similar thing happened to me. it was one of the hottest days and i took a sip of water before pressing start exam.  I put the water out of my reach. Then clicked start.  I saw the first question for about a minute then exam suspended.  the moderator told me to remove the water from my area so i got up picked up my glass of water and put it well away.  Mod then said as I had been out of camera for a few seconds that exam is suspended!  Luckily the exam company saw sense and rescheduled my exam for later on.  But huge stress just before the Prof Data Engineer exam!!! Databricks please look into this.  There are so many over zealous mods on the exams!
