A remote user is experiencing issues with Outlook settings and asks a technician to review the settings. Which of the following can the technician use to access the user's computer remotely?

A VPN (Virtual Private Network) provides secure network connectivity to a private network but does not inherently offer remote desktop control.

Remote Desktop Protocol (RDP) allows a technician to establish a graphical remote desktop session to a user's Windows computer, providing full control of the desktop environment to review and modify Outlook settings as if they were physically present.

RMM (Remote Monitoring and Management) is a suite of tools for managing multiple endpoints and can include remote access, but RDP is the specific protocol used for graphical remote desktop control in many RMM solutions for Windows.

SSH (Secure Shell) provides a secure command-line interface for remote access, which is suitable for server management but not for graphically interacting with a user's desktop application like Outlook.
