How do intrascoped rules differ from extrascoped rules?

Intrascoped rules and extrascoped rules serve distinct functions in traffic management within a specific security policy framework, such as that used by Illumio. Intrascoped rules are indeed tailored to operate within a defined scope—this means that they apply only to the communication between endpoints that are already within that specific scope. These rules help regulate traffic and ensure that interactions are controlled based on the context of that defined scope, offering granular control.

In contrast, extrascoped rules are designed to facilitate traffic from outside the defined scope, which allows specific interactions to occur even when involving endpoints not directly covered by the primary scope. This is essential for accommodating communications that may originate from external sources while maintaining an overall security posture.

Recognizing the characteristics of these rules is critical for effective policy management, as understanding their scopes allows for precise control over how traffic is managed, where it is permitted, and which endpoints are eligible for communication under the policy framework. This differentiation is central to how security policies are structured and enforced, making option C the accurate representation of the differences between intrascoped and extrascoped rules.
