AZ-900: Ultimate Azure Fundamentals Certification Prep Tests

About this course

Free Sample Question 1 out of 3:Your company is migrating a critical application to Azure. The application's data must be highly available and resilient to regional disasters. A key requirement is that in the event of a primary region outage, the data should still be accessible for read operations from a secondary geographic location. Which Azure Storage redundancy option should you choose to meet these requirements?A. Locally redundant storage (LRS)B. Zone-redundant storage (ZRS)C. Geo-redundant storage (GRS)D. Read-access geo-redundant storage (RA-GRS)Correct Answer: DExplanation:Locally redundant storage (LRS) is incorrect because it only provides durability within a single datacenter in the primary region and does not protect against regional outages or offer a secondary readable location.Zone-redundant storage (ZRS) is incorrect because it provides durability by replicating data across multiple availability zones within a single primary region, but not across different geographic regions, nor does it offer a secondary readable geographic location.Geo-redundant storage (GRS) is partially correct as it replicates data to a secondary paired region, providing protection against regional outages. However, by default, it does not allow read access to the data in the secondary region.Read-access geo-redundant storage (RA-GRS) is the correct option. It replicates your data to a secondary paired region (like GRS) for protection against regional disasters and, crucially, provides read access to the data in the secondary location, satisfying the requirement to access data for read operations during a primary region outage.Free Sample Question 2 out of 3:Your company is planning to deploy a complex, mission-critical application on Azure.
