Hello everyone, I'm preparing for my CLED exam and I don't understand question 21 of the example exam. The exam states that D is the right answer, but I don't understand why. The RT FIFO Read function clearly has a timeout of 100ms wired to it. Why would the CPU speed go to 100%? Thank you

From the LabVIEW Help article Data Communication Methods in LabVIEW, an RT FIFO has a polling mode by default. Therefore, it will use as much CPU as possible looking for new data to come in instead of waiting for a notification that there is data. This is done to keep jitter at a minimum. The DMA FIFO behaves the same way.
