Choose the single best answer.

  1. A.SMS changes the token’s audience to the wrong API
  2. B.The completed method does not meet the required authentication strength
  3. C.The policy automatically removes the user’s app role
  4. D.Any MFA must satisfy every strength
Show the answer and explanation

✓ Correct answer

  • The completed method does not meet the required authentication strength

Authentication strength restricts allowed methods. Ordinary MFA need not meet phishing resistance; the policy does not inherently remove an app role or change token audience.
