The CompTIA A+ Core 2 2025 Exam (220-1202)

A corruptedMaster Boot Record (MBR)is a common issue after disk manipulation. Booting from installation media and using tools like bootrec to repair the MBR can resolve the problem.

Travis Everett – All-in-One Exam Guideexplains:

“A damaged MBR may result in the OS not loading. Booting from recovery or installation media and selecting startup repair or running bootrec commands can restore functionality.”

The amount of installed RAM is the key factor in determining whether a 64-bit OS is needed. A 32-bit operating system cannot effectively address more than 4GB of RAM. Since this system has 16GB of RAM, a 64-bit OS is required to utilize the full memory.

B. An Intel i7 CPU supports both 32-bit and 64-bit OS installations, so it alone doesn’t determine the need.

C. HDD size does not influence OS architecture selection.

D. Ethernet speed is a network consideration and not related to OS architecture.

Carbon fiber filamentcan producefine particles or fumesduring printing, which may be harmful when inhaled. Wearing anair filter maskis essential to protect the respiratory system.

FromQuentin Docter – CompTIA A+ Complete Study Guide:

“When working with advanced materials like carbon fiber, always use appropriate personal protective equipment such as air filter masks to prevent inhalation of dangerous particles.”

The correct answer is C. BAT, because batch files are specifically designed to execute a sequence of commands automatically in Windows environments. They are commonly used for startup tasks such as launching applications, mapping network drives, setting environment variables, or running maintenance scripts.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, batch files (.bat) are text-based scripts interpreted by the Windows Command Processor (cmd.exe). They are lightweight, easy to create, and can be placed directly in startup folders or scheduled through system tasks.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide emphasizes that batch files are ideal for automation because they do not require compilation and can run without user interaction. This makes them well-suited for startup operations that must execute consistently every time the system boots or a user logs in.

The Mike Meyers / Mark Soper Lab Manual contrasts batch files with other file types: .sh files are used in Linux and macOS, .msi files are installer packages, and .exe files are compiled programs that may prompt user interaction or security warnings.

Because batch files are native to Windows, scriptable, and commonly used for startup automation, C. BAT is the correct answer.

The AppData folder is located inside a user profile (for example, C:\Users\ < username > \AppData) and is hidden by default in Windows, so users often can’t browse to it unless hidden items are displayed. The correct way to make the folder visible and easy to navigate is to adjust File Explorer Options (Folder Options). Mike Meyers’ Lab Manual explains that the View tab in Folder Options provides Advanced settings where you can “Show hidden files, folders, and drives” because “File Explorer hides them by default.” That directly enables AppData visibility in normal navigation.

The All-in-One guide provides the same workflow: accessing File Explorer Options opens a dialog where the “View options” include the setting to “Show hidden files, folders, and drives,” and it notes hidden extensions and other view behaviors are managed here as well.

Indexing affects search performance, not visibility. Privacy and Ease of Access don’t control hidden folder display. Therefore, configure File Explorer Options (B).

Least effort with correct access control is achieved by assigning permissions to a group and managing membership, rather than editing permissions user-by-user. Mike Meyers states this as a best practice: “ NTFS permissions are assigned both to user accounts and groups, although it’s considered a best practice to assign permissions to groups and then add user accounts to groups instead of adding permissions directly to individual user accounts. ” This reduces administrative overhead: once the group has the correct rights, adding/removing users is simple.

The CompTIA A+ practice rationale reinforces the same: “ Another best practice is to assign permissions to groups rather than users, and make users members of groups … as they change roles or positions.”

This question’s permission goal (“add,” “edit,” but “prevent deletion”) maps to carefully selected rights (for example, allow read/write/modify for needed actions while explicitly denying delete where appropriate), and the cleanest way is implementing that permission set once on a security group . Mapping drives (A) doesn’t enforce permissions by itself, admin rights (C) is excessive, and per-user permissions (D) is the most work.

An in-place upgrade is the fastest and most efficient way to upgrade from Windows 10 to Windows 11 while keeping all user data, applications, and settings intact. This method is often used when the hardware meets Windows 11 requirements and no system reconfiguration is necessary.

A. gpupdate is used to refresh Group Policy settings — unrelated to OS upgrades.

B. Image deployment typically replaces the current OS and may not retain user data unless specifically customized.

C. A clean install requires formatting the drive and starting fresh, which removes all data.

BSOD after driver installation suggests a compatibility issue.Safe Mode allows rollback of driversthat may be causing the crash.

FromTravis Everett – CompTIA A+ All-in-One Exam Guide:

“If a BSOD occurs after a driver update, boot into Safe Mode and roll back to the previous driver version to restore system stability.”

Thepowercfg commandis a built-in utility for controlling power settings including hibernation. It can be used in scripts and does not require domain access.

FromQUENTIN DOCTER - COMPTIA A+ COMPLETE study GUIDE:

“The powercfg command provides granular control of power settings, useful for scripting and configuring systems without Group Policy access.”
