What prerequisite must be met when assigning devices to an ADOM?

When assigning devices to an ADOM (Administrative Domain) in FortiAnalyzer, the prerequisite that must be met is that the firmware version must be selected. ADOMs are used to manage and segregate log data from multiple Fortinet devices, and they require the proper firmware version to ensure compatibility and proper functionality. This is essential because different firmware versions may introduce various features or changes that could affect how log data is processed, displayed, or managed within that ADOM.

The selection of the correct firmware version ensures that the FortiAnalyzer can effectively communicate with the devices in the ADOM, manage their logs properly, and apply the intended policies or configurations. Without this step, you could run into issues where logs are not collected or interpreted correctly due to version mismatches.

Other factors, such as device type and network configuration, may be important for overall network topology and management, but they do not serve as foundational prerequisites for assigning devices to an ADOM in the context of FortiAnalyzer.
