Answer 1

Telnet, TFTP (Trivial File Transfer Protocol), SNMP (Simple Network Management Protocol), and SMTP (Simple Mail Transfer Protocol) all function at the Process/Application layer of the DoD (Department of Defense) model, which is often referred to as the application layer. This layer corresponds to the top layer of the DoD model, and it encompasses protocols that provide communication services directly to user applications.

So, the correct choice is:
