QUESTION 221
When considering the design of the E-Commerce topology which of the following are true?

A.    One-armed SLB design with multiple security contexts removes the need for a separate firewall in
the core layer

requiring no security between the web, application, and database zones
C.    One-armed SLB design with two firewall layers ensures that non load-balanced traffic still traverses the ACE so that the health and performance of the servers is still being monitored

QUESTION 227

C.    In multicast routing, the source of a packet is known.

E.    Multicast routing is much like unicast routing, with the only difference being that it has a a group of receivers rather than just one destination

Answer: AC

QUESTION 228
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

Answer: D

QUESTION 229
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
B.    Avoid bandwidth starvation due to video traffic by preventing and controlling the wide adoption
of unsupported video applications
C.    Which traffic model is in use, the flow direction for the traffic streams between the application
components, and the traffic trends for each video application
D.    Streaming video applications are sensitive to delay while interactive video applications, using
TCP as the underlying transport, are fairly tolerant of delay and jitter
