You are monitoring an Azure web application with Application Insights. You notice a sudden increase in the number of failed requests. You want to be notified automatically when such anomalies occur, without manually setting static thresholds. Which Application Insights 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
Distractor review
Create a metric alert on the 'failed requests' metric with a static threshold.
A static threshold alert would require you to set a fixed number, which may not adapt to normal variations. Smart Detection is better for anomaly detection.
B
Best answer
Enable Smart Detection for failure anomalies.
Correct. Smart Detection automatically analyzes telemetry and alerts on anomalous patterns, such as a sudden spike in failed requests.
C
Distractor review
Use Log Analytics to run a query every 5 minutes and trigger an action.
Log Analytics queries can be used in log alerts, but they require you to define the query and threshold manually. Smart Detection is automated.
D
Distractor review
Create an availability test that periodically pings the application.
Availability tests monitor the endpoint's uptime and response, but they do not analyze anomalies in failed request patterns from real user traffic.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ
Questions learners often ask
What does this AZ-204 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Enable Smart Detection for failure anomalies. — Application Insights Smart Detection uses machine learning to automatically detect anomalies in application telemetry, such as unusual patterns in failed requests, response times, or dependency durations. It does not require manual threshold configuration. Alerts from Smart Detection are automatically generated and sent to the configured notification channels.
