Many modern commercial software applications (including photo editors like Adobe Photoshop) offer tiered features based on user subscriptions or license levels. If certain features are locked and prompt for a login, the issue is likely due to a missing or unassigned software license. Assigning the correct license through a centralized license management system (such as Adobe Admin Console or Microsoft 365 portal) will enable those features.
B). VPN connection does not affect local software licensing.
C). Repairing the application does not resolve license entitlement.
D). Reinstalling the software won't help unless the license is assigned.

Screensaver lockshelp protect unattended workstations.

"Applying a BIOS password adds a pre-boot security layer. Screensaver locks help protect logged-in sessions during idle times."

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.

If internal resources (such as intranet or internal apps) can ' t be accessed but external sites work, this often points to aDNS issue, where the system isn ' t resolving internal domain names correctly.
FromAll-in-One Exam Guide:
"When internet access is functional but internal sites fail to load, the issue usually lies with DNS resolution.
Internal resources often require internal DNS servers, which may not be configured correctly."

A "central log-in" means users can authenticate using a centralized account database rather than separate local accounts on each PC-this is a core feature of a Windows domain . Mike Meyers explains that a Windows domain makes it easy for anyone with a domain account to log on to any computer in the domain with a single account , a process called "single sign-on (SSO)," and that users do not need a separate local account stored on every computer. The All-in-One guide reinforces the same: in a domain, the domain controller stores domain accounts and "a user logging on to any computer on the domain may use their one domain account to log on to the entire network." Active Directory is the directory service commonly used to implement domains, but the question asks what is required for centralized logon on the workstation side- the computer must be joined to the domain (domain membership). Workgroups use only local accounts, and Local Group Policy Editor manages policies locally, not centralized authentication.
