DP-203 Design and implement data security Practice Question
This DP-203 practice question tests your understanding of design and implement data security. 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.
A company is using Azure Data Factory to copy data from an on-premises SQL Server to Azure Blob Storage. The data must be encrypted in transit using TLS 1.2. The on-premises SQL Server is configured to support TLS 1.2. Which Data Factory property should be configured?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The typeProperties property in the linked service to include 'Encrypt=True' in the connection string
Option B is correct because TLS 1.2 encryption for data in transit between Azure Data Factory and an on-premises SQL Server is enforced by adding 'Encrypt=True' and 'TrustServerCertificate=False' to the connection string within the typeProperties of the linked service. This ensures the SQL Server Native Client uses TLS 1.2 for the connection, aligning with the requirement.
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.
✗
The encryptedCredential property in the linked service
Why it's wrong here
encryptedCredential stores encrypted credentials, not TLS settings.
✓
The typeProperties property in the linked service to include 'Encrypt=True' in the connection string
Why this is correct
The connection string in typeProperties can include 'Encrypt=True' to enforce TLS encryption.

✗
The connectVia property in the linked service
Why it's wrong here
connectVia specifies the integration runtime, not encryption.
✗
The integrationRuntime property in the dataset
Why it's wrong here
IntegrationRuntime specifies the runtime, not encryption settings.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse the encryptedCredential property (which encrypts stored credentials at rest) with the connection string encryption settings (which enforce TLS for data in transit), leading them to select Option A incorrectly.
Detailed technical explanation
How to think about this question
Under the hood, Azure Data Factory uses the SQL Server Native Client (SNAC) or ODBC driver to connect to SQL Server. The 'Encrypt=True' setting forces the driver to negotiate TLS 1.2 (or higher) by default, while 'TrustServerCertificate=False' ensures the server certificate is validated against a trusted CA. In real-world scenarios, if the on-premises SQL Server is behind a firewall or uses a self-signed certificate, you may need to set 'TrustServerCertificate=True' temporarily, but this weakens security.

Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.

What is the correct answer to this question?
The correct answer is: The typeProperties property in the linked service to include 'Encrypt=True' in the connection string — Option B is correct because TLS 1.2 encryption for data in transit between Azure Data Factory and an on-premises SQL Server is enforced by adding 'Encrypt=True' and 'TrustServerCertificate=False' to the connection string within the typeProperties of the linked service. This ensures the SQL Server Native Client uses TLS 1.2 for the connection, aligning with the requirement.
