Router R2 advertises the network 192.168.3.0/24 to router R1 via OSPF. A route policy has been constructed to discard the route on router R1; however, it is not working. What is the problem?

• A.Router R1 should be configured as an OSPF "asbr".
• B.This is not possible because OSPF cannot use import policies.
• C.The policy "reject" should be set for import rather than export.
• D.The policy was likely not "committed" after creation.
• E.The prefix list reject should be "192.168.3.0/16 exact".

Which of the following statements regarding OSPF routing updates on a multi-access network segment is true?

• A.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.
• B.In multi-access networks, a DR and BDR are elected only if the subnet masks on the router interfaces are less than /30
• C.In multi-access networks, a DR and BDR are elected. The DR sends link-state advertisements describing the network.
• D.In multi-access networks, a DR and BDR are elected only if there are more than two routers connected to the network segment.
