Cisco Cisco Certifications 352-001 Questions & Answers

• Question 651:

  Which mechanism should be added to a network design to identify unidirectional Spanning Tree Protocol failures through BPDU loss?

  A. UDLD

  B. loop guard

  C. BPDU guard?

  D. root guard

  Correct Answer: B

• Question 652:

  When a router running EIGRP considers alternate paths, which ones will it consider loop- free?

  A. ones in which the reported distance is equal to the feasible distance

  B. ones in which the reported distance is less than the feasible distance

  C. ones in which the feasible distance is the same as the best possible route

  D. ones in which the reported distance is the same as the metric of the best possible path

  Correct Answer: B

• Question 653:

  What is the primary requirement for deploying OSPF graceful restart on a router?

  A. Aggressive routing protocol hellos and keepalives must be running on the router.

  B. The adjacent router must support graceful restart helper mode.

  C. Some form of fast Layer 2 down detection must be enabled on the router.

  D. The adjacent routers must be enabled to forward traffic during the failure.

  Correct Answer: B

• Question 654:

  Which three statements about EIGRP route summarization are correct? (Choose three.)

  A. By default, all EIGRP routes are automatically summarized; all routes will be summarized unless the noauto summary command is configured.

  B. By default, EIGRP automatically summarizes internal routes, but only each time a major network boundary is crossed.

  C. EIGRP route summarization can reduce the query diameter to help prevent SIA problems.

  D. Summary routes are inserted in the routing table with a next hop of null 0 and a high administrative distance, to prevent black holing of traffic.

  E. The metric for each summarized route is inherited from the lowest metric of the component routes.

  Correct Answer: BCE

• Question 655:

  What are two benefits of following a structured hierarchical and modular design? (Choose two.)

  A. Each component can be designed independently for its role.

  B. Each component can be managed independently based on its role.

  C. Each component can be funded by different organizations based on its role.

  D. Each component can support multiple roles based on the requirements.

  E. Each component can provide redundancy for applications and services.

  Correct Answer: AB

• Question 656:

  You are designing a Group Encrypted Transport Virtual Private Network solution consisting of 30 group members. Which measure helps protect encrypted user traffic from replay attacks?

  A. counter-based anti-replay

  B. time-based anti-replay

  C. nonce payload

  D. RSA-encrypted nonce

  E. digital certificates

  Correct Answer: B

• Question 657:

  Your design client has requested that you ensure that the client devices are not dynamically configured with incorrect DNS information. When finalizing the network design, which security option must be configured on the switches?

  A. IGMP snooping

  B. DHCP snooping

  C. root guard

  D. DNS snooping

  Correct Answer: B

• Question 658:

  In a redesign of a multiple-area network, it is recommended that summarization is to be implemented. For redundancy requirements, summarization is done at multiple locations for each summary. Some customers now complain of higher latency and performance issues for a server hosted in the summarized area. What design issues should be considered when creating the summarization?

  A. Summarization adds CPU overhead on the routers sourcing the summarized advertisement.

  B. Summarization prevents the visibility of the metric to the component subnets.

  C. Summarization creates routing loops.

  D. Summarization causes packet loss when RPF is enabled.

  Correct Answer: B

• Question 659:

  What statement is true about designing a policy in which more than one class share a queue?

  A. It must be avoided under all circumstances.

  B. It will result in a negative class.

  C. It requires consideration of the performance targets of classes sharing the queue.

  D. It should be deployed throughout the network to simplify the design.

  Correct Answer: C

• Question 660:

  You have been hired to redesign a network due to issues with congestion. How will a router function if the QoS mechanism of congestion avoidance is integrated into the existing network design?

  A. the router handles the overflow of traffic by using FIFO

  B. the router handles the possible buildup of congestion by using WRED

  C. the router forces inbound and outbound traffic to stay within a defined profile by using rate limiting

  D. the router separates packets based on certain characteristics by using NBAR

  E. the router marks packets based on certain characteristics by using PBR

  Correct Answer: B
