabling high availability. What could be causing this issue? A. NTP is NOT specified. B. Hosts have different CPUs. C. Active Directory authentication is NOT configured. D. The storage repository disk space for heart-beat is insufficient. Answer: D QUESTION: 112 Scenario: An administrator CANNOT use XenCenter to manage an existing XenServer host in a resource pool. The administrator found that the XenServer host CANNOT communicate properly with XAPI. What could be causing the communication issue on the failed host? A. Dom0 is out of space. B. NTP is NOT configured. C. The root password is unknown. D. The host CANNOT connect to Active Directory. QUESTION:

4 Scenario: An administrator manages six XenServer hosts in a resource pool in which high availability is enabled. The administrator is notified that host fencing occurred. Which two reasons could be causing the issue? (Choose two.) A. CPU utilization reached 90%. B. The resource pool is overcommitted. C. The shared storage repository was disconnected. D. There was a XenServer management network outage. Answer: C, D QUESTION: 114 An administrator CANNOT use XenCenter to connect to an existing standalone XenServer host that has six virtual machines running. What could be causing this issue? A. NTP is NOT configured. B. The XAPI Service stopped. C. The XenServer DNS configuration is incorrect. D. Communication with Active Directory has been lost. Answer: B QUESTION: 115 Scenario: An administrator tries to start a virtual machine on a host that has an NFS storage repository. The virtual machine gives the error "This virtual machine needs storage that cannot be seen from the server." Which action, within XenCenter, can the administrator take on the NFS storage repository to correct this issue? A. Repair B. Forget C. Detach D. Set as default QUESTION: 116 Scenario: An administrator manages a XenServer resource pool consisting of six XenServer hosts. A Windows XP virtual machine runs on a shared NFS storage repository. The administrator needs to migrate the Windows XP virtual machine to another host but CANNOT. What must the administrator do to migrate the Windows XP virtual machine? 37

5 A. Install XenServer Tools on the virtual machine. B. Suspend and then migrate the virtual machine. C. Enable multipathing on the virtual machine hard drive. D. Place the virtual machine on shared Fibre Channel or iscsi storage repository. QUESTION: 117 An administrator of a Provisioning services environment notices that several of the target devices that are configured to use a vdisk on the provisioning server are randomly failing to start and shut down. What should the administrator check to prevent this issue from occurring? A. The SOAP Service is running. B. High availability is enabled on the vdisks. C. The target devices are configured to start up from hard disk. D. All network switch ports have spanning tree protocol disabled. Answer: D QUESTION: 118 Scenario: An administrator is troubleshooting a Provisioning services environment. After the administrator configured a new version of the vdisk for 10 identical target devices all running on the same XenServer host, the administrator discovers that only the first target device started with the new vdisk configured. The other nine target devices failed to startup. What is one of the steps the administrator should take to resolve this issue? A. Configure the PXE Service. B. Configure the bootstrap file. C. Restart the Stream Service. D. Change the vdisk access mode. Answer: D QUESTION: 119 Scenario: An administrator is troubleshooting a Provisioning services farm that consists of two identical servers and 100 identical target devices. From the Provisioning Services Console the administrator notices that one of the provisioning servers has twice the amount of target devices connected compared with the other provisioning server. The 38

6 vdisk used and the provisioning servers are configured to use high availability and load balancing. What should the administrator check to correct load balancing? A. Power Rating B. Bootstrap options C. vdisk access mode D. Offline database support QUESTION: 120 Scenario: A virtual machine that uses Provisioning services is accidentally deleted by an administrator. The administrator creates a new virtual machine from the same template that was used to create the virtual machine deleted. However, the virtual machine is NOT able to start up from the vdisk. What must the administrator do to resolve the issue? A. Assign the correct vdisk to the target device. B. Reconfigure the target device MAC address. C. Configure the target device to start up from vdisk. D. Create a target device for the new virtual machine. Answer: B 39
