Which items make up zone configuration in an application-aware firewall?

In an application-aware firewall, the core components of zone configuration are the source zone, destination zone, and zone pair. The source zone identifies the origin of traffic, while the destination zone specifies where the traffic is headed. A zone pair defines the directional relationship between a source zone and a destination zone, allowing you to apply specific security policies (like firewall rules) to traffic flowing between those two zones. Interface zones are incorrect because interfaces are assigned to zones, but "interface zone" is not a distinct configuration item for the firewall logic itself. Similarly, while a destination zone is crucial, "interface zone" is not a separate component alongside it.
