DP-203 Develop data processing Practice Question
You are implementing a data processing solution in Azure Databricks. The solution must read data from Azure Data Lake Storage Gen2, transform it using PySpark, and write the results back to a different location in the same storage account. You need to authenticate to the storage account securely without storing secrets in the notebook. What should you use?

Correct answer & explanation
✓
Azure Key Vault-backed secret scope
Azure Key Vault-backed secret scopes allow you to securely reference secrets without storing them in the notebook. Option A is wrong because storing a client secret directly in the notebook is insecure. Option C is wrong because SAS tokens can be exposed and are less secure. Option D is wrong because storage account access keys are long-lived and should not be used in notebooks.
