Difficulty: HardRemote Access Technologies and Tools

A system administrator is attempting to provide interactive remote assistance to a user whose workstation is located at a branch office connected via an IPsec VPN tunnel. The workstation runs Windows 11 Home edition. The administrator attempts to initiate a Remote Desktop session using mstsc.exe over TCP port 3389, but the connection is rejected immediately. Verification confirms that network routing across the VPN is fully operational and boundary firewalls permit the traffic. Which of the following best accounts for this connection failure, and which native tool should be used instead?

  1. Windows 11 Home edition does not support incoming Remote Desktop host sessions; the administrator should use Quick Assist or Microsoft Remote Assistance (MSRA).Answer
  2. B
    The local Windows Defender Firewall drops RDP traffic over VPN connections by default; the administrator must tunnel the connection through SSH on TCP port 22.
  3. C
    Remote Desktop hosting requires the workstation to be joined to an Active Directory domain; the administrator must use Telnet on TCP port 23 to perform a remote domain join first.
  4. D
    The Remote Desktop Services service is disabled by default in Windows Control Panel; the administrator must use Computer Management MMC to launch the VNC service remotely.

Answer

Windows 11 Home edition does not support acting as a Remote Desktop host (RDP server). To provide remote technical support, the administrator should use native tools like Quick Assist or Microsoft Remote Assistance (MSRA), which are fully supported on Home editions.
The correct option identifies that Windows 11 Home edition lacks incoming Remote Desktop host capabilities. While users on Windows Home can use the Remote Desktop client to connect to other systems, Windows Pro, Enterprise, or Education is required to accept incoming RDP connections over TCP port 3389. For interactive support on Home editions, native tools such as Quick Assist or Microsoft Remote Assistance (MSRA) must be utilized.

Step-by-Step Solution

1
Analyze OS edition capabilities and protocol features
Identified that Windows 11 Home includes the RDP client (mstsc.exe) but lacks the RDP host server functionality.
CompTIA A+ guidelines specify that RDP hosting requires Windows Pro, Enterprise, or Education editions.
2
Evaluate network diagnostics provided in the scenario
Ruled out network layer routing, IPsec VPN tunnel issues, and boundary firewall port blocking (TCP 3389).
The failure occurs at the endpoint application/OS level due to edition limitations rather than network connectivity blocking.
3
Select the appropriate native Windows remote support technology
Selected Quick Assist / Microsoft Remote Assistance (MSRA).
MSRA and Quick Assist allow interactive remote support sessions on all client editions of Windows, including Home.
