Wait, what if the Subject is blank? Does that break it?

I think A is misleading, it's just one child per parent.

I wonder if the trigger would fail if the Subject field is blank, which makes me lean towards option D.

I practiced a similar question, and I believe that multiple child cases are created, so option A might be correct.

I'm not entirely sure, but I remember something about triggers causing infinite loops. Could option C be a possibility?

I think option B makes the most sense since the code creates one child case for each parent case in Trigger.new.

Ah, I remember learning about this in class. For vSAN, the boot device needs to be a 16GB SLC SATADOM. The high-performance CPUs and 1TB of memory are a good indication that this is the right answer.

I've got this one! ServletContext is the way to go for sharing data across the entire web application. I remember learning that in class.
