Exam PL-300 topic 2 question 90 discussion

IF is correct answer https://learn.microsoft.com/en-us/dax/if-function-dax check last example

I would also answer IF

The IF.EAGER,HIGH, MEDIUM are the correct answer: In Power BI's DAX language, the primary difference between the "IF" and "IF.EAGER" functions lies in their evaluation strategy: "IF" only evaluates the expression corresponding to the true or false condition based on the logical test, while "IF.EAGER" always evaluates both expressions regardless of the condition, which can sometimes lead to performance improvements in specific scenarios where both branches need to be calculated regardless of the outcome. See this link:https://learn.microsoft.com/en-us/dax/if-eager-function-dax

I would vote for the IF not IF.EAGER as I cannot see the point to use second one. Then HIGH & MEDIUM

I will use IF instead of IF.EAGER due to values that are used in true/false arguments. If there would be more complex values (another formulas, references to columns etc.) I will prefer IF.EAGER. See https://learn.microsoft.com/en-us/dax/if-eager-function-dax -cdot above Examples part.

interestingly this article - https://dax.guide/if-eager/ - indicates that if and if.eager do pretty much the same thing but if.eager optimises better. So I can't say the answer is incorrect but which one are they looking for can't say.

The correct answer is IF, HIGH and MEDIUM

IF is also fine
