Wait, can we really handle historical data with just BigQuery?

Not so sure about that, what about latency issues?

I’m confused about the best combination here. I thought Cloud SQL was more for structured data, but it might fit in option D?

I think we practiced a question similar to this, and I remember Cloud Storage being mentioned for batch exports. That makes me lean towards option B as well.

I remember we discussed how Cloud Pub/Sub is great for real-time data streaming, so I think option B might be the right choice.

I'm not entirely sure, but I feel like Cloud Dataflow could be useful for processing the data streams. Maybe option A?

I'm feeling pretty confident about this one. The steps in option C look like the most direct way to troubleshoot the integration issue. Deleting and re-adding the instances should help reset the configuration and get things working again.

Hmm, I'm a bit unsure about the specifics of read/write splitting with this service. I'll need to review my notes to make sure I understand the correct answer.

Hmm, I'm a bit unsure about this one. The options seem to cover different potential issues with cloud services, but I'm not sure which one is the primary reason for Andrea's backup practices.

Hmm, I'm a bit unsure about this one. I know T1 connections are used for high-speed internet, but I can't remember the exact bandwidth. I'll have to think this through carefully.
