DEA-C02 Data Movement Practice Question
A data engineer needs to load data from an Azure Blob storage container into Snowflake. The organization requires a secure connection that does not use public endpoints. What should the engineer configure?
⚠ Common exam trap
Candidates often suggest public endpoints or simple credentials. They miss the requirement for a 'storage integration' combined with 'Private Link' to strictly avoid the public internet as requested.
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
✓
Create a storage integration using an Microsoft Entra ID service principal and Private Link.
Using Azure Private Link with a Snowflake storage integration is the recommended method for secure, private data movement. This architecture ensures that traffic between Azure and Snowflake stays on the private network, bypassing the public internet and meeting strict compliance requirements for enterprise security. This question highlights the importance of cloud networking fundamentals in the context of data engineering and secure cloud-to-cloud integrations.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure an Azure Service Bus to relay the data to Snowflake.
Why it's wrong here
Azure Service Bus is a messaging service for decoupled applications and is not designed for bulk data ingestion into Snowflake. Using it for data movement would be architecturally incorrect, introduce significant latency, and fail to leverage Snowflake's native, optimized storage integration features for secure cloud data transfer.
- ✓
Create a storage integration using an Microsoft Entra ID service principal and Private Link.
Why this is correct
Storage integrations are the secure way to access cloud storage without hardcoding credentials. When combined with Azure Private Link, they establish a dedicated, private connection that ensures data movement stays within the cloud provider's backbone, satisfying security requirements by removing reliance on public internet traffic for data transfers.
- ✗
Use a public URL for the stage but enable IP whitelisting.
Why it's wrong here
IP whitelisting only controls who can access the database; it does not secure the transit path of the data itself. Using public URLs exposes data to the public internet, which violates the requirement for private connectivity regardless of whether specific IP addresses are permitted to access the final destination.
- ✗
Use an external stage with a SAS token that has a long expiration time.
Why it's wrong here
SAS tokens are a less secure method of access compared to storage integrations. They are difficult to rotate and do not address the network security requirement. Relying on long-lived tokens increases the risk of unauthorized access if the token is compromised, violating the principle of least privilege security.
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 |
