The correct answer is to set the minimal TLS version to 1.2, add a firewall rule for your office IP range while removing the default 'Allow Azure services' rule, and enable auditing with SCHEMA_OBJECT_CHANGE_GROUP. This configuration directly addresses the remaining requirements: enforcing TLS encryption for all application connections, preventing unauthorized internet access by restricting the firewall to only your office IP range, and capturing schema changes through targeted auditing. On the Microsoft Azure Database Administrator Associate DP-300 exam, this scenario tests your understanding of layered security—combining network controls, encryption enforcement, and audit policies—rather than relying on a single feature like TDE alone. A common trap is forgetting to remove the permissive 'Allow Azure services' rule, which would leave a backdoor from other Azure services. Remember the mnemonic "TFA" for TLS, Firewall, and Auditing to recall the three remaining steps after TDE is enabled.
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 are a junior DBA at a startup that uses Azure SQL Database for its SaaS application. The application uses a single database and the development team frequently makes schema changes. You need to implement security measures to:
1. Ensure that all connections from the application use TLS encryption.
2. Prevent unauthorized access from the internet.
3. Allow your office IP range (203.0.113.0/24) to connect for management.
4. Enable auditing of all schema changes.
5. Encrypt the database at rest using Azure-managed keys.
You have already enabled Transparent Data Encryption (TDE) with service-managed keys. What should you do next to meet the remaining requirements?
Set the minimal TLS version to 1.2. Enable auditing with SCHEMA_OBJECT_CHANGE_GROUP.
Why wrong: Missing firewall rule to restrict internet access.
B
Add a firewall rule for the office IP range. Enable auditing with SCHEMA_OBJECT_CHANGE_GROUP.
Why wrong: Missing TLS enforcement.
C
Set the minimal TLS version to 1.2. Add a firewall rule for the office IP range and remove the default 'Allow Azure services' rule. Enable auditing with SCHEMA_OBJECT_CHANGE_GROUP.
All requirements met.
D
Add a firewall rule for the office IP range. Remove the default 'Allow Azure services' rule.

Correct answer & explanation
✓
Set the minimal TLS version to 1.2. Add a firewall rule for the office IP range and remove the default 'Allow Azure services' rule. Enable auditing with SCHEMA_OBJECT_CHANGE_GROUP.
Option C is correct because it addresses all remaining requirements: (1) Set minimal TLS version to 1.2; (2) Add firewall rule for office IP only; (3) Enable auditing with SCHEMA_OBJECT_CHANGE_GROUP; (4) TDE already enabled. Option A is incorrect because it does not include firewall restrictions. Option B is incorrect because it does not enforce TLS. Option D is incorrect because it does not include auditing.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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 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.
