Question 100
A high-value finance app accepts SMS authentication even though its risk policy requires phishing-resistant MFA. The administrator proposes: Configure a supported phishing-resistant authentication strength in Conditional Access for the app. Which result most directly proves the proposed change worked?
Explanation
Correct Answer
The administrator plans 'Configure a supported phishing-resistant authentication strength in Conditional Access for the app.' to correct the fact that any MFA method does not necessarily satisfy a phishing-resistant authentication requirement. The direct acceptance evidence is A pilot login with a supported security key succeeds while an SMS-only credential cannot satisfy the strength. This observation is linked to this change's intended outcome.
Incorrect Answers
A confirmed exposed account triggers approved credential remediation and protected reauthentication. However, that result would not establish the required outcome: a pilot login with a supported security key succeeds while an SMS-only credential cannot satisfy the strength.
A pilot risk event maps to the documented challenge or investigation action. However, that result would not establish the required outcome: a pilot login with a supported security key succeeds while an SMS-only credential cannot satisfy the strength.
A simulated policy lockout leaves a monitored emergency administrator able to restore correct access. However, that result would not establish the required outcome: a pilot login with a supported security key succeeds while an SMS-only credential cannot satisfy the strength.
