You need to ensure that applications will be able to use the authentication method with a non- expiring artifact to access the model. Solution: Create a Kubernetes online endpoint and set the value of its auth_mode parameter to aml_token. Deploy the model to the online endpoint. Does the solution meet the goal?

Options

• AYes
• BNo

Explanation

The aml_token authentication mode issues short-lived, expiring tokens and does not satisfy the requirement for a non-expiring authentication artifact.

Common mistakes.

• A. Answering Yes is incorrect because aml_token produces expiring credentials, directly contradicting the requirement for a non-expiring authentication method.
