CompTIA Updated 220-1102 Exam Questions and Answers by hawwa

Comprehensive and Detailed In-Depth Explanation:

Passwords provide the highest level of security because they cannot be bypassed using biometric spoofing techniques.

A. Face – Can be fooled with 2D images (on some devices).

B. Swipe – Very weak security.

D. Fingerprint – More secure than face/swipe but can still be faked.

In this case, abnormal behavior after opening a suspicious email suggests malware might have infected the device. A full factory reset is recommended to remove any persistent malware, especially when a restart does not resolve the issue. Deleting the email or reinstalling the browser will not remove the malware already on the device.

Cross-site scripting (XSS) (Option C) allows attackers to inject malicious scripts into web pages viewed by users. When the user visits the compromised site, the script runs in the user's browser, potentially allowing the attacker to steal data or perform unauthorized actions. XSS is a common vulnerability in web applications that allows code execution.

DoS (Option A) disrupts services but doesn't involve executing code on a user's device.

Spoofing (Option B) involves impersonating another device or user but doesn't execute code.

SQL injection (Option D) attacks a database and is unrelated to executing code on the user's computer.
