Databricks Certified Data Engineer Associate — Question 137

An organization plans to share a large dataset stored in a Databricks workspace on AWS with a partner organization whose Databricks workspace is hosted on Azure. The data engineer wants to minimize data transfer costs while ensuring secure and efficient data sharing.

Which strategy will reduce data egress costs associated with cross-cloud data sharing?

Answer options

• A. Migrating the dataset to Cloudflare R2 object storage before sharing
• B. Configure VPN connection between AWS and Azure for faster data sharing
• C. Using Delta Sharing without any additional configurations
• D. Sharing data via pre-signed URLs without monitoring egress costs

Correct answer: C

Explanation

The correct answer is C because Delta Sharing is designed to facilitate secure and efficient data sharing across clouds without incurring high egress costs. Options A and B introduce additional complexity and potential costs, while option D fails to monitor egress costs effectively, which could lead to unexpected expenses.
