What are two reasons for creating multiple areas in OSPF? (Choose two.)

Ato reduce the convergence time

Bto increase the number of adjacencies in the backbone

Cto increase the size of the LSDB

Dto reduce LSA flooding across the network

Show Suggested Answer

Suggested Answer: A, D

Option A is correct. Creating multiple areas in OSPF can help to reduce the convergence time . This is because changes in one area do not affect other areas, so fewer routers need to run the SPF algorithm in response to a change.

Option D is correct. Creating multiple areas in OSPF can help to reduce Link State Advertisement (LSA) flooding across the network. This is because LSAs are not flooded out of their area of origin.

Isn't it risky to have too many areas though?

Wait, I thought more adjacencies were a good thing?

I definitely recall that reducing LSA flooding is important, but I’m a bit hazy on the second reason. Maybe it’s about managing adjacencies?

I practiced a question like this, and I think increasing the size of the LSDB was mentioned, but I’m not confident that’s a reason for multiple areas.

I'm not entirely sure, but I remember something about reducing convergence time being a benefit of multiple areas.

I think one reason for creating multiple areas in OSPF is to reduce LSA flooding across the network. That sounds familiar from my studies.

Hmm, this is a tricky one. I think the key is to understand the benefits of the OSPF area structure. I'm leaning towards A and D, but I want to double-check my understanding before submitting.

I'm a bit unsure about this one. I know OSPF uses areas, but I'm not totally clear on the specific reasons for having multiple areas. I'll have to review my notes and try to reason through the options.

Easy peasy! The correct answers are A and D - creating multiple areas reduces convergence time and LSA flooding across the network. Gotta love that OSPF area hierarchy!

Okay, let me think this through. I know OSPF uses areas to manage the size of the network, but I'm not sure of the specific reasons for creating multiple areas. I'll have to think about this one.

Hmm, this seems straightforward. I think the key is to focus on the reasons for creating multiple areas in OSPF, not just general OSPF concepts.
