Hello Kelebogile,
Thank you for contacting the Microsoft Community.
I understand that you encountered technical issues with your AZ-400 exam and received an incomplete score. I can only imagine the inconvenience you encounter, that prevented you from continuing and completing the exam. Allow me to provide information in order for you to proceed with your exam.
Please be advised if you encountered technical issues during your exam, the proctor would try to fix and restart your exam. In your case, that the incident repeats and your exam are completed. The items that you have answered will be recorded in you will receive a score. If the score you received didn't meet the passing grade, you will have to wait for 24 hours to schedule the exam again which will lead to a new exam fee.
However, since you encountered technical issues during your exam that leads to your exam to be tagged as complete. I recommend contacting Pearson VUE, since they have records of your exam, and you may report the incident. They can give you options and recommendations in order for you to proceed with your exam.

Additionally, you may want to check the Pearson VUE technical requirements in order to prevent the same issue from happening in your future exams. You may visit our About online exams with Pearson VUE for the technical requirements and you may also check your system for compatibility.
I hope this information helps and please let me know if further assistance is needed.
