DP-203 Practice Question: Using Azure Data Factory to copy data from an…
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?
⚠ Common exam trap
It's easy for candidates to 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.

Correct answer & explanation
✓
The typeProperties property in the linked service to include 'Encrypt=True' in the connection string
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.
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.
Quick reference
Azure Blob Storage Tier Comparison
| Tier | Storage Cost | Retrieval Cost | Latency | Use Case |
|---|---|---|---|---|
| Hot | Highest | Lowest | Immediate | Active data, frequent reads |
| Cool | Lower | Higher | Immediate | Data accessed < once / month |
| Cold | Lower still | Higher | Immediate | Data accessed < once / quarter |
| Archive | Lowest | Highest + rehydration delay | Hours | Long-term compliance retention |
