Which term represents the encryption concept commonly associated with securing SD-WAN traffic between edge devices?

Explanation:
End-to-end encryption means securing data from the originating edge device all the way to the destination edge, so the payload stays encrypted across the entire SD-WAN path. This is exactly what’s needed when traffic travels through multiple hops and overlay tunnels between edge devices, ensuring that only the communicating endpoints can decrypt and access the content. In SD-WAN, the overlay tunnels between edges are encrypted (often using IPsec or TLS) to protect data in transit across the network, which aligns with the idea of end-to-end encryption. The other terms listed aren’t encryption concepts used in this context and don’t describe securing SD-WAN traffic between edges.
