Huawei Certified ICT Professional – Storage v5.5 (HCIP-Storage) — Question 17

When troubleshooting performance issues of flash storage based on the I/O path, an engineer first needs to analyze the CPU performance of controllers. Generally, Fibre Channel networking consumes more CPU resources than iSCSI networking, and random I/Os consume more CPU resources than sequential I/Os.

Answer options

Correct answer: A

Explanation

The statement is correct because Fibre Channel generally demands more CPU resources due to its protocol overhead compared to iSCSI. Additionally, random I/O operations typically require more processing power than sequential I/O, which is more predictable and efficient, thus confirming the validity of the statement.
