Comprehensive and Detailed Explanation From Exact Extract:

Highmemory usage (97%)suggests the system is overloaded with active processes. The technician should close unneeded applications to free up RAM and improve performance.

FromMike Meyers ' Lab Manual:

“When memory usage is near capacity, close all non-essential programs. This can dramatically improve response time without needing hardware upgrades.”

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 completed configuration:

1. Wireless AP (LAN side)

1. LAN IP: 192.168.10.1

2. Encryption: WPA2 PSK

2. Router (port-forward rule)

1. Allow TCP Any 3389

This forwards inbound RDP traffic (TCP/3389) from the Internet to the Windows PC, enabling Remote Desktop access.

3. Firewall (screened subnet side)

1. LAN IP: 10.100.0.1

4. Device placement

1. PC: place behind the router (where the port-forward rule points).

2. Game console: place on the Wireless AP (so it can use chat and extra services over WPA2 PSK).

3. Firewall: place in front of the screened subnet (with its 10.100.0.1 IP facing that subnet).

The Windows PC is placed in the screened subnet (behind the firewall) for enhanced security. Remote access to this PC requires port forwarding of TCP port 3389 (RDP), which is correctly configured through the router.

The Game Console is placed on the Wireless AP LAN, using WPA2 PSK for a secure wireless connection. Game consoles typically use peer-to-peer chat and online services that require open access without firewall restrictions, which is why the console is not placed behind the firewall.

CompTIA A+ 220-1102 Reference Points:

Objective 3.4: Given a scenario, implement best practices associated with data and device security.

Objective 2.4: Given a scenario, use appropriate tools to support and configure network settings.

Study Guide Reference: CompTIA A+ Core 2 guides recommend using screened subnets (a type of DMZ) for systems needing controlled external access, such as remote desktops, while placing gaming and media devices on less restricted networks for full functionality.

The symptoms suggest abrowser hijacker. Thefirst stepsshould be toremove any malicious extensionsandreset the startup pageto restore normal behavior.

FromAll-in-One Exam Guide:

“Browser hijackers often install as extensions and change homepage settings. Removing these extensions and resetting the startup configuration typically resolves the issue.”

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.”

Comprehensive and Detailed Explanation From Exact Extract:

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.

Comprehensive and Detailed Explanation From Exact Extract:

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.

One of the most common causes for performance degradation on smartphones isstorage or memory overloaddue to excessive apps.Uninstalling unused appsis a basic but effective first diagnostic step.

FromTravis Everett – All-in-One Exam Guide:

“Start troubleshooting sluggish smartphones by clearing unused apps and files before performing advanced diagnostics or resets.”

The correct answer is C. Setting up image deployment for PXE , because PXE (Preboot Execution Environment) allows operating system installations and upgrades to be performed over the network without using removable storage. Since all removable media is disabled for security reasons, PXE-based deployment preserves existing security controls while enabling centralized OS upgrades.

According to the Quentin Docter – CompTIA A+ Complete Study Guide , PXE is commonly used in enterprise environments to deploy or upgrade operating systems at scale. PXE works by booting client machines from a network interface and pulling installation images from a secured deployment server.

The Travis Everett & Andrew Hutz – CompTIA A+ All-in-One Exam Guide explains that PXE is especially valuable when USB drives and external media are restricted. It ensures consistency, reduces human error, and maintains compliance with organizational security policies.

The Mike Meyers / Mark Soper Lab Manual reinforces that copying ISO files locally still requires write access and may violate security baselines. External drives are explicitly prohibited, and hardware tokens are authentication tools—not deployment mechanisms.

Because PXE enables secure, centralized, removable-media-free OS upgrades , it is the most appropriate solution, making C the correct answer.

The correct answer is A. Perform a factory reset , because the symptoms strongly indicate a serious mobile malware infection , potentially including spyware or a trojan installed from an unofficial app store. Random pop-ups, excessive data usage, blocked access to banking apps, and inability to update the OS are classic indicators that malicious software has gained deep system-level access .

According to the Quentin Docter – CompTIA A+ Complete Study Guide , mobile malware installed from unofficial sources can embed itself deeply into the operating system, sometimes gaining device administrator privileges. In such cases, standard remediation steps such as clearing cache or uninstalling apps may be ineffective.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that when a mobile device shows signs of persistent compromise—especially when core OS functions and security-sensitive applications are affected—the recommended first step is to perform a factory reset . This completely wipes user-installed applications and restores the device to a known-good state.

The Mike Meyers / Mark Soper Lab Manual reinforces that changing passwords is important after the device is secured, not before. Contacting support or clearing cache does not remove deeply embedded malware.

Therefore, to immediately address the security threat and regain control of the device, a factory reset is the most appropriate first action , making A the correct answer.
