Witch technology accomplishes this goal?

An engineer is working on an OSPF network design and wants to minimize the failure detection time and the impact on the router CPU.

Witch technology accomplishes this goal?

B . LSA delay interval
C . BFD
D . Fast hellos

Answer: C

Explanation:

BFD (Bidirectional Forwarding Detection) is a detection protocol designed to provide fast forwarding path failure detection times for all media types, encapsulations, topologies, and routing protocols. In addition to fast forwarding path failure detection, BFD provides a consistent failure detection method for network administrators. Because the network administrator can use BFD to detect forwarding path failures at a uniform rate, rather than the variable rates for different routing protocol hello mechanisms, network profiling and planning will be easier, and reconvergence time will be consistent and predictable.
