Which statement is true about sharing inheritance in datasets?

The accurate statement regarding sharing inheritance in datasets is that a security predicate must be defined for sharing. This is important because sharing inheritance controls how data access is shared among users based on their respective roles and permissions. Without a security predicate, there wouldn’t be a mechanism to enforce access controls, which would compromise data security. The predicate acts as a filter to determine which records are visible to each user according to their security settings.

The other options touch on aspects of dataset sharing but do not accurately capture the necessity of security predicates. For instance, while it might seem that a dataset could use sharing without security predicates, this would not be practical in enforcing access control. Similarly, the assertion that sharing inheritance is always enabled does not reflect that it can be dependent on whether security predicates are applied. The claim about custom objects not requiring security predicates misunderstands the principle of data access control, which relies on defined rules to secure visibility and sharing effectively.
