Question: In the Nmf_MRM_Create service operation for creating a media context in an IMS network, what is the purpose of including 'Media Function Specifications' in the Media Termination Descriptor inputs?
Option 1: To specify the QoS (Quality of Service) parameters for the media stream.
Option 2: To define the security setup for the DTLS connection of data channel media flows.
Option 3: To indicate the preferred codec for media processing by the Media Function (MF).
Option 4: To request a specific media function (e.g., DC or AR media function) to be applied to the media stream as required by the application layer.
Explanation: The correct answer is Option 4 because 'Media Function Specifications' are included to specify the type of media function that should be applied to the media stream, as requested by the application layer, influencing how the media stream is handled and processed.
