Exam AZ-204 topic 1 question 32 discussion

HTTP, Custom handler, true are the correct answers

This was on my exam in august 2023.

"enableForwardingHttpRequest": true Why? Since the C++ application (process.exe) is a native executable, it cannot directly handle HTTP requests. Azure Functions must forward HTTP requests to the custom handler (C++ app). Setting enableForwardingHttpRequest: true ensures that Azure Functions acts as a proxy, forwarding requests to process.exe for processing. When would enableForwardingHttpRequest: false be used? If the function does not depend on HTTP request details (e.g., input is processed from a queue or blob storage). If the function retrieves input from other bindings instead of HTTP. Since the question clearly states that the function receives images and returns processed images, HTTP request forwarding is required.

“enableForwardingHttpRequest” should be set to true to forward the HTTP request to your custom handler.

enableForwardingHttpRequest must be true: Ref: https://learn.microsoft.com/en-us/azure/azure-functions/create-first-function-vs-code-other?tabs=go%2Cwindows In the customHandler section, add a property named enableForwardingHttpRequest and set its value to true. For functions consisting of only an HTTP trigger, this setting simplifies programming by allow you to work with a typical HTTP request instead of the custom handler request payload.

If your C++ application Azure Function does not depend on information from the original HTTP request (like headers, query parameters, etc.), you might set enableForwardingHttpRequest to false to optimize performance and reduce unnecessary data transfer. If your C++ application Azure Function requires information from the original HTTP request, such as headers or query parameters, you might set enableForwardingHttpRequest to true so that the original request is forwarded to your function. So I would say True for this case!

Got this today. Went with answer here. Score 927

It should be "enableForwardingHttpRequest": true

On my exam 2023-10 before the Update of the Exam

On my exam 2023-07-13- went with "enableForwardingHttpRequest": true. Score 917

https://learn.microsoft.com/en-us/azure/azure-functions/functions-custom-handlers#, the last one should be true.

- Your Azure Function will be a custom handler since Azure Functions doesn't directly support C++ as a runtime. - enableForwardingHttpRequest is set to true to allow the custom handler to receive the HTTP request data

I will go with 'yes' In the function.json file, enableForwardingHttpRequest should be set to true for the Azure Function to accept HTTP requests and forward them to the C++ application for processing. This is because the C++ application is compiled as a native application and cannot directly receive HTTP requests. By setting enableForwardingHttpRequest to true, the Azure Function acts as a proxy and forwards incoming HTTP requests to the C++ application. So the correct option is: "enableForwardingHttpRequest": true

On my exam 2023-02-25

Everything looks gucci except enableforwardhttprequest got to be true. If it was false, our customer handler can receiving any incoming HTTP requests

enableForwardingHttpRequest should be true When enableForwardingHttpRequest is true, the behavior of HTTP-only functions differs from the default custom handlers behavior in these ways: The HTTP request does not contain the custom handlers request payload. Instead, the Functions host invokes the handler with a copy of the original HTTP request. The Functions host invokes the handler with the same path as the original request including any query string parameters. The Functions host returns a copy of the handler's HTTP response as the response to the original request. Source: https://learn.microsoft.com/en-us/azure/azure-functions/functions-custom-handlers

The third selection should be true ----'At the root of the app, the host.json file is configured to run handler.exe and enableForwardingHttpRequest is set to true'
