The correct answer is to run the Azure CLI command `az sql server update --name sql-sales --resource-group rg-sales --enable-defender-for-sql true`. This is correct because Microsoft Defender for SQL, including vulnerability assessments, is a server-level configuration in Azure SQL Database; enabling it on the server automatically applies the protection to all databases on that server, such as SalesDB, regardless of any database-level security alert policy settings. On the Microsoft Azure Database Administrator Associate DP-300 exam, this question tests your understanding of the scope difference between server-level and database-level security features—a common trap is trying to enable Defender for SQL per database when it must be enabled at the server scope. Remember the key distinction: server-level settings like Defender for SQL cascade down, while database-level policies are independent. A useful memory tip is "server first, database second"—always check the server-level blade for Defender and vulnerability assessment enablement.
DP-300 Implement a secure environment Practice Question
This DP-300 practice question tests your understanding of implement a secure environment. 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.
Network Topology
You run the Azure CLI command shown in the exhibit for an Azure SQL Database named SalesDB. The output shows that the security alert policy is disabled. You need to enable Microsoft Defender for SQL, including vulnerability assessments, for this database. What should you do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Run 'az sql server update --name sql-sales --resource-group rg-sales --enable-defender-for-sql true'.
Option C is correct because enabling Microsoft Defender for SQL, including vulnerability assessments, is a server-level configuration in Azure SQL. The command 'az sql server update --enable-defender-for-sql true' activates Defender for SQL on the server, which automatically applies to all databases on that server, including SalesDB. The exhibit shows a database-level security alert policy is disabled, but the required feature is enabled at the server scope, not per-database.
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.
✗
Run 'az sql db update --name SalesDB --resource-group rg-sales --server sql-sales --enable-defender-for-sql true'.
Why it's wrong here
Defender for SQL is enabled at the server level, not database.
✗
Run 'az sql db threat-policy update --name SalesDB --resource-group rg-sales --server sql-sales --state Enabled'.
Why it's wrong here
This command does not exist in current Azure CLI.
✓
Run 'az sql server update --name sql-sales --resource-group rg-sales --enable-defender-for-sql true'.
Why this is correct
Enables Defender for SQL at the server level.

✗
Configure a server firewall rule to allow Azure services.
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse the database-level threat detection policy (legacy) with the server-level Microsoft Defender for SQL (modern), and mistakenly try to enable it per database using 'az sql db' commands instead of the correct server-level command.

Detailed technical explanation
How to think about this question
Microsoft Defender for SQL at the server level enables Advanced Data Security (ADS), which includes vulnerability assessments and threat detection, and is billed per server. The vulnerability assessment feature uses a built-in scanner that runs weekly and stores results in a storage account; it cannot be enabled per database independently. In a real-world scenario, if you enable Defender for SQL on the server, all existing and future databases inherit the protection, simplifying management.

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 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.
