PDE Ingesting and Processing the Data Practice Question
An organization needs to transfer 50 TB of historical data from an on-premises Hadoop cluster to Google Cloud Storage. The network bandwidth is limited to 100 Mbps. Which transfer method is MOST cost-effective and time-efficient?
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
✓
Transfer Appliance
Transfer Appliance is designed for petabyte-scale offline transfers, shipping physical devices to Google for upload, which is much faster than using limited network bandwidth for 50 TB.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Transfer Appliance
Why this is correct
Transfer Appliance allows shipping data physically, bypassing network bandwidth limitations for large datasets.
- ✗
Storage Transfer Service over the network
Why it's wrong here
At 100 Mbps, transferring 50 TB would take over 45 days, which is not time-efficient.
- ✗
BigQuery Data Transfer Service for Hadoop
Why it's wrong here
BigQuery Data Transfer Service does not support Hadoop as a source.
- ✗
gsutil cp with parallel composite uploads
Why it's wrong here
gsutil is still limited by network bandwidth and would take too long.
