Answer: A
A call-back system in a net centric environment would mean
that a user with an id and password calls a remote server
through a dial-up line first, and then the server
disconnects and dials back to the user machine based on the
user id and password using a telephone number from its
database. Although the server can depend upon its own
database, it cannot know the authenticity of the dialer when
the user dials again. The server cannot depend upon the
sender's database to dial back as the same could be manipulated.
