AZ-204 Develop Azure compute solutions Practice Question
This AZ-204 practice question tests your understanding of develop azure compute solutions. 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.
A report export service in Azure App Service must safely access Key Vault secrets without connection strings in configuration. Which two steps are required?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Grant the identity permission to read the required secrets
Option C is correct because granting the managed identity permission to read secrets in Key Vault via Azure RBAC or access policies ensures that the App Service can authenticate without storing any secrets in configuration. This follows the principle of least privilege and eliminates the risk of credential leakage from app settings or connection strings.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Enable anonymous access on the vault
Why it's wrong here
Anonymous access is not allowed and would be insecure.
✗
Store the Key Vault access key in app settings
Why it's wrong here
Key Vault does not use access keys, and storing credentials defeats the purpose.
✓
Grant the identity permission to read the required secrets
Why this is correct
The identity must be authorized on Key Vault through RBAC or access policies.

✓
Enable a managed identity for the web app
Why this is correct
A managed identity gives the app an Azure AD identity without stored credentials.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often think storing the Key Vault URI or a reference in app settings is sufficient, but the question explicitly requires 'without connection strings in configuration,' so the correct path is to use managed identity plus granting permissions, not storing any key material.
Detailed technical explanation
How to think about this question
Under the hood, Azure App Service's managed identity obtains an Azure AD token from the instance metadata service (IMDS) endpoint at 169.254.169.254, which is then used to authenticate to Key Vault via OAuth 2.0. The Key Vault access policy or RBAC role assignment must include the 'Get' permission for secrets, and the identity's object ID (system-assigned or user-assigned) is used as the principal. A real-world scenario where this matters is when secrets must be rotated frequently; with managed identity, no code changes are needed because the identity automatically refreshes tokens.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
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.
