I think LLDP frames are flooded for topology discovery, but I can't recall if that's specific to EX Series devices or all devices.

I remember LLDP is supposed to work on Layer 2, but I'm not entirely sure if that's the only place it operates.

I'm not too familiar with LLDP-MED, so I'm not sure about the power negotiation part. I'll have to review that before answering.

Okay, let me think this through. LLDP is for discovering network devices, while LLDP-MED is more focused on power management. I'll go with C.

Hmm, I think B might be correct too. I remember something about LLDP frames being flooded across a Layer 2 domain.

I'm a bit confused on the difference between LLDP and LLDP-MED. Do they both operate on Layer 2 interfaces?

I'm pretty sure the answer is C, since EX Series devices support LLDP-MED power negotiation.
