Exam AZ-204 topic 2 question 35 discussion

Box 1: Custom handler Custom handlers can be used to create functions in any language or runtime by running an HTTP server process, for example Go or Rust. Box 2: extension bundles is needed to support the bindings and triggers that you use https://docs.microsoft.com/en-us/azure/azure-functions/functions-custom-handlers?WT.mc_id=thomasmaurer-blog-thmaure#bindings-support

Answer is correct. Box 1: Custom handler Custom handlers can be used to create functions in any language or runtime by running an HTTP server process, for example Go or Rust. Box 2: Trigger Functions are invoked by a trigger and can have exactly one. In addition to invoking the function, certain triggers also serve as bindings. You may also define multiple bindings in addition to the trigger. Bindings provide a declarative way to connect data to your code. Reference: https://docs.microsoft.com/en-us/azure/azure-functions/create-first-function-vs-code-other https://docs.microsoft.com/en-us/dotnet/architecture/serverless/azure-functions

Box2: extension bundles - As per question it is looking to connect declaritively with blob storage account, to connect declaritively one need to use bindings - as per below article https://learn.microsoft.com/en-us/azure/azure-functions/functions-triggers-bindings?tabs=isolated-process%2Cpython-v2&pivots=programming-language-csharp therefore trigger can't be the answer.

Custom Handler. Extension Bundle. To "declaratively connect" to an Azure Blob Storage account refers to the ability to specify in the function's configuration how and to what resources the function connects, without needing imperative programming to establish the connection. While a trigger can start a function based on activity in a Blob Storage (like creating or adding a new blob), it's the bindings that are more directly involved in the declarative connection to data sources or sinks.

Box 1: Custom handler Box 2: trigger extension bundles allow you to use trigger in the custom handler but it can't do the job alone you have to use trigger to fire the function Custom handlers are best suited for situations where you want to: -Implement a function app in a language that's not currently offered out-of-the box, such as Go or Rust. -Implement a function app in a runtime that's not currently featured by default, such as Deno. With custom handlers, you can use triggers and input and output bindings via extension bundles. https://learn.microsoft.com/en-us/azure/azure-functions/functions-custom-handlers

Question in my exam on 22sept 2023

Got this on 2023sept

For the second I vote for 'Trigger': https://learn.microsoft.com/en-us/azure/azure-functions/functions-triggers-bindings?tabs=isolated-process%2Cpython-v2&pivots=programming-language-csharp#add-bindings-to-a-function

I got this question on 6th August 2023. chose highly voted. passed with 904. I got Case study: city. All questions are from ExamTopics.

Can anyone mentioned what the answer is for box2, there are 2 answers that got most voted which one is the correct one.

Got this on 6/28/2023 and passed with 850. Went with highly voted answer.

For Box 2: Trigger. (But Binding would make more sense if there is.) Extension bundles allow non-.NET functions apps to use the same bindings without having to deal with the .NET infrastructure. -> so it's not for general trigger or bindings setting. Reference: Register Azure Functions binding extensions https://learn.microsoft.com/en-us/azure/azure-functions/functions-bindings-register

Got this 2023-05-12. FYI: case: You need to configure authorization. case: You need to ensure the app does not time out and processes the blob data case study: VanArsdel Inc Canada

Box 1: Custom handler Box 2: extension bundles CHATGPT

Got this on exam 12/30/2022

Box 2: extension bundles or Triggers? which one is correct ? both answers are highly voted with valid comments

Custom Handler , Extension Bundle instead of native triggers.
