   A storage administrator is provisioning storage for a new virtual desktop infrastructure (VDI) environment. The VDI team expects that the virtual desktops will initially use very little storage, but over time they will consume more capacity as users install applications. The administrator must balance the need to avoid over-provisioning physical capacity with the need to ensure that the desktops do not experience performance degradation when they grow. The array supports thin provisioning, compression, and thick devices. Which approach should the administrator take?

   • AUse thin devices without compression, and rely on the array's automatic capacity management
   • BUse thin devices with compression enabled, and monitor allocated capacity closely
   • CUse thick devices to guarantee performance, and accept the higher upfront capacity cost
   • DUse a mix of thin and thick devices, with thin for the OS and thick for user data

   A storage administrator needs to increase the capacity of a thick device that is part of a storage group presented to a production host. The host is running a critical application that cannot be stopped. What should the administrator do?

   • AConvert the thick device to a thin device and then expand it
   • BDelete the device and recreate it with a larger capacity
   • CExpand the thick device online using the PowerMax management interface
   • DCreate a new thick device, add it to the storage group, and then migrate the data

   A storage administrator is monitoring a PowerMax array that is experiencing high latency on several devices. The administrator has checked the device-level metrics and found that the devices are not near their capacity limits. The administrator suspects that the issue is at the array level. Which additional metrics should the administrator examine?

   • AThe devices' WWNs to confirm they are correct
   • BThe devices' total capacity to see if they are too small
   • CFront-end port utilization and back-end port utilization
   • DThe devices' compression ratios to see if compression is causing overhead
