Pass the CompTIA A+ 220-1202 Questions and answers with CertsForce

The correct answer is B. Turn off notifications in the browser, because the described behavior matches browser notification abuse, not traditional pop-ups. Modern browsers allow websites to request permission to send notifications. If a user previously allowed notifications from a retail site, the site can continue sending onscreen alerts even when pop-up blockers are enabled.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, browser notification permissions are separate from pop-up blocking settings. Pop-up blockers prevent new browser windows or tabs from opening, but they do not block push notifications that were previously approved by the user. These notifications can persist long after visiting a site.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that one of the first troubleshooting steps for repeated browser messages is to review and disable site notification permissions. This directly targets the root cause without affecting browser configuration or user data.

The Mike Meyers / Mark Soper Lab Manual reinforces that resetting or reinstalling the browser is an excessive step unless configuration corruption is suspected. Clearing cache removes stored files but does not revoke notification permissions.

Because the messages originate from previously allowed browser notifications, the most appropriate and targeted fix is to disable notifications in the browser, making B the correct answer.

Before any change is implemented, it must bedocumentedas part of change management procedures. This ensures transparency, review, and tracking.

FromQuentin Docter – CompTIA A+ Complete Study Guide:

“Documenting a change is the first step in change management. This includes defining the scope, purpose, impact, and implementation plan before approval or scheduling.”

The correct answer is D. Connect a wrist strap to a metal frame, because this action directly prevents electrostatic discharge (ESD), which is one of the most common causes of accidental hardware damage during device disassembly. Even when a device is powered off, static electricity stored in the technician’s body can discharge into sensitive components such as RAM, CPUs, and system boards.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, the most effective way to prevent ESD is to equalize electrical potential between the technician and the device. An ESD wrist strap, when connected to a grounded metal surface such as a computer chassis, safely dissipates static electricity before it can damage components.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that while antistatic mats and bags are useful, they are secondary controls. The wrist strap provides continuous grounding throughout the repair process, whereas mats and bags only protect components when they are placed on or inside them.

The Mike Meyers / Mark Soper Lab Manual reinforces that working on plastic surfaces does not guarantee grounding, and placing components in antistatic bags is something done after removal, not immediately after powering down.

Therefore, once the device is turned off, the next and most important step is to connect a wrist strap to a metal frame, making D the correct answer.

The correct answer is B. exFAT, because exFAT (Extended File Allocation Table) is designed to provide cross-platform compatibility between Windows and macOS while supporting large files and large storage devices. When an external hard drive must be readable and writable by both operating systems without additional drivers or configuration, exFAT is the preferred choice.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, exFAT was developed to overcome the limitations of FAT32, such as file size and volume size restrictions, while maintaining broad operating system support. Both Windows and macOS include native support for exFAT, making it ideal for removable storage devices.

The Travis Everett & Andrew Hutz – CompTIA A+ All-in-One Exam Guide explains that NTFS is fully supported on Windows but only has limited or read-only support on macOS by default. APFS is Apple’s proprietary filesystem and is not natively supported by Windows. XFS is a Linux filesystem and is incompatible with both Windows and macOS without third-party tools.

The Mike Meyers / Mark Soper Lab Manual reinforces that for external drives shared across platforms, exFAT offers the best balance of compatibility, performance, and simplicity.

Therefore, exFAT is the best filesystem choice, making B the correct answer.

Comprehensive and Detailed Explanation From Exact Extract:

Multifactor authentication (MFA) is considered one of the most effective security measures for cloud environments. It requires users to verify their identity using two or more factors (e.g., password + phone app code), making it significantly harder for external attackers to gain access, even if the primary password is compromised.

B. Encryption is important for data protection but doesn’t prevent unauthorized logins.

C. Backups protect against data loss but don’t stop breaches.

D. Strong passwords are helpful but can still be phished or cracked — MFA adds a critical extra layer.

The correct answer is A. .app, because macOS applications packaged as .app files are typically self-contained application bundles. This means that all required application files are stored within a single directory that appears as one file in Finder. When the .app file is moved to the Trash, the application is effectively removed from the system.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, macOS applications are commonly distributed as .app bundles, allowing for simple installation and removal. This design contrasts with Windows, where applications often install files across multiple directories and require uninstallers.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that dragging a .app file to the Trash is generally sufficient to uninstall the software, although some applications may leave behind preference files or caches. However, from an exam perspective, .app is the only option that supports this uninstall behavior.

The Mike Meyers / Mark Soper Lab Manual further clarifies that .msi and .exe are Windows formats, .rpm is used by Linux package managers, and .pkg installers often install system-wide components that require a formal uninstallation process.

Because .app files support simple drag-to-trash uninstallation, A is the correct answer.

The correct answer is D. cp, which is a core Linux command used to copy files and directories. File management in Linux is performed primarily through command-line utilities, and cp is one of the most fundamental commands for this purpose.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, Linux administrators frequently use commands such as cp, mv, rm, and ls to manage files. The cp command allows users to copy files between directories or locations and supports options for recursive copying and permission preservation.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide highlights that Linux file management commands differ significantly from Windows equivalents. While Windows uses robocopy and xcopy, Linux relies on simpler, built-in commands like cp.

The Mike Meyers / Mark Soper Lab Manual further explains that curl is used for transferring data over network protocols, not for managing local files. Commands such as robocopy and xcopy are Windows-specific and not available in standard Linux environments.

Because the question asks specifically about managing files in Linux, and cp is a native Linux file-management command, D is the correct answer.

The correct answer is A. Reinstalling the application, because the issue appears to be application-specific rather than system-wide. The problem only affects one game, the operating system is fully updated, and there are no storage constraints. These indicators strongly suggest corrupted application data or a faulty app installation.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, when a single application crashes repeatedly, the first recommended troubleshooting step is to remove and reinstall the app. This clears corrupted files, resets application settings, and ensures the latest compatible version is installed.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide emphasizes that factory resets should only be used as a last resort, as they are disruptive and erase user data. Disabling background applications may help performance issues but does not typically resolve persistent crashes tied to one specific app.

The Mike Meyers / Mark Soper Lab Manual further clarifies that date and time misconfiguration usually affects authentication or certificate validation, not game stability.

Because the symptoms are isolated to a single application and basic system factors have already been ruled out, reinstalling the application is the most appropriate first troubleshooting step, making A the correct answer.
