Question

You have 1,000 on-premises Windows 11 Pro devices that are onboarded to Microsoft Defender for Endpoint. You have a Microsoft 365 subscription that uses Microsoft Defender XDR. You identify that an attacker performed the following actions on a device:

  • Modified the filesystem path of a registry-based antivirus exclusion
  • Downloaded a malicious file to the file system path

You initiate a live response session on the device. You need to undo the registry change. Which command should you run?

Options

  • Aremediate
  • Bregistry
  • Cscan

Explanation

In a Microsoft Defender for Endpoint live response session, the remediate command is used to undo or reverse malicious changes on a device, including registry modifications. In this scenario, the attacker modified a registry-based antivirus exclusion path; running remediate targets the identified threat artifact and can restore the registry key to its original state. The registry command (B) is not a valid live response command. scan (C) initiates an antivirus scan but does not undo registry changes. analyze (D) is used to run deep analysis on a file, not to remediate registry changes.
