DP-203 Certification Practice Question #140

Question

You are designing a solution that will copy Parquet files stored in an Azure Blob storage account to an Azure Data Lake Storage Gen2 account.
The data will be loaded daily to the data lake and will use a folder structure of {Year}/{Month}/{Day}/.
You need to design a daily Azure Data Factory data load to minimize the data transfer between the two accounts.
Which two configurations should you include in the design? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point

Accepted Answer

To minimize daily transfer, the load should copy only files that changed since the prior run, which is exactly what last-modified filtering is for. The destination also has an explicit `{Year}/{Month}/{Day}` organization requirement, so the design must include a naming/path pattern for the sink. Deleting files in either location may be an operational choice, but it is not the core mechanism that minimizes data transferred each day. That makes **A + C** the best-supported answer.
