Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The show interface command output primarily reveals issues at the Data Link layer (Layer 2) of the OSI model, as it displays information about interface status, CRC errors, framing errors, and collisions - all Layer 2 phenomena. Physical layer issues would show as line down or excessive carrier transitions. Network layer problems would be visible in routing tables and IP-specific commands. Transport and Application layer issues require different diagnostic commands.
