Question: Under what condition does the Access and Mobility Management Function (AMF) include the Back-off timer value Information Element (IE)?
Option 1: When the Payload container type IE is set to "Multiple payloads" and the Payload container IE is included.
Option 2: When the Payload container IE is included and the Payload container type IE is not set to "Multiple payloads".
Option 3: When the AMF receives a request from the User Equipment (UE) to establish a new connection.
Option 4: When the AMF needs to release resources allocated for a specific UE.
Explanation: The correct answer is Option 2 because, according to the specification, the AMF includes the Back-off timer value IE when the Payload container IE is included and the Payload container type IE is not set to "Multiple payloads". This condition ensures that the back-off timer value is only sent in specific scenarios where it is necessary.
