If the phone works on Wi-Fi but not off Wi-Fi, the most likely issue is that cellular data is disabled (or restricted). This aligns directly with the CompTIA A+ objective language for mobile troubleshooting, which explicitly includes “wireless/cellular data network (enable/disable).” After travel, users often enable airplane mode or disable cellular data to avoid roaming charges, and sometimes forget to re-enable it.

Quentin Docter’s mobile connectivity discussion repeatedly distinguishes Wi-Fi access from cellular connectivity and treats cellular settings as a primary area to verify when Internet access is not available away from Wi-Fi. While data caps/limits could throttle service, they usually don’t make all non-Wi-Fi browsing and email impossible immediately. VPN issues might block some access, but the simplest “most likely” resolution based on the symptom is re-enabling cellular data. Reinstalling the SIM is possible, but again not the first, most likely fix given the scenario framing. Therefore, Enable cellular data (A) is correct.

The correct answer is B. VNC . The key phrase is graphical interface access . VNC, or Virtual Network Computing, is a remote-control technology used to share and control graphical desktops. Quentin Docter’s Complete Study Guide explains that VNC is a remote control tool for desktop sharing, uses a client-server model, and allows remote control of the host where the VNC server is installed. The Mike Meyers/Mark Soper material also explains that SSH is excellent for command-line administrative tasks, but when full graphical desktop access is needed, a remote desktop application is required; VNC is identified as cross-platform and usable for remote graphical control. SSH provides secure command-line access, not a full graphical interface by default. WinRM is mainly a Windows remote-management technology. Telnet is an insecure text-based remote access protocol and should not be used for secure remote administration.

Group Policyis the standard administrative tool for setting user permissions across domain-joined systems.

FromQUENTIN DOCTER – COMPLETE Study Guide:

“Use Group Policy to enforce user rights, including disabling guest account access on domain computers.”

If unauthorized or non-standard applications are appearing on systems and users are receiving licensing prompts, it’s likely users are installing software themselves. Removing users from the local administrators group will prevent them from installing software without approval and reduce the likelihood of introducing unapproved or malicious programs.

A. Deploying a PKI helps with secure communications but doesn’t address user software installation rights.

C. Blocking suspicious websites is helpful but doesn’t prevent local installations.

D. Stricter UAC may add prompts but can still be bypassed by admin users.
