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 sensor data in Azure Blob Storage. The data is appended every minute and rarely modified. The compliance team requires that blobs older than 90 days be moved to a more cost-effective storage tier, and blobs older than 365 days be deleted. Which solution should you recommend?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure a Blob Storage lifecycle management policy.
A lifecycle management policy can automatically transition blobs to cooler tiers (e.g., Cool after 90 days) and delete them after 365 days. Option B is wrong because Azure Files is for file shares. Option C is wrong because Blob Storage does not have a built-in backup retention policy for this scenario. Option D is wrong because Soft Delete is for recovery, not automated tiering or deletion.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Use Azure Backup to set a retention policy for the storage account.
Why it's wrong here
Azure Backup is for virtual machines and databases.
✓
Configure a Blob Storage lifecycle management policy.
Why this is correct
Lifecycle policies automate tiering and deletion.

Read the scenario before looking for a memorised answer.
✗
Enable Blob Soft Delete and set retention days to 365.
Why it's wrong here
Soft Delete prevents permanent deletion, not automated lifecycle moves.
✗
Move the blobs to Azure Files and set a file retention policy.
Why it's wrong here
Azure Files is not designed for this sensor data scenario.
Common exam traps
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.

Detailed technical explanation
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.
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.
