   • APowerShell with the Dell EMC Storage CLI
   • BWindows Performance Monitor
   • CDell OpenManage Essentials
   • DPowerStore Manager (Unisphere for PowerStore)

   A storage administrator notices that a PowerStore appliance is reporting high latency for a critical volume used by a database application. The administrator needs to determine whether the latency is caused by the storage array or by the host/application. Which two metrics should the administrator compare to isolate the source of the latency?

   • AVolume latency and array CPU utilization
   • BIOPS and throughput on the volume
   • CAverage read latency and average write latency on the volume
   • DArray-side latency and host-side latency (as reported by the OS or application)

   A storage administrator needs to be notified immediately when a PowerStore volume exceeds a certain latency threshold. Which mechanism should be used to set up this notification?

   • ASet a threshold in CloudIQ and enable email notifications
   • BCreate a performance policy in PowerStore Manager
   • CConfigure an SNMP trap for the latency metric
   • DUse the PSTCLI to run a script that checks latency every minute

   A company is using PowerStore for a virtual desktop infrastructure (VDI) environment. The administrator wants to monitor the performance of the array to ensure it can handle the boot storm that occurs when many users log in at the same time. Which metric is most important to monitor during this event?

   • AAverage latency
   • BStorage pool free space
   • CTotal IOPS
   • DCPU utilization

   An administrator is investigating a performance issue on a PowerStore array. The array shows high read latency, but the storage pool has ample free space and the CPU is not saturated. Which additional metric should the administrator check to determine if the issue is related to the physical disks?

   • AThe array's total IOPS
   • BThe array's write cache hit ratio
   • CThe disk utilization percentage
   • DThe volume's service level objective (SLO)
