You will take the exam online, on a computer. When you take the exam there will be a live proctor from our partner, Examity, observing. The proctor will help you begin your exam and will let you know if anything is out of order so you don’t accidentally violate exam rules.
Once you become MongoDB Certified your certification never expires. Please note however, that MongoDB Certifications align to a specific MongoDB major release and they will remain valid for that version.
