Free Practice Questions for CompTIA 220-1202 Exam

The technician should not disclose information about other customers’ issues, environments, or outcomes because that violates professional confidentiality expectations. Instead, the best response is to explain the general troubleshooting process the technician will follow—such as gathering symptoms, checking logs/connection status, isolating whether the problem is local vs. ISP, testing known-good hardware, and documenting results—without referencing other clients’ specific cases. Quentin Docter emphasizes that as a computer professional you must uphold confidentiality and ensure sensitive information “goes no further,” reinforcing that you should not reveal work-related details to others. The All-in-One guide similarly states that anything you see or are told should be treated as a “personal confidence” and not repeated to customers or others, underscoring why option A is inappropriate. Mike Meyers’ Lab Manual echoes this privacy expectation: treat what you see as confidential and handle customers’ private materials appropriately. Option B dismisses the customer’s concern, and option D is unprofessional and speculative.

Resource Monitor provides real-time monitoring of system performance and resource usage, including CPU, memory, disk, and network usage. It helps technicians identify performance bottlenecks (e.g., high memory or CPU usage) that can cause slowdowns in applications over time without producing crash errors.

A. Reliability history logs application crashes or errors — not helpful if the app doesn’t crash.

B. Computer Management is a broad utility with limited real-time monitoring capability.

D. Disk is too vague — tools like CHKDSK can help with disk errors but not general performance degradation.

Just recognizing the device isn’t enough—audio output must be routed to it manuallyby setting it as the default playback device in sound settings.

FromMark Soper – Mike Meyers ' Lab Manual:

“If audio is still playing through the internal speaker, verify that the Bluetooth headset is set as the default playback device. This can be configured under Windows Sound Settings.”

When an OS is no longer receiving updates, it is generally because it has reachedend of life (EOL), meaning the vendor has ceased support.

FromQuentin Docter – CompTIA A+ Complete Study Guide:

“End-of-life refers to the point when an OS vendor no longer issues updates or support. Systems at EOL pose security risks and must be upgraded or isolated.”

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.” .

Windows doesn ' t natively support many Linux file systems (like ext4).Reformatting to exFATmakes the drive readable/writable on both Linux and Windows.

FromAll-in-One Exam Guide:

“For cross-platform compatibility, exFAT is recommended as it supports large files and is recognized by Windows, macOS, and Linux (with exFAT drivers).”

Windows Helloallows biometric and PIN-based login, which are easier and more user-friendly than passwords.

FromQuentin Docter – CompTIA A+ Complete Study Guide:

“Windows Hello supports biometric authentication and PINs, providing easier and secure access especially for users who have trouble remembering passwords.”

A “utility failure” implies a power interruption (brownout/blackout). The device that prevents an immediate shutdown during an outage is a UPS . Quentin Docter explains that a UPS stores energy in batteries and “if the power fails, the batteries can power the computer for a period of time so that the administrator can then safely power it down.” He further notes UPS devices also protect against “power sags and even power outages” and may work with operating systems to shut down safely and automatically.

Mike Meyers’ Lab Manual echoes the same: a UPS “continues to supply AC power to your computer during both brownouts and blackouts via a battery that is charged from the AC current.”

A surge suppressor is mainly for voltage spikes, not sustained backup power. A redundant PSU helps only if one PSU fails inside the system, and Docter explicitly states it “can’t keep the system up and running if there is a power outage.” Therefore, the best answer is B .

Among the options, threat (end-user) education most directly addresses both preventing malware installation and preventing accidental disclosure of sensitive information, because it changes user behavior—the number one target of many attacks. Quentin Docter emphasizes: “ By far the best prevention of security threats is the education of your end users regarding common threats ,” explaining that the most effective method is teaching users not to open suspicious files and to open only those they’re reasonably sure are malware-free. Docter adds that trained users can better identify Trojans and phishing scams and should also learn guidelines for protecting sensitive information and recognizing social engineering threats.

Docter also states clearly that even when antimalware tools exist, “ user education is much more effective ” in preventing certain notification-based and trick-based malware installs. While Secure Boot, firewalls, and email gateways are valuable technical controls, they don’t cover the broad human-risk dimension of both malware installs and sensitive data disclosure as effectively as education/training. Hence B 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”.
