I’m confused about the MAC route for MAC-OI; I thought it was related to VPLS 2, not VPLS 20.

Vincent 1 year ago

I practiced a question similar to this where PE3 signaled a service label, so I feel like option C could be correct.

Lemuel 1 year ago

I remember something about PE3 and IMET routes, but I can't recall if it advertises them when the mesh-SDP is UP.

I think the flooding list for VPLS 20 might be important, but I'm not sure if it really only has three entries.

This question is testing my VPLS knowledge. I'll need to review the key VPLS mechanisms and try to eliminate the incorrect options.

I've studied VPLS pretty extensively, so I'm feeling confident I can identify the correct statement about the VPLS 20 operation.

Nicolette 1 year ago

I'm a bit unsure about this one. The VPLS terminology and behavior can be confusing, but I'll give it my best shot.

Okay, let me take a closer look at the exhibit and the question. I think I can figure this out if I focus on the key VPLS concepts.

Hmm, this looks like a tricky VPLS question. I'll need to carefully read through the options and think about the VPLS operation details.

This looks like a straightforward question about relationship types in a two-step approval process. I think the answer is B - a look up relationship would be the appropriate choice to establish the connection between the hiring manager and the director.

I believe that's option B.
