The P4S company is deploying OSPF on a point-to-multipoint Frame Relay network. The remote sites needn??t to communicate with each other and there are a relatively small number of sites (scaling is not a concern). How to configure OSPF for this topology in order to minimize the additional routing information injected into the network and keep the configuration size and complexity to a minimum?
A. Configure the link as OSPF nonbroadcast and manually configure each of the remote sites as a neighbor.
B. Configure the link as OSPF broadcast and configure the hub router to always be the designated router.

A company plans to include Nonstop Forwarding and Bidirectional Forwarding Detection as a part of their network redundancy plan. In which two ways do NSF and BFD work together when different hardware platforms are compared? (Choose two.)
A. During supervisor engine or routing engine failover, the NSF feature will always ensure that the BFD at the peer router will not trigger a link down independent of the used hardware platform.
B. At some hardware platforms, BFD and NSF are not supported together. During supervisor engine or routing engine failover, the BFD at the peer router will trigger a link down.
C. To ensure that BFD at the peer router will not trigger a link down during NSF, the BFD packets must be processed fast enough, and, during supervisor engine or routing engine failover, by processing the BFD independent from the supervisor engine or routing engine.
D. Because BFD is always processed at the line cards (not at the supervisor engine or routing engine), a supervisor engine or routing engine failover will not affect the BFD peer router.
E. Because BFD is always processed at the supervisor engine or routing engine, a supervisor engine or routing engine failover will alwaystrigger a link down at the peer router.
