Exam DP-203 topic 2 question 106 discussion

Just use Built-in copy task, according to: https://learn.microsoft.com/en-us/azure/data-factory/tutorial-incremental-copy-lastmodified-copy-data-tool

"[...] use the Copy Data tool to create a pipeline that incrementally copies new and changed files only, from Azure Blob storage to Azure Blob storage. It uses LastModifiedDate to determine which files to copy." https://learn.microsoft.com/en-us/azure/data-factory/tutorial-incremental-copy-lastmodified-copy-data-tool

While the Built-in copy task is useful for simpler scenarios, it does not inherently support metadata-driven incremental copy, which is key to meeting the requirements.

This option provides a minimal effort solution and can automatically track changes. why not D : The Built-in copy task is a straightforward approach in Azure Data Factory to copy data from one source to a destination. However, this does not inherently include metadata tracking like the metadata-driven copy task does.

correct according to doc

vote for D

A. Run the Copy Data tool and select Metadata-driven copy task. Explanation: The Metadata-driven copy task in Azure Data Factory allows you to dynamically define and manage data movement and transformation tasks based on metadata. This includes copying only blobs that were created or modified since the most recent replication event, which aligns with the requirements. This solution minimizes the effort to create the pipeline, as you can configure the replication task based on metadata properties such as the creation or modification timestamp of the blobs. The Built-in copy task also provides a solution for data movement but may require more manual effort to configure the incremental replication based on timestamps

The built-in copy task leads you to create a pipeline within five minutes to replicate data without learning about entities. The metadata driven copy task to ease your journey of creating parameterized pipelines and external control table in order to manage to copy large amounts of objects (for example, thousands of tables) at scale.

Metadata-driven copy task (A): The Metadata-driven copy task in the Copy Data tool of Azure Data Factory allows you to replicate data based on changes in metadata. This includes the ability to only copy blobs that were created or modified since the last replication event. Given the requirements to replicate blobs based on changes in metadata and to minimize effort, the Metadata-driven copy task is a suitable choice.

A is correct because of the requirement "Minimize the effort to create the pipeline."

D is correct

Create a data factory. Use the Built-in Copy Data tool to create a pipeline. Monitor the pipeline and activity runs.
