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

Comprehensive and Detailed Explanation From Exact Extract:

In a domain environment, printers are typically deployed via a print server. Users can browse available printers on the server and install them directly.

All-in-One Exam Guidementions:

“In a corporate domain, printers are managed via a centralized print server. Users can select the desired printer from the server’s shared list.”

This is part of the user education step after a security incident to prevent future occurrences.

From Quentin Docter – Complete Study Guide :

“User education and awareness is a crucial part of preventing phishing attacks. After an incident, it is vital to train users on recognizing suspicious messages.” .

The user needs to deliver a project status presentation to external stakeholders , which implies hosting a meeting with screen sharing, invitations, and attendee management. Quentin Docter defines videoconferencing as screen-sharing software that allows more than one person to share screens and includes “additional functionality, such as calendar invite, call-in numbers, and attendee management.” He lists Microsoft Teams, WebEx, Zoom, and GoToMeeting as examples and states these tools “are often used to present ideas and collaborate between groups of people.” That exactly matches presenting to external stakeholders.

The other options don’t fit the requirement: WinRM is a Windows remote management protocol (administration, not presentations), RMM is used by IT providers to manage many systems remotely (not stakeholder presentations), and secure file transfer is for moving files rather than delivering a live presentation. Since videoconferencing platforms commonly provide screen sharing, chat, and meeting controls designed for external audiences, Videoconferencing (C) is the correct software type.

Group Policyis the standard administrative tool for enforcing security and configuration settings across domain-joined systems, including disabling guest accounts.

FromQuentin Docter – CompTIA A+ Study Guide:

“Disabling guest accounts and applying consistent security policies across multiple machines is best achieved through Group Policy on a Windows domain.”

End-user education is crucial after malware removal to prevent recurrence. Teaching safe browsing habits and security awareness completes the remediation cycle.

Mark Soper – Mike Meyers ' Lab Manualstates:

“Educating the user after malware remediation is part of the CompTIA malware response methodology. This includes training on phishing and safe practices.”

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 is D. Hide extensions , because Windows File Explorer hides known file extensions by default, which can cause confusion when renaming files. When extensions are hidden, a user may unknowingly change only the visible filename and not the actual file extension.

The Quentin Docter – CompTIA A+ Complete Study Guide explains that Windows uses file extensions to determine file type associations. If file extensions are hidden, renaming a file from Document.txt to Document.xml may actually result in Document.xml.txt, even though only Document.xml is displayed.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide states that to properly change a file’s extension, users must enable “File name extensions” in File Explorer. This allows the user to see and modify the true extension, ensuring the operating system recognizes the correct file type.

The Mike Meyers / Mark Soper Lab Manual reinforces that options such as indexing, personalization, or formatting do not affect how Windows interprets file types. Only visibility of file extensions allows accurate renaming.

Therefore, disabling the “Hide extensions for known file types” setting is required to correctly change the file type, making D the correct answer.

Background applications can significantly drain a smartphone’s battery, even when the device is idle. A technician should first review which apps are running in the background and consuming power through the battery usage section of the OS. Disabling or restricting power-hungry apps often resolves poor battery life.

A. Storage usage doesn’t significantly affect battery life.

B. End of software support is unrelated to battery performance unless it ' s causing inefficient processes, which would still be secondary.

C. Charger wattage affects charging speed, not battery life after charging.

If internal resources (such as intranet or internal apps) can ' t be accessed but external sites work, this often points to aDNS issue, where the system isn ' t resolving internal domain names correctly.

FromAll-in-One Exam Guide:

“When internet access is functional but internal sites fail to load, the issue usually lies with DNS resolution. Internal resources often require internal DNS servers, which may not be configured correctly.”
