Demo Questions

Question 1
In an IP datagram, which of the following fields identifies the receiving application?
  1. The protocol field of the transport layer header.
  2. The port field of the transport layer header.
  3. The protocol field of the network layer header.
  4. The port field of the network layer address.
Correct answer: B
Question 2
Static routing will be used in a network between a corporate head office, with many connected networks, and a branch office, with one connection to the head office. 
Which of the following best describes the likely configuration?
  1. The corporate head office router will have a default route and the branch site will have a more specific static route.
  2. The corporate head office router and the branch office router will both have specific static routes.
  3. The corporate head office router and the branch router will both have default routes.
  4. The corporate head office router will have a more specific static route and the branch office router will have a default route.
Correct answer: D
Question 3
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?
  1. traceroute 10.2.3.1
  2. traceroute 10.2.3.1 next-hop 10.1.2.1
  3. traceroute next-hop 10.1.2.1
  4. traceroute does not work on the Alcatel-Lucent 7750 SR.
  5. traceroute 10.1.2.1
Correct answer: A
Question 4
What is the default preference value for a static route in the Alcatel-Lucent 7750 SR?
  1. 0
  2. 5
  3. 10
  4. 15
Correct answer: B
Question 5
Which of the following statements apply to link state protocol behavior? Choose three answers.
  1. Routers broadcast the entire route table to all neighbors.
  2. Information about directly connected links is sent to all neighbors.
  3. An adjacency database is maintained by each router.
  4. The sequence number for an update is incremented as it is flooded from router to router.
  5. The topological database is the same for all routers in a single area.
Correct answer: BCE
Question 6
What causes an adjacency to change from down to two ways?
  1. When a link state update is received in response to a link state request.
  2. When a router receives a Hello packet that contains its own router ID in the neighbor list from a neighbor.
  3. When a router receives a database description packet from a neighbor.
  4. When a link state acknowledgement is received in response to a link state update.
Correct answer: B
Question 7
Click the exhibit button. 
  
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?
  1. Router R1 generates a type 4 LSA that is flooded to areas 0, 1, and 2.
  2. Router R3 generates a type 4 LSA that is flooded to areas 0, 1, and 2.
  3. Router R3 generates a type 4 LSA that is flooded to areas 0 and 2.
  4. 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 8
Which of the following commands can be used to display the number of SPF computations that have been performed on a router?
  1. show router ospf area <area-id>
  2. show router ospf neighbor
  3. show router ospf interface
  4. show router ospf status
Correct answer: A
Question 9
Click the exhibit button. 
  
In the topology shown, router R1 is an ASBR configured to export external routes to OSPF. How many type 4 LSAs will be present in the network?
  1. One.
  2. One for each of the routers in area 0
  3. One for each of the external routes exported by router R1.
  4. Type 4 LSAs are not generated in this network topology.
Correct answer: D
Question 10
Which of the following conditions will prevent an OSPF adjacency from reaching the full state? Choose three answers.
  1. MTU mismatch
  2. Incorrect subnet mask
  3. System interface not included in OSPF
  4. Area ID not the same
  5. Different metric set on each end of the link
  6. Router ID not defined
Correct answer: ABD
