What are two benefits of using BFD for failure detection in the design of a network? (Choose two.)

BFD is specifically engineered for rapid failure detection, capable of identifying link or path failures in milliseconds - well under one second - far faster than native routing protocol hello and dead timer mechanisms.

BFD operates as a protocol-agnostic failure detection mechanism that integrates with multiple routing protocols including EIGRP, IS-IS, OSPF, and BGP, providing a single, standardized detection framework across heterogeneous protocol environments and reducing per-protocol tuning complexity.

BFD does not eliminate routing protocol hello mechanisms; it supplements them by providing faster detection while protocol hellos continue to maintain neighbor relationships independently.

BFD cannot be used on all interface types; it has known limitations on certain multi-access, asynchronous, and tunnel interfaces where it may be unsupported or unreliable.

BFD is not fully independent of the network protocol in practice; it must be explicitly configured alongside specific routing protocols, which then act on BFD failure notifications to trigger reconvergence.
