Quick Answer
The answer is Azure Monitor Alerts, because it is the dedicated Azure service for creating metric-based alert rules that continuously track Azure SQL Database performance and trigger notifications when CPU usage exceeds a defined threshold like 80%. Azure Monitor Alerts works by evaluating the “CPU percentage” metric at regular intervals, and when the condition is met, it can send alerts via email, SMS, or webhook, making it the precise tool for both monitoring and alerting. On the DP-300 exam, this question tests your ability to distinguish between Azure Monitor (which collects metrics) and Azure Monitor Alerts (which acts on those metrics with notification rules). A common trap is confusing Azure Monitor itself with its alerting subsystem—remember that monitoring alone does not alert. For a quick memory tip, think “Monitor sees, Alerts screams”—the metric is watched by Azure Monitor, but only Azure Monitor Alerts can notify you when CPU hits 80%.
This DP-300 practice question tests your understanding of monitor, configure, and optimize database resources. 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. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. 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.
You need to monitor Azure SQL Database performance over time and receive alerts when CPU usage exceeds 80%. Which Azure service should you use?
Automatic tuning
Why wrong: Automatic tuning adjusts performance, not monitoring.
Query Performance Insight
Why wrong: Query Performance Insight analyzes query performance.
Azure Monitor Alerts
Azure Monitor Alerts can trigger on CPU metric thresholds.
SQL Assessment
Why wrong: SQL Assessment checks best practices, not real-time alerts.

Correct answer & explanation
Azure Monitor Alerts
Azure Monitor Alerts is the correct service because it allows you to create metric-based alert rules that trigger when the CPU percentage of an Azure SQL Database exceeds a defined threshold (e.g., 80%). It continuously monitors performance metrics over time and sends notifications (e.g., email, SMS, or webhook) when the condition is met, fulfilling the requirement for both monitoring and alerting.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Automatic tuning
Why it's wrong here
Automatic tuning adjusts performance, not monitoring.
Query Performance Insight
Why it's wrong here
Query Performance Insight analyzes query performance.
Azure Monitor Alerts
Why this is correct
Azure Monitor Alerts can trigger on CPU metric thresholds.

SQL Assessment
Why it's wrong here
SQL Assessment checks best practices, not real-time alerts.
Common exam traps
The trap here is that candidates often confuse Query Performance Insight (which shows historical query performance data) with a monitoring/alerting tool, but it lacks the ability to set proactive threshold-based alerts like Azure Monitor Alerts provides.
Detailed technical explanation
Azure Monitor Alerts for Azure SQL Database uses the 'dtu_consumption_percent' or 'cpu_percent' metric (depending on DTU or vCore purchasing model) collected every minute from the database's telemetry. The alert rule evaluates the metric over a specified aggregation window (e.g., 5 minutes) and can trigger actions like sending an email to the Azure Resource Manager role or invoking a webhook for automated remediation. In a real-world scenario, you might combine this with an action group that triggers an Azure Function to scale up the database tier automatically.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
