The answer is to review the SQL database auditing logs to identify the source queries. This is the most effective immediate action because SQL database auditing captures a detailed record of all database events, including the exact SQL statements executed, which allows you to validate whether the suspicious activity is a genuine SQL injection attack or a false positive. On the Microsoft Azure Security Engineer Associate AZ-500 exam, this scenario tests your understanding of real-time validation versus other security controls; a common trap is confusing vulnerability assessments (which are periodic scans, not real-time) or firewall rules (which prevent access but don’t validate attacks). Remember, auditing logs are your forensic microscope—they show the actual injected queries, while options like TDE only encrypt data at rest and offer no attack validation. Memory tip: “Audit to validate, don’t guess—logs show the mess.”
AZ-500 Practice Question: Secure Azure using Microsoft Defender for Cloud and Microsoft Sentinel
This AZ-500 practice question tests your understanding of secure azure using microsoft defender for cloud and microsoft sentinel. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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.
Your organization uses Microsoft Defender for Cloud to monitor Azure SQL databases. You receive an alert indicating a potential SQL injection attack. What is the most effective immediate action to validate and respond?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Review the SQL database auditing logs to identify the source queries
Option C is correct because the SQL database auditing records show the actual queries, allowing validation. Option A is wrong because enabling TDE does not help validate an attack. Option B is wrong because vulnerability assessments are not real-time. Option D is wrong because firewall rules may block legitimate traffic.
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.
✗
Enable Transparent Data Encryption (TDE) on the database
Why it's wrong here
TDE is encryption at rest, not for attack validation.
✗
Run a vulnerability assessment on the database
Why it's wrong here
Vulnerability assessment is not real-time.
✓
Review the SQL database auditing logs to identify the source queries
Why this is correct
Auditing logs provide detailed query information.

✗
Immediately block all IP addresses from the alert in the SQL firewall
Why it's wrong here
Blocking all IPs may be too aggressive and cause false positives.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
