Which two statements are true about route summarization? (Choose two.)

Show Suggested Answer Hide Answer
Suggested Answer: A, B

Route summarization is a technique that reduces the number of routes that a router advertises to its neighbors by creating a single summary route that covers multiple subnets or networks. Route summarization has several benefits, such as:

It reduces the size of a routing table, which saves memory and CPU resources on the router. A smaller routing table also improves the lookup efficiency and convergence time of the routing protocol.

It reduces signaling, which means that less bandwidth is consumed by routing updates and less processing is required by neighboring routers. This also enhances the stability and scalability of the network, as fewer routing changes are propagated.

It improves route aggregation, which means that more specific routes are replaced by a less specific route that can be advertised to other autonomous systems or routing domains. This simplifies the inter-domain routing and hides the internal topology details.

Route summarization does not necessarily summarize the routing table entries into a default route, although a default route can be considered a special case of route summarization where all destinations are covered by one route. Route summarization also does not improve the best route calculation, as it may introduce suboptimal routing or black holes if not done properly.Reference:Introduction to Route Summarization - NetworkLessons.com,Route Summarization > Example for Understanding Route Summarization - Cisco Press

Wait, it actually reduces signaling? Didn't know that!

Haha, D is a good one. Route summarization has nothing to do with the best route calculation. That's just silly.

C is definitely not true. Route summarization doesn't create a default route, it aggregates multiple routes into a single entry.

D seems off to me; I thought summarization mainly focused on reducing entries, not improving route calculations.

I feel like C is incorrect since summarization doesn't create a default route, but I can't remember the exact details.

I'm not so sure about B, but it sounds familiar. I remember something about signaling being reduced in a similar practice question.

This is a tricky one. I'm not sure if route summarization actually improves the best route calculation. I'll have to think that through carefully before selecting my answers.

I'm feeling confident about this one. Route summarization is all about aggregating routes to reduce the routing table, which should improve performance. I'll go with A and B.

Okay, I've got a strategy for this. I'll focus on the key effects of route summarization, like reducing table size and signaling. Then I can match those to the answer choices.

Hmm, I'm a bit unsure about the difference between route summarization and a default route. I'll need to review those concepts before attempting this.

This one seems pretty straightforward. I'd start by thinking about how route summarization can impact the routing table and signaling.
