A.An OSPF type 3 LSA is an inter-area LSA, generated by the ABR to describe a route to neighbors outside the area.

B.An OSPF type 3 LSA is an intra-area LSA, generated by the ABR only when route summarization is configured.

C.An OSPF type 3 LSA is an inter-area LSA, generated by the ABR only when route summarization is configured.

D.An OSPF type 3 LSA is an inter-area LSA, generated by an ASBR to describe external routes.

A.A Type 4 LSA is originated by an ABR to describe a route to an ASBR to routers outside the area.

B.A Type 4 LSA is originated by an ASBR to describe a route to itself to routers outside the area.

C.A Type 4 LSA is originated by an ABR that is connected to a stub area. The LSA is injected into the backbone area to provide routing information.

D.A Type 4 LSA is originated by an ABR that is connected to a stub area. The LSA is injected into the stub area to provide routing information.

A.Type 7

B.Type 3

C.Type 4

D.Type 1

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

B.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.

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

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

A.Route redistribution

B.Cut through forwarding

C.Control traffic prioritization

D.Fast reroute capability

E.Traffic engineering extensions
