   An administrator is troubleshooting a performance issue on a PowerStore array. The array shows high read latency on a specific volume, but the host reports acceptable application response times. What is the most likely explanation for this discrepancy?

   • AThe host is caching reads, so it is not sending all read requests to the array
   • BThe host is using a storage tier that is faster than the array's reported metrics
   • CThe array is reporting latency in milliseconds while the host reports in microseconds
   • DThe array metrics include time spent in the host's I/O queue

   An administrator is monitoring a PowerStore array and notices that the 'Total Writes' metric is significantly higher than the 'Total Reads'. The array is used for a database application. What does this metric imbalance most likely indicate?

   • AThe host is using a read cache that is serving most read requests
   • BThe database is performing a large number of write operations, such as transaction logs or data inserts
   • CThe array is experiencing a hardware failure
   • DThe array is configured with an incorrect RAID level

   An administrator is using PowerStore Manager to monitor the array. They notice that the 'Frontend Port' metrics show high utilization on one port but low utilization on others. What is the most likely cause of this imbalance?

   • AThe hosts are not using multipathing correctly
   • BThe array is configured with an incorrect RAID level
   • CThe array is performing a firmware upgrade
   • DThe storage pool is too small

   A company has a PowerStore array with two storage pools: Pool A (using fast SSD) and Pool B (using slower HDD). A critical volume is currently in Pool A, but the administrator is considering moving it to Pool B to free up space in Pool A. The volume has a latency-sensitive workload. What should the administrator do before making the move?

   • AIncrease the volume's SLO before moving it
   • BMove the volume and monitor the latency for a week
   • CMove the volume and immediately check the latency
   • DCheck the volume's current latency and IOPS, then estimate the expected latency on Pool B based on its performance characteristics
