Your boss, Ronald, does not seem to be able to grasp subnetting. He comes out of a management meeting and quietly asks you to help him with a subnetting issue.

What is the best subnet mask to use in this scenario?

255.255.248.0

255.255.0.0

Why is summarization so important to an efficient routed system?

It adds detail to the route tables of routers.

Summarization reduces the size of route tables, prevents route table instability due to flapping routes, and reduces the size of routing updates.

Summarization enforces router authentication, preventing spurious updates from excessively loading the route.

Summarization sends all subnets as classful networks, eliminating the overhead of transmitting the mask in routing updates.
