DP-203 Practice Question: Which TWO actions help optimize data storage…
Which TWO actions help optimize data storage costs in Azure Data Lake Storage Gen2?
⚠ Common exam trap
Watch out — candidates often confuse cost-optimization features (like tiering) with data protection or security features (like soft delete, GRS, or encryption), which serve different purposes and may actually increase costs.
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
✓
Configure lifecycle management policies to move data to cool or archive tiers.
Azure Data Lake Storage Gen2 supports lifecycle management policies that automatically transition data to cooler tiers (cool or archive) based on age or usage patterns. Moving infrequently accessed data to lower-cost tiers directly reduces storage costs without manual intervention.
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 for blobs.
Why it's wrong here
Soft delete increases cost by retaining deleted data.
- ✗
Enable geo-redundant storage (GRS) for the storage account.
Why it's wrong here
Geo-redundancy increases cost due to replication.
- ✓
Configure lifecycle management policies to move data to cool or archive tiers.
Why this is correct
Lifecycle policies reduce cost by tiering infrequently accessed data.
- ✗
Enable encryption at rest using customer-managed keys.
Why it's wrong here
Encryption does not reduce storage cost.
- ✓
Use locally redundant storage (LRS) for temporary data.
Why this is correct
LRS is cheaper than other redundancy options.
