- A
Store in Hot tier and move to Cool after 1 year, then to Archive after 7 years.
Why wrong: Moving to Cool after 1 year is too late; the data is already rarely accessed. Also moving to Archive after 7 years is unnecessary because the retention period ends. The data should be in Archive for most of the retention.
- B
Store in Cool tier and move to Archive after 1 year.
Correct. Cool tier is sufficient for weekly access in the first year, and then Archive provides the lowest cost for the remaining 6 years when access is rare. Lifecycle management can automate the transition.
- C
Store directly in Archive tier and rehydrate to Cool when needed for access.
Why wrong: Archive tier requires costly and time-consuming rehydration to read. Since data is accessed weekly in the first year, Archive is not suitable for that period.
- D
Store in Hot tier and move to Archive after 90 days.
Why wrong: Moving to Archive after only 90 days would be too soon; data is still accessed weekly. Also Hot tier is more expensive than Cool for the first year.
AZ-204 Develop for Azure storage Practice Question
This AZ-204 practice question tests your understanding of develop for azure storage. 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.
Your company stores backup files in an Azure Blob Storage account. These files are written once and then need to be retained for 7 years. During the first year, the files are accessed weekly. After the first year, they are accessed rarely (once per month). You want to minimize storage costs. Which combination of access tiers and lifecycle management should you apply?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"first"Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Clue:
"minimum / minimize"Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
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
Store in Cool tier and move to Archive after 1 year.
Option B is correct because it minimizes costs by storing files in the Cool tier from the start (matching the initial weekly access pattern) and then moving them to the Archive tier after one year when access drops to monthly. The Cool tier offers lower storage cost than Hot for infrequent access, and the Archive tier provides the lowest storage cost for data that is rarely accessed and can tolerate a retrieval latency of up to 15 hours. This lifecycle policy aligns with the 7-year retention requirement without incurring unnecessary early deletion charges or rehydration costs.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
Archive tier requires costly and time-consuming rehydration to read. Since data is accessed weekly in the first year, Archive is not suitable for that period.

Why it's wrong here
Moving to Archive after only 90 days would be too soon; data is still accessed weekly. Also Hot tier is more expensive than Cool for the first year.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume the Hot tier is always the best starting point for any access pattern, ignoring that Cool tier is cheaper for data accessed less than once a month, and that Archive tier is not suitable for data that requires regular access within the first year due to its high rehydration latency and cost.
Detailed technical explanation
How to think about this question
Azure Blob Storage lifecycle management policies evaluate rules based on the 'last modification date' of the blob. When moving from Cool to Archive, the blob must remain in Cool for at least 30 days before transitioning to Archive to avoid an early deletion charge (equivalent to 30 days of Cool storage). The Archive tier has a retrieval time of up to 15 hours (standard priority) and requires rehydration to a readable tier (Hot or Cool) before access, which incurs both read and data transfer costs. In this scenario, the monthly access after year one is infrequent enough that the Archive tier's low storage cost outweighs the occasional rehydration cost.
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.
TExam Day Tips
- 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.
