AZ-204 Certification Practice Question #28

Question

You are developing a C++ application that compiles to a native application named process.exe. The application accepts images as input and returns images in one of the following image formats: GIF, PNG, or JPEG.
You must deploy the application as an Azure Function.
You need to configure the function and host json files.
How should you complete the json files? To answer, select the appropriate options in the answer area.

Accepted Answer

To execute a native C++ executable (`process.exe`) as an Azure Function, you must configure a Custom Handler. In `function.json`, the output binding for the HTTP response requires specifying `"type": "http"`. In `host.json`, the custom handler configuration block must begin with the `"customHandler": { "description": {` section to define the path to the executable (`process.exe`). Additionally, setting `"enableForwardingHttpRequest": true` ensures that the Functions host invokes the handler with a copy of the original HTTP request directly instead of a structured JSON payload, enabling the native binary to handle the request/response cycle directly.
