I practiced a question similar to this, and I feel like establishing the Organizational Model is crucial, but I can't recall if it's in the Preliminary Phase.
Okay, let's see. The fact table is linked to the organization dimension, which in turn links to the currency dimension. That sounds like a snowflake schema to me.
Okay, let's see. The Loader service master node definitely needs to communicate with external data sources, that's a given. And the Yarn job nodes might also need to access external data, depending on the job requirements. I'm leaning towards option C as the best answer.
Ah, I've got it! The certification audit is primarily based on the actual processes and documentation, not just the personnel records or financial reports. I'll go with B.
