DP-300 Implement a secure environment Practice Question
Your Azure SQL Managed Instance stores sensitive financial data. You must prevent unauthorized access from Azure services and ensure that only specific virtual networks can connect. You also need to audit all failed login attempts. Which combination of configurations should you implement?
⚠ Common exam trap
A common mix-up: candidates confuse VNet service endpoints with private endpoints, assuming service endpoints provide the same level of isolation and access control, but service endpoints still leave the resource publicly resolvable and do not block all Azure service traffic.
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
✓
Create a private endpoint, set 'Public network access' to 'Deny', and enable Azure SQL Auditing with a log analytics workspace.
Creating a private endpoint for Azure SQL Managed Instance ensures that traffic to the instance traverses the Microsoft backbone network and is only accessible from within the specified virtual network. Setting 'Public network access' to 'Deny' explicitly blocks all public internet traffic, including traffic from other Azure services that do not originate from the approved VNet. Enabling Azure SQL Auditing with a Log Analytics workspace captures all failed login attempts, meeting the audit requirement. This combination directly addresses the need to prevent unauthorized access from Azure services and enforce VNet-only connectivity while auditing failed logins.
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 Microsoft Defender for SQL and set up anomaly detection alerts.
Why it's wrong here
Defender detects threats but does not provide login auditing.
- ✓
Create a private endpoint, set 'Public network access' to 'Deny', and enable Azure SQL Auditing with a log analytics workspace.
Why this is correct
Private endpoint with public access denied secures network; auditing logs failed logins.
- ✗
Enable SQL vulnerability assessment and configure email notifications.
Why it's wrong here
Vulnerability assessment does not audit login attempts.
- ✗
Configure VNet service endpoints and set the firewall to allow only your VNet.
Why it's wrong here
Service endpoints do not block all public access; an additional deny firewall rule is needed.
