DA0-002 Data Acquisition and Preparation Practice Question
A data team needs to extract data from a legacy system that only supports flat file exports. Which data acquisition method is most appropriate?
⚠ Common exam trap
Watch out — candidates often confuse 'flat file exports' with a need for real-time or API-based methods, overlooking that SFTP is the standard secure file transfer protocol for batch-oriented legacy systems.
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
✓
File transfer via SFTP
The legacy system only supports flat file exports, meaning it cannot provide direct database or API access. SFTP (SSH File Transfer Protocol) is the most appropriate method because it securely transfers flat files over a network, aligning with the system's export capabilities while ensuring data integrity and encryption during transit.
