Question: What is a conformance requirement for a terminal regarding the APN Control List service, as defined by relevant telecom standards?
Option 1: The terminal must always prioritize network-provided APNs over those listed in the EFACL.
Option 2: The terminal can request EPS Bearer activation without checking EFACL if the ACL service is disabled.
Option 3: The terminal shall not request EPS Bearer activation from the network if the APN is not present in EFACL and the ACL service is enabled.
Option 4: The terminal must check EFACL for every EPS Bearer deactivation request.
Explanation: This option correctly reflects a key conformance requirement for terminals regarding the APN Control List (ACL) service. If the ACL service is enabled, the terminal must ensure that any requested EPS Bearer's APN is listed in the EFACL before making the request to the network, ensuring controlled and secure access to network resources based on predefined USIM settings.
