Question: In the Mission Critical (MC) services architecture over 5G Systems, what is a key characteristic of how each plane operates in relation to other planes?
Option 1: Each plane operates independently, managing its own identities and security, with the option to request services from other planes as needed.
Option 2: Each plane operates dependently, always requesting and providing services simultaneously with all connected planes.
Option 3: Each plane is strictly a client or server, never both, and must use the security mechanisms of a designated server plane.
Option 4: Each plane's functionality is determined by a central orchestrator plane that dictates service requests and provisions.
Explanation: This is correct because, according to the MC services architecture, each plane indeed operates independently, handling its own identities and security while having the flexibility to request services from other planes when necessary.
