A) It encrypts all user data stored on a device, making it unreadable to unauthorized parties.
B) It requires users to provide two or more distinct verification methods, significantly increasing security against unauthorized access.
C) It automatically backs up all user files to a secure cloud service, preventing data loss from device failure.
D) It monitors network traffic for malicious activity and blocks suspicious connections in real-time.
Explanation
Multi-Factor Authentication (MFA) enhances security by requiring users to provide two or more different types of credentials (e.g., something you know like a password, something you have like a phone, something you are like a fingerprint) before granting access, making it much harder for attackers to gain unauthorized entry even if they steal one credential.
