Question 110
A security policy owner must resolve this specific case: Remote administrators need a second factor during a supported network access workflow, but policy is configured to validate only a directory password. Which recurring operational control would reduce this risk?
Explanation
Correct Answer
Test external MFA service failures and document secure fail-closed or permitted exception behavior. This control addresses recurrence of the observed failure. The governing behavior is: Multifactor authentication adds proof beyond a single password; placing a password-only AD store in a sequence does not create a second factor. The ongoing acceptance check remains: A pilot access attempt requires and validates the approved second factor, with failed challenges denied.
Incorrect Answers
Test external MFA service failures and document secure fail-closed or permitted exception behavior. The offered choice instead concerns a different principle: Audit overlapping account namespaces before modifying identity-source sequences. Those technical conditions are not interchangeable.
Test external MFA service failures and document secure fail-closed or permitted exception behavior. The offered choice instead concerns a different principle: Expire temporary local users and prevent test identity stores from matching production requests. Those technical conditions are not interchangeable.
Test external MFA service failures and document secure fail-closed or permitted exception behavior. The offered choice instead concerns a different principle: Test SSID and network-device-group conditions in each wireless authorization policy set. Those technical conditions are not interchangeable.
