220-1202 Exam Dumps - CompTIA A+ Questions and Answers

The Local Users and Groups Manager (lusrmgr.msc) is the utility for managing user accounts, including renaming the default Administrator.

From Quentin Docter – Complete Study Guide:

“The lusrmgr.msc snap-in allows renaming and managing local user accounts, including the default administrator.” .

When a system begins randomly crashing after a hardware change (installing a GPU) and the correct vendor driver update does not resolve it, the best next troubleshooting step is to collect evidence about what is failing. Windows records crash details, driver faults, and unexpected shutdowns in Event Viewer (System/Application logs) and related reliability tools. Quentin Docter specifically states that Event Viewer should be the first place you look when the solution is not evident because applications and the OS often create log entries that help verify operation and diagnose problems. These logs can reveal whether the crash is tied to a display driver fault, power/kernel events, or another subsystem. Docter also notes you can often find more information about application crashes by reviewing the Application log, and for instability/shutdown patterns you “start combing through the logs” in Event Viewer to determine whether the system lost power or crashed. Mike Meyers adds that Event Viewer is the tool used to read and understand Windows logs (Application/System/Setup/Security) for diagnosing what’s happening on a system.

Event Viewer is the best tool to analyze the root cause of service failures in Windows. It provides detailed logs from system processes, including errors, warnings, and crash reports related to services and applications. When a service starts and stops unexpectedly, Event Viewer will often record the cause, such as dependency failures or access violations.

B. Task Manager shows active processes but doesn ' t retain logs or causes of failure.

C. Internet Options is used for configuring browser settings, not troubleshooting services.

D. Process Explorer is powerful but more suited for live monitoring and detailed process trees, not post-failure log analysis.

The correct answer is D. Continuity. Continuity is an Apple ecosystem feature category that allows Apple devices to work together, such as moving activity between devices or integrating nearby Apple hardware. Among the choices, it is the feature most likely to rely on short-range wireless communication such as Bluetooth, often along with Wi-Fi and iCloud. The A+ materials identify Bluetooth as a personal-area-network technology used for nearby device communication, pairing, and synchronization. The Mike Meyers/Mark Soper material also explains that mobile devices commonly expand and communicate wirelessly through Bluetooth with nearby accessories and devices. Terminal is a command-line interface, not a Bluetooth feature. Gestures are touchpad or touchscreen motions used for input. Mission Control is a macOS interface feature for viewing open windows and desktops. Continuity is the only listed feature that strongly depends on communication between nearby Apple devices.

When a Windows service suddenly stops and then fails to start manually, one of the first places to confirm why it cannot start is the service logon context. A very common root cause is that the account configured on the service cannot authenticate anymore—often because the password changed or the account is locked. Quentin Docter notes that if the service fails due to misconfiguration, “the most likely cause is the user account the service is configured to start with,” and you should ensure “the user account is not locked out.” This aligns with standard service troubleshooting: check Event Viewer (Service Control Manager events) for login failures, then validate the service’s Log On tab configuration and the account state.

The All-in-One guide also reinforces validating services via the Services console and correcting service settings when services fail to start.

Therefore, the best cause given the options is that the service account is locked out (C).

A cable run under a carpet is vulnerable to compression, bending, and repeated physical stress from foot traffic, which can damage the cable jacket, distort the twists, loosen terminations, or partially break conductors—often showing up as intermittent connectivity. Quentin Docter notes that on a wired network, “other wired issues can include bad or poorly connected cables,” and you should check cabling and connections as a cause of intermittent problems. Putting a cable where people walk on it increases the chance it becomes “bad” over time or develops poor connections, producing the intermittent symptoms described in the answer option.

From a safety/professional practice perspective, Mike Meyers emphasizes that unmanaged cables are “dangerous tripping hazards” and that in business environments cables should be “carefully tucked away… or placed under cable runners,” using “proper cable management.” While that supports hazard reduction, the best reason in this question’s choices focuses on network reliability: repeated walking over the cable can cause intermittent issues. So the correct answer is D.

To display a file’s contents in Linux, the standard command is cat. Quentin Docter states: “Sometime you just need to view the contents of a file. To view the contents of a file, use the cat command,” and shows an example cat /etc/hosts displaying the file output. He also lists essential Linux commands and explicitly defines cat as: “Displays the contents of a file.”

The other options do not meet the requirement: chmod changes file permissions, ls lists directory contents (or file names), and sudo runs a command with elevated privileges—none directly display a file’s contents by themselves. A+ also expects you to know that cat can do more than display; it can concatenate files and redirect output, but for this question the key function is simply viewing a file.

Therefore, the correct command is cat (B).

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.

The 3-2-1 backup rule is specifically about number of copies, diversity of media, and offsite storage. “2” in 3-2-1 means using two different types of media. The All-in-One guide states the rule plainly: “keep at least three copies of your data on at least two different types of media… and store at least one copy offsite.” Mike Meyers’ Lab Manual repeats the same definition word-for-word, emphasizing two different media types and one off-site copy.

Quentin Docter explains the same method and gives an example: original data plus an on-site backup, plus “a third copy… off site,” such as backing up to the cloud.

Given the options, only D directly satisfies the “two different media” requirement. Option C contradicts the offsite requirement, option B invents a testing interval not defined by 3-2-1, and option A is about backup types rather than the core 3-2-1 rule. Therefore D is correct.

When an OS reaches its end of life (EOL), it no longer receives updates or support, including critical security patches.

From the Quentin Docter Study Guide:

“End-of-life means the manufacturer no longer supports the OS with updates or security patches, which exposes systems to vulnerabilities unless upgraded”.

All-in-One Exam Guide adds:

“End-of-life notifications serve as a final warning that continued use of the OS will be insecure and unsupported. It’s crucial for administrators to plan migration”.
