easy · MCQ · Q-8F69C3
An ASP.NET Core application uploads a JPEG to Azure Blob Storage. The application must ensure that browsers and download clients recognize the blob as an image. Which configuration should be used during upload?
- A.new BlobUploadOptions { HttpHeaders = new BlobHttpHeaders { ContentType = "image/jpeg" } }Correct answer
- B.new BlobUploadOptions { Metadata = new Dictionary<string, string> { ["ContentType"] = "image/jpeg" } }
- C.new BlobUploadOptions { Tags = new Dictionary<string, string> { ["ContentType"] = "image/jpeg" } }
- D.new BlobUploadOptions { Conditions = new BlobRequestConditions { IfNoneMatch = ETag.All } }
Solution
The ContentType value is an HTTP property, so it belongs in BlobHttpHeaders. Metadata and blob index tags are custom key-value collections and do not set the blob's HTTP content type.
