AWS Certified Advanced Networking – Specialty (ANS-C00) — Question 126

You have 99 routes in your dynamic BGP propagated route table and you wish to add 2 more: 10.1.0.0 and 10.3.0.0. You cannot modify or remove routes that have already been announced.
What should you do?

Answer options

• A. Summarize the two routes to combine them into one and advertise it.
• B. Just advertise them, the 100 route limit is a "soft limit" and will be expanded automatically.
• C. You cannot add these routes.
• D. Call AWS support to increase your route limit.

Correct answer: A

Explanation

The correct answer is A because summarizing the two routes allows you to stay within the route limit while still advertising the necessary traffic. Option B is incorrect since the 100 route limit is a hard limit in many cases and does not automatically expand. Option C is wrong as you can add routes by summarizing them, and Option D is unnecessary when summarization solves the issue.
