What needs to be updated to enable the Core Service Detector?

To enable the Core Service Detector, the correct adjustment is to update the configuration in the runtime environment file, specifically by setting core_services_enabled = true in the runtime_env.yml. This configuration file plays a crucial role as it defines various parameters that control the behavior and functionality of the Illumio environment, including the activation of core services.

When this parameter is set to true, it signals to the Illumio platform that the Core Service Detector should be active. This detection capability is fundamental for monitoring and mapping service dependencies and ensuring that the right policies are being applied effectively across the environment.

Other options presented do not reflect the appropriate mechanism for enabling the Core Service Detector. For instance, toggling a boolean value specific to core services activation represents an overly simplified and potentially incorrect approach, as it doesn't relate directly to the expected configurations found within the runtime_env.yml. Additionally, the mention of firewall settings implies a security aspect that, while important, does not directly pertain to the specific configuration required for the detector. Thus, updating the runtime environment file is essential for the proper functioning of the detector as part of Illumio's policy management framework.
