Question: What is the primary purpose of the N5 and Rx reference points between the SIP core and the 5GS in Mission Critical services over a 5G System?
Option 1: To facilitate voice call setup and teardown for emergency services
Option 2: For authentication, authorization, and accounting (AAA) of mission critical users
Option 3: To enable SMS messaging for group communications among first responders
Option 4: For resource management of MC service sessions, including Quality of Service (QoS) control
Explanation: The correct answer is focused on the management of resources for Mission Critical (MC) services, which includes ensuring appropriate Quality of Service (QoS) levels. This is crucial in 5G systems to guarantee reliable and high-priority communications for emergency or mission-critical scenarios. Options 1 through 3, while potentially related to telecommunications, do not accurately describe the primary purpose of the N5 and Rx reference points as defined by the context of managing MC service sessions.
