DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing
Your company uses Azure Data Lake Storage Gen2 with hierarchical namespace enabled. You need to optimize costs for a large dataset that is accessed only once a month for reporting. The data must be retained for 7 years. Which storage tier and lifecycle management rule should you configure?
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
✓
Cool tier with lifecycle policy to Archive after 30 days
Cool tier is cost-effective for data accessed infrequently (once a month), and a lifecycle policy to move data to Archive after 30 days further reduces costs while meeting the 7-year retention requirement. Option A (Hot tier) is expensive for infrequent access. Option C (Premium tier) is designed for high-throughput workloads, not cost optimization. Option D (Archive tier with no lifecycle) incurs high retrieval costs for monthly access and doesn't leverage tiering.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Hot tier with no lifecycle policy
Why it's wrong here
Hot tier is costly for infrequent access.
- ✓
Cool tier with lifecycle policy to Archive after 30 days
Why this is correct
Cool tier balances cost and access; Archive after 30 days reduces cost further.
- ✗
Premium tier with lifecycle policy to Cool after 30 days
Why it's wrong here
Premium tier is designed for high performance, not cost optimization.
- ✗
Archive tier with no lifecycle policy
