Difficulty: HardRemote Access Technologies and Tools

An IT technician needs to configure remote support capabilities for an enterprise environment. The requirements specify establishing secure, encrypted command-line management for remote headless Linux servers, as well as providing interactive desktop support to remote Windows 11 Enterprise users without terminating their active local desktop sessions. Which of the following protocol and tool choices MUST be implemented to fulfill these requirements? (Select TWO.)

  1. Open TCP port 22 on the network firewall to facilitate secure shell connections.Answer
  2. Utilize Microsoft Remote Assistance to perform interactive screen-sharing support sessions.Answer
  3. C
    Configure Telnet over TCP port 23 to securely administer the remote Linux operating systems.
  4. D
    Initiate Remote Desktop Protocol connections on TCP port 3389 to assist users without disrupting their console sessions.

Answer

The correct configurations are opening TCP port 22 for secure shell access and utilizing Microsoft Remote Assistance for interactive screen-sharing support.
Secure Shell (SSH) over TCP port 22 supplies encrypted terminal access ideal for managing Linux machines. Microsoft Remote Assistance (MSRA) enables interactive support sessions where the remote technician and the local user view and control the desktop environment concurrently.

Step-by-Step Solution

1
Identify the protocol required for secure command-line administration of headless Linux servers.
SSH (Secure Shell) encrypts traffic and operates over TCP port 22, fulfilling the server management requirement.
Telnet operates on TCP port 23 in cleartext and is inherently insecure, while RDP is primarily used for graphical interface management.
2
Determine the appropriate tool for interactive Windows desktop support that maintains the user's active session.
Microsoft Remote Assistance (MSRA) provides dual-control screen sharing where both the user and technician interact simultaneously.
Standard Remote Desktop Protocol (RDP) on client Windows editions locks or disconnects the local logged-in user upon connection.
