Question 8/57

Which solution will meet these requirements MOST cost-effectively?
Which solution will meet these requirements MOST cost-effectively?
Correct Answer: D

This approach minimizes storage costs due to the efficient compression of Parquet, and optimizes query performance and cost in Athena due to the reduced data size and optimized columnar storage.
