Which of the following is a result when designing multiple EIGRP autonomous systems within the Enterprise Campus network?

Which of the following is a result when designing multiple EIGRP autonomous systems within the Enterprise Campus network?
A . Improves scalability by dividing the network using summary routes at AS boundaries
B . Decreases complexity since EIGRP redistribution is automatically handled in the background
C . Reduces the volume of EIGRP queries by limiting them to one EIGRP AS
D . Scaling is improved when a unique AS is run at the Access, Distribution, and Core layers of the network

Answer: A

Explanation:

Chapter 2 of CiscoPress CCDP fourth edition clearly says (there is even a test at the end of the chapter) that introducing additional ASes won’t reduce the volume of EIGRP queries as these will be forwarded across the ASes.
