- A
Create an anti-spam policy to block the sender's domain.
Why wrong: Anti-spam policies filter based on sender, not specific URLs.
- B
Create a Safe Links policy and add the malicious domain to the blocked URLs list.
Safe Links policies can block URLs at click time, protecting users.
- C
Create an anti-malware policy to block the attachment type.
Why wrong: Anti-malware policies scan attachments, not links.
- D
Add the sender's domain to the Tenant Allow/Block List.
Why wrong: Tenant Allow/Block List blocks senders or domains, not URLs.

SC-200 Respond to security incidents Practice Question
This SC-200 practice question tests your understanding of respond to security incidents. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 company uses Microsoft Defender for Office 365. A user reports receiving a phishing email that bypassed the default policy. The email contains an external link to a credential harvesting site. You need to block similar emails in the future. What should you do?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a Safe Links policy and add the malicious domain to the blocked URLs list.
The phishing email contains a link to a credential harvesting site, so the most direct way to block similar emails in the future is to use a Safe Links policy. Safe Links proactively scans and blocks URLs at time of click, and you can add the malicious domain to the blocked URLs list to prevent users from accessing that site. This addresses the specific threat vector (malicious URL) rather than the sender's domain or attachment type.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
Create an anti-malware policy to block the attachment type.
Why it's wrong here

- ✗
Add the sender's domain to the Tenant Allow/Block List.
Why it's wrong here
Tenant Allow/Block List blocks senders or domains, not URLs.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse the Tenant Allow/Block List (which is for sender/domain/IP blocking) with the Safe Links blocked URLs list (which is for URL-level blocking), leading them to choose option D instead of B.
Detailed technical explanation
How to think about this question
Safe Links in Defender for Office 365 uses URL detonation and reputation checks at the time of click, and the blocked URLs list is a tenant-level block that applies to all users. Under the hood, Safe Links wraps URLs in a Microsoft-owned proxy (e.g., https://nam01.safelinks.protection.outlook.com) and checks the destination against the blocked URLs list before allowing the redirect. In a real-world scenario, if the attacker uses a different sender domain but the same credential harvesting URL, the Safe Links policy will still block the link, whereas sender-based blocks would fail.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
