AZ-104: Microsoft Azure Administrator
Microsoft provides two re-certification options for those who want to demonstrate continues competence in these areas. You can demonstrate that you're staying current in the technology by either taking a re-certification exam or stay-current course within two years of earning your certification. As soon as you pass either the course or the exam, the expiration date on your certification will be extended two years from that date. For more information, please check out the FAQ on Microsoft's Certification Exam Policies page.
