Develop for Azure storage →easyMultiple ChoiceObjective-mapped

Quick Answer

The correct approach is to configure a lifecycle management policy that transitions blobs to the cool tier after 7 days and deletes them after 30 days. This works because Azure Blob Storage lifecycle management policies automate tier transitions and deletion based on age, allowing you to define rules that move data to cheaper storage when access patterns shift and remove it entirely when retention expires—all without manual intervention. On the AZ-204 exam, this scenario tests your understanding of cost optimization through automated storage tiers, often appearing as a distractor where candidates might mistakenly suggest manual tiering or a separate archiving service like Azure Archive Storage. A common trap is forgetting that lifecycle policies can chain multiple actions (tier then delete) within a single rule, or assuming you need a separate logic app. Memory tip: think “7 cool, 30 gone” to remember the sequence—transition first, then delete, matching the lifecycle management policy’s ability to handle both actions in one automated rule.

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.

You store application logs in Azure Blob Storage. The logs are accessed frequently for the first 7 days, then rarely. After 30 days, they must be deleted to minimize cost. Which approach should you use?

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.

Question 1easymultiple choice

Full question →

A
Manually move blobs to cool tier after 7 days and delete after 30 days using a script
Why wrong: Manual scripting is error-prone and does not scale; Azure provides automated lifecycle management.
B
Use blob snapshots and delete snapshots after 30 days
Why wrong: Snapshots are for versioning, not for managing access tiers or automated deletion based on age.
C
Configure a lifecycle management policy to tier to cool after 7 days and delete after 30 days
Lifecycle management policies automatically transition blobs between tiers and delete them based on rules, reducing cost and management overhead.
D
Use Azure Data Factory to copy old logs to archive storage and delete original
Why wrong: Data Factory is for data integration pipelines, not for ongoing lifecycle management; lifecycle policies are simpler and cheaper.

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

✓

Configure a lifecycle management policy to tier to cool after 7 days and delete after 30 days

Option C is correct because Azure Blob Storage lifecycle management policies allow you to automatically transition blobs to a cooler tier (cool) after a specified number of days and then delete them after another period, all without manual intervention or additional services. This directly meets the requirement of frequent access for 7 days, rare access afterward, and deletion at 30 days, minimizing cost by leveraging tiered storage and automated rules.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates may overcomplicate the solution by choosing manual scripting (A) or a heavy orchestration tool (D), missing that Azure provides a native, policy-driven mechanism (lifecycle management) specifically designed for automated tiering and deletion based on age.

Detailed technical explanation

How to think about this question

Lifecycle management policies in Azure Blob Storage are defined as JSON rules that apply to a storage account, supporting actions like 'tierToCool' (after creation/modification) and 'delete' (based on age). The policy evaluates blobs daily, and the 'daysAfterModificationGreaterThan' property uses the blob's Last-Modified time, which is crucial for logs that are appended or updated. In real-world scenarios, this automation ensures compliance with data retention regulations without manual overhead, and the cool tier offers lower storage costs with slightly higher access costs, ideal for rarely accessed data.

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.
