When an OSPF design is planned, which implementation can help a router not have memory resource issues?()
A. Have a backbone area (area 0) with 40 routers and use default routes to reach external destinationsB. Have a backbo ne area (area 0) with 4 routers and 30,000 external routes injected into OSPFC. Have less OSPF areas to reduce the need for interarea route summarizationsD. Have multiple OSPF processes on each OSPF router. Example, router ospf 1, router ospf 2

Which description regarding OSPF Network LSAs is correct?()
A. They are originated by Area Border Router and are sent into a single area to advertise an Autonomous System Border Router.B. They are originat ed by Area Border Routers and are sent into a single area to advertise destinations outside that area.C. They are originated by the DR on every multi - access network. They include all attached routers including the DR itself.D. They are originated by every router in the OPSF network. They include all routers on the link, interfaces, the cost of the link, and any known neighbor on the link.

Refer to the exhibit. OSPF is configured on all routers in the network. On the basis of the show ip ospf n eighbor output, what prevents R1 from establishing a full adjacency with R2? ()
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.
