After installing a Microsoft Defender for Identity sensor, what is the next step to finalize its configuration?

Launching the Microsoft Defender for Identity portal to configure sensor settings is the correct step following the installation of a Microsoft Defender for Identity sensor. This portal is where you can finalize the configuration of the sensor, ensuring it is set up correctly for your organization's security needs.

Once the sensor is installed, the portal allows you to tailor various settings such as data acquisition parameters and notification settings. This step is essential as it enables the effective operation of the sensor, which will monitor for suspicious activities and provide insights into potential security threats.

Other options may involve important tasks, but they are not the immediate next step needed to finalize the configuration of the sensor. While checking event logs might confirm installation success, it does not configure the sensor settings. Updating the sensor is an important operational task but typically happens less frequently and not right after installation. Similarly, rebooting the domain controller is generally unnecessary for the sensor to function, as the installation process should already initiate the sensor without needing a restart.
