• Retrieve the Exif data from the image while minimizing bandwidth and processing time.
• Utilizes the REST API.

Retrieve via HEAD because "For example, if your application needs the Exif (exchangeable image format) data from a photo, it can retrieve the photo and extract it. To save bandwidth and improve performance, your application can store the Exif data in the blob's metadata when the application uploads the photo. You can then retrieve the Exif data in metadata using only a HEAD request." Ref: https://learn.microsoft.com/en-us/azure/storage/blobs/storage-performance-checklist#use-metadata

we want to store as Metadata : so PUT for set and GET/HEAD to retrieve. https://learn.microsoft.com/en-us/training/modules/work-azure-blob-storage/6-set-retrieve-properties-metadata-rest?ns-enrollment-type=learningpath&ns-enrollment-id=learn.wwl.develop-solutions-that-use-blob-storage

I see where you come from on the link, however generally POST is for new data and PUT is for overriding existing data. When the question is phrased "Store the Exif (exchangeable image file format) data from the image as blob metadata when the application uploads the image." I lean towards using POST and not PUT

POST on the first box might made the most sense for most people but the right answer is PUT And HEAD for the second one to get the metadata

why PUT? While you might think POST sounds more logical, using PUT instead of POST is generally preferred for storing or updating data in Azure Blob Storage, and here's why: PUT: The PUT method is idempotent, meaning that making the same PUT request multiple times will result in the same outcome. This is ideal for uploading a file or setting metadata because it ensures consistency—if you PUT the same data again, it will simply overwrite the previous version. as for retrieval i would also say GET

To store Exif data, you should use the PUT verb. To retrieve Exif data, you should use the HEAD verb. Explanation: PUT is used to upload the blob to Azure Storage and set the blob's metadata at the same time. The metadata is sent in the headers of the PUT request. HEAD is used to retrieve the metadata of a blob without downloading the blob itself. This minimizes bandwidth and processing time as only the headers of the response (which contain the metadata) are sent.

According to ChatGPT, first answer is correct: "When storing Exif data from an image as blob metadata in Azure Blob Storage, you can use the HTTP `PUT` method. This method is commonly used for uploading a resource to the specified URI, which in this case would be the URL of your Azure Blob Storage container. When making the `PUT` request, you can include the Exif data as metadata headers in the request to associate the metadata with the uploaded blob."
