350-601 Storage Network Practice Question
Which TWO commands are used to verify Fibre Channel connectivity issues on a Cisco MDS switch? (Choose two.)
⚠ Common exam trap
Cisco often tests the distinction between Ethernet-based troubleshooting commands (like 'show ip interface brief' or 'show mac address-table') and Fibre Channel-specific commands, leading candidates to mistakenly apply familiar IP/Ethernet commands to a storage networking context.

Correct answer & explanation
✓
show interface fc <slot/port>
The 'show interface fc <slot/port>' command displays detailed status, errors, and operational state of a specific Fibre Channel interface, which is essential for diagnosing physical or link-level connectivity issues on a Cisco MDS switch. Option E is correct because the 'show flogi database' command lists all N-port (host) logins registered with the fabric via the Fabric Login (FLOGI) process, verifying that end devices have successfully established a session with the switch and are visible in the Fibre Channel fabric.
