350-601 Question #318: Real Exam Question with Answer & Explanation

Question

An engineer is performing a configuration on a Cisco Nexus 5000 Series Switch. The requirement is for the current Fibre Channel IDs in VSAN 120 to be saved across reboots. The Cisco environment also must integrate with a third-party solution that requires persistent Fibre Channel IDs for the VSAN. The WWN of the Cisco switch must be 33:e8:00:05:30:00:16:df and its Fibre Channel ID 0x070128. Which command set meets these requirements?

Options

• Afabric-binding database vsan 120
• Bysan 120 wwn 33:e8:00:05:30:00:16:df fcid 0x070128
• Cvsan 120 wwn 33:e8:00:05:30:00:16:df fcid 0x070128
• Dfcdomain fcid database

Explanation

{"question_number": 8, "question": "Which command set saves current FC IDs across reboots and integrates with third-party solutions requiring persistent FC IDs?", "correct_answer": "D", "explanation": "The 'fcdomain fcid database' command on Cisco MDS and Nexus switches is used to configure the FCID (Fibre Channel ID) persistence database. This command allows administrators to statically assign and preserve WWN-to-FCID mappings so that devices retain their FC IDs across switch reboots. This is essential for integration with third-party storage solutions that rely on consistent FC IDs. Option A (fabric-binding database) is for fabric binding/zoning, not FCID persistence. Options B and C contain the correct syntax for entries within the fcid database, but those sub-commands only work after entering 'fcdomain fcid database' configuration mode - making D the correct initiating command set.", "generated_by": "claude-sonnet", "llm_judge_score": 3}
