Microsoft Edge most commonly blocks “unrecognized” or “potentially unsafe” downloads through Microsoft Defender SmartScreen, which is a reputation-based protection feature integrated into Windows/Edge. When SmartScreen cannot establish trust in a downloaded file (often because the file type is commonly abused or the file has low reputation), it can warn or block the download even if the technician believes the file is legitimate. In this scenario, the technician should adjust SmartScreen settings (rather than disabling antivirus, UAC, or the firewall) to permit the download while keeping other protections intact. This aligns with Windows security management concepts: Windows includes built-in protections (Microsoft Defender and related safeguards) that can be configured through Windows Security, and technicians should tune the specific protection causing the block instead of broadly weakening system security. Also, browser security options are managed from the browser’s Settings area, reinforcing that the correct fix is changing the browser’s download/reputation protection behavior rather than network or privilege controls.

This issue happens when Windows is hiding known file extensions. If extensions are hidden, the user may only be changing the visible name (for example, changing “Document” to “Document.xml”), while the real filename remains something like Document.xml.txt. Windows Explorer then displays “Document.xml,” but file properties still show the true type as Text Document (.txt) because the actual extension at the end is still .txt, and Windows determines file type by that extension. The fix is to show file extensions by turning off the “hide extensions” behavior—i.e., uncheck “Hide extensions for known file types” in File Explorer Options/View settings. Quentin Docter specifically calls out that “Hide Extensions For Known File Types” is commonly changed because seeing extensions is “really handy,” and shows steps to deselect “Hide File Extensions For Known File Types.” The All-in-One guide and Mike Meyers’ Lab Manual both reinforce that you toggle extensions by deselecting “Hide extensions for known file types.”

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.

exFATis the only listed file system that supports both read and write access across Windows, macOS, and Linux (with appropriate drivers). It’s optimized for flash storage and external drives.

FromAll-in-One Exam Guide:

“exFAT is a lightweight file system with cross-platform read/write support, ideal for use on removable drives when compatibility is essential.”
