You have enabled Application Insights on your Azure Web App. You notice that some server-side exceptions are not appearing in the Application Insights portal. What is the most likely reason?
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
The Application Insights SDK is not installed in the application
If the SDK were not installed, no telemetry (including requests, dependencies) would be sent, not just exceptions.
B
Distractor review
The developer forgot to set the Instrumentation Key in the application configuration
Missing instrumentation key would prevent all telemetry from being sent, not only exceptions.
C
Distractor review
The web app is running on a Free tier App Service plan
The App Service plan tier does not affect the capturing of exceptions by Application Insights.
D
Best answer
The exceptions are being caught and handled in code without being re-thrown or explicitly logged
Caught exceptions that are not re-thrown or logged via TrackException are not automatically tracked. Developers must explicitly log handled exceptions to see them in Application Insights.
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: The exceptions are being caught and handled in code without being re-thrown or explicitly logged — Application Insights automatically tracks unhandled exceptions. However, exceptions that are caught by a try-catch block and not re-thrown (or explicitly tracked) will not be sent to Application Insights. If the instrumentation key or SDK was missing, no data would be sent at all. The hosting plan does not affect exception tracking. The SDK captures exceptions regardless of the plan.
