Quick Answer
The correct RBAC role to assign is Key Vault Secrets User, as it provides the least-privilege permission needed for an app to read secret values using a managed identity. This role specifically grants the Microsoft.KeyVault/vaults/secrets/getSecret/action permission, which allows the managed identity to retrieve the actual secret content from Key Vault, unlike the Key Vault Reader role that only permits listing secret names without accessing their values. On the Microsoft Azure Developer Associate AZ-204 exam, this concept tests your understanding of Azure RBAC versus access policies, and a common trap is confusing Key Vault Reader with Secrets User—remember that Reader is for metadata only, not secret retrieval. The exam often presents scenarios where an app needs to fetch connection strings or API keys at runtime, and the managed identity must be assigned the correct role to avoid permission errors. A helpful memory tip: think "Secrets User gets the secret sauce," while Reader just sees the menu.
This AZ-204 practice question tests your understanding of connect to and consume azure services and third-party services. 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 app uses Azure Key Vault to store secrets. You need to grant the app access to read secrets using managed identity. Which RBAC role should you assign to the app's managed identity?
Key Vault Crypto Officer
Why wrong: Intended for key management, not secrets.
Key Vault Reader
Why wrong: Reader can list secrets but not read their values.
Key Vault Contributor
Why wrong: Contributor can manage secrets but is overly permissive.
Key Vault Secrets User
This role allows reading secret values.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Key Vault Secrets User
Key Vault Secrets User is the least-privilege role for reading secrets. Option A is wrong because Key Vault Reader only allows listing secrets, not reading values. Option C is wrong because Key Vault Contributor allows management. Option D is wrong because Key Vault Crypto Officer is for cryptographic keys.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Key Vault Crypto Officer
Why it's wrong here
Intended for key management, not secrets.
Key Vault Reader
Why it's wrong here
Reader can list secrets but not read their values.
Key Vault Contributor
Why it's wrong here
Contributor can manage secrets but is overly permissive.
Key Vault Secrets User
Why this is correct
This role allows reading secret values.
Related concept
Authentication checks who the user is.
Common exam traps
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Real-world example
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
What to study next
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related AZ-204 questions on access control and AAA configuration.
