• Question 57:

  In supporting a VDI environment, which are factors in estimating the number of boot I/Os required per virtual desktop?

  A. Data required to boot, boot time, I/O size

  B. Maximum disk IOPS, desktop RAM allocation, I/O size

  C. Hypervisor nodes in cluster, I/O size, desktop RAM allocation

  D. Data required to boot, boot time, maximum disk IOPS

  Correct Answer: A

• Question 58:

  You are implementing a VDI solution provided by the project Solutions Architect at a customer site. After application testing, the Storage Administrator states that the solution is spread across more disks than anticipated.

  What explains why the solution design requires more disks than initially planned?

  A. The design accounts for excessive boot I/O in case of an HA event.

  B. The original request was for thin provisioning, but VDI environments require thick provisioning.

  C. Best practice for VDI solutions is to use RAID 6, and this was not done.

  D. Best practice for VDI solutions is to use RAID 1/0, and this was not done.

  Correct Answer: A

• Question 59:

  A VDI environment is using VNX over iSCSI for its data stores. All planning trials with an application test harness, and thorough HA simulation, indicated a maximum of 1000 virtual desktops for the VNX pool for acceptable performance. The actual number of desktops allocated to the pool is 750.

  Users have reported poor virtual desktop performance, and the VNX Administrator has observed a

  consistently high level of read I/O on the VNX LUNs servicing this VDI solution.

  What is a possible cause of this situation?

  A. Desktops have insufficient RAM allocation.

  B. A desktop virus has triggered CAVA antivirus scan for all desktops.

  C. An employee shift change triggered excessive I/O to load user profiles.

  D. VNX FAST Cache was not sized correctly.

  Correct Answer: A

• Question 60:

  What drives the storage sizing requirements for VDI?

  A. desktop/drive density

  B. desktop/drive capacity

  C. desktop/drive type

  D. desktop/drive rpm

  Correct Answer: A
