Question: What does the presence of `NBIFOM_SUPPORTED (1)` value in the NBIFOM-Support AVP indicate about the NBIFOM procedure for the IP-CAN session?
Option 1: The UE and access network do not support NBIFOM procedures.
Option 2: The PCRF authorizes the application of NBIFOM to the IP-CAN session.
Option 3: The PCEF is required to initiate NBIFOM procedures immediately.
Option 4: The IP-CAN session will automatically switch to a different mobility management protocol.
Explanation: When the `NBIFOM_SUPPORTED (1)` value is included in a CCA command from the PCRF to the PCEF, it signifies that the PCRF grants authorization for applying NBIFOM to the IP-CAN session, highlighting the PCRF's role in controlling network policies, including mobility management aspects like NBIFOM.
