- A
Set the access tier to Cool on the container
Why wrong: This would move all blobs to Cool immediately, not after 30 days, which does not meet the requirement of keeping blobs hot for the first 30 days.
- B
Use Azure Blob Storage lifecycle management rules
Lifecycle management allows you to create a rule that moves blobs older than 30 days to the Cool tier automatically, while keeping newer blobs in the Hot tier.
- C
Manually change the access tier every 30 days
Why wrong: Manual operations are not automated and are prone to errors. Azure provides automated lifecycle management to handle this at scale.
- D
Use Azure Policy to enforce tier changes
Why wrong: Azure Policy is for enforcing compliance rules (e.g., tagging), not for automating data tier transitions based on age.
AZ-305 Design data storage solutions Practice Question
This AZ-305 practice question tests your understanding of design data storage solutions. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
A company stores website static assets in Azure Blob Storage. The assets are updated weekly and must be available for immediate access for 30 days. After 30 days, older versions can be moved to the Cool tier to save costs but must still be accessible within seconds. They want an automated solution. What should they configure?
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
Use Azure Blob Storage lifecycle management rules
Azure Blob Storage lifecycle management rules allow you to automate tier transitions based on age or last modification time. By configuring a rule to move blobs to the Cool tier 30 days after creation, you meet the requirement for immediate access (Cool tier offers sub-second latency) while optimizing costs without manual intervention.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✓
Use Azure Blob Storage lifecycle management rules
Why this is correct
Lifecycle management allows you to create a rule that moves blobs older than 30 days to the Cool tier automatically, while keeping newer blobs in the Hot tier.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing Azure Policy (which enforces configuration at resource creation) with lifecycle management (which automates transitions based on time), leading candidates to choose Policy when only lifecycle rules can schedule tier changes.
Detailed technical explanation
How to think about this question
Lifecycle management rules are evaluated once per day and apply to blobs at the base blob level (not snapshots or versions unless explicitly included). The Cool tier provides the same sub-second access latency as Hot but with lower storage costs and higher access costs, making it ideal for data accessed infrequently but requiring immediate retrieval. A common real-world scenario is managing static website assets where older versions are rarely accessed but must remain available for compliance or rollback.
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.
