How is the cost of a virtual link in OSPF calculated?()
A. Takes the metric of the outgoing interface.B. Uses the metric that is assigned during configuration.C. Uses the path metric to reach the virtual link neighbor.D. Uses a default of zero unless otherwise specified.
考题
Refer to the exhibit. Will redistribute d RIP routes from OSPF Area 2 be allowed in Area 1? ()
A. RIP routes will be allowed in Area 1 only if they are first redistributed into EIGRP.B. Because NSSA will discard type 7 LSAs, redistributed RIP routes will not be allowed in Area 1.C. Redistrib uted RIP routes will be allowed in Area 1 because they will be changed into type 5 LSAs in Area 0 and passed on into Area 1.D. Redistributed RIP routes will be allowed in Area 1 because they will be changed into type 7 LSAs in Area 0 and passed on into Area 1.E. Because Area 1 is an NSSA, redistributed RIP routes will not be allowed.
考题

On the same router, enter the Summary - address 10.10.1.0 255.255.255.128 subcommand.D. On the same router, enter the Area 1 range 10.10.1.0 255.255.255.128 subcommand.E. On the same ro uter, enter the Area 2 range 10.10.1.0 255.255.255.128 subcommand.

A. Router R1 will only establish full adjacency with the DR and BDR on broadcast multi- access networks.B. Router R2 has been elected as a DR for the broadcast multiaccess network in OSPF area 1.C. Routers R1 and R2 are configured as stub routers for OSPF area 1 and OSPF area 2.D. Router R1 and R2 are configured for a virtual link between OSPF area 1 and OSPF area 2.E. The Hello parameters on routers R1 and R2 do not m atch.
