Wait, why would it fail? Sounds odd.

The trigger updates Is_Customer__c for each order.

I think the answer could be 100 because of the batch size limits in Salesforce, but I'm not entirely confident about that.

I feel like the code might fail if it tries to update more than 100 records at once, but I can't recall the exact limit.

I think if the trigger tries to update too many records at once, it might hit a limit. I practiced a similar question about bulk updates.

I remember something about governor limits in Apex, but I'm not sure how they apply here with the number of Orders.

I'm feeling pretty confident about this one. I've covered browser-side scripting in depth, so I think I can eliminate the incorrect options and select the right answer.

Okay, I've got this. IT governance is all about aligning IT strategy with business objectives, so the identification of business risk (option B) has to be the most critical element. That's the foundation for everything else.

I’m not totally sure, but could it be payable checks? I feel like that term came up in our sessions.
