Huawei H12-821_V1.0 Exam - Topic 4 Question 81 Discussion

Actual exam question for Huawei's H12-821_V1.0 exam

Question #: 81
Topic #: 4

BGP is generally applied to complex networks where routes change frequently. Frequent route flapping consumes a large number of bandwidth and CPU resources, and even affects the normal operation of the network. This is an unavoidable problem that cannot be solved in BGP.

ATRUE

BFALSE

Show Suggested Answer

Suggested Answer: B

BGP Route Flapping and Mitigation

While route flapping is a concern in large-scale networks, BGP employs mechanisms such as Route Dampening to mitigate its impact. Route dampening suppresses frequently flapping routes for a period of time to reduce resource consumption and network instability.

Therefore, it is incorrect to state that the issue cannot be resolved in BGP.

HCIP-Datacom-Core Reference

The mechanism of route dampening is detailed in the BGP optimization chapters.

I feel like we covered that BGP has mechanisms to deal with route flapping, so I would probably say FALSE, but I could be wrong.

I vaguely recall a practice question about BGP and route stability, but I can't remember if it said flapping was unavoidable. This is tricky!

I think we discussed in class that while BGP can struggle with flapping, there are some techniques to mitigate it. So, I might lean towards FALSE.

Route flapping can be a real pain, but I don't think it's completely unavoidable in BGP. I'm going to carefully consider the strategies I've learned and select "FALSE" for this one.

Hmm, this is a tricky one. I think the key is to really understand the nature of route flapping and how it impacts network performance. I'll need to think through some strategies to mitigate that.
