Your VPC has a DX connection that is advertising 99 routes. You have two more prefixes to add: 10.223.1.0/24 and 10.223.2.0/24. You have several locations, so you need to be as exact as possible with your routing.
How would you do this?

A. Add the prefixes; AWS allows for as many BGP routes as you need but not static.

B. Contact AWS to extend the number of prefixes you are allowed to advertise.

C. Summarize the routes into a 10.223.0.0/22 and advertise that route instead.

D. Summarize the routes into a 10.223.0.0/12 and advertise that route instead.








 

Suggested Answer: C



BGP has a strict 100 prefix limit. 10.223.0.0/12 includes both routes but is not very specific. 10.223.0.0/22 is the proper summarization of both routes.
