Question 90
Which outcome most clearly shows that the chosen AWS capability meets the stated requirement? A shared administrator password is known by several employees and management wants a second authentication factor.
Explanation
Correct Answer
A stolen password alone is insufficient for the protected sign-in flow. This is the best expected outcome for the stated situation. Multifactor authentication adds a factor beyond a password to strengthen sign-in security. The key business clue is: Look for account takeover risk from compromised passwords. A suitable choice is: Require MFA for applicable privileged identities and replace shared credentials with individual identities. An expected result is: A stolen password alone is insufficient for the protected sign-in flow. Important limitation: MFA lowers risk but does not eliminate phishing and compromised-session attacks.
