Cisco 352-001 Online Questions & Answers

• Question 221:

  You are working on a network design for Customer A. This design should consider fast convergence features, and it was agreed that BFD should be used for faster link-transition detection. Which three options apply to the use of the echo function in BFD? (Choose three.)

  A. It can be used with asynchronous mode.
  B. BFD control packets are not required.
  C. It can be enabled individually in each direction.
  D. It has the advantage of testing the forwarding path on the remote system.
  E. The rate of periodic transmission of BFD control packets should be increased.
  A. It can be used with asynchronous mode.
  C. It can be enabled individually in each direction.
  D. It has the advantage of testing the forwarding path on the remote system.

• Question 222:

  Which of these can you use to effectively and dynamically reduce IP address spoofing?

  A. Egress Packet Filtering
  B. Ingress Packet Filtering
  C. Egress Route Filtering D. route dampening
  E. unicast Reverse Path Forwarding
  E. unicast Reverse Path Forwarding

• Question 223:

  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 hostswill 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.
  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.

• Question 224:

  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
  B. Enable netFlow on central data center routers

• Question 225:

  When you design a network, when would it be required to leak routes into a Level 1 area?

  A. when a multicast RP is configured in the nonbackbone area
  B. when MPLS L3VPN PE devices are configured in the Level 1 areas
  C. when equal cost load balancing is required between the backbone and nonbackbone areas
  D. when unequal cost load balancing is required between the backbone and nonbackbone areas
  B. when MPLS L3VPN PE devices are configured in the Level 1 areas

• Question 226:

  What are two reasons for instrumenting your network and network devices to collect performance data? (Choose two.)

  A. to determine the impact of jitter and latency on application performance
  B. to enable capacity planning decisions
  C. to route traffic around constrained choke points in the network
  D. to determine the locations at which QoS needs to be implemented
  B. to enable capacity planning decisions
  D. to determine the locations at which QoS needs to be implemented

• Question 227:

  Which technique can be used to deploy IPv6 services in an IPv4-only routed backbone network?

  A. NAT64 at the peering locations
  B. 6PE in the backbone network
  C. 6RD on CE routers and 6RD border relays at the peering locations
  D. dual-stack lite and NAT44 at the peering locations
  C. 6RD on CE routers and 6RD border relays at the peering locations

• Question 228:

  B. millisecond LMI timers
  C. A-bit signaling
  D. Frame BFD Lite
  E. section 9 LMI convergence
  A. asynchronous LMI
  C. A-bit signaling
