What is the correct command to verify a Linux host is using native multipath MPIO?

Question

Options

• Amultipath -n
• Bmultipath -m
• Cmultipath -l
• Dmultipath -p

• B

• C

• D

Explanation

multipath -l displays the current multipath topology, showing all multipath maps, their paths, path groups, and device states - making it the correct command to verify that native MPIO multipath is active and functioning on a Linux host.

Why the distractors are wrong:

• A. -n - Not a recognized standard option for the multipath command; it is not documented and will produce an error.
• B. -m - Also not a valid standalone multipath flag for listing or verification purposes.
• D. -p - Sets the path grouping policy (e.g., failover, multibus) rather than displaying multipath status; it's a configuration flag, not a verification flag.

Memory tip: Think "-l for Look" - just like ls lists files, multipath -l lists your multipath devices so you can see what's there. If you need even more detail, multipath -ll pulls from all available sources including sysfs.
