Difficulty: HardRemote Access Technologies and Tools

Match each remote access technology or protocol on the left with its defining operational characteristic and port specification on the right.

  • Secure Shell (SSH)Provides an encrypted command-line session over TCP port 22 for secure remote system administration.
  • Remote Desktop Protocol (RDP)Provides full graphical desktop control over TCP port 3389 and locks the local user session on Windows client editions.
  • Microsoft Remote Assistance (MSRA)Allows a technician to interactively view and control a user's active session after the user generates an invitation.
  • TelnetTransmits unencrypted command-line communications in cleartext over TCP port 23.

Answer

Secure Shell (SSH) pairs with encrypted CLI over TCP port 22. Remote Desktop Protocol (RDP) pairs with full graphical control over TCP port 3389 that locks local sessions. Microsoft Remote Assistance (MSRA) pairs with invitation-based interactive session control. Telnet pairs with unencrypted cleartext CLI over TCP port 23.
Each technology is mapped according to standard network port assignments and session management behaviors. Secure Shell (SSH) encrypts terminal sessions on TCP port 22; Remote Desktop Protocol (RDP) provides exclusive GUI management on TCP port 3389; Microsoft Remote Assistance (MSRA) uses invitations for collaborative remote assistance; and Telnet sends unencrypted terminal data over TCP port 23.

Step-by-Step Solution

1
Analyze command-line remote access tools based on security and port numbers.
SSH provides encrypted administration using TCP port 22, whereas Telnet sends unencrypted cleartext data over TCP port 23.
Distinguishing secure protocols from insecure legacy protocols is critical for operational procedures.
2
Analyze Windows graphical remote access tools based on session handling and user interaction.
RDP uses TCP port 3389 and creates an exclusive session that locks the local monitor, whereas MSRA uses user-initiated invitations to allow dual-view interactive troubleshooting.
RDP is designed for remote workspace access, while MSRA is designed for real-time user support.
3
Map each protocol or tool to its exact operational definition.
All four items are matched to their corresponding characteristics.
Ensures complete alignment with CompTIA remote access specifications.
