Cisco Cisco Certifications 352-011 Questions & Answers

• Question 171:

  Refer to the exhibit.

  

  A customer currently has a large EIGRP-based network with several remote sites attached. All remote sites connect to the two corporate data centers, depicted as 10.1.1.0 and 10.1.2.0. The customer has experienced several network-wide failures where neighbors were stuck-in-active and had other network stability issues due to some links flapping. Which two redesign options increase stability and reduce the load on the remote site routers, still maintaining optimal routing between remote sites and the two data centers? (Choose two)

  A. Set the data center routers as stub-routers

  B. Perform summarization at the data centers, selectively leaking routes sent to the remote sites

  C. Perform summarization at the remote sites, selectively leaking routes sent to the data centers

  D. Set the hello interval timer to be larger than the hold interval

  E. Increase the hold interval to accommodate lost hello packets on error-prone links

  Correct Answer: AB

• Question 172:

  You are designing an optical network. Your goal is to ensure that your design contains the highest degree of resiliency. In which two ways should you leverage a wavelength-switched optical network solution in your network design? (Choose two.)

  A. a wavelength-switched optical network guarantees restoration based strictly on the shortest path available

  B. a wavelength-switched optical network provides fault tolerance for single failures only

  C. a wavelength-switched optical network takes linear and nonlinear optical impairment calculation into account

  D. a wavelength-switched optical network assigns routing and wavelength information

  E. a wavelength-switched optical network eliminates the need for dispersion compensating units in a network

  Correct Answer: CD

• Question 173:

  What is a design aspect regarding multicast transport for MPLS Layer 3 VPNs using the Rosen Draft implementation?

  A. LDP is the multicast control plane protocol.

  B. Multicast traffic is forwarded over GRE tunnels.

  C. Multicast traffic is forwarded over LDP or RSVP signaled LSPs.

  D. Using the MDT SAFI in BGP ensures that PIM can be disabled in the core.

  Correct Answer: B

• Question 174:

  A financial trading organization plans to monitor the network latency for multicast data feeds on a hop-by-hop basis. Which technology should be added to their design to support this requirement?

  A. SPAN

  B. NBAR

  C. IPFIX

  D. Precision Time Protocol

  Correct Answer: D

• Question 175:

  Which two options are reasons for designing a large OSPF network with multiple areas connected to the backbone? (Choose two)

  A. Reduce the number of routes within an area

  B. Route tagging capability

  C. Simplify logical topology

  D. Enhance failure detection

  E. Reduce SPF algorithm runs

  Correct Answer: AE

• Question 176:

  Refer to the exhibit.

  

  You are designing MPLS-TE for this network. The links form Perth to Sydney and from Perth to Adelaide share the same optical fiber in one given segment. Which feature should you implement to eliminate the risk that a backup tunnel is installed over the same optical fiber as the primary one?

  A. Shared Risk Link Groups

  B. MPLS-TE Path Protection

  C. MPLS-TE auto-tunnel backup

  D. MPLS-TE Link protection

  Correct Answer: A

• Question 177:

  Which option is a critical mechanism to optimize convergence speed when using MPLS FRR?

  A. IGP timers

  B. Bandwidth reservation

  C. Shared risk link groups

  D. Down detection

  Correct Answer: D

• Question 178:

  Refer to the exhibit.

  

  This network is running IS-IS as the single routing protocol and the LSP and SPF timers are aggressively configured so the network converges in subsecond. The customer reports that router B had a memory crash and reloaded. Which resulted in some packets from the application being lost. The application servers are behind router G and the end users are behind router H, which design change should be made to prevent this packet-loss problem from reoccurring?

  A. Use asymmetric carrier delay timer

  B. Deploy all links as point-to-point

  C. Redesign the network as a flat level 2

  D. Optimize the LSP/SPF timers to send LSPs immediately after a topology change

  E. Enable the advertisement of the overload bit for a specific amount of time after reload on router B

  Correct Answer: E

• Question 179:

  Refer to the exhibit.

  

  Which solution must be used to send traffic from the foreign wireless LAN controller to the anchor wireless LAN controller?

  A. Encapsulate packets into an EoIP tunnel and send them to the anchor controller

  B. Send packets from the foreign controller to the anchor controller via Layer 3 MPLS VPN or VRF-Lite

  C. Send packets from the foreign controller to the anchor controller via IPinIP or IPsec tunnel

  D. Send packets without encapsulation to the anchor controller over the routed network

  Correct Answer: A

• Question 180:

  A network engineer has been tasked to design an IPV6 wireless sensor network using IEEE 802.15 4 to support an for prefect .Which two protocols does the engineer need to utilize for this design? (Choose two)

  A. 802 11

  B. VPN

  C. 6LOWPAN

  D. 802 11ax

  E. 802 11ac

  Correct Answer: CD
