QUESTION 20

Which of the following is most accurate with respect to designing high availability within the Enterprise Campus network?

 

A.

High availability at and between the Distribution and Access layers is as simple as redundant switches and redundant Layer 3 connections.

B.

Non-deterministic traffic patterns require a highly available modular topology design.

C.

Distribution layer high availability design includes redundant switches and Layer 3 equal-cost load sharing connections to the switched Access and routed Core layers, with a Layer 3 link between the Distribution switches to support summarization of routing information from the Distribution to the Core.

D.

Default gateway redundancy allows for the failure of a redundant Distribution switch without affecting endpoint connectivity.
