Question

Drag and Drop Question You have an on-premises app named App1. Customers use App1 to manage digital images. You plan to migrate App1 to Azure. You need to recommend a data storage solution for App1. The solution must meet the following image storage requirements: - Encrypt images at rest. - Allow files up to 50 MB. - Manage access to the images by using Azure Web Application Firewall (WAF) on Azure Front Door. The solution must meet the following customer account requirements: - Support automatic scale out of the storage. - Maintain the availability of App1 if a datacenter fails. - Support reading and writing data from multiple Azure regions. Which service should you include in the recommendation for each type of data? To answer, drag the appropriate services to the correct type of data. Each service may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content. NOTE: Each correct answer is worth one point. Answer:

Correct arrangement

  • Azure Blob storage
  • Azure Cosmos DB

Explanation

Azure Blob storage is the correct choice for image storage because it natively supports encryption at rest, allows files up to 50 MB (supports up to 190.7 TB per blob), and integrates with Azure Front Door and WAF for access management. Azure Cosmos DB is the correct choice for customer account data because it supports automatic scale-out, provides multi-region read/write capabilities (multi-master replication), and maintains availability through zone and regional redundancy, satisfying all three customer account requirements.
