Suggested Answer:

Box 1: Key Vault references in Application settings
Source Application Settings from Key Vault.
Key Vault references can be used as values for Application Settings, allowing you to keep secrets in Key Vault instead of the site config. Application Settings are securely encrypted at rest, but if you need secret management capabilities, they should go into Key Vault.
To use a Key Vault reference for an app setting, set the reference as the value of the setting. Your app can reference the secret through its key as normal. No code changes are required.

Box 2: Secrets: Get -
In order to read secrets from Key Vault, you need to have a vault created and give your app permission to access it.
1. Create a key vault by following the Key Vault quickstart.
2. Create a managed identity for your application.
3. Key Vault references will use the app's system assigned identity by default, but you can specify a user-assigned identity.
4. Create an access policy in Key Vault for the application identity you created earlier. Enable the "Get" secret permission on this policy.

The given answer is correct. Key Vault references in Application settings. All other option requires code changes. Get permission: The principle of least privilege means granting only the permissions necessary for the task. In this case, the application needs to retrieve secrets from Key Vault, so the Get permission is sufficient

Key Vault references in Application settings and secrets: List and Get is the best key vault integration method and key vault permissions for managed identity. per ChatGPT

ChatGPT apparently doesn't understand the concept of "least privilege". List gives the user access list all the keys in the vault. The user only needs access to the specific key, so you shouldn't include List privileges.

.Net core has appsettting.json only to store application settinggs or configuration data. Not sure what is application setting ?

Maybe app settings == App Configuration? Then it makes sense because you dont need to redeploy the app to change variables

Application settings are referred to as app settings here: https://learn.microsoft.com/en-us/azure/app-service/reference-app-settings?tabs=kudu%2Cdotnet. They are just the settings you can set for an app, directly in the Azure resource, without going into an actual appsettings.json file.
