DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing
You are designing a data pipeline in Azure Data Factory that copies data from Azure Blob Storage to Azure SQL Database. The data contains personally identifiable information (PII). What should you use to protect the data during transit?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Encryption over HTTPS/TLS
Azure Data Factory always encrypts data in transit using TLS. Option A is wrong because Azure Information Protection is for labeling, not transit encryption. Option C is wrong because Azure Disk Encryption is for at-rest encryption of disks. Option D is wrong because Azure Storage Service Encryption is for at-rest encryption.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Azure Information Protection
Why it's wrong here
Azure Information Protection is for classification and labeling, not for encrypting data in transit.
- ✓
Encryption over HTTPS/TLS
Why this is correct
Azure Data Factory uses TLS to encrypt data in transit between endpoints.
- ✗
Azure Disk Encryption
Why it's wrong here
Azure Disk Encryption encrypts disks, not network traffic.
- ✗
Azure Storage Service Encryption
Why it's wrong here
Azure Storage Service Encryption encrypts data at rest, not in transit.
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 |

Same concept, more angles
1 more way this is tested on DP-203
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Your team uses Azure Data Factory to copy data from on-premises SQL Server to Azure Blob Storage. You need to ensure that data in transit is encrypted using TLS 1.2. What should you configure?
easy- ✓ A.Ensure the Azure Data Factory pipeline uses HTTPS for the copy activity.
- B.Set up a site-to-site VPN between the on-premises network and Azure.
- C.Configure the on-premises SQL Server to use SSL certificates.
- D.Use Azure ExpressRoute with private peering.
Why A: Azure Data Factory uses HTTPS by default, which enforces TLS encryption for data in transit. Option B is wrong because VPN is not required for TLS encryption. Option C is wrong because configuring the on-premises SQL Server to use SSL certificates is necessary but not sufficient; Azure Data Factory must also use HTTPS. Option D is wrong because Azure ExpressRoute provides a private connection but does not replace TLS.
