Linux is an open-source operating system that is freely available and does not require traditional licensing fees. It is highly versatile and scalable, making it suitable for both workstations and servers. Many enterprise environments use Linux to reduce software costs and benefit from robust server features.

B. Windows requires per-device or per-user licensing for both workstation and server editions.

C. macOS is proprietary and limited to Apple hardware with licensing restrictions.

D. Chrome OS is designed for lightweight devices and lacks server functionality.

NET Framework versions are often required for applications to run. If an older app requires .NET Framework 3.5, it must be explicitly installed as it is not included by default in newer versions of Windows. The best method to do this safely is through the built-in "Turn Windows features on or off" utility, which downloads and installs it via official Microsoft services.

B. Using third-party repositories is unsafe and not recommended.

C. Installing .NET 4 does not include 3.5; versions are not fully backward compatible.

D. The issue is technical, not a security incident for the SOC team.

When a spreadsheet becomes very large, opening and processing it requires more memory (RAM). If the system doesn't have sufficient memory, it may fail to load the file properly. Upgrading or increasing the available RAM can resolve performance and loading issues with very large files.

A. Restore points roll back system settings, not individual file content.

C. Defragmentation optimizes disk performance but won’t help with memory issues.

D. Network speed has no effect if the file is stored and opened locally.

Badge readers are electronic access control systems that require authorized users to scan a badge (e.g., RFID or magnetic strip cards) to gain access to restricted physical locations. These systems typically log all access attempts—successful or denied—providing both detection and recording of access events.

A. Bollards are physical barriers to prevent vehicle access.

B. Video surveillance can record access visually but does not track identity unless integrated with access control systems.

D. A fence restricts access but doesn't detect or record who entered.

An Acceptable Use Policy (AUP) outlines the rules and guidelines for employees or users regarding the appropriate use of company systems, resources, and internet access. It defines permitted and prohibited activities, helping to mitigate security risks and establish clear behavioral expectations.

B. MNDA (Mutual Non-Disclosure Agreement) deals with confidentiality, not usage guidelines.

C. DRM (Digital Rights Management) controls access to copyrighted content.

D. EULA (End User License Agreement) pertains to software licensing, not internal policies.

The correct answer is B. Restarting the print spooler from services, because the problem is isolated to one user and the print job is stuck or failed in the local print queue. This strongly indicates a print spooler service issue on the user’s workstation.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, the print spooler manages print jobs sent from applications to printers. If the spooler service hangs or becomes unstable, print jobs may fail even though network connectivity and the printer itself are functioning correctly.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that restarting the print spooler is a standard troubleshooting step when jobs remain in a failed or paused state. This clears the queue and reloads the service without requiring a full system reboot.

The Mike Meyers / Mark Soper Lab Manual reinforces that reinstalling printers should be done only after service-level troubleshooting has failed. Printing from another computer is unnecessary because other users are already printing successfully, confirming the printer and network are operational.

Because the failure is local to the user and visible in the queue, restarting the print spooler service is the most logical and efficient next step, making B the correct answer.
