Cisco Cisco Certifications 352-001 Questions & Answers

• Question 361:

  A. It is not recommended on BGP route reflectors.

  B. It only affects the use of the respective node as a transit node, and networks advertised within the LSPs of the node are still reachable.

  C. It can be set on a router during the startup process for a fixed period of time.

  D. It forces the midpoint MPLS-TE node to reoptimize the primary tunnels going through the OL node.

  E. It can be set on a router until other interacting protocols have signaled convergence.

  Correct Answer: BCE

• Question 362:

  Which statement is correct about policy-based routing?

  A. It can create microloops during network reconvergence.

  B. It should be implemented at both ends of a GRE tunnel.

  C. It can limit the network scalability.

  D. It decreases failure detection time.

  Correct Answer: A

• Question 363:

  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.

  Correct Answer: ACD

• Question 364:

  Which three techniques can be used to provide IPv6 first-hop security to prevent man-in- the-middle attacks? (Choose three.)

  A. DHCP snooping

  B. Dynamic ARP Inspection

  C. RA Guard

  D. ND Inspection

  E. BPDU guard

  F. IPv6 provider-independent address space

  Correct Answer: ACD

• Question 365:

  Refer to the exhibit.

  

  This OSPF network has just been deployed with four areas, but the hub-and-spoke area frequently flaps.

  You must fix this design failure. Which two reasons describe why the implementation of link-state summarization will minimize the effect of the instability in this network? (Choose two.)

  A. It lowers CPU utilization on ABR routers.

  B. It allows for a more scalable network.

  C. It separates the data center area from the hub-and-spoke area.

  D. It runs a partial SPF on the campus area when any link of the hub-and-spoke flaps.

  E. It minimizes the number of prefixes that are advertised to other areas.

  Correct Answer: CD

• Question 366:

  To improve the stability of a global network, you have been tasked with changing the design to include link-state topology summarization. What are two issues that you should address as part of the design? (Choose two.)

  A. slow convergence

  B. suboptimal routing

  C. traffic black-holing

  D. packet reordering

  Correct Answer: BC

• Question 367:

  What should be taken into consideration when designing IPsec networks using Authentication Header (AH)?

  A. NAT

  B. transform set

  C. crypto maps

  D. ISAKMP

  Correct Answer: A

• Question 368:

  Refer to the exhibit.

  

  You are asked to design this OSPF network to converge within 60 ms for unicast packets after a topology change due to a single link failure. Which technology can be enabled while conforming to the design requirements?

  A. Loop-Free Alternates

  B. BFD

  C. IGP neighbor timer tuning

  D. IGP SPF timer tuning

  E. RSVP-TE Fast Reroute

  Correct Answer: B

• Question 369:

  Which two factors can significantly affect the OSPF network convergence time? (Choose two.)

  A. the tuning of OSPF LSA timers

  B. the number of OSPF routes

  C. the diameter of the OSPF network

  D. different processor capabilities of devices

  Correct Answer: AD

• Question 370:

  Which two statements describe how including Cisco IPoDWDM proactive protection in an optical design would minimize packet loss in the event of a fiber cut? (Choose two).

  A. It uses the FEC field on the OTN frame to trigger protection.

  B. It uses a "not to exceed" predefined BER threshold to cause traffic redirection.

  C. It reroutes the optical circuit after an event that impacts service.

  D. It is effective both when you have redundant and nonredundant Layer 3 MPLS paths.

  Correct Answer: AB
