Quick Answer
The correct answer is Safe Links, the Microsoft Defender for Office 365 feature that provides time-of-click protection against malicious URLs. Unlike attachment scanning or anti-malware filters that inspect content at delivery, Safe Links proactively rewrites URLs within email messages and Office documents, so that when a user clicks a link, the system performs a real-time reputation check against the latest threat intelligence. If the URL is determined to be malicious at the moment of the click, access is blocked, and the user is redirected to a warning page. On the SC-900 exam, this question tests your understanding of how Defender for Office 365’s layered protection maps to specific threats—Safe Links is the dedicated defense for malicious URLs, while Safe Attachments handles files, and anti-malware or anti-spam policies address other vectors. A common trap is confusing Safe Links with Safe Attachments; remember that “Links” equals URLs and “Attachments” equals files. For a quick memory tip, think “Click first, check later—Safe Links protects the click.”
