Hmm, I'm not sure about B. Putting a port in loopback could definitely affect customer data flow, unless they've got some kind of magic loopback mode. Time to consult the networking genie!

As an IT technician, I can confirm that Option E is true. Mirroring will still work while in loopback mode. It's like having a virtual mirror ball - just don't try to disco dance with it!

C) Both ports must rediscover the OAM capabilities of each other once the port is put back into service.

Interesting question! I'll go with A, C, and F. Rediscovering the OAM capabilities is crucial when the port comes back online.

I agree with A and F too. The loopback control PDU should direct the remote port to enter loopback mode, and only the OAM frames should be allowed through.

C and D are true because both ports need to rediscover each other's capabilities and continue sending Information PDUs to avoid going back to discovery mode.

Option A and F sound right to me. Looping back all packets except the OAM frames makes sense for troubleshooting purposes.

That's correct! Looping back all packets except for OAM frames is indeed useful for troubleshooting.
