Full question →mediummultiple choiceObjective-mapped
A company ingests IoT sensor data into Azure Blob Storage. Data is written frequently and is accessed rarely after the first 24 hours. The company must retain the data for exactly 90 days for compliance. They want to minimize storage costs by automatically moving data to the cheapest possible storage tier as soon as possible. Which Azure Blob Storage lifecycle management policy should they implement?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Move to Cool tier after 1 day, delete after 90 days
Cool tier is the most cost-effective for data accessed rarely. Moving after 1 day minimizes storage cost early. Deleting after exactly 90 days meets compliance without early deletion penalties.
B
Distractor review
Move to Archive tier after 1 day, delete after 90 days
Moving to Archive after 1 day would result in early deletion fees because the Archive tier requires a minimum 180-day retention. Deleting at 90 days would incur extra charges, making it more expensive.
C
Distractor review
Move to Cool tier after 30 days, delete after 90 days
Keeping data in the Hot tier for the first 30 days is unnecessary because data is rarely accessed after 24 hours. This results in higher costs for those 29 days compared to moving to Cool after 1 day.
D
Distractor review
Move to Archive tier after 30 days, delete after 90 days
Moving to Archive after 30 days leaves data in Hot for 30 days unnecessarily, and then Archive early deletion fees apply because 60 days in Archive is less than 180 days, increasing overall cost.
Common exam trap
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.
Technical deep dive
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.

FAQ
Questions learners often ask
What does this AZ-305 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Move to Cool tier after 1 day, delete after 90 days — The cheapest storage tier for data accessed rarely is the Cool tier (Hot is more expensive; Archive is cheaper but has a minimum retention penalty of 180 days and higher retrieval costs). Since the retention period is only 90 days, moving to Cool after 1 day and then deleting after 90 days is the most cost-effective. Moving to Archive after 1 day would incur early deletion fees because the data is deleted before 180 days. Moving to Cool after 30 days misses the opportunity to reduce costs for the 29 days after the first day. Moving to Archive after 30 days also incurs early deletion fees if deleted at 90 days (60 days in Archive, less than 180).
