A.

Reconfigure QoS based on the IntServ model.

B.

Configure selective packet discard to drop noncritical network traffic.

C.

Implement higher-speed uplink interfaces.

D.

Bundle additional uplinks into logical EtherChannels.

A.

VSS

B.

VLAN

C.

VRF-Lite

D.

MEC

 

Correct Answer: C


 

 

QUESTION 4

The Cisco Nexus 1000V is intended to address which disadvantage of the VMware vSphere solution?

 

A.

Inability to deploy new functional servers without requiring physical changes on the network

B.

Complexity added by the requirement for an ESX host for each virtual machine

C.

Network administrators lack control of the access layer of the network

D.

To increase the number of physical infrastructure and the virtual machines that can be managed

 

Correct Answer: C

 

 

 

 

QUESTION 5

clip_image002

 

Correct Answer:

clip_image004

 

 

QUESTION 6

Which statement about the ToR design model is true?

 

A.

It can shorten cable runs and simplify rack connectivity.

B.

Each ToR switch must be individually managed.

C.

Multiple ToR switches can be interconnected to provide a loop-free spanning-tree infrastructure.

D.

It can connect servers that are located in separate racks.

 

Correct Answer: A

 

 

 

 

 

QUESTION 7

Distinct, physical redundancy within a network layer is a key characteristic that contributes to the high availability of the hierarchical network design. Which of the following is not an examples of this model?

 

A.

SAN extension with dual fabrics such as a yellow VSAN and a blue VSAN utilized via multipath software

B.

Redundant power supplies and hot-swappable fan trays in Aggregate switches

C.

A single SAN fabric with redundant uplinks and switches

D.

Servers using network adapter teaming software connected to dual-attached access switches

 

Correct Answer: C

 

 

QUESTION 8

Which of the following facts must be considered when designing for IP telephony within an Enterprise Campus network?

 

A.

Because the IP phone is a three-port switch, IP telephony extends the network edge, impacting the Distribution layer.

B.

Video and voice are alike in being bursty and bandwidth intensive, and thus impose requirements to be lossless, and have minimized delay and jitter.

C.

IP phones have no voice and data VLAN separation, so security policies must be based on upper layer traffic characteristics.

D.

Though multi-VLAN access ports are set to dot1q and carry more than two VLANs they are not trunk ports.

 

Correct Answer: D

 

 

QUESTION 9

Which technology can block ports to provide a loop-free topology and does not contain a port state named “listening?”

 

A.

VLAN

B.

RPVST+

C.

VSS

D.

STP

 

Correct Answer: B

 

 

QUESTION 10

What is one reason to implement Control Plane Policing?

 

A.

allow OSPF routing protocol to advertise routes

B.

protect the network device route processor from getting overloaded by rate limiting the incoming control plane packets

C.

allow network devices to generate and receive packets

D.

protect the data plane packets

 

Correct Answer: B
