The correct answer is to set the 'Force Encryption' option to Yes on the server properties of the Azure SQL Managed Instance. This configuration enforces Transport Layer Security (TLS) for all client connections, meaning any client attempting to connect without encryption will be rejected at the instance level, regardless of the client's own encryption settings. On the DP-300 exam, this scenario tests your understanding of server-level encryption enforcement versus client-side options like "Encrypt=True" in connection strings—a common trap is assuming that client-side configuration alone is sufficient, but the exam emphasizes that only the server-side "Force Encryption" setting guarantees encrypted connections for all users. Remember the mnemonic "Force from the Source": to force encrypted connections, the enforcement must come from the source (the instance), not 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.
You are a database administrator for an Azure SQL Managed Instance. You need to ensure that all connections to the instance use encrypted connections. 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' option to Yes on the server properties.
Option A is correct because setting 'Force Encryption' to Yes on the Azure SQL Managed Instance server properties enforces the use of TLS (Transport Layer Security) for all client connections. This configuration ensures that any client attempting to connect without encryption will be rejected, thereby meeting the requirement that all connections use encrypted connections. The setting is applied at the instance level and overrides client-side encryption preferences.
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' option to Yes on the server properties.
Why this is correct
This enforces encrypted connections.
Related concept
Read the scenario before looking for a memorised answer.
Always Encrypted protects specific columns in transit and at rest, but does not enforce connection encryption.
✗
Configure a firewall rule to allow only specific IP addresses.
Why it's wrong here
Firewall rules control network access, not encryption.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse encryption in transit (Force Encryption) with encryption at rest (TDE) or column-level encryption (Always Encrypted), leading them to select a security feature that does not address the specific requirement of encrypting all connections.
Detailed technical explanation
How to think about this question
The 'Force Encryption' setting works by requiring the server to negotiate TLS for every login packet; if the client does not support TLS or requests an unencrypted connection, the server will refuse the connection. Under the hood, this corresponds to setting the `SECURE` flag in the server's network configuration, which forces the use of the TLS protocol (typically TLS 1.2 or higher) for all TDS (Tabular Data Stream) sessions. In a real-world scenario, this is critical for compliance with standards like PCI DSS or HIPAA, which mandate encryption of data in transit.

TExam Day Tips
→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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
