Huawei Certified ICT Professional – Storage (HCIP-Storage) — Question 1

A service host is connected to a storage device through Fibre Channel SAN. However, the service host cannot detect mapped LUNs after scanning. Which of the following are possible causes?

Answer options

• A. The Fibre Channel module on the service host is faulty.
• B. No multipathing software is installed on the service host.
• C. Zones are incorrectly configured.
• D. The storage network is blocked by the firewall.

Correct answer: B

Explanation

The correct answer is B because without multipathing software, the service host may struggle to access the LUNs properly. While a faulty Fibre Channel module or misconfigured zones could cause issues, they do not directly explain the inability to detect LUNs as clearly as the absence of multipathing software does. Additionally, a blocked firewall would typically affect connectivity rather than LUN detection specifically.
