- A
Enable soft delete with a retention period of 30 days and configure a lifecycle management rule to delete blobs older than 90 days
Correct: Soft delete enables recovery within 30 days, and lifecycle management automatically deletes files older than 90 days.
- B
Create an Azure Policy to enforce tag-based retention and use Azure Monitor to alert on access
Why wrong: Incorrect: Azure Policy can enforce tags but does not provide file recovery or lifecycle management.
- C
Enable versioning and configure a retention policy in Azure Policy
Why wrong: Incorrect: Versioning is not native to ADLS Gen2 for recovery, and Azure Policy does not manage retention schedules.
- D
Use Azure Backup for the storage account and manually delete old files
Why wrong: Incorrect: Azure Backup is for disaster recovery, not age-based deletion, and manual deletion increases administrative effort.
DP-203 Soft delete Practice Question
This DP-203 practice question tests your understanding of secure, monitor, and optimize data storage and data processing. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. A key principle to apply: soft delete. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"minimum / minimize"Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
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
Option A is correct. 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.

Common exam traps
Common exam trap: answer the scenario, not the keyword
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.

TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Soft delete
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
