Smallest example: the smallest Inter-Service Communication micro example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Inter-Service Communication (micro).
From the example next to this theory: Synchronous REST vs asynchronous messaging.
Trap: only saying “Inter-Service Communication micro” with no example. Fix that before you talk about advanced Spring.
Viva: what is Inter-Service Communication (micro)? Then show the smallest Inter-Service Communication micro example you can type. Then name the trap.
