1. 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.

Link Local LSA

Router LSA

Network LSA

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.

11. What is the default inbound metric for RIP on theNokia7750 SR?

Whatever the advertised metric happens to be.

A value of 1.

This must be administratively set as there is no default value.

A value of 15.

12. 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?

Router R1 generates a type 5 LSA that is flooded through all OSPF areas.

Router R1 generates a type 7 LSA that is flooded through all OSPF areas.

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.

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.

13. What causes an adjacency to change from down to two ways?

When a link state update is received in response to a link state request.

When a router receives a Hello packet that contains its own router ID in the neighbor list from a neighbor.

When a router receives a database description packet from a neighbor.

When a link state acknowledgement is received in response to a link state update.

14. What is the default priority value used for electing the DR on anNokia7750 SR running OSPF on an Ethernet?

Priority of 0

Priority of 1

Priority of 64

Priority of 255

15. 10.10.5 is the DR or BDR.

C. 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.

D. 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.

16. What are the ways the RID can be created on anNokia7750 SR router? (Choose three)

From the last 32 bits of the chassis MAC address

From the first 32 bits of the chassis MAC address

The loopback IP address

By using the command "config router ospf rid

From the system IP address

From the highest interface IP address

17. Which of the following statements apply to link state protocol behavior? Choose three answers.

Routers broadcast the entire route table to all neighbors.

Information about directly connected links is sent to all neighbors.

An adjacency database is maintained by each router.

The sequence number for an update is incremented as it is flooded from router to router.

The topological database is the same for all routers in a single area.

18. 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.

Fast reroute capability

Control traffic prioritization

Route redistribution

Traffic engineering extensions

Cut through forwarding
