OutSystems Architecture-Specialist-11 Exam - Topic 2 Question 52 Discussion

_API module is for
C) Technical wrapper to expose an API to External consumers, keeping core services system agnostic and supporting multiple versions of the API.
A) Logic to Synchronize data in CS's with an external system. Isolating this logic makes the CS completely system agnostic and it's easier to decouple or replace the external system.
B) A BL becomes a Calculation Engine if it performs complex calculations, (e.g. an invoice calculation engine or an insurance simulator). Engines are usually subject to versions.
D) Reusable Core Services with public entities, actions, and blocks.
E) Isolated Business Logic (Actions) or Core Widgets (blocks), to manage complexity, composition or to have its own lifecycle.

I feel like option A is close, but I also recall that the API module is more about interaction with external systems rather than just synchronization.

I'm a bit confused about the difference between the calculation engine and the API module. Could it be that both have to do with isolating logic?

I remember practicing a question similar to this, and I think option C sounds right because it mentions keeping services system agnostic.

I think the API module is about exposing services to external consumers, but I'm not entirely sure if it's just a technical wrapper or something more.
