When configuring a filter, where should the most explicit entries be placed?

A. At the bottom

Click the exhibit button A. The route policy should be applied as in import policy

The 192 168 3.0/24 network is learned on router R1 via IS-IS Given the OSPF configuration shown, and assuming that the OSPF adjacency between routers R1 and R3 is up, why is the 192 168.3.0/24 route not in router R3's route table? (Choose two)

B. The no-redistribute-external command is used on router R1

C. The route policy is incorrect. It should say "from protocol ISIS" rather than "from protocol direct".

D. It is not possible to be an ASBR and an NSSA. The ASBR configuration should be removed.

E. The interface between routers R1 and R3 needs to be in OSPF area 0 rather than OSPF area 1 because a backbone area must always exist.

All ports in the network are operationally up and have a speed of 1Gbps.

Which of the following is TRUE?

A. Data traffic from network 192.168.1.0/24 to 192.168.3.0/24 will be forwarded through router R2.

B. Data traffic from network 192.168.3.0/24 to 192.168.1.0/24 will be forwarded through router R2.

C. The system interface of routers R1 and R3 must be included into OSPF for traffic to flow between the 192.168.1.0/24 and 192.168.3.0/24 networks.

D. The OSPF adjacency between router R1 and router R3 is operationally down.

Assume that OSPFv3 is properly configured on all routers and that router R4 advertises its system prefix into Area 0.

Which of the following best describes how router R5 learns router R4's IPv6 system prefix?

A. With a Router LSA originated by router R1.

B. With a Router LSA originated by router R5.

C. With a Router LSA originated by router R4.

D. With an Inter-Area Prefix LSA originated by router R1.

E. With an Inter-Area Prefix LSA originated by router R5.

F. With an Inter-Area Prefix LSA originated by router R4.

Which of the following best describes an OSPF Type 3 LSA?

A. A Type 3 LSA is generated by an ASBR only when route summarization is configured.

B. A Type 3 LSA is generated by an ABR only when route summarization is configured.

C. A Type 3 LSA is generated by an ASBR to describe routes to routers outside the area.

D. A Type 3 LSA is generated by an ABR to describe routes to routers outside the area.
