Availability Zones on all Regions when taking the Azure Test

Hi I will be sitting the AZ-900 exam tomorrow, and there a bit of information that seems to be inconsistent across different training and supports, including practice test.
For the purpose of the Exam, do we treat all Regions as having Availability Zones or not?
eg, Are availability zones available in all regions? Yes or No? Because I have taken practice exams which answer either of these.

Brian Eves

Question from the AZ-900 test exam. Which of the following statements about Azure availability zones are true? Each Azure region has a minimum of three availability zones. CORRECT (Each Azure region has a minimum of three availability zones) – To ensure resiliency, there’s a minimum of three separate zones in all enabled regions. Availability Zones.

However when reviewing the list of Regions with Availability zones only one of the 4 Australian regions is mentioned as an example.

Hi Brian. In short, not all regions have availability zones. But, for those regions that do, there are 3 availability zones within those regions. This is something you have to keep in mind when deploying your azure resources to ensure data redundancy.

Hi Brian,

Thanks for the feedback on the question. It has been updated now to accurately describe that if a region supports availability zones, then there are three.

I hope you did well on the exam. 😊
