Which process is used to protect transmitted data in a vpn? select one:
a. tunneling
b. ppp
c. voip
d. packet-switching
e. chaining?

For the answer to the question above, I believe the answer is
a. tunneling

this involves establishing and maintaining a logical network connection (that may contain intermediate hops).
packets constructed in a specific VPN protocol format are encapsulated within some other bases or carrier protocol, then transmitted between VPN client and server, and finally de-encapsulated on the receiving side.
