• Question 106:

  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

• Question 107:

  Which of the following should the Enterprise Campus network designer consider with respect to Video traffic?

  A. While it is expected that the sum of all forms of video traffic will grow to over 90% by 2013, the Enterprise will be spared this rapid adoption of video by consumers through a traditional top-down approach
