DP-203 Design and implement data storage Practice Question
You are designing a solution to store large amounts of log data that is written once and accessed rarely. The data must be retained for 7 years for compliance. After 30 days, the data should be moved to a lower-cost storage tier. After 1 year, the data should be archived. Which Azure Storage lifecycle management policy should you implement for an Azure Data Lake Storage Gen2 account?
⚠ Common exam trap
A common mix-up: candidates confuse the required tiering order (cool then archive) with direct archiving after 30 days (Option C) or fail to include a deletion rule (Option D), missing the 7-year compliance requirement.

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
✓
Transition to cool tier after 30 days; transition to archive tier after 365 days; delete after 2555 days (7 years).
It aligns with the specified lifecycle requirements: transition to cool tier after 30 days for cost savings, transition to archive tier after 365 days for long-term retention, and delete after 2555 days (7 years) for compliance. Azure Data Lake Storage Gen2 supports lifecycle management policies that automate tier transitions and deletion based on age, ensuring data is moved to lower-cost storage as access patterns change.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Transition to cool tier after 30 days; delete after 7 years.
Why it's wrong here
Does not archive after 1 year; deletion may not be needed if compliance requires retention.
- ✓
Transition to cool tier after 30 days; transition to archive tier after 365 days; delete after 2555 days (7 years).
Why this is correct
Matches the requirements exactly.
- ✗
Transition to archive tier after 30 days; delete after 7 years.
Why it's wrong here
Skips cool tier; archive after 30 days incurs early deletion fee if accessed before 180 days.
- ✗
Transition to cool tier after 30 days; transition to cool tier again after 365 days.
Why it's wrong here
Transition to cool twice is redundant; archive tier is needed.
