Which three protocols support BFD? (Choose three.)
Which three protocols support BFD? (Choose three.)
BFD (Bidirectional Forwarding Detection) is typically used with routing protocols to ensure rapid detection of faults. Among the given options, BGP and OSPF are known to support BFD for expedited fault detection. RSTP (Rapid Spanning Tree Protocol), LACP (Link Aggregation Control 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 ....
Correct answer is ABC Ospf and BGB and RSTP

BCD are correct
