C is definitely true. Dropped traffic is a big issue until it’s relearned.

A seems right to me. Without traffic, no relearning happens.

I vaguely recall that once a MAC is purged, traffic to that address gets dropped until it’s relearned, but I can't remember the exact command needed.

I’m a bit confused about the commands. Does the "oam mac-register" actually help with relearning, or is it just for registering?

I remember something about how purging a MAC address affects traffic, but I'm not sure if it drops packets until relearning happens.

I'm pretty confident I can get this one. The "oam mac-purge" command with "register" option just marks the MAC address for relearning, it doesn't actually remove it. So the key is understanding the different ways the MAC address can be relearned.

Okay, let me think this through. I need to focus on what happens after the MAC address is purged, and how it can be relearned. The answer choices seem to be giving me different options for that.
