AZ-305 · Question #186
You deploy two instances of an Azure web app. One instance is in the East US Azure region and the other instance is in the West US Azure region. The web app uses Azure Blob storage to deliver large fi
The correct answer is C. read-access geo-redundant storage (RA-GRS). To deliver large files from Azure Blob storage to users accessing regional web apps, ensuring files are served from the local region with a single update point and minimized costs, read-access geo-redundant storage (RA-GRS) is the recommended solution.

Why each option
To deliver large files from Azure Blob storage to users accessing regional web apps, ensuring files are served from the local region with a single update point and minimized costs, read-access geo-redundant storage (RA-GRS) is the recommended solution.
Azure File Sync synchronizes on-premises file shares with Azure Files and is not designed for delivering large Blob storage files from regional endpoints in this web app scenario.
RA-GRS replicates data to a secondary Azure region while providing read access to data in both the primary and secondary regions. This allows web apps in both East US and West US to read files from their geographically closest endpoint, ensuring users receive files from the same region as the web app they access, with the data only requiring a single update in the primary region.
