Option D is the correct answer. R3 should be a team player and update its database with the latest LSA from R2. Though, can we all just agree that routers should have a social media platform to coordinate their LSA updates? #RouterProblems

I agree, it would be so much easier if routers could just chat on a social media platform!

I'm going with D. R3 needs to keep its information up-to-date, and the higher sequence number indicates the LSA from R2 is the more recent one. Gotta stay on top of those link state changes, folks!

D seems like the way to go. R3 should update its database and share the latest information with its neighbors. Keeping up with the Joneses, or in this case, the Routers, is important in the networking world.

Hmm, this is a tricky one. I'm leaning towards B, but I'm not totally sure. Why can't routers just get along and share their LSAs without any drama, am I right?

I think the correct answer is D. R3 should install the LSA from R2 in its database, send an ACK, and flood it to its neighbors. The sequence number is higher than the one it received from R4, so it needs to update its information.
