Cisco Exam 300-510 Topic 10 Question 67 Discussion

Actual exam question for Cisco's 300-510 exam

Question #: 67
Topic #: 10

Refer to the exhibit.

A service provider is running IS-IS in the core, and all routers use the default IS-IS configuration and reside in the same are

a. All routers maintain a different 6 bytes for the system ID. but the attached bits in the NET are the same. After an engineer added router R6 to the network. R3 and R5 began to experience CPU processing issues. Which action must the engineer take to resolve the issue?

AConfigure all routers lo operate as IS-IS Level 1 routers by altering the attached bit to ensure that a default route is Injected Into the routing tables.

BConfigure R6 to operate as a Level 1 router only so that it maintains the Level 1 database for all routers.

CConfigure routers R5 and R3 to operate as Level 1 routers only so that they inject a default routing into the routing tables of the other routers

DConfigure all routers to operate as IS-IS Level 2 routers so that only a Level 2 database is maintained.

Option D... so, we're just gonna make everything Level 2 and call it a day? Sounds like a real 'nuke it from orbit' kind of approach. I dig it!

But wouldn't that be a bit drastic? Maybe there's a more targeted solution.

Yeah, sometimes you just gotta go with the 'nuke it from orbit' approach.

I'm just picturing the engineer adding R6 and then hearing the distant screams of R3 and R5 as their CPUs start melting down. Yikes!

Hold on, are we sure the problem is with the attached bits? What if the issue is actually with the default route injection? Maybe Option C is the solution here.

Option B looks like the way to go. Keeping R6 as a Level 1 router should prevent the CPU issues on R3 and R5. Sounds like a simple fix.

I agree, configuring R6 as a Level 1 router should help with the CPU issues on R3 and R5.

Hmm, this question seems tricky. I think the key here is to understand the impact of adding a new router to an IS-IS network. Gotta be careful with those attached bits!

User2: No, I believe we should configure R6 to operate as a Level 1 router only.

User1: I think we need to configure all routers to operate as IS-IS Level 2 routers.

But wouldn't configuring R6 to operate as a Level 1 router only also help resolve the CPU processing issues?
