DP-203 Soft delete Practice Question
You are responsible for managing an Azure Data Lake Storage Gen2 account that stores parquet files for analytics. You need to implement a data retention policy that automatically deletes files older than 90 days in the 'logs' container. Additionally, you need to ensure that no data is lost due to accidental deletion; you want to be able to recover deleted files within 30 days. You also need to monitor the storage account for unusual access patterns. The solution must minimize administrative effort. What should you do?
⚠ Common exam trap
Candidates often confuse soft delete with versioning or Azure Policy. Remember that soft delete provides point-in-time recovery, while lifecycle management automates deletion based on age.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable soft delete with a retention period of 30 days and configure a lifecycle management rule to delete blobs older than 90 days
Enabling soft delete with a 30-day retention period allows recovery of accidentally deleted files within that window. Configuring a lifecycle management rule to delete blobs older than 90 days automatically enforces the retention policy. This combination minimizes administrative effort. Option B is incorrect because Azure Policy cannot enforce retention or recovery at the blob level. Option C is incorrect because versioning is not equivalent to soft delete for ADLS Gen2 and Azure Policy does not manage retention. Option D is incorrect because manual deletion does not provide automatic enforcement and Azure Backup is not designed for storage-level lifecycle management.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Enable soft delete with a retention period of 30 days and configure a lifecycle management rule to delete blobs older than 90 days
Why this is correct
Correct: Soft delete enables recovery within 30 days, and lifecycle management automatically deletes files older than 90 days.
- ✗
Create an Azure Policy to enforce tag-based retention and use Azure Monitor to alert on access
Why it's wrong here
Incorrect: Azure Policy can enforce tags but does not provide file recovery or lifecycle management.
- ✗
Enable versioning and configure a retention policy in Azure Policy
Why it's wrong here
Incorrect: Versioning is not native to ADLS Gen2 for recovery, and Azure Policy does not manage retention schedules.
- ✗
Use Azure Backup for the storage account and manually delete old files
Why it's wrong here
Incorrect: Azure Backup is for disaster recovery, not age-based deletion, and manual deletion increases administrative effort.
