Given answer is correct per cisco book page 971.
BFD to the rescue. BFD is a “detection” protocol that works with all media types, routing
protocols, topologies, and encapsulations.
The correct answer is:
C. It provides uniform failure detection regardless of media type.
BFD (Bidirectional Forwarding Detection) is a protocol used for rapid failure detection in computer networks. One of its primary functions is to provide uniform and consistent failure detection regardless of the media type or technology being used in the network. BFD can be used with various network media types, including Ethernet, SONET/SDH, MPLS, and more. It ensures that failure detection is fast and consistent, making it a valuable tool for network reliability and fast convergence. Therefore, option C is the correct description of the function of BFD.
