Cisco Cisco Certifications 352-001 Questions & Answers

• Question 471:

  Which two IPv6 integration technologies support IPv6 multicast? (Choose two.)

  A. 6VPE

  B. 6PE

  C. dual stack

  D. ISATAP

  E. 6to4

  Correct Answer: CF

• Question 472:

  Cyclic congestion spikes are causing your Telnet users to experience delays. Traffic analysis shows minimal use of UDP. Which technology can you deploy to mitigate the problem?

  A. Committed Access Rate

  B. Weighted RED

  C. Deficit Round Robin

  D. Class Based Weighted Fair Queuing

  Correct Answer: B

• Question 473:

  Refer to the exhibit.

  

  A customer runs OSPF with Area 5 between its aggregation router and an internal router.

  When a network change occurs in the backbone, Area 5 starts having connectivity issues due to the SPF algorithm recalculating an abnormal number of times in Area 5. You are tasked to redesign this network to increase resiliency on the customer network with the caveat that Router B does not support the stub area. How can you accomplish this task?

  A. Set Area 5 to stubby at the ABR anyway.

  B. Increase the bandwidth on the connection between Router A and Router B.

  C. Turn on LSA throttling on all devices in Area 5.

  D. Implement LSA filtering on the ABR, allowing summary routes and preventing more specific routes into Area 5.

  E. Create a virtual link to Area 0 from Router B to the ABR.

  Correct Answer: D

• Question 474:

  A Mobile Service Provider would like to design and deploy an Ethernet service which has similar physical link failover/failback characteristics on the active/backup links as the APS/MSP SONET properties. Which Layer 2 services should be considered to address this design feature?

  A. Port-Channel

  B. MLPPP

  C. Flex Link

  D. Ethernet Pseudowires

  Correct Answer: C

• Question 475:

  You are designing the QoS features for a large enterprise network that includes DMVPN. When would you need to configure QoS preclassify?

  A. when you are marking packets with the DSCP bits

  B. when you are marking packets with the TOS bits

  C. when your service provider requires the DSCP bits be set

  D. when the QoS policy cannot be based on DSCP ToS bits

  Correct Answer: D

• Question 476:

  On a VoIP solution design, which option shows one-way latency, packet loss, and jitter measurements that ensure acceptable voice quality?

  A. Latency: 110 ms Packet loss: 1% Jitter: 40 ms

  B. Latency: 130 ms Packet loss: 0.5% Jitter: 30 ms

  C. Latency: 150 ms Packet loss: 1.25% Jitter: 20 ms

  D. Latency: 170 ms Packet loss: 0.75% Jitter: 10 ms

  Correct Answer: B

• Question 477:

  Which statement about OSPF incremental SPF is true?

  A. iSPF must be enabled on all routers in the domain.

  B. iSPF must be enabled on all routers in a particular area.

  C. iSPF capability is advertised using Opaque LSAs.

  D. iSPF is local to the router and does not require interoperability.

  E. iSPF is negotiated during the OSPF adjacency process.

  Correct Answer: D

• Question 478:

  A certain service provider offers RFC 2547-based L3VPN service. The service provider is using OSPF to carry infrastructure routes and MP-BGP to carry customer routes. It has also deployed a full mesh of Cisco MPLS TE tunnels with FRR for link and node protection. OSPF and BGP have not been tuned for faster convergence.

  Which three types of failure does Cisco MPLS TE FRR address in this service provider's network? (Choose three.)

  A. P (core) node failure

  B. PE node failure

  C. PE-P link failure

  D. P-P link failure

  E. PE-CE link failure

  Correct Answer: ACD

• Question 479:

  A service provider is offering a QoS-based transport service. Three classes have been defined in the core, including an Expedited Forwarding (EF) class for VoIP traffic. Which tool should be used at the ingress for the EF class?

  A. policing

  B. shaping

  C. WRED

  D. CB-WFQ

  Correct Answer: A

• Question 480:

  When developing an MVPN design, which performance and scalability consideration must be taken into account?

  A. CE end-to-end PIM adjacency establishment

  B. multicast data sent to all PE routers on the default MDT

  C. RP placement in the multicast VRF

  D. RP placement in the customer network

  Correct Answer: B
