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.
You are designing a solution to store large binary files (videos) for a media company. The solution must support tiered storage to optimize costs based on access frequency. Which Azure storage option should you use?
Azure Cosmos DB
Why wrong: Azure Cosmos DB is a database, not for binary file storage.
Azure Files
Why wrong: Azure Files is for SMB file shares, not tiered storage.
Azure Blob Storage
Azure Blob Storage supports access tiers for cost optimization.
Azure Disk Storage
Why wrong: Azure Disk Storage is for VM disks, not object storage.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Azure Blob Storage
Option C is correct because Azure Blob Storage supports access tiers (Hot, Cool, Archive) for cost optimization. Option A is wrong because Azure Files is for file shares, not tiered storage for videos. Option B is wrong because Azure Disk Storage is for VM disks, not object storage. Option D is wrong because Azure Cosmos DB is a database, not for storing large binary files.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Azure Cosmos DB
Why it's wrong here
Azure Cosmos DB is a database, not for binary file storage.
Azure Files
Why it's wrong here
Azure Files is for SMB file shares, not tiered storage.
Azure Blob Storage
Why this is correct
Azure Blob Storage supports access tiers for cost optimization.
Related concept
Read the scenario before looking for a memorised answer.
Azure Disk Storage
Why it's wrong here
Azure Disk Storage is for VM disks, not object storage.
Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
