Security process requiring multiple verification methods.

• A. Forensic Analysis
• B. Monitor Threats
• C. Productivity Tools
• D. Multi-factor Authentication

Answer: (D)

Requiring multiple verification methods is about proving a user’s identity with more than one type of credential. This is multi-factor authentication. It uses factors from different categories—something you know (a password), something you have (a token or a smartphone app), and something you are (a biometric). When at least two factors are present, access is granted, making it much harder for someone who steals one credential to gain entry. For example, entering a password and then approving a push notification on a phone is MFA. Other options like forensic analysis focus on investigating what happened after a security event, monitoring threats is about detecting ongoing risks, and productivity tools are software to help work tasks; none of these address verifying identity with multiple methods.
