Question: In the context of Mission Critical (MC) services support in Isolated Operation for Public Safety (IOPS) mode, following a backhaul failure, what is the nature of the terminology used for functional entities within the supporting functional model?
Option 1: It implies a specific physical implementation based on traditional client-server architecture.
Option 2: It suggests a virtualized environment where clients and servers are dynamically allocated.
Option 3: It does not imply a specific physical implementation of a functional entity, allowing for flexibility.
Option 4: It mandates a cloud-based infrastructure for all client-server interactions.
Explanation: The correct answer is Option 3 because terminology like 'client' and 'server' is used in a way that doesn’t imply specific physical implementations of functional entities, allowing flexibility in deployment (e.g., same device, different devices, or virtualized), emphasizing logical roles over physical constraints.
