Suggested Answer: B

To check the status and link layer of InfiniBand interfaces, the ibstat command is used. For example:

ibstat -d mlx5_0

This command provides detailed information about the InfiniBand device, including its state (e.g., Active), physical state (e.g., LinkUp), and link layer (e.g., InfiniBand).

Hmm, I think B) ibstat -d mlx5_X is the right choice here. That should give me the InfiniBand interface status, including the link layer details.
