Quick Answer
The answer is Azure Key Vault, Azure App Configuration, and Azure Managed HSM. These three Azure services are specifically designed to securely store and retrieve secrets, connection strings, and API keys for cloud-native applications, leveraging hardware security modules and encryption at rest and in transit. Azure Key Vault acts as a centralized vault for secrets and certificates, Azure App Configuration provides managed configuration stores with built-in encryption for app settings and feature flags, and Azure Managed HSM offers a fully managed, single-tenant hardware security module for the highest level of key control. On the AZ-204 exam, this concept tests your understanding of secure configuration management versus general-purpose storage; a common trap is choosing Azure Cosmos DB or Blob Storage, which are not secret management services. Remember the mnemonic “KAM” (Key Vault, App Configuration, Managed HSM) to recall the three secure storage services for secrets.
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 THREE Azure services can be used to securely store and retrieve secrets, connection strings, and API keys for a cloud-native application?
Azure Blob Storage
Why wrong: Incorrect: object storage, not for secrets.
Azure App Configuration
Correct: stores configuration and feature flags, can reference Key Vault.
Azure Managed HSM
Correct: hardware security module for key storage.
Azure Cosmos DB
Why wrong: Incorrect: a NoSQL database, not for secret management.
Azure Key Vault
Correct: stores secrets, keys, and certificates.
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
Azure Key Vault, Azure App Configuration, and Azure Managed HSM are designed to store secrets and configuration securely. Azure Cosmos DB and Azure Blob Storage are not primarily for secret management.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Azure Blob Storage
Why it's wrong here
Incorrect: object storage, not for secrets.
Azure App Configuration
Why this is correct
Correct: stores configuration and feature flags, can reference Key Vault.
Related concept
Static NAT maps one inside address to one outside address.
Azure Managed HSM
Why this is correct
Correct: hardware security module for key storage.
Related concept
Static NAT maps one inside address to one outside address.
Azure Cosmos DB
Why it's wrong here
Incorrect: a NoSQL database, not for secret management.
Azure Key Vault
Why this is correct
Correct: stores secrets, keys, and certificates.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related AZ-204 NAT questions on configuration and troubleshooting.

Same concept, more angles
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Which TWO Azure services can be used to store and manage secrets, such as API keys and connection strings? (Choose 2)
easyWhy A: Option B is correct because Azure Key Vault is designed for secret storage. Option D is correct because Azure Managed Identity helps manage credentials without storing secrets. Option A is incorrect because Azure App Configuration is for configuration settings, not secrets. Option C is incorrect because Azure Storage is for data storage. Option E is incorrect because Azure SQL Database is for relational data.
Variation 2. Which TWO Azure services can be used to securely store and retrieve secrets, such as API keys and connection strings, for use in cloud applications?
easyWhy B: A and D are correct. Azure Key Vault is designed for secrets management. Azure App Configuration can store Key Vault references, effectively storing secrets securely. Option B is wrong because Azure Blob Storage is not designed for secrets; it stores blobs. Option C is wrong because Azure Cosmos DB is a NoSQL database. Option E is wrong because Azure SQL Database is a relational database.
