Practice question from Azure Functions (AZ-204: Developing Solutions for Microsoft Azure Develop Azure Compute Solutions), with the correct answer and a step-by-step solution.
easy · MCQ · Q-B0AF35
A company wants an Azure Function to run whenever a file is uploaded to the incoming container in Azure Blob Storage. The function must create a thumbnail and write it to the thumbnails container without explicitly creating BlobServiceClient code. Which design satisfies these requirements?
- A.Use a Blob trigger for the incoming container and a Blob output binding for the thumbnails container.Correct answer
- B.Use an HTTP trigger and require the uploading client to invoke the function after the upload.
- C.Use a timer trigger and periodically scan the incoming container with an HTTP output binding.
- D.Use a queue trigger and configure the thumbnails container as the function's application setting.
Solution
A Blob trigger starts the function when a blob is created or updated. A Blob output binding lets the function write the generated thumbnail to Blob Storage without directly managing the storage client for that operation.
