- A
Deploy an Azure Function with a Queue trigger on the Consumption plan.
Why wrong: An Azure Function on the Consumption plan runs independently and incurs separate costs and management, not sharing the same compute resources as the web app.
- B
Add an Azure WebJob to the App Service that hosts the main application.
WebJobs are deployed as part of the App Service and run in the same process or as background processes, sharing the same plan and scaling without extra services.
- C
Create a separate Azure Container Instance to run a continuous job.
Why wrong: ACI is a separate service with its own billing and management, adding overhead and not sharing the web app's compute resources.
- D
Use Azure Logic Apps with a recurrence trigger to poll the queue.
Why wrong: Logic Apps are a separate service for workflow automation; they incur additional costs and do not run within the web app's compute context.
Quick Answer
The answer is to add an Azure WebJob to the App Service that hosts the main application. This is correct because WebJobs run as background processes within the same App Service instance, sharing the same compute resources and scaling with the web app, which eliminates the need for separate deployment or monitoring overhead. For the AZ-204 exam, this scenario tests your understanding of background processing on App Service, specifically how WebJobs integrate with triggers like the QueueTrigger to read from Azure Storage Queues. A common trap is choosing Azure Functions, which, while similar, typically require a separate consumption or dedicated plan unless explicitly configured to run in an App Service plan, adding deployment complexity. Remember the key differentiator: if the requirement is to run on the same compute resources as the main web app with zero additional overhead, think WebJobs. Memory tip: "Same site, same plan, WebJob’s the man."
AZ-204 Develop Azure compute solutions Practice Question
This AZ-204 practice question tests your understanding of develop azure compute solutions. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
You are deploying a background processing job that reads messages from an Azure Storage Queue. The job must run on the same compute resources as the main web application and must not require additional deployment or monitoring overhead. Which solution should you use?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Add an Azure WebJob to the App Service that hosts the main application.
Option B is correct because Azure WebJobs run in the same App Service plan as the main web application, sharing compute resources without requiring separate deployment or monitoring. A WebJob with a continuous trigger can read from an Azure Storage Queue using the QueueTrigger attribute, meeting the requirement of no additional overhead.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
Deploy an Azure Function with a Queue trigger on the Consumption plan.
Why it's wrong here
An Azure Function on the Consumption plan runs independently and incurs separate costs and management, not sharing the same compute resources as the web app.
- ✓
Add an Azure WebJob to the App Service that hosts the main application.
Why this is correct
WebJobs are deployed as part of the App Service and run in the same process or as background processes, sharing the same plan and scaling without extra services.

Create a separate Azure Container Instance to run a continuous job.
Why it's wrong here
ACI is a separate service with its own billing and management, adding overhead and not sharing the web app's compute resources.
- ✗
Use Azure Logic Apps with a recurrence trigger to poll the queue.
Why it's wrong here
Logic Apps are a separate service for workflow automation; they incur additional costs and do not run within the web app's compute context.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose Azure Functions for queue processing without considering the requirement to share compute resources with the main web application, overlooking that WebJobs are the native background processing solution within App Service.
Detailed technical explanation
How to think about this question
Azure WebJobs run as background processes within the same App Service sandbox as the web application, using the same virtual machine and scaling settings. The continuous WebJob uses the Azure WebJobs SDK's QueueTrigger to poll the Storage Queue via HTTP REST calls, automatically handling lease management and poison messages. In a real-world scenario, this is ideal for lightweight background tasks like image processing or email sending that must share the web app's authentication and configuration.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.

Same concept, more angles
1 more ways this is tested on AZ-204
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. You are developing a background job that runs every hour on Azure App Service. The job must be resilient to restarts and should not affect the web app's performance. Which technology should you use?
easy- A.A background thread in the web application
- B.Azure Logic Apps
- ✓ C.WebJobs (triggered)
- D.Azure Functions (Consumption plan)
Why C: WebJobs (triggered) are designed specifically for running background tasks on Azure App Service. They run as separate processes from the web app, ensuring they do not affect the web app's performance, and they are resilient to restarts because the Azure WebJobs SDK automatically handles restart and retry logic. This makes them the ideal choice for a scheduled hourly job that must survive App Service restarts.
