Demo Questions

Question 1
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 2
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 3
Which of the following statements describe the major features of OSPF? Choose two answers.
  1. Fast reroute capability
  2. Control traffic prioritization
  3. Route redistribution
  4. Traffic engineering extensions
  5. Cut through forwarding
Correct answer: CD
Question 4
Click the exhibit button. 
  
What can you deduce from the show command on router R6?
  1. The router R6 interface is in a multi-access segment. It is neither the DR nor the BDR for the segment. The DR for this segment would be the router with router ID 10.10.10.5.
  2. The router R6 interface is in a multi-access segment. It is neither the DR nor the BDR for the segment; however, this command does not indicate whether 10.10.10.3 or 10.10.10.5 is the DR or BDR.
  3. The router R6 interface is in a multi-access segment. It is the BDR, which is why it is not adjacent to the other routers.
  4. The router R6 interface is in a multi-access segment. It is neither the DR nor the BDR for the segment. The DR for this segment would be the router with router ID 10.10.10.3. 
Correct answer: B
Question 5
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
Explanation:
Question 6
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
Question 7
Click the exhibit button. 
  
  
The OSPF adjacency between routers R3 and R1 is down. What is the problem?
  1. Area 1 of router R1 should not be configured as a stub.
  2. Router R3 has the incorrect authentication key type.
  3. Router R1 has the incorrect authentication key type.
  4. There is not enough information to tell.
Correct answer: C
Question 8
Click the exhibit button. 
  
Given the topology and the show commands, and assuming that router R2 advertises all of its loopbacks into OSPF, what is the correct router R1 configuration? 
  
  1. Option A 
  2. Option B
  3. Option C
  4. Option D
Correct answer: A
Question 9
In which of the following types of areas does an OSPF router not set the E bit in its Type 1 LSA?
  1. Not so stubby area
  2. Stub area
  3. Backbone area
  4. Normal area
Correct answer: B
Question 10
Click the exhibit button. 
  
In the topology shown, router R1 is an ASBR configured to export external routes to OSPF. 
Which of the following statements regarding the OSPF LSAs in the network is true?
  1. Router R1 generates a type 5 LSA that is flooded through all OSPF areas.
  2. Router R1 generates a type 7 LSA that is flooded through all OSPF areas.
  3. Router R1 generates a type 5 LSA that is flooded through area 1. Router R2 generates a type 7 LSA that is flooded through areas 0 and 2.
  4. Router R1 generates a type 7 LSA that is flooded through area 1. Router R3 generates a type 5 LSA that is flooded through areas 0 and 2.
Correct answer: D
