NO.31 Which of the following statements concerning OSPFv3 is false?

MD5 Authentication is not supported.

Router LSAs do not carry IPv6 prefix information

NSSA is not supported in OSPFv3.

OSPFv3 uses a 32-bit router ID.

NO.32 Which of the following statements regarding OSPF routing updates on a point-to-point link is true?

On a point-to-point link, there is no need for a DR and BDR election; all routing updates are sent to 224.0.0.5.

On a point-to-point link, a DR and BDR are elected. The DR sends link-state advertisements describing the network.

On a point-to-point link, a DR and BDR are elected. To ensure resiliency, both the DR and BDR send link-state advertisements describing the network.

On a point-to-point link, there is no need for a DR and BDR election. All routing updates are sent to the unicast address of the neighbor’s interface.

NO.33 Click the exhibit button.

Two neighboring OSPF routers have exchanged the packets shown. What state is the adjacency in?

Full; both routers are exchanging Helios to maintain the adjacency.

The adjacency is down.

The adjacency is in exstart state.

The adjacency is in the exchange state.

NO.34 Click the exhibit button.

Which of the following would correctly configure routers R2, R3, and R4?

Option A

Option B

Option C

Option D

NO.35 Click the exhibit button.

The OSPF adjacency between routers R3 and R1 is down. What is the problem?

Area 1 of router R1 should not be configured as a stub.

Router R3 has the incorrect authentication key type.

Router R1 has the incorrect authentication key type.

There is not enough information to tell.

NO.36 Graceful Restart is supported by what IGPs?

RIPv1 and RIPv2

OSPF

IS-IS

BGP

NO.37 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?

The prefix list reject should be “192.168.3.0/16 exact”.

Router R1 should be configured as an OSPF “asbr”.

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

The policy was likely not “committed” after creation.

This is not possible because OSPF cannot use import policies.

NO.38 Which of the following statements regarding area border routers in an OSPF network is true?

The term backbone router has the same definition as the term area border router.

An OSPF network needs at least one area border router to function.

Area border routers connect the backbone area to other areas in an OSPF network.

By definition, an area border router must perform route summarization between areas.

NO.39 What is the default priority value used for electing the DR on an Nokia 7750 SR running OSPF on an Ethernet?

Priority of 0

Priority of 1

Priority of 64

Priority of 255

NO.40 An OSPF router receives an update in which the sequence number, age, and checksum are the same as the entry already in the topological database. What action is taken by the router?

The link state information is not populated in the database but is forwarded to all neighbors

The link state information already in the database is overwritten and the age is reset

The link state information is not populated in the database and an acknowledgement is sent

The link state information is regarded as old and nothing is done.

NO.41 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?

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

Add the “summaries” option to the NSSA area configuration on router R1

Make a static route on router R1 to 192.168.3.1

Make a default route on router R2

NO.42 Click the exhibit button.

What can you deduce from the show command on router R6?

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.

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.

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.

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.

NO.43 What are the three databases maintained by a Link State Protocol?

Neighbor, adjacency, route table

Neighbor, topology, forwarding

Topology, routing, forwarding

There are only two databases: adjacency and topology

NO.44 Identify two attributes of Distance Vector Protocols: (Choose two)

Use split horizon by default.

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

Use holddown timers when topologies change to allow for convergence.

Maintain multiple databases: neighbor, topology and routing.

NO.45 Which of the following statements best describes the function of an OSPF Type 4 LSA?

A Type 4 LSA is originated by an ABR to describe a route to an ASBR to routers outside the area.

A Type 4 LSA is originated by an ASBR to describe a route to itself to routers outside the area.

A Type 4 LSA is originated by an ABR that is connected to a stub area. The LSA is injected into the backbone area to provide routing information.

A Type 4 LSA is originated by an ABR that is connected to a stub area. The LSA is injected into the stub area to provide routing information.
