CompTIA 220-1202 Online Access

The correct answer is B. Task Manager , because Task Manager allows technicians to view, manage, and terminate running processes , including those that are frozen or unresponsive. If an application process is already running but not responding, launching it again will fail until the existing process is stopped.

According to the Quentin Docter – CompTIA A+ Complete Study Guide , Task Manager is the primary Windows tool for troubleshooting application hangs, excessive resource usage, and nonresponsive programs. Technicians can end the task and relaunch the application cleanly.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that Resource Monitor provides detailed performance metrics but is not optimized for quickly terminating frozen applications. Event Viewer logs errors but does not resolve active process issues.

The Mike Meyers / Mark Soper Lab Manual reinforces that Registry Editor should never be used for live application troubleshooting due to the risk of system instability.

Because the issue involves an unresponsive background process , Task Manager is the fastest and safest tool to resolve the problem, making B the correct answer.

The correct answer isVNC (Virtual Network Computing). VNC is a graphical desktop-sharing system that uses the Remote Frame Buffer protocol (RFB) to remotely control another computer. It is platform-independent and widely supported on Linux, which makes it ideal for providinginteractive remote support for a Linux-based operating system. It allows the technician not only to view the remote desktop session but also tocontrol it, fulfilling the need to see and interact with the user’s session.

A. VPN(Virtual Private Network) creates a secure tunnel to a network but doesnot provide desktop sharing or session controlby itself.

C. SSH(Secure Shell) provides secure command-line access to Unix/Linux systems but does not offergraphical desktop interaction, which is a requirement in this case.

D. RDP(Remote Desktop Protocol) is primarily a Microsoft protocol, and although it can be made to work on Linux, it isnot natively supported on legacy Linux systems, and thusless suitablethan VNC in this scenario.

CompTIA A+ 220-1102 Core 2 Objective Reference:

Objective 1.8 – Given a scenario, use features and tools of the operating system.

Under this objective, candidates are expected to be familiar with remote access technologies, includingRDP, SSH, and VNC, and understand their appropriate uses and limitations on different platforms such as Windows and Linux.

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.
