This is exactly what happened to me last Friday when I took the exam and passed. The VM question is very confusing, The scenario and instruction window is taking most of the screen, with the actual VM window being like 1/4 of total exam window area, which has 4:3 ratio, with no obvious instructions on how to maximize it, so there is this "Next" button that I pressed intuitively, hoping that it will close the instructions and take me to the VM, but, instead, it just moved to the next question. There should be a warning message like "Are you sure you want to skip this VM Lab question and move to the next?" Also CompTIA/Pearson should look up the stats on how often this VM question is skipped due to mistakes like this.
P.S. It took the exam at the Testing Center
P.P.S. Congrats on Passing the Exam!
