What is the role of the glide.sys.domain.enabled property?

The glide.sys.domain.enabled property is primarily associated with enabling or disabling domain separation within the ServiceNow platform. When this property is set to "true," it facilitates data separation across different domains, which is essential for organizations that operate with multiple tenants or require isolation of data across various departmental or subsidiary domains. This capability helps ensure that users in one domain cannot inadvertently access the data of another domain, thus maintaining data security and compliance standards.

The other options provided do not accurately capture the functionality of this property. For instance, controlling user access levels or managing domain user roles is typically handled through other security mechanisms and configuration settings within the platform. Tracking changes in company domains is a different function that doesn't relate directly to the domain separation features enabled by this specific property.
