A user contacts the help desk to request assistance with a program feature.

RDP stands for Remote Desktop Protocol and it is a protocol that allows a user to remotely access and control another computer over a network. A technician can use RDP to assist a user who is in a different building but on the same network by connecting to the user’s computer and viewing their screen, keyboard, and mouse. AAA, SSH, and VPN are not protocols that can be used to assist a user with a program feature.
