This DP-900 practice question tests your understanding of identify considerations for 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.
Your team is designing a database for a financial application that requires ACID transactions. You are considering Azure Cosmos DB and Azure SQL Database. Which service should you choose?
Azure SQL Database
Provides full ACID transactions.
Azure Table Storage
Why wrong: No ACID support.
Azure Cosmos DB
Why wrong: Limited ACID support.
Azure Database for MySQL
Why wrong: Not the best choice for the scenario.
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 SQL Database
Option B is correct because Azure SQL Database provides full ACID transactions. Option A is wrong because Azure Cosmos DB provides limited transactional support. Option C is wrong because Azure Database for MySQL provides ACID but the question asks between Cosmos DB and SQL Database. Option D is wrong because Azure Table Storage does not support ACID.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

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.
Trap categories for this question
Scenario analysis trap
Not the best choice for the scenario.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
