Microsoft has decided to consolidate AZ-100 and AZ-101 into AZ-103. This consolidation is intended to simplify the Azure Administrator Associate certification that can be achieved through sitting for one exam.
The unfortunate thing is that this new exam is only available after May 1, 2019.
Those that are currently studying to pass the original exams have asked whether or not they should wait.
The recommendation is that if a person has already passed either AZ-100 or AZ-101 and ready to sit for the other exam, they should finish the track. Otherwise, if the person is just starting out to obtain the certification, they can begin studying, but focus on AZ-103.
The AZ-103 Microsoft Azure Administrator certification exam is geared towards Azure Administrator candidates who manage cloud services that span compute, networking, storage, security, and other cloud capabilities within Microsoft Azure. These candidates should have a deep understanding of each service across the full IT lifecycle; including infrastructure services, applications, and environments. They will also be able to make recommendations on services to us for optimal performance and scale, including provision, size, monitor, and adjust Azure resources.
