SC-200 Respond to security incidents Practice Question
This SC-200 practice question tests your understanding of respond to security incidents. This is a configuration task: choose the command set that satisfies every stated requirement.

After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Your organization has Microsoft Defender XDR enabled. An incident is generated for a user who clicked a phishing link in an email. The analyst needs to automatically disable the user's mailbox for suspicious activity. Which automated action should the analyst configure in a Microsoft Sentinel automation rule?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Run a playbook that uses the Microsoft 365 Defender connector to disable the mailbox.
Option A is correct because disabling the mailbox is a remediation action available in Microsoft 365 Defender. Option B is wrong because deleting the email does not prevent future access. Option C is wrong because blocking the sender IP is not a direct action from Sentinel. Option D is wrong because resetting password is a different action.
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.

Run a playbook that deletes the phishing email from the user's inbox.
Why it's wrong here

Why it's wrong here
Blocking the sender IP is not directly related to disabling the mailbox.
✗
Run a playbook that resets the user's password.
Why it's wrong here
Resetting password is a different action; the requirement is to disable the mailbox.
✓
Run a playbook that uses the Microsoft 365 Defender connector to disable the mailbox.

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.
