Difficulty: EasyRemote Access Technologies and Tools

Match each remote access technology or protocol with its primary operational characteristic and default port assignment.

  • SSH (Secure Shell)Encrypted command-line administration protocol operating over default TCP port 22
  • RDP (Remote Desktop Protocol)Graphical desktop access protocol operating over default TCP port 3389
  • TelnetUnencrypted legacy command-line protocol operating over default TCP port 23
  • MSRA (Microsoft Remote Assistance)User-initiated support tool allowing a technician to view and share control of an active desktop session

Answer

SSH matches encrypted command-line access on TCP port 22; RDP matches graphical desktop access on TCP port 3389; Telnet matches unencrypted legacy command-line access on TCP port 23; MSRA matches user-initiated active desktop session assistance.
SSH provides secure, encrypted command-line communication over TCP port 22. RDP delivers graphical desktop access over TCP port 3389. Telnet transmits unencrypted command-line data over TCP port 23. MSRA requires user initiation to enable interactive desktop troubleshooting.

Step-by-Step Solution

1
Differentiate command-line management protocols by security and default port assignment
SSH provides encrypted shell access on TCP port 22, whereas Telnet provides unencrypted cleartext shell access on TCP port 23.
CompTIA standards emphasize replacing cleartext protocols like Telnet with secure encrypted alternatives like SSH.
2
Distinguish graphical remote management tools by session interaction mode and port requirements
RDP connects directly to manage Windows desktops over TCP port 3389, while MSRA provides collaborative session sharing initiated by an end user invitation.
RDP is primarily used for administrative remote access, while MSRA is designed specifically for interactive desktop troubleshooting with user consent.
