When an OS reaches its end of life (EOL), it no longer receives updates or support, including critical security patches.

From the Quentin Docter Study Guide:

“End-of-life means the manufacturer no longer supports the OS with updates or security patches, which exposes systems to vulnerabilities unless upgraded”.

All-in-One Exam Guide adds:

“End-of-life notifications serve as a final warning that continued use of the OS will be insecure and unsupported. It’s crucial for administrators to plan migration”.

This ensures the workstation communicates properly within that segment.

A. DNS server restriction is unrelated to manual IP configuration.

B. Allow lists refer to traffic access, but manual IP assignment is due to lack of DHCP, not allow lists.

D. NAC servers control access but don't replace the need for IP addressing.

The attacker’s goal is to hold the data hostage until the victim pays to restore access.

A. Keylogger records keystrokes and doesn’t encrypt files.

C. Phishing is a social engineering tactic to gather credentials, not to encrypt data.

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.

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.

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.

Comprehensive and Detailed Explanation From Exact Extract:

To ensure the authenticity of a downloaded application, the most reliable method is to verify the file’s hash (e.g., SHA256, MD5) against the value provided by the legitimate vendor. If the hash values match, the file has not been altered or tampered with. This verification confirms the integrity and authenticity of the executable.

B. Process IDs are dynamic and not unique to specific software.

C. Running in safe mode doesn’t validate legitimacy—it only runs the app in a minimal environment.

D. File names can be spoofed; matching the name does not prove authenticity.
