- A
Move blobs to archive tier immediately after 30 days.
Why wrong: Moving directly to archive after 30 days makes data unavailable for immediate access and incurs high retrieval costs if needed, making it less cost-effective than D.
- B
Delete blobs after 30 days.
Why wrong: Deleting after 30 days violates the 7-year retention requirement, so this is incorrect.
- C
Move blobs to premium tier after 30 days.
Why wrong: The premium tier is for high-performance workloads, not cost savings on infrequently accessed data.
- D
Move blobs to cool tier after 30 days, then to archive tier after 1 year.
This is correct: cool tier after 30 days reduces costs for infrequent access, and archive after 1 year maximizes long-term savings while retaining data for 7 years.

DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing
This DP-203 practice question tests your understanding of secure, monitor, and optimize data storage and data processing. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. 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 optimizing cost for an Azure Data Lake Storage Gen2 account that stores historical data. The data is accessed infrequently after 30 days and must be retained for 7 years. Which lifecycle management rule should you apply?
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
✓
Move blobs to cool tier after 30 days, then to archive tier after 1 year.
Option D is correct because it moves blobs to the cool tier after 30 days (saving costs for infrequent access) and then to the archive tier after 1 year (maximizing savings for long-term retention), meeting both the access pattern and 7-year retention requirement. Option A is wrong because moving directly to archive after 30 days makes data unavailable for immediate access and incurs high retrieval costs if needed. Option B is wrong because deleting after 30 days violates the 7-year retention policy. Option C is wrong because the premium tier is designed for high performance, not cost savings on cold data.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Move blobs to archive tier immediately after 30 days.
Why it's wrong here
Moving directly to archive after 30 days makes data unavailable for immediate access and incurs high retrieval costs if needed, making it less cost-effective than D.
- ✗
Delete blobs after 30 days.
Why it's wrong here
Deleting after 30 days violates the 7-year retention requirement, so this is incorrect.
- ✗
Move blobs to premium tier after 30 days.
Why it's wrong here
The premium tier is for high-performance workloads, not cost savings on infrequently accessed data.
- ✓
Move blobs to cool tier after 30 days, then to archive tier after 1 year.
Why this is correct
This is correct: cool tier after 30 days reduces costs for infrequent access, and archive after 1 year maximizes long-term savings while retaining data for 7 years.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
Quick reference
Azure Blob Storage Tier Comparison
| Tier | Storage Cost | Retrieval Cost | Latency | Use Case |
|---|---|---|---|---|
| Hot | Highest | Lowest | Immediate | Active data, frequent reads |
| Cool | Lower | Higher | Immediate | Data accessed < once / month |
| Cold | Lower still | Higher | Immediate | Data accessed < once / quarter |
| Archive | Lowest | Highest + rehydration delay | Hours | Long-term compliance retention |
