You plan to implement an Azure Functions app.

The Azure Functions app has the following requirements:

• Must be triggered by a message placed in an Azure Storage queue.
• Must use the queue name set by an app setting named input_queue.
• Must create an Azure Blob Storage named the same as the content of the message.

You need to identify how to reference the queue and blob name in the function.json file of the Azure Functions app.

How should you reference the names? To answer, select the appropriate values in the answer area.

NOTE: Each correct selection is worth one point.

Queue name c. %input_queue%: In Azure Functions, you can use the %name% syntax in the function.json file to reference app settings. So, to reference the queue name set by an app setting named input_queue, you would use %input_queue%. Blob name a. {queueTrigger}: The {queueTrigger} binding expression gets the content of the queue message that triggered the function. This can be used to create a blob with the same name as the content of the message.
