Multi-Factor Authentication (MFA) apps, especially time-based one-time password (TOTP) apps (e.g., Google Authenticator, Authy), rely on accurate time synchronization between the device and the authentication server. If the user recently traveled internationally, the device may have incorrect date/time settings due to time zone changes or failed synchronization, leading to MFA failure.
The most logical and non-intrusive first step is to verify and correct the date and time settings. This aligns with basic troubleshooting principles-start with the simplest and most likely cause before taking more drastic action.

To allow Remote Desktop Protocol (RDP) access, the firewall must be configured to allow inbound connections on TCP port 3389. If the Windows Firewall blocks RDP, users will not be able to connect remotely even if the feature is enabled in system settings.
B: Computer Management allows configuration of services and local users, but not network access.
C: User Accounts is for account setup and control, but enabling remote access requires firewall configuration.
D: Ease of Access is unrelated to remote connectivity-it's for accessibility features.

Outdated images and website data often result from cached files in the browser. The Internet Options panel in Windows (specifically under the General tab) allows users to clear browsing history, including cached images and files, which forces the browser to load the most current versions of web content.
A: Administrative Tools is used for advanced system management, not browser settings.
B: Windows Defender Firewall controls network traffic and security rules, not caching.
D: Ease of Access provides accessibility features for users with disabilities - unrelated to web browsing issues.

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.

In enterprise environments, network-based deployment solutions (such as Windows Deployment Services or SCCM) allow administrators to push images across the network to hundreds of devices efficiently. These tools support hardware-specific drivers (for different vendor classes) and can accommodate user-group configurations using task sequences or answer files.
A: and B (xcopy and robocopy) are file-level tools and not designed for full OS image deployment.
C: Using local tools per device is inefficient for large-scale rollouts (800 devices).
D: Network-based deployment is the industry standard for this scale.
