DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing
You are designing a data pipeline in Azure Data Factory that processes streaming data from Azure Event Hubs and stores it in Azure Data Lake Storage Gen2. The data must be encrypted at rest and in transit. Which configuration ensures encryption in 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
✓
Use HTTPS endpoint for Azure Data Lake Storage Gen2.
HTTPS ensures encryption in transit for Azure Data Lake Storage Gen2. Option A is wrong because encryption at rest does not cover data in transit. Option C is wrong because while TLS 1.2 is important, the integration runtime configuration does not directly apply to the storage endpoint; the storage account itself must use HTTPS. Option D is wrong because Azure Firewall does not provide encryption; it filters traffic.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable encryption at rest using Azure Storage Service Encryption.
Why it's wrong here
Encryption at rest protects stored data, not data in transit.
- ✓
Use HTTPS endpoint for Azure Data Lake Storage Gen2.
Why this is correct
HTTPS (HTTP over TLS) encrypts data in transit between clients and Azure Data Lake Storage Gen2.
- ✗
Configure the Azure Data Factory integration runtime to use TLS 1.2.
Why it's wrong here
Configuring the integration runtime to use TLS 1.2 is a good practice but does not guarantee encryption for the storage endpoint; the storage account must enforce HTTPS.
- ✗
Deploy Azure Firewall to inspect traffic between Event Hubs and Data Lake.
Why it's wrong here
Azure Firewall provides network security but does not encrypt traffic.
