I agree, Router B is the clear choice here!

Wait, are we sure about that? Default values can be tricky.

Definitely Router B, priority rules!

I thought it would be Router D since it has the highest IP.

Router B has the highest priority, so it should be DR.

I thought the default values for Alcatel-Lucent routers were lower than 10, so that might mean Router D won't be selected, but I need to double-check that.

If I recall correctly, the priority is the first factor, so Router B should definitely be the DR, but I might be mixing it up with another question we practiced.

I remember something about the highest IP address being a tiebreaker, but I can't recall if that applies here since Router B has a higher priority.

I think Router B should be the PIM DR since it has the highest priority of 100, but I'm not entirely sure how the default values for C and D come into play.

Got it, that makes sense. Router D with the highest IP address would be selected as the PIM DR on this multi-access network. I'm feeling pretty confident about this one.

I think the key here is the Alcatel-Lucent 7750 SRs being set to the default value. That means Router C and Router D are on equal footing in terms of priority. So the tiebreaker would be the highest IP address, which is Router D.

Okay, let's see. Router B has the highest priority at 100, so that seems like the obvious choice. But the question mentions Router D having the highest IP address, so I'm a bit confused.

Hmm, this looks like a tricky PIM DR priority question. I'll need to carefully consider the given information about the router configurations.

I'm a bit unsure about the last two options. I'll have to review my notes on the benefits of thick provisioning to decide which ones are true.

I think an external NAT IP address might be the problem, but I can't recall which option covers that. Maybe option B? It's tough to remember all these specifics under pressure!

This is a tricky one. I'm not sure if simply directing the other projects to use project A's plan is the best approach, as that might not fully address the needs of the other projects. Creating a program-level communications plan seems like it could be a more comprehensive solution.
