Question # 11

What type of OSPF router generates a type 2 LSA?

Area Border Router

Autonomous System Boundary Router

Designated Router

All routers within an OSPF area.

Question # 12

Click on the exhibit.

The route table on router R2 shows the system address of router R5 but it does not show any of the interfaces from the non-OSPF area.

What may be causing this?

'asbr' is missing from router R1's configuration.

Router R1 needs to have an export policy added to it.

Router R5 does not have an export policy for these prefixes.

Router R1 needs to have an import policy added to it.

Question # 13

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.

Question # 14

Which of the following best describes the type of packets used by OSPF routers to exchange updates on a point-to-point link?

IP packets sent to an IP multicast address.

TCP packets sent to an IP multicast address.

IP packets sent to an IP unicast address.

UDP packets sent to an IP multicast address.

Question # 15

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.

Question # 16

When redistributing OSPF into RIP V2 what must be taken into consideration for the redistribution to take place?

The metric must be set accordingly for RIP

The subnet mask must be removed from the OSPF route

You must divide the cost of the OSPF route by three

The router must be configured as an ASBR

Question # 17

Graceful Restart is supported by what IGPs?

RIPv1 and RIPv2

OSPF

IS-IS

BGP

Question # 18

Which of the following statements regarding OSPF routing updates on a multi-access network segment is true?

In multi-access networks, a DR and BDR are elected only if there are more than two routers connected to the network segment.

In multi-access networks, a DR and BDR are elected only if the subnet masks on the router interfaces are less than /30.

In multi-access networks, a DR and BDR are elected. To ensure resiliency, both the DR and BDR send link-state advertisements describing the network.

In multi-access networks, a DR and BDR are elected. The DR sends link-state advertisements describing the network.

Question # 19

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
