AZ-104 Practice Question 100: Metric Alert Dynamic Thresholds
Microsoft Azure Administrator Associate (AZ-104) · Test 10 · question 10 of 10
A metric alert on the request count of a web app uses a static threshold. Traffic follows daily and weekly patterns, so the alert fires falsely at peak hours and misses drops at night. The administrator wants to stop tuning thresholds by hand.
What should the administrator do?
Show answer and explanation
Answer:
Dynamic thresholds use machine learning on the history of the metric to learn its patterns, including hourly, daily and weekly seasonality, and set the thresholds automatically. The alert fires only on an anomaly, so the thresholds need no manual tuning.
Option A multiplies rules and still needs manual tuning as the pattern changes.
Option B keeps a fixed value, so the same problem remains.
Option D reports control-plane events such as resource operations and does not evaluate a metric.
