Exam AZ-900 topic 1 question 137 discussion

Correct is Functions, Logic Apps, Logic Apps -> https://docs.microsoft.com/en-us/learn/modules/azure-compute-fundamentals/azure-functions?ns-enrollment-type=LearningPath&ns-enrollment-id=learn.az-900-describe-core-azure-services

Executes Code - Azure Functions Is Stateful - Azure Logic Apps Runs only in cloud - Azure Logic Apps

Azure Function is always stateful. Logic Apps can be both.

This is the correct answer: Executes code = Azure Functions Is Always Stateful = neither Azure Functions nor Azure Logic Apps is always stateful. According to these links below, both services can be stateful and/or stateless: Azure Functions (https://learn.microsoft.com/en-us/azure/azure-functions/durable/durable-functions-overview?tabs=in-process%2Cnodejs-v3%2Cv1-model&pivots=csharp ; https://learn.microsoft.com/en-us/archive/msdn-magazine/2019/august/azure-affairs-of-state-serverless-and-stateless-code-execution-with-azure-functions) Azure Logic Apps (https://learn.microsoft.com/en-us/azure/logic-apps/logic-apps-overview) Runs only in cloud = Azure Logic Apps

none of the two options are always steteful, A single logic app can have multiple stateful and stateless workflows. Functions are also stateful or stateless

Second answer should be blanc. Nothing is holding you back from creating a stateless Azure Logic App. They even state it on the Logic App page: "Support stateless workflows to enhance performance for request and response scenarios." https://azure.microsoft.com/en-us/products/logic-apps So it's definitely not ALWAYS stateful. And of course same is true for Azure Functions

Executes: functions Always stateful: ALA* *Azure Functions has two programming models: V3 and V4. V3 functions are always stateless, while V4 functions can be either stateless or stateful by using the Durable Functions extension. Durable Functions lets you write orchestrator functions and entity functions that define stateful workflows and entities using the Azure Functions programming model. https://learn.microsoft.com/en-us/azure/azure-functions/durable/durable-functions-overview Runs ONLY in cloud: ALA** **Azure Functions can run locally, on any self-managed server, in containers or in Azure. Logic Apps run only in Azure. https://learn.microsoft.com/en-us/azure/azure-functions/functions-compare-logic-apps-ms-flow-webjobs

Functions can be either Stateful OR Stateless. The Answer to B is Logic Apps.

A single logic app can have multiple stateful and stateless workflows.

Azure Logic Apps is always stateful, while Azure Functions can be either stateless or stateful. So second fill is wrong

According to Chatgpt: Azure Logic App is always stateful, whereas Azure Function can be stateful or stateless, depending on how it is designed and implemented.

Correct answer is: Functions, Logic Apps, Logic Apps. Logic Apps are always stateful and they cannot execute code.

Functions: Execute code, can be either stateless or stateful, and Can run locally or in the cloud. Logic App: Execute logic, Stateful, Runs only in the cloud. https://learn.microsoft.com/en-us/training/modules/azure-compute-fundamentals/azure-functions

Functions can be either stateless or stateful. When they're stateless (the default), they behave as if they're restarted every time they respond to an event. When they're stateful (called Durable Functions), a context is passed through the function to track prior activity.
