Options A and E are the obvious choices here. I mean, who doesn't want to monitor and troubleshoot their point-to-point links and last-mile connections?

Haha, I bet the person who wrote this question is trying to trick us. 'Monitor and troubleshoot end-to-end services'? That's like asking a plumber to fix a broken TV!

I'm not sure about option C. Triggering MPLS protection at the core using the EFM standard doesn't sound right to me. Isn't that what BFD is for?

Option E is definitely correct. The EFM standard is all about the last-mile connection to the Service Provider, so that's a no-brainer.

I believe it should not be used at the core to trigger MPLS protection, BFD is the better method for that.
