Question: What is the primary outcome when a Network Function (NF) invokes the `Nmf_MRM_Delete` service operation towards the Media Function (MF) in an IP Multimedia Subsystem (IMS)?
Option 1: Creation of a new media stream within an existing media context.
Option 2: Modification of an existing termination's parameters within a specified media context.
Option 3: Deletion of a specified media context resource, including all its associated terminations and media streams.
Option 4: Suspension of all media contexts temporarily for system maintenance.
Explanation: The `Nmf_MRM_Delete` service operation is specifically designed for the deletion of a particular media context resource. This operation encompasses the removal of not just the media context itself but also all existing terminations and media streams associated with it, ensuring a comprehensive cleanup. This aligns with efficient resource management within the IMS infrastructure, preventing unnecessary resource occupation.
