Database questions in AZ-900 are about choosing the right managed data platform for workload shape, not low-level SQL syntax. The exam tests relational versus NoSQL fit and management expectations.
You will often compare Azure SQL options against Cosmos DB or managed open-source engines. The correct answer usually follows consistency model, schema flexibility, and global distribution needs.
High-value answers align database selection with operational simplicity, scaling model, and app architecture patterns.
Managed database choices AZ-900 often asks you to separate
| Decision Point | Option A | Option B | Exam Takeaway |
|---|---|---|---|
| Data model requirement | Azure SQL Database/Managed Instance for relational workloads | Cosmos DB for globally distributed NoSQL workloads | If schema is relational and SQL semantics are required, Azure SQL options are usually expected. |
| Global scale and low-latency access | Cosmos DB multi-region design capabilities | Single-region relational pattern for globally distributed app demand | Global low-latency multi-region requirements often point toward Cosmos DB features. |
| Operational responsibility | Fully managed PaaS databases with built-in patching and backups | Self-managed database on virtual machines for every scenario | When minimizing admin overhead is explicit, managed database services are usually preferred. |
Selecting a data platform for a modern SaaS application
A team needs transactional billing data plus globally distributed user activity records with different access characteristics.
- Separate relational and document-style workload requirements.
- Map latency and distribution goals to service capabilities.
- Choose managed offerings that reduce backup and patching burden.
- Validate security and access control integration requirements.
Common Exam Trap: Using one database technology for every data pattern without evaluating access model differences is a recurring exam pitfall.

Key Databases Concepts for AZ-900
AZ-900 Databases Exam Tips
Azure Database Services questions in AZ-900 are typically scenario-based. Focus on Azure fundamentals, service purpose recognition, and cost/governance basics. Priority concepts: azure sql, cosmos db, mysql, postgresql, sql managed instance, database.
What AZ-900 Expects
- Anchor your answer in pick concise foundational answers and avoid advanced implementation details.
- Databases scenarios for AZ-900 are frequently mapped to Domain 2 (35-40%), so read the objective carefully before picking controls or architecture.
- Expect multi-topic scenarios where Databases interacts with identity, networking, governance, or monitoring patterns rather than appearing as an isolated question.
- When two options are both technically valid, prefer the choice that best aligns with the exam's operational scope (Fundamentals) and vendor best practices.
High-Value Databases Concepts
- Know the core Databases building blocks cold: azure sql, cosmos db, mysql, postgresql.
- Review the edge-case features and limits for sql managed instance, database; these details are commonly used to differentiate answer choices.
- Practice service-integration reasoning: how Databases pairs with Storage, Compute in real deployment patterns.
- For AZ-900, explain why the chosen Databases design meets reliability, security, and cost expectations better than the alternatives.
Common AZ-900 Traps
- Watch for mixing IaaS, PaaS, and SaaS responsibilities.
- Questions in Describe Azure Architecture and Services often include distractors that look correct for Databases but violate least-privilege, compliance, or availability requirements.
- Avoid picking options purely by feature name; validate data path, failure handling, and governance impact before answering.
- If the prompt hints at automation or repeatability, eliminate manual-only operational answers first.
Fast Review Checklist
- Can you compare at least two Databases implementation paths and justify which one best fits the scenario?
- Can you map the chosen answer back to Describe Azure Architecture and Services (35-40%) outcomes for AZ-900?
- Can you explain security and access boundaries for Databases without relying on default-open assumptions?
- Can you describe how Databases integrates with Storage and Compute during failure, scaling, and monitoring events?
