DP-300 Minimum TLS Version Practice Question
Your company is deploying Azure SQL Database for a new application. The security policy requires that all queries be encrypted in transit and that the database be protected against accidental deletion. Which THREE configurations should you implement? (Select THREE.)
⚠ Common exam trap
Candidates often confuse encryption in transit (TLS) with encryption at rest (TDE) and may overlook the resource lock as a separate, required configuration for deletion protection. TDE does not protect against deletion, and TLS does not lock the resource.
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
✓
Set the minimum TLS version to 1.2
Setting the minimum TLS version to 1.2 ensures all connections are encrypted in transit. Enabling Microsoft Entra ID authentication provides secure identity-based access, a fundamental security practice even if not explicitly stated. A resource lock on the logical server prevents accidental deletion of the database and server.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Set the minimum TLS version to 1.2
Why this is correct
Ensures encrypted connections.
- ✗
Configure firewall rules to allow only specific IP addresses
Why it's wrong here
Firewall does not enforce encryption.
- ✓
Enable Microsoft Entra ID authentication
Why this is correct
Microsoft Entra ID authentication is required to securely authenticate users and applications, ensuring that only authorized identities can access the database. This is a key part of the overall security posture.
- ✗
Enable Transparent Data Encryption (TDE)
Why it's wrong here
Transparent Data Encryption (TDE) encrypts data at rest, which is not required by the security policy. The policy only requires encryption in transit and deletion protection, so TDE is not necessary.
- ✓
Enable a resource lock on the Azure SQL Database logical server
Why this is correct
Prevents accidental deletion.
