Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Grant the Azure Machine Learning workspace identity contributor access to the entire Key Vault resource.
Why it's wrong here
This violates the principle of least privilege.
- ✓
Enable a System-assigned Managed Identity on the endpoint and grant the identity the Key Vault Secrets User role.
Why this is correct
This allows the endpoint to authenticate to Key Vault without managing separate credentials.
- ✗
Assign the endpoint a Service Principal secret and store it in the environment variables of the scoring script.
Why it's wrong here
Using Service Principal secrets is less secure than using managed identities.
- ✗
Create a User-assigned Managed Identity and manually inject the OAuth token into the request header.
Why it's wrong here
Azure AI SDKs handle token acquisition automatically when using managed identities.
