Which feature provides an extra verification step for access?

• A. Safe Mode Protection
• B. Anti-Tamper Protection
• C. Cache Computer
• D. Two-Factor Authentication

Answer: (D)

Extra verification for access means requiring a second form of proof beyond a password. Two-Factor Authentication achieves this by demanding a second factor after you enter credentials, such as a code from an authentication app, a hardware token, or a biometric confirmation. This makes it much harder for someone who only knows the password to gain entry, because the second factor is needed too. In practice, you might enter your password and then approve a login on your phone or enter a short, time-limited code from an authenticator.

The other features are about protection or device state rather than adding a second proof of identity. Safe Mode Protection relates to starting the system in a safe environment, Anti-Tamper Protection guards against changes to the software, and Cache Computer doesn’t address verification at access time. So, Two-Factor Authentication is the feature that provides an extra verification step for access.
