  In the topology shown, router R1 is an ASBR configured to export external routes to OSPF. Assuming that there are no stub networks, which of the following statements regarding type 4 LSA generation is true?

  A. Router R1 generates a type 4 LSA that is flooded to areas 0, 1, and 2.

  B. Router R3 generates a type 4 LSA that is flooded to areas 0, 1, and 2.

  C. Router R3 generates a type 4 LSA that is flooded to areas 0 and 2.

  D. Router R3 generates a type 4 LSA that is flooded to area 0, and router R6 generates a type 4 LSA that is flooded to area 2.

  Correct Answer: D

• Question 303:

  What causes an adjacency to change from down to two ways?

  A. When a link state update is received in response to a link state request.

  B. When a router receives a Hello packet that contains its own router ID in the neighbor list from a neighbor.

  C. When a router receives a database description packet from a neighbor.

  D. When a link state acknowledgement is received in response to a link state update.

  Correct Answer: B

• Question 304:

  What are the default Hello and Dead timer intervals for OSPF on the Alcatel-Lucent 7750 SR?

  A. 5 and 15 seconds

  B. 10 and 30 seconds

  C. 5 and 20 seconds

  D. 10 and 40 seconds

  Correct Answer: D

  What triggers convergence of the routing protocol when the link between switch 1 and switch 2 goes down?

  A. Convergence is triggered when the adjacency between routers R1 and R2 drops as a result of Hello timeouts. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged.

  B. Convergence is triggered when the physical interfaces between routers R1 and R2 go down. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged.

  C. Convergence will not be triggered because switches cannot run routing protocols between them.

  D. Convergence is triggered when the switches notify the routers about the link state information. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged

  E. Convergence is triggered when an LSA is sent from router R1 to router R2 to indicate that the link is down. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged.

  Correct Answer: A

• Question 306:

  What is the default preference value for a static route in the Alcatel-Lucent 7750 SR?

  A. 0

  B. 5

  C. 10

  D. 15

  Correct Answer: B

• Question 307:

  Which of the following statements apply to link state protocol behavior? Choose three answers.

  A. Routers broadcast the entire route table to all neighbors.

  B. Information about directly connected links is sent to all neighbors.

  C. An adjacency database is maintained by each router.

  D. The sequence number for an update is incremented as it is flooded from router to router.

  E. The topological database is the same for all routers in a single area.

  Correct Answer: BCE

  A static route is created on router R1 "using the "static-route 0.0.0.0/0 next-hop 10.3.3.2" command. What command can be used to test the static route on an Alcatel-Lucent 7750 SR?

  A. ping static 10.5.5.5

  B. ping static 0.0.0.0/0

  C. ping 10.5.5.5

  D. ping 0.0.0.0

  Correct Answer: C

• Question 309:

  There is an IP host with IP address 10.2.3.1. A static route is created, using the "configure router static-route 10.2.3.0/24 next-hop 10.1.2.1" command. What is the correct traceroute command to test this static route on an Alcatel-Lucent 7750 SR?

  A. traceroute 10.2.3.1

  B. traceroute 10.2.3.1 next-hop 10.1.2.1

  C. traceroute next-hop 10.1.2.1

  D. traceroute does not work on the Alcatel-Lucent 7750 SR.

  E. traceroute 10.1.2.1
