An OSPFv3 router is attached to a non-OSPF domain that includes networks 2001:DB8:8::/64.2001 .DB8:9::/64 and 2001 :DB8:A::/64. Other routers in the OSPF domain see the prefix 2001, DB8:8::/64, but not the other two prefixes.

What could cause this?

A.

The router is not configured as an asbr.

B.

The router is not configured as an NSSA.

C.

The export policy is not applied to OSPFv3.

D.

The prefix list should be 2001:DB8:8::/46

Router R2 uses OSPF to advertise the network 192.168.3.0/24 to router R1. A route policy has been configured to reject the route on router R1.

Why doesn't the route policy work?

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 was not "committed" after creation.

D.

Router R1 cannot reject the route because OSPF does not support import policies

OSPF router R2 has both point-to-point and broadcast interfaces and it is not a DR for any interfaces. Router R2 detects the link failure between itself and router R1.

Which of the following is correct?

A.

Router R2 sends an update to 224.0.0.5 on its broadcast and point-to-point interfaces. The DR does not send any updates.

B.

Router R2 sends an update to 244.0.0.5 on its point-to-point interfaces. The DR sends an update to 224.0.0.6 on the broadcast network.

C.

Router R2 sends an update to 224.0.0.5 out its point-to-point interfaces and an update to 224.0.0.6 out its broadcast interface. The DR sends updates to 224.0.0.5 on the broadcast network.

D.

Router R2 sends an update to 224.0.0.6 out its point-to-point interfaces and an update to 224.0.0.5 out its broadcast interface. The DR sends an update to 224.0.0.6 on the broadcast networks.

Which OSPFv3 LSA type is generated by an ABR to advertise prefixes from one area to another?

Before the link failure, all routers have operational OSPF adjacencies between them and there is a BFD session between routers R1 and R3.

After the link failure, which of the following affects the IGP convergence time?

A.

The convergence time depends on the value of the OSPF hello timers on routers R1 andR3.

B.

The convergence time depends on the value of the OSPF hello timers and Dead interval on routers R1 and R3.

C.

The convergence time depends on the value of the BFD interval and multiplier settings on routers R1 andR3.

D.

The convergence time depends on the time taken by the switches to detect the link failure.

Which of the following about Type 4 LSAs is FALSE?

A.

A Type 4 LSA is not generated in a single area AS.

B.

A Type 4 LSA is generated by the ABRs of the area that contains the ASBR.

C.

A Type 4 LSA advertises the external networks connected to the ASBR.

D.

A Type 4 LSA is not flooded in the area that contains the ASBR.

An IS-IS router receives a CSNP that references an older LSP than the one in its database. What action is taken?

A.

The router sends a copy of the LSP from its database to its neighbor.

B.

The router sends a PSNP to its neighbor describing the LSP in its database.

C.

The router updates its database with the LSP and floods a copy to its other neighbors.

D.

The router sends a PSNP to its neighbor to request the LSP.

Which of the following is a feature of a black-hole static route?

A.

It discards packets based on the source address.

B.

It discards packets that match the destination prefix.

C.

It returns ICMP unreachable messages.

D.

It discards packets based on the egress port.

What is wrong with the following filter configuration from an Alcatel-Lucent 7750 SR?

RTR-B# configure filter

RTR-B>config>filter# ip-filter 1 create

RTR-B>config>filter>ip-filter$ entry 1 create

RTR-B>config>filter>ip-filter>entry$ match src-ip 172.2.0.0/16

RTR-B>config>filter>ip-filter>entry# action drop

RTR-B# configure router interface toRTR-A

RTR-B>config>router>if# egress

RTR-B>config>router>if>egress# filter ip 1

A.

There is nothing wrong with this filter

B.

The filter should be applied to the ingress and not the egress.

C.

The mask cannot be a "/" value, it must be in dotted decimal.

D.

All traffic is being blocked
