Selected Answer: A

The default authentication method when creating a managed online endpoint is a key, which does not expire unless explicitly regenerated. This satisfies the requirement of using a non-expiring artifact for authentication. Thus, the solution of creating a managed online endpoint with the default authentication settings and deploying the model to the online endpoint meets the goal.

No, the solution does not meet the goal. The default authentication settings for a managed online endpoint typically use Azure Active Directory (AAD) tokens, which do expire and are not non-expiring artifacts. To ensure that applications can use an authentication method with a non-expiring artifact, you should use a key-based authentication method, such as API keys, which do not expire unless explicitly regenerated.

Agree. When consuming an online endpoint from a client, you can use either a key or a token. Keys don't expire, tokens do. https://learn.microsoft.com/en-us/azure/machine-learning/how-to-authenticate-online-endpoint?view=azureml-api-2&tabs=python
