- A
Application Insights metric alert on 'Server response time' with condition 'Greater than 2' and evaluation frequency 5 minutes
Metric alerts are designed for threshold-based monitoring; this configuration will fire if the 5-minute average exceeds 2 seconds.
- B
Log alert based on a Kusto query that measures average response time in 5-minute windows
Why wrong: Log alerts can work but are more complex to set up and incur higher latency and cost; metric alerts are simpler for standard metrics.
- C
Smart Detection alert on response time degradation
Why wrong: Smart Detection detects anomalies, not fixed thresholds; it may not fire for a consistent 2-second threshold.
- D
Availability test alert for HTTP response time
Why wrong: Availability tests monitor synthetic transactions, not real user requests; they are not designed for server response time from actual traffic.
Quick Answer
The correct choice is an Application Insights metric alert on 'Server response time' with condition 'Greater than 2' and an evaluation frequency of 5 minutes. This alert rule type is ideal because metric alerts continuously evaluate a rolling 5-minute window of the average server response time, triggering only when the threshold of 2 seconds is exceeded, which matches the requirement for near-real-time performance monitoring. On the Microsoft Azure Developer Associate AZ-204 exam, this tests your understanding of when to use metric alerts versus log alerts or activity log alerts—a common trap is selecting a log alert, which is better for complex queries on raw telemetry, not simple numeric thresholds. Remember the memory tip: "Metric for the metric, log for the query"—if you need a simple threshold on a performance counter like server response time, always reach for a metric alert.

Correct answer & explanation
Application Insights metric alert on 'Server response time' with condition 'Greater than 2' and evaluation frequency 5 minutes
A metric alert on 'Server response time' is the correct choice because it continuously evaluates the average server response time over a rolling 5-minute window and triggers when the value exceeds 2 seconds. Metric alerts are designed for near-real-time monitoring of performance counters like response time, with a fixed evaluation frequency that matches the aggregation window, making them ideal for this scenario.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Application Insights metric alert on 'Server response time' with condition 'Greater than 2' and evaluation frequency 5 minutes
Why this is correct
Metric alerts are designed for threshold-based monitoring; this configuration will fire if the 5-minute average exceeds 2 seconds.
Related concept

- ✗
Log alert based on a Kusto query that measures average response time in 5-minute windows
Why it's wrong here
Log alerts can work but are more complex to set up and incur higher latency and cost; metric alerts are simpler for standard metrics.
- ✗
Smart Detection alert on response time degradation
Why it's wrong here
Smart Detection detects anomalies, not fixed thresholds; it may not fire for a consistent 2-second threshold.
- ✗
Availability test alert for HTTP response time
Why it's wrong here
Availability tests monitor synthetic transactions, not real user requests; they are not designed for server response time from actual traffic.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing metric alerts (which evaluate pre-aggregated performance counters in near-real-time) with log alerts (which require querying raw telemetry data and have higher latency), leading candidates to incorrectly choose the log-based option for a simple threshold-based metric condition.
Detailed technical explanation
How to think about this question
Under the hood, Application Insights metric alerts use the same aggregation and time-series data as the Metrics Explorer, with a 1-minute granularity for the 'Server response time' metric. The rolling 5-minute window is implemented by evaluating the average of the last five 1-minute data points, and the alert fires when the condition is met at the evaluation frequency (every 5 minutes). A real-world scenario is monitoring a critical API endpoint where sustained response time degradation above 2 seconds indicates a performance bottleneck, requiring immediate action.
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.
TExam Day Tips
- 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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.

- B.A log alert with a custom KQL query
- ✓ C.A metric alert with 'Server response time' as the signal
- D.An activity log alert
Why C: Option A is correct because a metric alert on the 'Server response time' metric can trigger when the threshold is exceeded. Option B (log alert) requires log queries. Option C (activity log alert) is for resource events. Option D (availability alert) is for endpoint availability.
