Question: What takes precedence over the default configuration at the Charging Transfer Function (CTF) regarding offline charging information when using the Ro interface?
Option 1: The last update of the CTF's default configuration
Option 2: Information contained within the Offline-Charging Attribute Value Pair (AVP)
Option 3: Settings defined in the CCA for online charging only
Option 4: Standard network-wide offline charging policies
Explanation: The correct answer is Option 2 because, according to the specifications, when the Offline-Charging AVP is used on the Ro interface by the Online Charging System (OCS) to communicate with the CTF, the information contained within this AVP takes precedence over the default configuration at the CTF. This ensures dynamic control over offline charging mechanisms based on the OCS's directives.
