QUESTIN TEXT IS NOT AVAILABLE

which three statements about EIGRP and BFD are true ? (choose three.

A. BFD is independent of the routing protocol,so it can be used as a generic failure detection mechanism for EIGRP.

B. Some parts of BFD can be distributed to the data plane,so it can be less CPU-intensive than reduced timers, which exist wholly at the control plane.

C. Reduced EIGRP timers have an absolut minimum detection timer of 1-2 seconds; BFD can provide sub-second failure detection

D. BFD is tied to specific routing protocols and can be used for generic fault detection for the OSPF,EIGRP and BGP routing protocol

E. BFD is dependent on the EIGRP routing protocol,so it can be used as a specific failure detection mechanism

F. BFD resides on the control plane,so it is less CPU-intensive than if it resided on the date plane
