NEW QUESTION # 55
Which of the following is the quickest way to move from Windows 10 to Windows 11 without losing data?
Answer: D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
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.
Reference:
CompTIA A+ 220-1102 Objective 1.4: Given a scenario, use appropriate Microsoft operating system installation methods.

NEW QUESTION # 56
A technician needs to provide remote support for a legacy Linux-based operating system from their Windows laptop. The solution needs to allow the technician to see what the user is doing and provide the ability to interact with the user's session. Which of the following remote access technologies would support the use case?
Answer: C
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
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 offer graphical 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.
NEW QUESTION # 57
The screen of a previously working computer repeatedly displays an OS Not Found error message when the computer is started. Only a USB drive, a keyboard, and a mouse are plugged into the computer. Which of the following should a technician do first?
Answer: B
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
An "OS Not Found" error typically indicates that the computer is attempting to boot from a drive that doesn't contain a valid operating system or bootable partition. The presence of a USB drive might be confusing the boot order. Therefore, the first step a technician should take is to verify and adjust the boot sequence in the system's firmware (BIOS or UEFI). It's possible that the USB drive is being prioritized over the internal hard drive, which may cause the system to miss the OS entirely.
A: Running data recovery tools is premature before confirming boot order.
B: Repartitioning the disk would destroy existing data-this should not be done until confirmed the OS is actually missing.
D: Switching between UEFI and BIOS (legacy mode) might help in rare cases, but it is not the first step in standard OS boot issue troubleshooting.

NEW QUESTION # 58
Which of the following filesystem types does the Linux OS use?
Answer: B
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
The ext4 (Fourth Extended Filesystem) is the most widely used default filesystem in modern Linux distributions. It is designed for high performance, scalability, and reliability, and is supported by all mainstream Linux kernels.
A: exFAT is used for cross-platform external drives, not native Linux systems.
B: APFS is Apple's proprietary filesystem for macOS and iOS.
D: NTFS is the default filesystem for Windows, not Linux.
Reference:
CompTIA A+ 220-1102 Objective 1.9: Identify common features and tools of the Linux client/desktop OS.

NEW QUESTION # 59
A user recently installed an application that accesses a database from a local server. When launching the application, it does not populate any information. Which of the following command-line tools is the best to troubleshoot the issue?
Answer: A
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
The scenario involves an application that should retrieve data from a local database server but is failing to do so. This likely indicates a problem in communication between the application and the database server (such as a network issue, port misconfiguration, or service unavailability). The correct troubleshooting approach involves testing the network/service connectivity between the client and the database.
Let's examine the options:
* A. ipconfig:This command displays IP configuration details for Windows systems, such as IP address, subnet mask, and default gateway. While useful for diagnosing general networkissues, it does not test service connectivity or the availability of a specific application port/service.
* B. nslookup:Used to query DNS servers to resolve domain names to IP addresses. However, since the question references a local server (likely accessed via IP or static hostname), DNS is probably not involved. Also, it does not test application/service availability.
* C. netstat:Displays active TCP connections, listening ports, and routing tables. It helps determine whether the local system is listening for or maintaining any network connections, but it does not initiate a connection to test availability. It's diagnostic but not interactive for service testing.
* D. curl:This is the most appropriate tool for this scenario. curl is used to test connectivity to services over protocols like HTTP, HTTPS, FTP, and more. If the application retrieves data via a web interface or API (common in database-driven applications), curl can be used to test if the application can successfully reach and retrieve data from the server. It provides immediate, testable feedback on whether the server and service are available and responsive.
Example usage:
curlhttp://localhost:8080/api/data
This command would test whether a local server's application programming interface (API) is available and responding on port 8080.
CompTIA A+ 220-1102 Reference Points:
* Objective 2.4: Given a scenario, use appropriate tools to troubleshoot and support Windows OS issues.
* Objective 3.3: Use appropriate tools to troubleshoot and resolve issues.
* The CompTIA A+ Core 2 study guide references curl as a useful command-line utility for testing connectivity and troubleshooting application access to services.
