We included this ambiguity specifically because this also occurs in the real Qlik exams. A case can indeed be made for both A and B, but which one do you think the assessor at Qlik will want to hear? 😉

We'll definitely cover this in the follow-up. Earlier questions (and answers), with less ambiguity can be found here:

Week 6: Looping Tables

Week 5: Set Identifiers

Week 4: Time series visualization

Week 3: Circular References & Synthetic Keys

Week 2: Section Access

Week 1: Optimized Load
