問題文
A hosting team wants the space that one pluggable database is able to take to be bounded, and asks how that bound is expressed and what happens when it is left out. Which statement about that is correct?
選択肢
- The bound is written in an optional clause of the creating statement and it covers the space that every tablespace of that database takes upon its own, so leaving the clause out makes the database take the bound that the root has been given.
- The bound is written in an optional clause of the creating statement and it covers the space that all the tablespaces of that database take together, so leaving the clause out is the same as asking for no bound at all.
- The bound is written in an optional clause of the creating statement and it covers the space that each tablespace of that database takes on its own, so leaving the clause out is the same as asking for no bound at all.
- The bound is written in a required clause of the creating statement and it covers the space that all the tablespaces of that database take together, so a statement that leaves the clause out is turned away by the database.
