Which of the following is a proprietary protocol developed by microsoft that provides a user with a graphical interface to another computer?
(a) secure sockets layer (ssl)
(b) layer 2 tunneling protocol (l2tp)
(c) point-to-point tunneling protocol (pptp)
(d) remote desktop protocol (rdp)

(D) Remote Desktop Protocol (RDP)

Explanation:

Remote Desktop Protocol (RDP) is a networking protocol developed by Microsoft that provides a graphical user interface to another computer. This enables the remote user to interact with the machine as if they were working on it locally. The Secure Socket Layer (SSL) on the other hand, is a cryptographic protocol used in internet security. Then Layer 2 Tunneling Protocol (L2TP) and Point-to-Point Tunneling Protocol (PPTP) are computer networking protocol used when configuring and setting up Virtual Private Networks (VPNs) which allows a user to access a private network through a public network.
