Quick Answer
The answer is Azure App Configuration and Azure Key Vault. Azure App Configuration is a purpose-built managed service for storing and managing application configuration settings and feature flags, while Azure Key Vault is designed to securely store secrets such as connection strings, API keys, and certificates that are often part of an application’s configuration. On the Microsoft Azure Developer Associate AZ-204 exam, this question tests your ability to distinguish between dedicated configuration services and general storage options; a common trap is choosing Blob Storage or Cosmos DB because they can technically hold config files, but they lack the managed, centralized, and secure access features required for enterprise configuration management. Remember the memory tip: “Config and Secrets” — App Configuration for non-sensitive settings, Key Vault for sensitive secrets, and never use a database or blob container for primary configuration storage.
This AZ-204 practice question tests your understanding of connect to and consume azure services and third-party services. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Which TWO Azure services can be used to store application configuration settings?
Azure App Configuration
Azure App Configuration is a managed service for configuration settings.
Azure Queue Storage
Why wrong: Queue Storage is for messaging.
Azure Blob Storage
Why wrong: Blob Storage can store config files but is not a managed configuration service.
Azure Cosmos DB
Why wrong: Cosmos DB is a database, not a configuration store.
Azure Key Vault
Key Vault can store secrets that are part of configuration.
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 App Configuration
Options B and C are correct. Azure App Configuration is purpose-built for configuration. Azure Key Vault can store secrets that are part of configuration. Option A (Cosmos DB) is a database; Option D (Blob Storage) can store config files but is not a managed configuration service; Option E (Queue Storage) is for messages.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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 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.
