Quick Answer
The correct answer is to move blobs to cool tier after 30 days, then to archive tier after 1 year. This lifecycle management rule optimizes cost by aligning storage tiers with access patterns: infrequently accessed data after 30 days belongs in the low-cost cool tier, while data retained for 7 years but rarely accessed after the first year should transition to the cheapest archive tier. On the DP-203 exam, this scenario tests your understanding of Azure Blob Storage lifecycle policies and tier cost trade-offs, often appearing as a scenario where you must balance retention compliance against retrieval costs. A common trap is choosing immediate archive after 30 days, which incurs high retrieval fees for any unexpected access, or selecting deletion, which violates retention requirements. Remember the memory tip: "Cool after a month, archive after a year—keep it cheap, keep it clear."
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?
Move blobs to archive tier immediately after 30 days.
Why wrong: Too early; retrieval cost if accessed.
Delete blobs after 30 days.
Why wrong: Data must be retained.
Move blobs to premium tier after 30 days.
Why wrong: Premium is more expensive.
Move blobs to cool tier after 30 days, then to archive tier after 1 year.
Optimizes cost based on access patterns.
Answer choices
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 B is correct because moving blobs to cool tier after 30 days and then to archive after a longer period is cost-effective. Option A is wrong because deleting after 30 days loses data. Option C is wrong because premium tier is expensive. Option D is wrong because archive after 30 days would incur high retrieval costs.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
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
Too early; retrieval cost if accessed.
Delete blobs after 30 days.
Why it's wrong here
Data must be retained.
Move blobs to premium tier after 30 days.
Why it's wrong here
Premium is more expensive.
Move blobs to cool tier after 30 days, then to archive tier after 1 year.
Why this is correct
Optimizes cost based on access patterns.

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
