Quick Answer
The answer is to configure a Safe Links policy. This is correct because Safe Links in Microsoft Defender for Office 365 provides real-time URL scanning and rewriting at the time of click, actively protecting users from malicious links in email by checking each link against threat intelligence feeds and blocking access to newly compromised or phishing sites. On the Microsoft Cybersecurity Architect exam, this question tests your ability to distinguish between the four primary Defender policies: Safe Links for URLs, Safe Attachments for files, anti-spam for bulk mail, and anti-phishing for impersonation attacks—a common trap is confusing Safe Links with anti-phishing, which handles deceptive sender tactics rather than link-level threats. To remember, think of Safe Links as the “click-time guard” that intercepts the URL itself, not the email’s content or attachments. A useful mnemonic is “Links are clicked, attachments are opened”—so Safe Links protects the click, Safe Attachments protects the open.
This SC-100 practice question tests your understanding of design security solutions for infrastructure. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 uses Microsoft Defender for Office 365. You need to design a solution to protect users from malicious links in email. What should you configure?
Anti-spam policy
Why wrong: Anti-spam filters spam, not malicious links.
Safe Attachments policy
Why wrong: Safe Attachments protects against malicious attachments.
Safe Links policy
Safe Links protects against malicious URLs.
Anti-phishing policy
Why wrong: Anti-phishing detects phishing attempts, not specifically links.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Safe Links policy
Option A is correct because Safe Links in Defender for Office 365 scans and blocks malicious links in real time. Option B is incorrect because Safe Attachments is for attachments. Option C is incorrect because anti-spam policies handle spam. Option D is incorrect because anti-phishing policies handle phishing, not links specifically.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
