問題文

A provider wants to attach a masking policy to a column of a table that the app creates in a versioned schema. What does the framework allow?

選択肢

1. Masking policies are not supported in versioned schemas, so the policy and the object it protects have to live in a normal schema instead.
2. The policy can be attached only during an upgrade, because the assignment propagates to the incremental version at that point.
3. The policy can be attached if the app requests the APPLY MASKING POLICY privilege from the consumer, because the restriction is a matter of privileges.
4. The policy can be attached as long as it is defined in a normal schema, because the policy object and the protected object are independent.
