R4 and R5 are definitely not in the path.

R1 can't be the MP since it's the PLR.

Wait, why wouldn't it be R3? Seems off.

Totally agree, R2 is the right answer!

The Merge Point is Router R2.

I recall that the Merge Point is where the traffic gets rejoined after a reroute. I think it could be R2, but I’m not entirely confident.

I practiced a similar question where R1 was also the PLR, and I chose R3 as the MP. I hope that’s still relevant here!

I think the Merge Point is Router R2, but I'm not completely sure. I remember something about it being the next hop after the PLR.

I’m a bit confused about the definitions. Is the Merge Point always the next router in the path? I feel like I need to double-check that.

Okay, let me think this through. The company wants to improve employee engagement by allowing them to create posts and share files in an interest group. That sounds like a social collaboration tool, so I'm guessing the answer is Yammer.

Based on the diagram, it seems like option B - router R1 switching to a secondary path - would be the quickest way to recover service. I'll mark that one down.
