Definitely A, precision and datatype must align.

Wait, can the port names really be the same? That seems odd!

C is misleading, Union doesn't remove duplicates.

A is correct, ports need to match!

I vaguely recall that D could be true since the port names might not need to match, but I need to double-check that.

I feel like C is misleading because I thought the Union transformation just combined data without removing duplicates.

I remember practicing a question where the Union transformation allowed for different datatypes, so maybe B is correct?

I think option A sounds familiar, but I'm not entirely sure if the precision and datatype really have to match exactly.

This is a good question to test our knowledge of the Field Service mobile app features. I'm confident I can identify the three overview cards that are provided to technicians, so I'll carefully select the appropriate options.

I'm a little confused by this question. Are we supposed to just choose one of the options, or do we need to explain how we would use them? I want to make sure I understand the requirements before I start writing my answer.
