A is solid, but I’m surprised people are still considering gsutil for this!

Wait, can Pub/Sub really handle that much data in real-time?

gsutil for both? Seems a bit outdated for real-time updates.

I disagree, B seems more efficient with BigQuery.

I vaguely remember that BigQuery Data Transfer Service could be useful for migrations, but I’m not sure how it fits with the real-time aspect.

I feel like gsutil is more for simple file transfers, and I don't think it handles real-time updates well, but I'm not completely confident about that.

I remember we discussed using Storage Transfer Service for large file migrations in class, but I'm not entirely sure if it's the best option here.

I think we practiced a similar question where Pub/Sub was mentioned for real-time updates, but I can't recall if it was paired with Dataflow or something else.

Okay, I've got this. RDDs are partitioned, fault-tolerant, and efficient for large-scale data processing. I'm pretty sure those are the key characteristics, so I'll select those options.

Hmm, I'm not sure. Orchestrator might be a good option too, since it can automate the deployment process and integrate with various cloud providers.

Okay, let me think this through. I know "faithful representation" means the information accurately reflects the real-world economic phenomena. So I just need to determine which of these is not part of that.
