問題文
In a Unity Catalog based setup, a registered model lives at a three-level name whose first level is the catalog. A new version is created there by the nightly training job. What does the enclosing catalog tell a reader about that version?
選択肢
- It tells them the model's lifecycle stage, because the catalog name is mapped to a stage value on the version, and reading the catalog name is enough to know the stage.
- It tells them that this version is the one currently being served to callers, because only versions that have been deployed are ever written into the production catalog, one catalog per deployment stage.
- It tells them nothing beyond storage location, because governance is configured per version rather than per catalog, so two versions in different catalogs are governed the same way once they exist.
- It tells them which environment the version belongs to and which governance rules apply, but not whether the version is currently serving traffic, since the catalog is where the rules attach.
