FlashArray Implementation Specialist
FINAL REVIEW SCRIPT 2026 TESTED
ANSWERS GRADED A+
● Authorization Failure after adding DNS. Answer: The IP address
● Equivalent of DNS in FC switches. Answer: FC switches have their
own equivalent, but it is not the same as DNS in an IP sense.
● Command to display IO sizes for workloads. Answer: purevol
monitor --size
● Command to display latency for workloads. Answer: purevol monitor
--latency
● Command to display hosts, WWNs, and IO count. Answer: purehost
monitor --balance
● SAN Time. Answer: Latency outside the array, on the SAN. It means
the array is waiting for a request to arrive.
● High SAN Time. Answer: Issue with customer network
, ● Queue Time. Answer: How long IO waits to be queued and processed
once it arrives at the array.
● Causes of high queue time. Answer: Sustained large workloads,
Bursts of IO, Temporary buffer depletion
● Ready Latency. Answer: Time taken to read from the flash modules
and complete the request.
● Total Latency. Answer: Sum of all other latency components.
● Benefits of Data-Reduced Optimized Snaps and Copies. Answer:
Instant snapshot creation, No reservations, quiescing, or downtime
required, Crash-consistent data protection, Thousands of snapshots with
no performance impact.
● FlashArray snapshots immutability and unmountability. Answer:
Ransomware protection & SafeMode operations, Source dataset is
always full & protected, Copies have no dependency on the source
volume.
● FlashArray snapshots space consumption. Answer: They consume
zero space until data in the source volume is changed.
