QUESTION 91

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

 

Correct Answer: C

 

 

QUESTION 92

Which option must be included in the design when implementing a triangle looped access layer design?

 

A.

A first hop redundancy protocol.

B.

Single uplinks between access and distribution switches.

C.

Layer 2 links between access switches.

D.

Layer 3 links between distribution switches.

 

Correct Answer: A

 

 

QUESTION 93

Which unique characteristics of the Data Center Aggregation layer must be considered by an Enterprise Campus designer?

 

A.

Layer 3 routing between the Access and Aggregation layers facilitates the ability to span VLANs across multiple access switches, which is a requirement for many server virtualization and clustering technologies.

B.

“East-west” server-to-server traffic can travel between aggregation modules by way of the core, but backup and replication traffic typically remains within an aggregation module.

C.

Load balancing, firewall services, and other network services are commonly integrated by the use of service modules that are inserted in the aggregation switches.

D.

Virtualization tools allow a cost effective approach for redundancy in the network design by using two or four VDCs from the same physical switch.

 

Correct Answer: C

QUESTION 97

Which two protocol characteristics should be most considered when designing a single unified fabric for the Data Center? (Choose two.)

 

A.

FCIP or FCoE allow for easier integration by using the Fibre Channel Protocol (FCP) and Fibre Channel framing

B.

iSCSI uses a special EtherType and an additional header containing additional control information

C.

FCIP and iSCSI has higher overhead than FCoE owing to TCP/IP

D.

FCoE was initially developed to be used as a switch-to-switch protocol, while FCIP is primarily meant to be used as an access layer protocol to connect hosts and storage to a Fibre Channel SAN

E.

FCoE requires gateway functionality to integrate into an existing Fibre Channel network

 

Correct Answer: AC

What Nexus technology avoids blocking links between the access layer and the aggregation layer in a data center network design?

 

A.

FCoE

B.

LACP

C.

vPC

D.

FEX

 

Correct Answer: C
