Exam AZ-204 topic 1 question 5 discussion

"You use the WebJobs SDK to design a triggered App Service background task" B - WebJob Usually you'll host the WebJobs SDK in Azure WebJobs, but you can also run your jobs in a Worker Role. The Azure WebJobs feature of Azure Web Apps provides an easy way for you to run programs such as services or background tasks in a Web App... https://github.com/Azure/azure-webjobs-sdk

the Correct Answer, D: Function

"WebJobs is a feature of Azure App Service that enables you to run a program or script in the same instance as a web app. All app service plans support WebJobs. There's no extra cost to use WebJobs." https://learn.microsoft.com/en-us/azure/app-service/webjobs-create?tabs=windowscode

Correct answer: B, https://learn.microsoft.com/en-us/azure/app-service/webjobs-create?tabs=windowscode (Run background tasks with WebJobs in Azure App Service) Azure Functions is a serverless solution that allows you to write less code, maintain less infrastructure, and save on costs. Instead of worrying about deploying and maintaining servers, the cloud infrastructure provides all the up-to-date resources needed to keep your applications running. According with https://learn.microsoft.com/en-us/azure/azure-functions/functions-overview?pivots=programming-language-csharp

B. WebJobs WebJobs is the most appropriate service for this scenario because: The question specifically mentions using the WebJobs SDK to design a triggered App Service background task. WebJobs is a feature of Azure App Service that enables you to run background tasks in the same instance as a web app. The WebJobs SDK is designed specifically for running background tasks in Azure App Service, and it provides support for triggered jobs that can be automatically invoked when new data is received in a queue. WebJobs can be configured to run continuously and respond to events, such as messages being added to a queue. The scenario describes a task that automatically invokes a function when new data is received in a queue, which aligns perfectly with the capabilities of WebJobs and the WebJobs SDK. While Azure Functions (option D) could also potentially be used for this scenario, the question explicitly mentions using the WebJobs SDK, making WebJobs the most appropriate choice for this specific use case.

Both WebJob and Function are acceptable, but the context mentions "use the WebJobs SDK to design". WebJobs SDK is a framework designed for WebJobs that simplifies writing code that responds to events in Azure services. I prefer B.WebJob

The scenario described suggests that you're using the WebJobs SDK to create a triggered background task that processes data from a queue. Therefore, the correct service to use for this purpose is: B. WebJobs WebJobs allow you to run scripts or programs as background processes alongside your web app in Azure App Service. They can be triggered by various sources, including queues, blobs, and timers. In this case, since you're triggering a function every time new data is received in a queue, WebJobs would be the appropriate service to configure and manage this process.

B - WebJobs is correct

HE ASK ABOUT A SERVICE NOT A FEATURE SO IT IS D

There an issue with the question. There is no mention of the OS where the app of the question is running. In the documentation microsoft specifies that: "WebJobs aren't supported for App Service on Linux yet" https://learn.microsoft.com/en-us/azure/app-service/webjobs-create For that reason i think that the answer D) Azure Functions should be a right answer too.

D. The question is ambiguously phrased, but clearly (to me) they ask for an Azure Service that will replace the WebJobs SDK on Web Apps. If nothing else WebJobs SDK is not a service and hence cannot be B.

Azure Functions is another Azure service that allows you to run code in the cloud without having to worry about infrastructure. It is designed to run small pieces of code called functions that can be triggered by various events such as changes to data in Azure Storage, a new message in a Service Bus queue, or a new file in an Azure Blob container. Although Azure Functions can be used to process queue data items, it is not specifically designed for this purpose. On the other hand, WebJobs is an Azure feature that allows you to run a program or script in the same context as a web app, API app, or mobile app. It is designed to run background tasks that can be invoked on a schedule, on demand, or continuously3. In your case, you are preparing to configure the service to process a queue data item. To achieve this goal, you should use WebJobs.

B- Webjobs The WebJobs SDK makes it easy to write, run, and monitor such background tasks in Azure. Azure function can do the same task but they are not part of the Azure app service and they're not considered as a background task.

The closest answer is B

Option B seems to be the correct answer. Webjob SDK can be used to automatically invoke a function every time new data is received in the queue.

Webjobs run under Azure webapps

My guts are saying B. Honestly it could either be WebJobs and Functions. The scenario mentions that the web app "WebApp1" is already being used and that the webjobs SDK is being used to design a triggered app service background task. Since WebJobs are designed to work specifically with Azure Web Apps, they provide a convenient way to run background tasks within the context of a web app
