Zorluk: Çok zorRemote Access Technologies and Tools

Match each remote access technology or protocol on the left with its corresponding technical characteristic, default port configuration, and operational requirement on the right.

  • Remote Desktop Protocol (RDP)Uses TCP port 3389 to create an independent graphical host session; requires Windows Pro, Enterprise, or Education edition to host incoming connections.
  • Microsoft Remote Assistance (MSRA)Uses TCP port 3389 to allow a user to invite a helper into their active desktop session; supported on Windows Home and Pro editions.
  • Secure Shell (SSH)Operates over TCP port 22 to provide an encrypted command-line interface for secure remote administration of operating systems and network devices.
  • TelnetOperates over TCP port 23 to provide an unencrypted command-line interface that transmits authentication credentials in cleartext.
  • Virtual Network Computing (VNC)Uses the Remote Frame Buffer (RFB) protocol over default TCP port 5900 to offer platform-independent graphical desktop sharing.

Cevap

RDP matches TCP 3389 with host support limited to Windows Pro/Enterprise; MSRA matches TCP 3389 session sharing supported on Home and Pro editions; SSH matches encrypted CLI administration on TCP 22; Telnet matches unencrypted cleartext CLI management on TCP 23; VNC matches cross-platform RFB graphical control on TCP 5900.
Matching each technology correctly requires distinguishing between Windows OS edition constraints (RDP host vs MSRA), default port numbers (TCP 22, 23, 3389, 5900), and protocol security characteristics (SSH encrypted vs Telnet cleartext; RDP/MSRA native vs VNC RFB cross-platform).

Adım Adım Çözüm

1
Analyze Windows graphical remote access protocols and edition constraints.
Differentiate RDP (discrete session, host requires Windows Pro/Enterprise/Education, TCP 3389) from MSRA (shared active session, invitation-based, works on Home editions, TCP 3389).
CompTIA exams strictly evaluate the host capability limitation of Windows Home edition regarding incoming RDP versus user-assisted MSRA.
2
Evaluate command-line interface (CLI) remote access protocols and security postures.
Identify SSH as the secure, encrypted terminal access protocol on TCP port 22, and Telnet as the legacy, unencrypted cleartext terminal protocol on TCP port 23.
Security best practices demand replacing unencrypted protocols like Telnet with encrypted alternatives like SSH.
3
Identify cross-platform graphical remote control standards.
Associate VNC with the Remote Frame Buffer (RFB) protocol and default listening port TCP 5900.
VNC is the standard open-source cross-platform tool for graphical desktop access across mixed operating system environments.
