You set the undo pool resource plan directive for the consumer group named DSS_USERS that is assigned to the DAY_SHIFT plan. The database users, SCOTT and BLAKE, belong to the DSS_USERS resource group. The user, SCOTT, initiates a database session and executes a batch operation that inserts millions of rows into the HISTORY table. Which two options are true if the total undo space allocated to the DSS_USERS group exceeds the value specified in the undo pool resource plan directive?()
A

The batch operation started by the user, SCOTT, terminates with an error.

B

The batch operation started by the user, SCOTT, hangs and you are required to increase the undo pool resource plan directive.

C

The batch operation started by the user, SCOTT, runs uninterrupted because the database uses the SYSTEM tablespace for the undo operation.

D

The user, BLAKE, cannot start a transaction that uses any DML operations until you increase the value of the undo pool resource plan directive.

E

The user BLAKE can start a transaction that uses any DML operations after the batch operation started by the user, SCOTT, terminates with an error.
