Remote Desktop Protocol (RDP)

Correct Answer: Allow remote connections

In order to establish a Remote Desktop Protocol (RDP) session, the remote computer must first be configured to allow remote connections. This is the main requirement for establishing RDP connections. Without this, the technician would not be able to connect to the remote user's computer. The other options, while they can enhance an RDP session, are not requirements. Enabling printer redirection merely allows printing at the remote machine. Enabling remote audio allows audio from the remote machine to be heard at the client machine. Enabling Network Level Authentication is a security feature that helps protect against hacking attempts by requiring the connecting user to be authenticated before a session is established.

Correct Answer: Enable Network Level Authentication

The best way to improve RDP (Remote Desktop Protocol) security is to 'Enable Network Level Authentication'. Network Level Authentication or NLA is a security measure that adds an extra layer of authentication before an RDP session is established, reducing system exposure to potential threats. On the contrary, the other answers do not enhance security. 'Decreasing the color depth' might improve performance by reducing the quantity of data sent during a session, but it doesn't enhance security. 'Enabling remote audio' is a feature that redirects audio from a remote computer to the local client or controls the audio on a remote computer, but it doesn’t improve security either. Lastly, 'Switching to full-screen mode' only changes the viewing mode of the RDP session but doesn't have any impact on the security of the connection.

Correct Answer: Enable plug and play devices

To allow USB devices to work within an RDP (Remote Desktop Protocol) session, you should 'Enable plug and play devices'. This option allows the USB devices connected to the local computer to be available during the RDP session, thus ensuring the application functions correctly. The other options are not suitable because 'Clipboard redirection' only allows clipboard functions like copy-paste to work between the local and remote systems, but it doesn't facilitate USB device connectivity. 'Remote audio' enables audio to be heard from the remote system, it has nothing to do with USB device connectivity. 'Network Level Authentication' is a security measure for protecting the system before a full connection is established, it does not facilitate USB device activity within an RDP session.
