The answer is to set the ‘Force Encryption’ property to True for the managed instance. This configuration enforces TLS encryption for all client connections to Azure SQL Managed Instance and ensures the server presents a certificate from a trusted public certificate authority (CA) to verify its identity, directly meeting both security requirements for encrypted data in transit and server identity verification. On the Microsoft Azure Database Administrator Associate DP-300 exam, this scenario tests your understanding of how to secure connections to Azure SQL Managed Instance, often appearing as a migration or compliance question where you must distinguish between client-side and server-side encryption settings. A common trap is confusing ‘Force Encryption’ with the client-side ‘Encrypt=True’ option, but remember that server-side enforcement is what guarantees the certificate validation and encryption for all connections. Memory tip: think of “Force” as the server’s command—it forces encryption and identity verification for everyone, not just the client.
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 is planning to migrate on-premises SQL Server databases to Azure SQL Managed Instance. The security team requires that all database connections be encrypted and that the server's identity be verified using a certificate from a trusted public certificate authority (CA). What should you configure?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set the 'Force Encryption' property to True for the managed instance.
Setting 'Force Encryption' to True on the managed instance enforces TLS encryption for all client connections and ensures the server presents a certificate from a trusted public CA to verify its identity. This meets both requirements: encryption of data in transit and server identity verification via a trusted certificate chain.
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 the 'Force Encryption' property to True for the managed instance.
Why this is correct
Correct: This ensures encryption for all connections, and the server certificate is from a trusted CA.
Related concept
Read the scenario before looking for a memorised answer.
✗
Install a custom CA-signed certificate on the managed instance.
Why it's wrong here
Incorrect: You cannot install custom certificates on Azure SQL Managed Instance.
✗
Enable Transparent Data Encryption (TDE) with a server certificate.
Why it's wrong here
Incorrect: TDE protects data at rest, not in transit.
✗
Configure Always Encrypted with column master key in Key Vault.
Why it's wrong here
Incorrect: Always Encrypted encrypts specific columns, not the connection.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse encryption in transit (Force Encryption/TLS) with encryption at rest (TDE) or column-level encryption (Always Encrypted), and mistakenly think a custom CA certificate is needed when Azure SQL Managed Instance already uses a trusted public CA certificate by default.
Detailed technical explanation
How to think about this question
When 'Force Encryption' is enabled, the server rejects any connection that does not use TLS, and the client validates the server's certificate against a trusted root CA (e.g., Baltimore CyberTrust Root). Under the hood, this uses the SChannel security provider in Windows and the TLS 1.2+ protocol, with the certificate presented during the TLS handshake. In a real-world scenario, if 'Force Encryption' is False, clients can connect without encryption, leaving data vulnerable to man-in-the-middle attacks.

Key takeaway

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.
