Earlier during Microsoft Ignite 2019 conference, Microsoft Learning team has rolled out exams various role based certification exams for Administrators, Developers, Architects and DevOps engineers.

Initially there was a requirement for passing two exams: AZ-100 and AZ-101

  • AZ-100 – Microsoft Azure Infrastructure and Deployment
  • AZ-101 – Microsoft Azure Integration and Security
  • AZ-102 – (Upgrade Exam) – Microsoft Azure Administrator Certification Transition
