- A
Create a metric alert on the Http5xxErrors metric with a 5-percent threshold, a 5-minute evaluation window, and an action group that sends email
App Service emits Http5xxErrors as a platform metric. A metric alert configured with a 5-percent threshold and a PT5M evaluation window checks the condition every minute and fires after the threshold is breached continuously for 5 minutes. The action group routes the alert to the team's email.
- B
Create a log alert that queries the App Service diagnostic log table every 5 minutes and emails the team if the 5xx count exceeds a threshold
Why wrong: Log alerts work, but they require diagnostic settings to route logs to a Log Analytics workspace, and query latency adds delay beyond the 5-minute evaluation window. For platform metrics already exposed natively, metric alerts are simpler, faster, and require no log forwarding setup.
- C
Enable Application Insights availability tests and configure an alert on test failure rate
Why wrong: Availability tests check whether an endpoint responds to HTTP pings from external locations. They detect downtime or reachability issues but do not reflect the HTTP 5xx error rate of real user traffic.
- D
Configure a diagnostic setting to stream logs to Azure Storage, then write a Function that reads the storage file and sends email when errors are found
Why wrong: This is an over-engineered custom pipeline. Azure Monitor's built-in metric alert and action group system eliminates the need for custom code, storage routing, and a Function just to send an alert email.
Quick Answer
The correct answer is to create a metric alert on the Http5xxErrors metric with a 5-percent threshold, a 5-minute evaluation window, and an action group that sends email. This works because Azure Monitor metric alerts natively evaluate platform metrics like Http5xxErrors over a specified time aggregation, such as the average error rate across five minutes, and trigger an action group when the threshold is breached—all without any custom code. On the AZ-204 exam, this scenario tests your understanding of the metric alert pipeline versus log alerts or custom solutions, and a common trap is confusing the evaluation frequency (every minute) with the total window length (five minutes) needed to detect sustained violations. Remember the key distinction: metric alerts use static thresholds on pre-collected metrics, while log alerts require queries. For a quick memory tip, think “5-5-5”: 5xx errors, 5 percent threshold, 5-minute window.
AZ-204 Practice Question: Azure Monitor metric alert for 5xx error rate…
This AZ-204 practice question tests your understanding of monitor, troubleshoot, and optimize azure solutions. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. A key principle to apply: azure Monitor metric alert. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
The team needs to receive an email when an App Service's HTTP 5xx error rate exceeds 5 percent for more than five consecutive minutes. No custom code should be written. What combination of Azure Monitor features implements this requirement?

Correct answer & explanation
Create a metric alert on the Http5xxErrors metric with a 5-percent threshold, a 5-minute evaluation window, and an action group that sends email
Option A is correct because Azure Monitor metric alerts can directly evaluate the Http5xxErrors metric over a specified time window (e.g., 5 minutes) and trigger an action group when the threshold (5%) is breached. This requires no custom code and uses the native metric alert pipeline, which polls the metric every minute and aggregates over the evaluation window to detect sustained violations.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse metric alerts (which work on platform metrics like Http5xxErrors) with log alerts (which require querying diagnostic logs), or mistakenly think Application Insights availability tests are the correct tool for server-side error monitoring.
Detailed technical explanation
How to think about this question
Metric alerts in Azure Monitor use a sliding window aggregation (e.g., 'Total' or 'Average' over 5 minutes) and evaluate the condition every minute using a 'frequency' setting. The Http5xxErrors metric is emitted by the App Service platform at 1-minute granularity, and the alert fires only when the threshold is breached for the entire evaluation window (e.g., 5 consecutive minutes), preventing false positives from transient spikes. Action groups support multiple notification channels (email, SMS, webhook) and can be reused across alerts.

Key takeaway
Azure Monitor metric alert
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
