Question 5

Which two statements explain the operation of BFD asynchronous mode? (Choose two )

Options :

A :

BFD asynchronous mode with echo packets combines the control packets and echo packets into a single packet.

B :

BFD asynchronous mode without echo packets uses control packets, and BFD asynchronous mode with echo packets does not.

C : BFD asynchronous mode with and without echo packets use control packets.

D :

BFD asynchronous without echo packets has control packets sent back to the originating router, which echoes the control packet to detect failures.

E : BFD asynchronous mode with echo packets uses separate control packets and echo packets.
