B. Azure portal
C. Azure PowerShell

I think the answer is correct. The question talks about function app. A function app can only be created via portal or CLI. What we create in Visual studio is an Azure function that needs to be deployed within a function app. Function app is more like a container that can host many functions.

That's misleading! Please try before you write. You can create function in both portal and in VS (and VSCode). If you change in portal, the code stored in storage account will not have version control (and lost if someone redeploys). If you want tracing only for temporal debugging, then you can do that in the portal. Otherwise best practice is to change in VS/VSCode with source control.

This is possible on the Azure portal only if the function App is running on Windows. In this case, we could use kudu to edit the host.json file. Otherwise, I think the most likely answer is to use Azure Functions core tool on Visual Studio Code

The Functions editor built into the Azure portal lets you update your code and your function.json file directly inline. This is recommended only for small changes or proofs of concept - best practice is to use a local development tool like VS Code. I would say portal.. as just host file changes.. correct me if i am wrong.

considering the requirement "You want to configure tracing for an Azure Function App project." A VS might be better answer.

I thought portal also and then read this in ms documentation: "The Functions editor built into the Azure portal lets you update your code and your function.json file directly inline. This is recommended only for small changes or proofs of concept - best practice is to use a local development tool like VS Code." https://docs.microsoft.com/en-us/azure/azure-functions/functions-reference#fileupdate. So which one is the correct answer?

so, answer is either Portal or Visual Studio Code, but the option in the question is Visual Studio, not Visual Studio Code, that's why Portal is the correct answer.

It is still project even if it is portal. you don't need to enable tracing locally. Just enable it in portal. Do your tracing and disable it.

You can use both but Portal is more convenient. The function editor built into the Azure portal lets you update the function.json file and the code filefor a function. The host.json file, which contains some runtime-specific configurations, is in the root folder of the function app.

Hei, We can change the config in both Visual Studio and Azure Portal. Why do we choose Azure Portal here? Tai
