Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.

Correct answer & explanation
✓
Disable the user account.
Disabling the user account is the immediate containment action to prevent further unauthorized access while investigation proceeds. Resetting password alone doesn't stop current session; blocking legacy auth is a broader action that may break legitimate services; MFA is enabling but not immediate containment.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Reset the user's password immediately.
Why it's wrong here
Resetting password does not revoke existing tokens or terminate current sessions, so the attacker may still have access.
✗
Enable Conditional Access to block all sign-ins from that location.
Why it's wrong here
Creating a Conditional Access policy can take time and may not apply immediately; also it doesn't stop the current session.
✓
Disable the user account.
Why this is correct
Disabling the account immediately prevents any further sign-ins and contains the incident while investigation is ongoing.
Clue confirmation

Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
