A systems technician is standardizing operational documentation for remote administration tools and support workflows across an enterprise network environment. Match each remote access tool or protocol to its primary operational characteristic and protocol constraint.
- Microsoft Remote Assistance (MSRA)Establishes a temporary, interactive screen-sharing session over TCP port 3389 that requires explicit user initiation or invitation.
- Remote Desktop Protocol (RDP)Provides full graphical desktop control over TCP port 3389, but incoming host server capability is restricted to Windows Pro, Enterprise, and Server editions.
- Secure Shell (SSH)Delivers secure, encrypted command-line terminal access to manage remote systems and network infrastructure over TCP port 22.
- Virtual Network Computing (VNC)Uses the Remote Frame Buffer (RFB) protocol over TCP port 5900 to transmit screen pixel displays independently of the underlying operating system.
Answer
Microsoft Remote Assistance (MSRA) matches with establishing a temporary, interactive screen-sharing session over TCP port 3389 requiring user invitation. Remote Desktop Protocol (RDP) matches with providing full graphical desktop control over TCP port 3389 restricted to Windows Pro, Enterprise, and Server host editions. Secure Shell (SSH) matches with encrypted command-line terminal management over TCP port 22. Virtual Network Computing (VNC) matches with cross-platform desktop sharing using RFB over TCP port 5900.
Each tool is correctly matched based on its protocol, default port number, and operational capabilities: MSRA (TCP 3389, interactive invitation), RDP (TCP 3389, full administrative control on Windows Pro/Enterprise), SSH (TCP 22, secure CLI management), and VNC (TCP 5900, cross-platform RFB graphical desktop access).
