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

The correct answer is C. Setting up image deployment for PXE, because PXE (Preboot Execution Environment) allows operating system installations and upgrades to be performed over the network without using removable storage. Since all removable media is disabled for security reasons, PXE-based deployment preserves existing security controls while enabling centralized OS upgrades.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, PXE is commonly used in enterprise environments to deploy or upgrade operating systems at scale. PXE works by booting client machines from a network interface and pulling installation images from a secured deployment server.

The Travis Everett & Andrew Hutz – CompTIA A+ All-in-One Exam Guide explains that PXE is especially valuable when USB drives and external media are restricted. It ensures consistency, reduces human error, and maintains compliance with organizational security policies.

The Mike Meyers / Mark Soper Lab Manual reinforces that copying ISO files locally still requires write access and may violate security baselines. External drives are explicitly prohibited, and hardware tokens are authentication tools—not deployment mechanisms.

Because PXE enables secure, centralized, removable-media-free OS upgrades, it is the most appropriate solution, making C the correct answer.

The correct answer is D. Research the attendees’ time zones. Because the colleagues are around the world, the technician should first determine each attendee’s time zone before scheduling. Otherwise, the meeting might be set at an unreasonable or impossible time for some participants. The A+ materials emphasize professional communication, sensitivity, and respecting users’ schedules and circumstances. The All-in-One Exam Guide states that technicians should be culturally sensitive and, when a customer’s schedule or customs affect work, the technician should adapt professionally. Videoconferencing tools are appropriate for this type of meeting; Quentin Docter’s Complete Study Guide explains that videoconferencing software includes features such as calendar invites, call-in numbers, attendee management, screen sharing, and collaboration. However, before configuring software or sending the invite, the technician must know when the meeting can reasonably occur for all global attendees. Dressing appropriately comes later, just before the meeting.

Shoulder surfing is explicitly categorized as a social engineering technique because it relies on human behavior and observation rather than exploiting software flaws or cracking passwords through computation. Quentin Docter defines it directly: “Another form of social engineering is known as shoulder surfing. It involves nothing more than watching someone when they enter their sensitive data,” such as a password or credit card number. Docter also notes that privacy filters can reduce viewing angles, but “privacy filters do not protect you as you are entering a password, since a shoulder surfer will watch your keystrokes,” and the best defense is to “survey your environment before entering personal data.”

The Mike Meyers Lab Manual reinforces the same classification: “Shoulder surfing is another technique for gathering information and gaining unauthorized access… observing someone’s screen or keyboard to get information, often passwords.” Since this is about manipulating or exploiting a person’s situation (being nearby, watching, taking advantage of inattentiveness), it is not a zero-day, evil twin, or brute-force method. Therefore, Social engineering (C) is correct.

User offboarding involves disabling the departing user ' s access to company systems and facilities. Two key tasks typically include:

Deactivating physical access credentials (e.g., key fobs or badges) to prevent unauthorized entry (B).

Suspending or disabling the user’s email account to prevent future use and to retain business communications (D).

A. Quarantining a hard drive is not standard unless malware or legal issues are involved.

C. Purging PII must follow legal retention policies; it ' s not typically an immediate offboarding task.

E. Disabling network ports may be relevant in some cases but is not a standard offboarding step.

F. Blocking MAC addresses is not typical unless the device is considered a security threat.

If the phone works on Wi-Fi but not off Wi-Fi, the most likely issue is that cellular data is disabled (or restricted). This aligns directly with the CompTIA A+ objective language for mobile troubleshooting, which explicitly includes “wireless/cellular data network (enable/disable).” After travel, users often enable airplane mode or disable cellular data to avoid roaming charges, and sometimes forget to re-enable it.

Quentin Docter’s mobile connectivity discussion repeatedly distinguishes Wi-Fi access from cellular connectivity and treats cellular settings as a primary area to verify when Internet access is not available away from Wi-Fi. While data caps/limits could throttle service, they usually don’t make all non-Wi-Fi browsing and email impossible immediately. VPN issues might block some access, but the simplest “most likely” resolution based on the symptom is re-enabling cellular data. Reinstalling the SIM is possible, but again not the first, most likely fix given the scenario framing. Therefore, Enable cellular data (A) is correct.

The correct answer is A. Verify that storage space is available. The question already confirms two major requirements: the laptop has Wi-Fi connectivity and supports the latest update. The next most likely cause is insufficient storage. Quentin Docter’s Complete Study Guide explains that when a mobile OS fails to update, the technician should check compatibility, connectivity, and storage. It specifically states that enough storage space must be available because, during an update, both the current operating system and the upgrade files may need to exist on the device. The Mike Meyers/Mark Soper material also identifies the df command as useful for listing used and available storage space on macOS or Linux systems, showing how important available storage is when diagnosing update and system issues. Airplane mode is unlikely because Wi-Fi was already confirmed. Antivirus scans and unauthorized software checks may be useful later, but storage should be checked next.

BSOD after driver installation suggests a compatibility issue.Safe Mode allows rollback of driversthat may be causing the crash.

FromTravis Everett – CompTIA A+ All-in-One Exam Guide:

“If a BSOD occurs after a driver update, boot into Safe Mode and roll back to the previous driver version to restore system stability.”

The correct answer is C. Private browser . Private-browsing mode is designed to reduce the amount of browsing data stored locally on a system. Quentin Docter’s Complete Study Guide explains that private-browsing mode was created primarily for data privacy while browsing and that its most important feature is that it does not store web browsing data. When the private-browsing session is closed, the browsing data is destroyed. This is useful when a user is temporarily using a shared or loaner computer because it minimizes local browser history, cookies, cached website data, and session traces. Passwordless login changes how the user authenticates but does not minimize browsing data. Secure DNS protects DNS lookups but does not prevent local data storage. Syncing user data would do the opposite of the requirement because it may copy personal browser data, passwords, settings, or history to the temporary computer.

Hardening focuses on reducing default attack surface and removing predictable access paths. Quentin Docter explains that default accounts are risky and highlights that Windows creates a Guest account that “represents a weakness that can be exploited,” so you “should disable all accounts that are not needed, especially the Guest account.” That directly supports option B.

Docter also emphasizes changing defaults as part of hardening: “Changing the default password to a complex password is also a good practice in hardening the device.” That maps to option E (change the default administrator password). These actions reduce common credential-based attacks and limit unauthorized access.

Other options are either unrelated to workstation hardening (remote collaboration tools, virtual assistants) or weaken security (disabling screensavers may remove automatic lock behavior). Thus, the best two hardening steps are disable Guest and change the default admin password.

TheDo Not Disturbsetting in Windows Notification settings allows users to suppress all notification banners and sounds during presentations or video calls.

FromTravis Everett – All-in-One Exam Guide:

“Use Windows ‘Do Not Disturb’ to prevent notifications from interrupting full-screen apps like video conferencing.”
