Question: What action may an Application Server (AS) take when receiving SIP signaling with service interaction information indicating a service should be avoided, based on local policy?
Option 1: The AS must strictly avoid executing the indicated service.
Option 2: The AS will automatically execute the indicated service to test compatibility.
Option 3: The AS ignores all subsequent service requests from the originating AS.
Option 4: The AS may, depending on local policy, take this information into account or ignore it.
Explanation: This correct answer reflects the nuanced handling of service interaction information by an Application Server. It highlights the flexibility given to ASs to make decisions based on local policies when encountering service interaction information in SIP signaling, ensuring compatibility and avoiding potential service disruptions.
