Selected Answer: BCD
B. BGP (Border Gateway Protocol) BFD Support: BGP can utilize BFD to quickly detect path failures between BGP peers. Implementing BFD with BGP enhances the detection of failed paths, allowing for faster failover and improved network reliability. C. OSPF (Open Shortest Path First) BFD Support: OSPF integrates with BFD to expedite the detection of failed links. This rapid detection allows OSPF to recalculate routes promptly, maintaining efficient data forwarding. D. LACP (Link Aggregation Control Protocol) BFD Support: LACP can be configured to work with BFD. BFD monitors the health of individual member links in an aggregated bundle, enabling swift detection and isolation of failed links.

Selected Answer: BCD
Bidirectional Forwarding Detection (BFD) is a network protocol used for fast failure detection on paths between two routers or switches. It is commonly used with routing protocols to enhance their ability to detect failures quickly. The three protocols that support BFD are: B. BGP (Border Gateway Protocol) C. OSPF (Open Shortest Path First) D. LACP (Link Aggregation Control Protocol) RSTP (Rapid Spanning Tree Protocol) and FTP (File Transfer Protocol) do not support BFD.

i do understand this question is not only about routing protocols, but this years I knew that BFD is only for routing protocols such as BGP OSPF and RIP.... So why should I pick LACP as this is aggregation protocol ....
