Question 1hardmultiple choice
Full question →hardmultiple choiceObjective-mapped
You have implemented a long-running order processing workflow using Azure Durable Functions. The orchestration may run for hours and involves multiple activity functions. You need to monitor the status of all running orchestrations and receive alerts when an orchestration fails. Which approach provides the most comprehensive and real-time monitoring?
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
Distractor review
Use the Durable Functions HTTP API to poll the status of each orchestration.
The HTTP API allows querying status of individual orchestrations by instance ID, but it does not provide a consolidated view of all running orchestrations or failure alerts.
B
Distractor review
Use Azure Monitor to create alerts on custom metrics published by the Durable Functions.
While you can publish custom metrics, Azure Monitor metrics are aggregated and do not provide the detailed orchestration-level telemetry needed for pinpointing failures.
C
Best answer
Enable Application Insights for the Functions app and use its telemetry to monitor orchestration execution and set alerts.
Application Insights automatically captures orchestration lifecycle events (start, running, failed, etc.). You can use Kusto queries to monitor running orchestrations and create alerts on failed orchestrations with detailed context.
D
Distractor review
Use Azure Logic Apps to periodically check the orchestration status and send alerts.
Logic Apps are workflow orchestrators themselves, not a monitoring tool. Polling via Logic Apps would be inefficient and would not provide real-time or detailed telemetry.
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.

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: Enable Application Insights for the Functions app and use its telemetry to monitor orchestration execution and set alerts. — Application Insights provides deep integration with Durable Functions, emitting telemetry for orchestration and activity function lifecycle events. You can query this telemetry in real-time, set up alerts on failures, and visualize execution history. The Durable Functions HTTP API (A) can check individual orchestration status but is not suitable for monitoring all or running orchestrations. Azure Monitor metrics (B) provide aggregate counts but no detailed failure alerts per orchestration. Azure Logic Apps (D) is not designed to monitor Durable Functions orchestrations.
