4A0-101 practice questions, page 4 of 13, with answer review and explanations.

Question 16

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

Question 17

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.

Question 18

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.

Question 19

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

Question 20

Click the exhibit button. The following command sequence is executed on router R2: ✑ A: R2# configure router ospf router-id 10.10.10.99 ✑ A: R2# configure router router-id 10.10.10.66 On router R1, what router ID appears for router R2 directly after these commands are executed?

  1. 10.10.10.99
  2. 10.10.10.66
  3. 10.10.10.2
  4. 10.10.10.1
