The correct configuration is to set Force Encryption to ON and Trust Server Certificate to OFF. This combination ensures that all connections to Azure SQL Managed Instance are encrypted using TLS, while the OFF setting for Trust Server Certificate forces the client to validate the server’s certificate against a trusted certificate authority, providing both data-in-transit encryption and server identity verification essential for a mission-critical application. On the Microsoft Azure Database Administrator Associate DP-300 exam, this scenario tests your understanding of how to secure connections to managed instances, often appearing as a trap where candidates mistakenly set Trust Server Certificate to ON, which bypasses validation and exposes the system to man-in-the-middle attacks. Remember the key principle: for security, you never trust blindly—always verify. A helpful mnemonic is “Encrypt and Verify, Never Trust Blindly,” linking Force Encryption ON with Trust Server Certificate OFF.
DP-300 Implement a secure environment Practice Question
This DP-300 practice question tests your understanding of implement a secure environment. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Your company plans to use Azure SQL Managed Instance for a mission-critical application. You need to ensure that all connections to the database are encrypted and that the server's identity is verified. Which configuration should you enforce?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set 'Force Encryption' = ON and 'Trust Server Certificate' = OFF
Option B is correct because setting 'Force Encryption' = ON ensures that all connections to Azure SQL Managed Instance use TLS encryption, while setting 'Trust Server Certificate' = OFF forces the client to validate the server's certificate against a trusted certificate authority (CA). This combination guarantees both data-in-transit encryption and server identity verification, meeting the requirement for a mission-critical application.
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.
✗
Set 'Force Encryption' = OFF and 'Trust Server Certificate' = OFF
Why it's wrong here
Does not enforce encryption.
✓
Set 'Force Encryption' = ON and 'Trust Server Certificate' = OFF
Why this is correct
This ensures encryption and certificate validation.

✗
Set 'Force Encryption' = ON and 'Trust Server Certificate' = ON
Why it's wrong here
Trusting the server certificate without validation is insecure.
✗
Set 'Force Encryption' = OFF and 'Trust Server Certificate' = ON
Why it's wrong here
Does not enforce encryption and trusts any certificate.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse 'Trust Server Certificate' = ON as a convenience setting that simplifies connections, not realizing it disables certificate validation and undermines security for mission-critical workloads.
Detailed technical explanation
How to think about this question
When 'Force Encryption' is ON, the SQL Server client driver (e.g., Microsoft.Data.SqlClient) negotiates TLS 1.2 or higher, and the server presents its certificate. With 'Trust Server Certificate' = OFF, the client validates the certificate chain against the Windows Certificate Store or a specified CA, ensuring the server's identity is authentic. In Azure SQL Managed Instance, the server certificate is issued by a Microsoft CA, so validation succeeds without additional configuration, but disabling it (Trust Server Certificate = ON) would expose the connection to spoofing risks in hybrid or cross-network scenarios.

→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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
