I think B is a waste of time, just work within the limits!

C is a solid option, splitting files can help manage the load.

Wait, can you really increase the UPDATE limit? Sounds odd!

I don't think we can increase the DML limits in the console, right? That seems like it wouldn't be the best approach for this situation.

I vaguely recall a practice question where we had to merge records, so option D sounds familiar. It might be a more efficient way to handle the updates.

I think splitting the CSV into smaller files could help with the quotaExceeded error, but I wonder if that would complicate the update process.

I remember something about the limits on UPDATE statements in BigQuery, so reducing the number of records might be a good idea, but I'm not sure how much to reduce it by.

This seems like a straightforward user story question. I'd focus on the key details - the request is for visibility into sales reps' pipeline and revenue. The missing component is likely the "who" since that's not explicitly stated.

I think they're maybe combined at runtime? I recall a practice question that had similar wording.

Okay, let me think this through. I guess it depends on the scale of the change, but my initial instinct is to go with option D and request change control board involvement.

I thought fragments were only for UI components. I'm hesitant about this one but leaning towards “True” based on what I practiced.

Hmm, I'm not sure I remember the exact statistic from Xplor '06. I'll have to think this through and try to eliminate any options that don't seem plausible.
