問題文
A serving system must be repointed from one model version to another without changing the deployment configuration. Which reference form makes that possible?
選択肢
- A reference naming the model and an alias, so reassigning the alias switches the traffic without touching the deployment.
- The identifier of the run that produced the model, so pointing the serving system at another run switches the version and leaves the rest alone.
- A path to the artifact file in object storage, so overwriting the file at that path moves the traffic across to the new version.
- A reference naming the model and the version number, because the registry resolves the number to the latest compatible artifact at load time and therefore picks up a newer version automatically once one is registered.
