Cisco Cisco Certifications 352-011 Questions & Answers

• Question 31:

  A new video multicast application is deployed in the network. The application team wants to use the 239.0.0.1 multicast group to stream the video to users. They want to know if this choice will impact the existing multicast design. What impact will their choice have on the existing multicast design?

  A. Because 239.0.0.1 is a private multicast range, a flood of PIM packets that have to be processed by the CPU and hosts will be sent by the routers in the network.

  B. Because 239.0.0.1 is a private multicast range, the rendezvous point has to send out constant group updates that will have to be processed by the CPU and hosts.

  C. The multicast application sends too many packets into the network and the network infrastructure drops packets.

  D. The 239.0.0.1 group address maps to a system MAC address, and all multicast traffic will have to be sent to the CPU and flooded out all ports.

  Correct Answer: B

  You have been asked to design a high -density wireless network for a university campus. Which two principles would you apply in order to maximize the wireless network capacity? (Choose two.)

  A. Implement a four-channel design on 2.4 GHz to increase the number of available channels.

  B. Make use of the 5-GHz band to reduce the spectrum utilization on 2.4 GHz when dual- band clients are used.

  C. Choose a high minimum data rate to reduce the dory cycle.

  D. Enable 802.11n channel bonding both 2.4 GHz and 5 GHz to increase the aggregated cell throughput.

  E. Increase the number of SSIDs to load-balance the client traffic.

  Correct Answer: CE

• Question 36:

  A customer requests that you determine how much of their remote branch traffic into a central data center is related to a call manager that resides in the data center. Which solution do you recommend?

  A. Enable NetFLow on branch routers

  B. Enable netFlow on central data center routers

  C. Perform SNMP polling of central data center routers

  D. Perform SNMP polling of branch routers

  E. Create an ACL on the local call manager switch with logging enabled

  F. Span traffic from the switch port on the call manager to a data analyzer

  Correct Answer: B

• Question 37:

  Which statement about SDN framework environment is true?

  A. The control plane functions is split between a SDN controller and the networking element

  B. The data plane is pulled from the networking element and put in a SDN controller

  C. The data plane is controlled by a centralized SDN element

  D. The control plane is pulled from the networking element and put in a SDN controller

  E. The control plane and data plane is pulled from the networking element and put in a SDN controller and SDN agent

  Correct Answer: D

• Question 38:

  What is an implication of using route reflectors in an iBGP topology?

  A. Route reflection limits the total number of iBGP routers.

  B. Route reflection causes traffic to flow in a hub-and-spoke fashion.

  C. The manipulation of BGP attributes is not supported on the other routers than the route reflectors.

  D. Route reflectors can create routing loops when more than one router reflector is used in the same cluster.

  E. Multipath information is difficult to propagate in a route reflector topology.

  Correct Answer: E

• Question 39:

  Which two impacts of adding the Ip events dampening feature to a network design are true? (Choose two.)

  B. It reduce the utilization of system processing resources.

  C. It speeds up link failure detection.

  D. It protects against routing loops.

  E. it improves overall network stability.

  Correct Answer: BE
