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
