• Question 441:

  A company wants a design that would support OSPF through a service provider ATM network. Which two OSPF network types should the designer use to establish OSPF neighborship between OSPF routers through the ATM network? (Choose two.)

  A. A broadcast network will always work through ATM networks.

  B. A broadcast network will work when the broadcast support is explicitly configured at the ATM network.

  C. Explicit neighbor statements are required when a nonbroadcast network is configured.

  D. Explicit neighbor statements are required when a point-to-multipoint network is configured.

  E. A nonbroadcast network does not require DR selection.

  Correct Answer: BC

• Question 442:

  A network designer wants to improve a company network design due to multiple network crashes. Which technology would allow for the restore of a network connection without informing the Layer 3 protocol?

  A. Bidirectional Forwarding Detection

  B. automatic protection switching

  C. UniDirectional Link Detection

  D. Ethernet OAM

  Correct Answer: B

• Question 443:

  Refer to the exhibit.

  

  You must ensure that both core A and core B devices have only the minimum information required for reaching the spoke routers yet maintain full reachability during network failures. Which of the following design solutions accomplishes these requirements?

  A. Route summarization, with specific route leaking on hubs A and B

  B. Route summarization, with GRE tunnel on hubs A and B

  C. Implement PfR enhancements on hubs A and B

  D. Implement ODR for hub-to-spoke routing

  Correct Answer: B

• Question 444:

  Company A has grown nationwide in the U.S., and each new remote branch has a Metro Ethernet circuit provisioned back to the data center at the headquarters on the West Coast. The operations team says that it cannot manage hundreds of circuits as the company continues to grow. You review the topology and notice that many of the branches are close to each other in geographical zones. How can you redesign this network to improve manageability and increase scalability?

  A. Add an aggregation layer router in each geographical zone.

  B. Add a redundant data center on the East Coast to serve some of the traffic there.

  C. Add a default route in each branch toward the data center on the West Coast.

  D. Use Optimized Edge Routing at the data center.

  E. Build an overlay MPLS network with Layer 3 VPN.

  Correct Answer: A

• Question 445:

  You are designing a network that includes IP QoS. Which two architectures could be used to ensure that IP QoS is implemented properly? (Choose two.)

  A. Differentiated Services, where the user, with the assistance of the RSVP signaling protocol, reserves the resources end to end before sending the data

  B. Integrated Services, where the user, with the assistance of the RSVP signaling protocol, reserves the resources end to end before sending the data

  C. Integrated Services, which relies on the information carried within each packet to make resource-allocation decisions at each network node

  D. Differentiated Services, which relies on the information carried within each packet to make resource allocation decisions at each network node

  E. Integrated Services, where the user, with the assistance of the DSCP signaling protocol, reserves the resources end to end before sending the data

  Correct Answer: BD

• Question 446:

  Refer to the exhibit.

  

  Which configuration change would maximize the efficiency of both the routing design and data forwarding plane in this topology?

  A. configure Router B to advertise the more specific prefixes instead of the aggregate

  B. configure Router B to advertise the more specific prefixes in addition to the aggregate

  C. configure Router B with a static route for the aggregate to Null0

  D. configure Router A to advertise 10.0.0.0/8 instead of the default route to Router B

  Correct Answer: C

• Question 447:

  What are the two best reasons to build a flooding domain boundary in a link-state network? (Choose two.)

  A. to prevent the transmission of router-specific information between portions of the network

  B. to aggregate reachability information

  C. to increase the size of the Shortest Path First tree

  D. to segregate complex and rapidly changing portions of the network from one another

  E. to provide an administrative boundary between portions of the network

  Correct Answer: BD

• Question 448:

  How does an OSPF ABR prevent summary route information from being readvertised from an area into the network core (Area 0)?

  A. It uses poison reverse and split horizon.

  B. It compares the area number on the summary LSA to the local area.

  C. It only sends locally originated summaries to the backbone.

  D. It advertises only inter-area summaries to the backbone.

  Correct Answer: C

• Question 449:

  You are designing a large-scale DMVPN network with more than 500 spokes using EIGRP as the IGP protocol.

  Which design option eliminates potential tunnel down events on the spoke routers due to the holding time expiration?

  A. Increase the hold queue on the tunnel interface of the spoke routers.

  B. Increase the hold queue on the physical interface of the spoke routers.

  C. Increase the hold queue on the physical interface of the hub router.

  D. Increase the hold queue on the tunnel interface of the hub router.

  E. Apply QoS for pak_priority class.

  Correct Answer: D

• Question 450:

  You are designing an IPv4 any source multicast redundancy solution. Which technology ensures the quickest RP convergence?

  A. Auto-RP

  B. Embedded RP

  C. bootstrap router

  D. MSDP anycast RP

  Correct Answer: D
