The net use command in Windows is used to map (assign) a shared drive from the command line. The syntax typically looks like: net use X: \server\share where X is the drive letter and \server\share is the network path.
A). pathping tests network latency and packet loss.
B). nslookup is used for DNS troubleshooting.
D). tracert shows the route packets take to reach a destination - not for drive mapping.

To work remotely without physically transporting a workstation, the user needs:
* C. RDP (Remote Desktop Protocol): Allows graphical remote access to a Windows PC at the office.
* D. VPN (Virtual Private Network): Establishes a secure tunnel to access the corporate network remotely, making the internal PC reachable.
A: SPICE is used in virtual machine environments and is not typically used for end-user remote desktop access.
B: SSH is a text-based remote access tool used mostly for Linux systems.
E: RMM (Remote Monitoring and Management) is used by IT administrators for support - not end-user remote access.
F: WinRM is used for Windows remote management via PowerShell, not for full desktop access.

The correct answer is C. SSH (Secure Shell), because SSH is the standard method for secure, command-line- based remote management of network devices, including switches, routers, and firewalls. Network switches typically do not provide graphical interfaces, and administrators interact with them using a command- line interface (CLI).
According to the Quentin Docter - CompTIA A+ Complete Study Guide, SSH is widely used to securely access and manage network infrastructure devices. It encrypts all communication between the technician's system and the remote device, protecting credentials and command output from interception.
The Travis Everett & Andrew Hutz - CompTIA A+ All-in-One Exam Guide explains that SSH allows administrators to execute commands remotely and capture text-based output, which can easily be copied and shared for documentation or escalation. This makes it ideal for fulfilling requests that involve running commands and returning results.
The Mike Meyers / Mark Soper Lab Manual clarifies that RDP and VNC are graphical desktop-sharing tools typically used for managing workstations or servers, not network switches. WinRM is used for Windows system management, not network hardware.
Because the task involves secure CLI access to a network switch, SSH is the correct and expected tool, making C the correct answer.

The su (substitute user) command is used in Linux to switch to another user account, most commonly to escalate privileges by switching to the root (administrator) account. It allows administrative tasks to be performed in a terminal session.
A: runas is a Windows command for executing a program under another user's context.
B: cmcl is not a valid Linux or administrative command.
C: net user is a Windows command for managing local user accounts.
