Options:

A.

Use split horizon by default.

B.

Send information about directly connected links to neighbors at periodic intervals.

C.

Use holddown timers when topologies change to allow for convergence.

D.

Maintain multiple databases: neighbor, topology and routing.

Question 10

Click the exhibit button.

192.168.3.1 is a loopback interface on router R2 and is distributed to OSPF area 0, but the ping fails from router R3. Which of the following is a possible solution to the problem?

Options:

A.

Add the "originate-default-route" option in the NSSA area configuration on router R3

B.

Add the "summaries" option to the NSSA area configuration on router R1

C.

Make a static route on router R1 to 192.168.3.1

D.

Make a default route on router R2

Question 11

Which of the following cannot be used as a matching criterion in route policy statements?

Options:

A.

Source IP address

B.

TCP source port

C.

Prefix list

D.

Protocol type

Question 12

What are the three databases maintained by a Link State Protocol?

Options:

A.

Neighbor, adjacency, route table

B.

Neighbor, topology, forwarding

C.

Topology, routing, forwarding

D.

There are only two databases: adjacency and topology

Question 13

Click the exhibit button.

Router R2 advertises the network 192.168.3.0/24 to router R1 via OSPF. A route policy has been constructed to discard the route on router R1; however, it is not working. What is the problem?

Options:

A.

The prefix list reject should be "192.168.3.0/16 exact".

B.

Router R1 should be configured as an OSPF "asbr".

C.

The policy "reject" should be set for import rather than export.

D.

The policy was likely not "committed" after creation.

E.

This is not possible because OSPF cannot use import policies.

Question 14

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.
