Full question →easymultiple choiceObjective-mapped
A company stores log data in Azure Blob Storage. Logs are accessed frequently for the first 30 days, then rarely accessed but must be retained for 7 years for compliance. They want to minimize storage costs. Which storage tier and lifecycle management rule should they use?
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
Distractor review
Use the Cool tier for initial storage, and a lifecycle rule to move to Archive after 30 days.
Cool tier is for data accessed infrequently but with immediate availability. Using Cool for the first 30 days may increase cost compared to Hot because Cool has higher read costs and lower storage cost, but Hot is cheaper for frequent access. More importantly, the requirement is to minimize cost, and Hot then Archive is the optimal path.
B
Distractor review
Use the Hot tier for initial storage, and a lifecycle rule to move to the Cool tier after 30 days, then to Archive after 7 years.
Moving to Cool after 30 days adds complexity and cost (write operations to Cool) with no benefit since the data is rarely accessed and can go directly to Archive.
C
Best answer
Use the Hot tier for initial storage, and a lifecycle rule to move to Archive after 30 days.
Hot tier optimizes for frequent access during the first 30 days. Moving directly to Archive after 30 days minimizes storage cost during the long retention period, as Archive has the lowest storage cost for rarely accessed data.
D
Distractor review
Use the Archive tier for initial storage, and a lifecycle rule to move to Hot for the first 30 days.
Archive tier is for data that is rarely accessed and has a high retrieval cost and latency. Storing frequently accessed data in Archive is impractical and costly due to rehydration fees.
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: Use the Hot tier for initial storage, and a lifecycle rule to move to Archive after 30 days. — Blob lifecycle management can automatically move blobs between tiers. For logs accessed frequently for 30 days, the Hot tier is cost-effective for frequent access. After 30 days, moving directly to the Archive tier provides the lowest storage cost for long-term retention, as the data is rarely accessed. Moving to Cool first is unnecessary if the data is not accessed after 30 days.
