Which form of overlapping encryption domain is described as one gateways’ encryption domain
being fully contained within another gateways’ encryption domain?

A.
Full overlap

B.

C.

Explanation:

: This is the proper term for this situation, a VPN encryption domain is a group of networks or
hosts behind a firewalled gateway that participate in a VPN. Any traffic coming from one VPN
domain and going to another will be encrypting outbound, and then decrypted inbound at the other
end. We can have “Full overlap” and “Proper Subset” of overlapping in the VPN encryption
domains.
