DP-203 Develop data processing Practice Question
Which TWO data processing activities in Azure Data Factory allow you to run custom code?
⚠ Common exam trap
Many candidates confuse the Custom activity with the Azure Function activity, thinking both run custom code, but the question asks for 'custom code' in the context of ADF's native activities—Azure Function activity is also correct because it runs custom code via an Azure Function, making it a valid choice alongside Custom activity.

Correct answer & explanation
✓
Custom activity
The Custom activity in Azure Data Factory allows you to execute custom code by running a .NET or PowerShell script in an Azure Batch service. This enables you to implement complex transformation logic that is not natively supported by ADF's built-in activities, such as custom data validation or integration with third-party APIs.
