Question

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 files to end users. You need to recommend a solution for delivering the files to the users. The solution must meet the following requirements: - Ensure that the users receive files from the same region as the web app that they access. - Ensure that the files only need to be updated once. - Minimize costs. What should you include in the recommendation?

Options

  • AAzure File Sync
  • BDistributed File System (DFS)
  • Cread-access geo-redundant storage (RA-GRS)
  • Dgeo-redundant storage (GRS)

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.

AAzure File Sync

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.

BDistributed File System (DFS)
Cread-access geo-redundant storage (RA-GRS)Correct

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.
