How can you view more details about completed remediation actions in the History tab of Microsoft Defender portal's AC?

The correct choice highlights that completed actions are indeed accessible in the History tab, allowing users to view remediation actions that have been carried out. When selecting this option, it is essential to recognize that it describes both the visibility of these actions and the specific feature that enables users to undo a selected action. This functionality is critical for security operations analysts, as it provides the ability to revert potentially incorrect remediation decisions, thus enhancing the overall management of security incidents.

Furthermore, the ability to undo a selected action underscores the importance of having control and flexibility when managing security responses in the Microsoft Defender portal. When dealing with security incidents, having access to a robust history of actions taken—along with the option to reverse those actions—can significantly contribute to a more effective incident response strategy.

The other choices provide some context but either do not encapsulate the full capabilities of the History tab or focus on specific aspects that might not fully articulate the complete functionality offered. For instance, while some choices reference viewing additional details or accessing certain features, they do not encapsulate the comprehensive nature of both viewing and undoing actions as clearly as the correct selection does.
