I’m a bit lost on the transitive dependency concept; I hope I’m not mixing it up with functional dependency.

I practiced a similar question where we had to identify dependencies, and I feel like Cust_ID should be the determinant here.

I remember something about determinants, but I can't recall if Cust_Name qualifies as one in this case.

I think Cust_Name is functionally dependent on Cust_ID, but I'm not entirely sure if that's the right term to use.

I'm a bit confused by the options here. PCC, CMUI, ACCE - I'm not sure what any of those are. I'll have to review my notes to see if I can figure this out.

Ugh, I'm drawing a blank on the different ipmpstat modes. I know it's used for IPMP, but I can't remember the specifics. I'll have to guess on this one and hope for the best.
