Selected Answer: B
BFD is enabled by default on all vEdge routers and we cannot disable it. For SDWAN, BFD is used to detect path liveliness (up/down) and measure quality (loss/latency/jitter/IPSec tunnel MTU). https://www.certprepare.com/bi-directional-forwarding-detection-bfd-tutorial#:~:text=For%20SDWAN%2C%20BFD%20is%20used,jitter%2FIPSec%20tunnel%20MTU).
