Question: What is the primary purpose of QoS monitoring/assurance in the 5G system for services like URLLC, V2X, and vertical automation?
Option 1: To guarantee the required Quality of Service (QoS) from the network.
Option 2: To provide sufficient monitoring information as input for diagnosis features.
Option 3: To prioritize traffic for critical communications over non-critical ones.
Option 4: To optimize network resource allocation based on user behavior.
Explanation: The primary purpose of QoS monitoring/assurance in the 5G system is to guarantee the required Quality of Service (QoS) from the network, especially for services like URLLC, V2X, and vertical automation that mandate specific QoS guarantees. This ensures that applications and application servers are notified in a timely manner if the network cannot meet these requirements due to issues such as increased latency or packet error rates caused by interference.
