The answer is Azure SQL Auditing, which you must enable to audit failed login attempts in Azure SQL Database. This feature captures all database events, including authentication failures, and writes them to an audit log in an Azure Storage account, Log Analytics workspace, or Event Hubs, recording the exact timestamp, source IP address, and error message like 'Login failed for user'. On the Microsoft Azure Database Administrator Associate DP-300 exam, this question tests your ability to distinguish between Azure SQL Auditing and other security features such as Advanced Threat Protection or vulnerability assessment—a common trap is confusing auditing with monitoring or alerting. Remember that auditing is about logging events for later review, not real-time alerts. A helpful memory tip: think of "A" for Auditing and "A" for Authentication failures—both start with the same letter, so when you need to track failed logins, enable Azure SQL Auditing.
DP-300 Implement a secure environment Practice Question
This DP-300 practice question tests your understanding of implement a secure environment. 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 audit all failed login attempts to an Azure SQL Database. Which feature should you enable?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure SQL Auditing
Azure SQL Auditing is the correct feature because it tracks database events, including failed login attempts, and writes them to an audit log in an Azure Storage account, Log Analytics workspace, or Event Hubs. This allows you to review and analyze authentication failures for security and compliance purposes. The audit logs capture the exact timestamp, source IP address, and the specific error message for each failed login, such as 'Login failed for user'.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Azure SQL Advanced Threat Protection
Why it's wrong here
ATP detects anomalous activities but does not provide detailed audit logs.
✗
Azure SQL Database Vulnerability Assessment
Why it's wrong here
Vulnerability Assessment identifies security vulnerabilities, not audit logs.
✓
Azure SQL Auditing
Why this is correct
Auditing can log failed login attempts to a storage account, Log Analytics, or Event Hubs.

✗
Dynamic Data Masking
Why it's wrong here
Data masking obfuscates sensitive data, not audit.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure SQL Auditing with Advanced Threat Protection, assuming that threat detection automatically logs all failed logins, but in reality, ATP only alerts on suspicious patterns and does not provide a comprehensive audit trail of every failed login attempt.
Detailed technical explanation
How to think about this question
Azure SQL Auditing works at the server or database level and uses extended events (XEvents) under the hood to capture login events, including failed logins (event class 14 – Audit Login Failed). The audit logs can be configured to include detailed information such as the client IP address, application name, and the exact T-SQL statement that triggered the failure. In a real-world scenario, enabling auditing with a retention policy of at least 90 days is often required for compliance frameworks like SOC 2 or PCI DSS, and you can query the audit logs using the sys.fn_get_audit_file function to filter for failed logins specifically.
KKey Concepts to Remember

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
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.
