Full question →easymultiple choiceObjective-mapped
You are developing a solution that needs to perform a multi-step workflow. The workflow involves calling several third-party APIs, and some steps may require waiting for a human approval via email. The workflow may run for hours. You want to use Azure Functions to implement this orchestration. Which Azure Functions feature should you use?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Durable Functions
Durable Functions is designed for stateful orchestrations, supporting long-running workflows, waiting for external events, and managing multi-step processes.
B
Distractor review
Timer trigger functions
Timer triggers run on a schedule and do not support event-driven multi-step orchestrations with human interaction.
C
Distractor review
Service Bus queue trigger functions
Queue triggers process single messages; they are not suitable for complex, stateful workflows that require waiting for external events.
D
Distractor review
Blob storage trigger functions
Blob triggers respond to blob creation/modification events and cannot orchestrate multi-step workflows with waiting.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

Question 5
You are developing an Azure Function that processes messages from an Azure Service Bus queue. The function uses a Service Bus queue trigger and runs on a Consumption Plan. The queue receives a high volume of messages in bursts. You need to ensure that the function scales out to handle the load but does not exceed 10 concurrent instances. Which configuration should you apply?

FAQ
Questions learners often ask
What does this AZ-204 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Durable Functions — Durable Functions provides stateful orchestration that can handle long-running processes, wait for external events (like human approval), and manage complex error handling. Timer triggers are for scheduled tasks, queue triggers are for single message processing, and blob triggers are for storage events—none support multi-step orchestration with waiting.
