Cisco Cisco Certifications 352-001 Questions & Answers

• Question 451:

  Refer to the exhibit.

  

  On this MPLS-based network ring, links have failed between router A and router failures formed microloops while the network converged, when A forwarded traffic to B but B forwards it back to A. Which technology is the simplest solution to avoid microloops without enabling a new protocol in the network?

  A. TE Fast ReRoute

  B. IP Fast ReRoute

  C. Loop-Free Alternate

  D. Remote Loop-Free Alternate

  Correct Answer: D

• Question 452:

  A company supports IPv4 and IPv6 addresses, and they need to be able to support flow- based translations for ultiple IPv6 devices to a single IPv4 address. Which address family translation design solution should be recommended?

  A. stateful NAT-PT

  B. NAT-PT

  C. stateless NAT64

  D. stateful NAT64

  Correct Answer: D

• Question 453:

  Which three LSA types can each trigger a partial SPF? (Choose three.)

  A. type 1 LSA (Router Link Advertisements)

  B. type 2 LSA (Network Link Advertisements)

  C. type 3 LSA (ABR Summary Link Advertisements)

  D. type 4 LSA (ASBR Summary Link Advertisements)

  E. type 5 LSA (Autonomous System External Link Advertisements)

  Correct Answer: CDE

• Question 454:

  You are designing a multisite VPN solution for a customer and you are concerned with the additional overhead of point-to-point tunnels and the associated overlay routing with DMVPN. How does a GDOI-based VPN eliminate the additional tunnel and routing overhead found in DMVPN?

  A. The GDOI-based VPN requires overlaying a secondary routing infrastructure through the tunnels.

  B. In a GDOI-based VPN, all group members share a common security association.

  C. The GDOI-based VPN requires the provisioning of a complex connectivity mesh.

  D. The GDOI-based VPN leverages the routing protocol to find its peer for tunnel setup.

  Correct Answer: B

• Question 455:

  What is the best practice for tuning routing protocol hello and dead timers when deploying IGP non-stop forwarding (NSF)?

  A. The hello and dead timers should be tuned to allow NSF to continue forwarding after an initial failure detection.

  B. NSF-independent timers should be used so that routing protocol timers have no effect.

  C. The hello and dead timers should be tuned so the link failure is detected before NSF has the chance to react to the failure.

  D. The routing protocol hello and dead timers should be decreased to the minimum.

  Correct Answer: A

• Question 456:

  In an OSPF network, users in a particular OSPF non-backbone area are complaining about slow access speeds to a shared corporate resource in another OSPF area. Traceroutes show that theusers are taking a suboptimal default route to the destinations. Which solution will improve access speed?

  A. Make the area totally stubby so that the default can be followed along the best path.

  B. Create a virtual link between the areas so that traffic can shortcut directly between them.

  C. Implement policy routing to channel the traffic in the optimal direction.

  D. Leak specific summaries on the ABRs for the remote subnets in addition to the default.

  Correct Answer: D

• Question 457:

  Four routers running IS-IS are connected to a single Ethernet link. Then, a fifth router is connected, which has a priority higher than any of the other routers connected to the network. What will happen?

  A. The new router will become the DIS and cause a temporary disruption in traffic through the link.

  B. The new router will become the DIS without causing a temporary disruption in traffic through the link.

  C. The new router will not be elected DIS unless the current DIS fails.

  D. The new router will not be elected DIS unless it has the lowest NET ID.

  Correct Answer: B

• Question 458:

  Your customer asks you to assist with their traffic policy design. They want to guarantee a minimum amount of bandwidth to certain traffic classes. Which technique would you advise them to implement?

  A. Modular QoS CLI

  B. committed accessrRate

  C. policy-based routing

  D. traffic shaping

  Correct Answer: A

• Question 459:

  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

  Correct Answer: E

• Question 460:

  What are two potential effects of increasing the percentage of priority traffic? (Choose two.)

  A. can increase latency and jitter for priority traffic

  B. can increase latency and jitter for non-priority traffic

  C. makes it impossible to bound the impact that priority traffic will have on non-priority traffic

  D. must be avoided regardless of traffic patterns

  E. will not ever change the performance of non-priority traffic

  Correct Answer: AB
