I practiced a question like this, and I think assigning the poller to the node should come before saving it, which makes me think option A could be right.
I'm a bit confused on the order of the steps here. I'll need to review the material again to make sure I understand the proper sequence for creating a device studio poller.
Okay, let me walk through this step-by-step. I'm pretty confident the answer is B. You need to select the technology first, then assign the poller, specify the data source, and save it.
Hmm, I'm not entirely sure about this one. I'll have to think it through carefully. Maybe C or D could also be correct, but I'll need to double-check the steps.
I think the correct sequence is B. It makes the most sense to select the technology first, then assign the poller to a node, specify the data source, and finally save the poller.
