I’m surprised this is even a question, UDFs are straightforward!

Option B looks solid for a UDF.

I’m leaning towards Option B, but I can’t recall if we discussed any edge cases that might affect the logic here.

I feel like I might be mixing up the return types in these options. Wasn't there something about needing to specify the return type explicitly?

I think Option C looks familiar; it had a similar structure to the examples we went over in class.

I remember we practiced creating UDFs in our last session, but I'm not sure which syntax is correct for this specific case.

This question seems straightforward, but I want to make sure I understand the requirements correctly before answering.

Okay, let me see here. I think A and B are the two true statements, since custom dimensions and their members can vary across plan types. I'll double-check the other options, but those seem like the most likely answers.

The way I see it, the main difference is that managed indemnity plans use precertification and utilization review, while traditional indemnity plans do not. So I'm going to go with option A as my answer.
