Which statement explains why MFA is critical for TA access to sensitive systems?

• A. It logs all user activities.
• B. It adds a second factor beyond passwords, reducing risk from credential theft and strengthening verification.
• C. It eliminates the need for passwords.
• D. It automatically blocks all user accounts after one attempt.

Answer: (B)

Multi-factor authentication strengthens access by requiring more than just a password. For trusted agents accessing sensitive systems, it adds a second verification factor—such as a one-time code from a token or a biometric check—so even if a password is stolen, the attacker still can’t log in. This layered approach significantly reduces risks from credential theft, phishing, and password reuse, providing stronger assurance that the person accessing the system is who they claim to be. MFA doesn’t replace passwords entirely, nor is it primarily about logging activity or automatic account blocking; it’s about adding an extra hurdle that dramatically lowers the chance of unauthorized access.
