Actual exam question for Cisco's 300-420 exam

Question #: 82
Topic #: 5

Refer to the exhibit.

Refer to the exhibit. An engineer Is designing a multicampus Layer 3 Infrastructure using EIGRP as the routing protocol. The design must provide quick replies to queries In the event of a downlink, prevent unnecessary queries, and ensure that traffic does not unnecessarily transit the access layer. Which two actions must the engineer take for the network design? (Choose two.)

AConfigure core layer switches as stub routers.

BConfigure distribution layer switches to summarize routes to the core layer.

CConfigure access layer switches as stub routers.

DConfigure access layer and core layer switches as stub routers.

EConfigure access layer switches to summarize routes to the distribution layer.

Yes, that would help in ensuring traffic does not unnecessarily transit the access layer.

But shouldn't they also configure distribution layer switches to summarize routes to the core layer?

I think the engineer should configure access layer switches as stub routers.

Okay, so we're looking at B and either C or D as the right answers then. I'm leaning more towards D - configuring both the core and access as stub routers, that way we get the quick replies and no unnecessary transit no matter where the query originates.

Yes, with those configurations in place, the network should be able to meet the requirements effectively.

I think summarizing routes to the distribution layer may also help in achieving the desired network design.

Configuring the distribution layer switches to summarize routes to the core layer could be beneficial as well.

Yeah, I'm with you on that. Stub routing could definitely help prevent those unnecessary queries, and summarization at the distribution layer would keep the traffic from unnecessarily going through the access switches.

I agree, this is a tough one. I'm thinking the answer might involve configuring the distribution layer to summarize routes to the core, and either the core or access layer as stub routers.

Hmm, this question is tricky. I think the key is to understand the requirements - quick replies, preventing unnecessary queries, and no unnecessary transit through the access layer. That's a lot to consider.
