Describe considerations for working with non-relational data on Azure →mediumMultiple ChoiceObjective-mapped

Quick Answer

The correct answer is to move blobs from Hot to Cool after 30 days, then to Archive after 2 years. This policy directly aligns with the described access pattern: frequent reads for the first month justify the Hot tier, infrequent access over the next two years makes Cool the cost-effective choice, and the final seven-year compliance retention with rare access is best served by the Archive tier, which offers the lowest storage cost at the expense of higher retrieval latency. On the DP-900 exam, lifecycle management questions test your ability to map business requirements—like retention periods and access frequency—to the correct tier transitions; a common trap is forgetting that Archive requires rehydration before reading, so it is only suitable for data that is truly rarely accessed. To remember the flow, think of a staircase: Hot at the top for active use, Cool in the middle for occasional use, and Archive at the bottom for long-term cold storage.

DP-900 Practice Question: Describe considerations for working with non-relational data on Azure

This DP-900 practice question tests your understanding of describe considerations for working with non-relational data on azure. 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.

A company stores customer support chat transcripts as plain text files in Azure Blob Storage. The files are accessed frequently for the first 30 days, then infrequently for the next 2 years, and after that must be retained for 7 years for compliance but are rarely accessed. The company wants to minimize storage costs by automatically moving data through appropriate access tiers. Which Azure Blob Storage lifecycle management policy should they implement?

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.

A
Move blobs from Hot to Cool after 30 days, then to Archive after 2 years
This policy correctly matches the access pattern: Hot tier for frequent initial access, Cool for infrequent intermediate access (still retained for 2 years but accessed rarely), and Archive for long-term compliance retention where data is rarely accessed and retrieval latency is acceptable.
B
Store all data in Hot tier for the full retention period
Why wrong: Hot tier is the most expensive and is intended for frequently accessed data. Storing rarely accessed compliance data in Hot tier would result in unnecessary costs.
C
Move blobs from Hot to Archive after 30 days and delete after 2 years
Why wrong: Moving directly to Archive after 30 days would increase retrieval time for data that is still accessed occasionally. Deleting after 2 years violates the 7-year compliance requirement.
D
Store all data in Cool tier for the first 30 days, then move to Archive
Why wrong: Cool tier has higher retrieval costs and latency compared to Hot; placing frequently accessed data in Cool would degrade performance and potentially increase costs due to early deletion fees if data is accessed often.

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

✓

Move blobs from Hot to Cool after 30 days, then to Archive after 2 years

Option A is correct because the lifecycle management policy matches the access pattern: move blobs from Hot (frequent access for first 30 days) to Cool (infrequent access for next 2 years) after 30 days, then to Archive (rare access for 7-year compliance) after 2 years. This minimizes storage costs by using the cheapest tier for each phase while retaining data for the required 7-year compliance period.

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

✓
Move blobs from Hot to Cool after 30 days, then to Archive after 2 years
Why this is correct
This policy correctly matches the access pattern: Hot tier for frequent initial access, Cool for infrequent intermediate access (still retained for 2 years but accessed rarely), and Archive for long-term compliance retention where data is rarely accessed and retrieval latency is acceptable.
Clue confirmation
The clue words "first", "minimum / minimize" in the question point toward this answer.

✗
Store all data in Hot tier for the full retention period
Why it's wrong here
Hot tier is the most expensive and is intended for frequently accessed data. Storing rarely accessed compliance data in Hot tier would result in unnecessary costs.
✗
Move blobs from Hot to Archive after 30 days and delete after 2 years
Why it's wrong here
Moving directly to Archive after 30 days would increase retrieval time for data that is still accessed occasionally. Deleting after 2 years violates the 7-year compliance requirement.
✗
Store all data in Cool tier for the first 30 days, then move to Archive
Why it's wrong here
Cool tier has higher retrieval costs and latency compared to Hot; placing frequently accessed data in Cool would degrade performance and potentially increase costs due to early deletion fees if data is accessed often.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates may overlook the rehydration latency of the Archive tier and incorrectly move data to Archive during a period of frequent access, or fail to account for the full compliance retention period when choosing deletion actions.

Detailed technical explanation

How to think about this question

Azure Blob Storage lifecycle management policies evaluate blob creation time or last modification time to apply actions like tier changes or deletion. The Archive tier has a 180-day minimum storage duration for blobs smaller than 130 GB, so moving from Cool to Archive after 2 years avoids early deletion fees. In practice, the 7-year compliance retention can be enforced with immutable storage policies (WORM) or legal holds, independent of the lifecycle tier transitions.

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.
