How can Conditional Access App Control ensure downloaded documents during risky sessions are protected?

Conditional Access App Control is designed to safeguard sensitive data, especially during high-risk user sessions. The correct choice highlights that it requires all downloaded documents to be labeled and protected with Azure Information Protection.

When documents are labeled and protected through Azure Information Protection, they are assigned specific security classifications that determine the permissions and access controls associated with them. This ensures that even if a file is downloaded during a risky session, it retains its security features. The protection can include restrictions on sharing, editing, and printing, depending on the sensitivity level assigned to the document.

This method helps to maintain the confidentiality and integrity of the data, limiting risk exposure especially in environments where user behavior may be compromised or where the security posture is uncertain. As a result, organizations can maintain greater control over sensitive information, ensuring that it cannot be exploited, even if it is downloaded by a user whose access is deemed risky at that moment.

In contrast, the other options do not provide the same level of comprehensive protection or might not be applicable for all scenarios related to document handling and security in risky sessions.
