DP-300 Implement a secure environment Practice Question
Which TWO of the following are valid methods to secure data in transit for Azure SQL Database?
⚠ Common exam trap
Test-takers frequently confuse data-in-transit security with network access controls (like firewalls or NSGs) or client-side encryption (like Always Encrypted), failing to recognize that enforcing TLS 1.2 is the direct method to secure the communication channel itself.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure the server to enforce TLS 1.2 by setting minimal TLS version.
Azure SQL Database allows you to enforce a minimum TLS version, such as TLS 1.2, which ensures that all client connections use at least that protocol version. This directly secures data in transit by preventing downgrade attacks and blocking older, less secure TLS versions like TLS 1.0 or 1.1.
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 Always Encrypted on sensitive columns.
Why it's wrong here
Always Encrypted is for data in use, not in transit.
- ✗
Deploy Azure Firewall in front of the database.
Why it's wrong here
Azure Firewall provides network security but not encryption in transit.
- ✓
Configure the server to enforce TLS 1.2 by setting minimal TLS version.
Why this is correct
Enforcing TLS 1.2 ensures encryption in transit.
- ✓
Use an Azure Virtual Network (VNet) with a VPN gateway for client connections.
Why this is correct
VPN encrypts traffic between client and VNet.
- ✗
Apply a Network Security Group (NSG) to the subnet.
Why it's wrong here
NSGs filter traffic but do not encrypt.
