D. For centralized, global operations that should be fired for the triggering statement, regardless of which user or application issues the statement.
3. Local procedure A calls remote procedure B. Procedure B was compiled at 8 A.M. Procedure
A was modified and recompiled at 9 A.M. Remote procedure B was later modified and
recompiled at 11 A.M. The dependency mode is set to TI MESTAMP. What happens when
procedure A is invoked at 1 P.M?
A. There is no affect on procedure A and it runs successfully.

B. The trigger fails because it needs to be a row level AFTER UPDATE trigger.
C. The trigger fails because a SELECT statement on the table being updated is not allowed.
D. The trigger fails because you cannot use the minimum and maximum functions in a BEFORE UPDATE trigger.
