单项选择题You issue the following code：    EXEC DBMS_RESOURCE_MANAGER_PRIVS.GRANT_SWITCH_CONSUMER_GROUP        （’SCOTT’ ’GRP1’， TRUE）；   What will be the result of executing the above code？（）

A. The switch privilege will be granted to the user， Scott， for changing the consumer group to GRP1.
B. The switch privilege will be granted to the user， Scott， for changing the consumer group from GRP1 to any other group.
C. The code will not execute successfully because there is no GRANT_SWITCH_CONSUMER_GROUP procedure in the DBMS_RESOURCE_MANAGER_PRIVS package.
D.The code will execute successfully but no privilege will be granted to the user， Scott.

单项选择题You are using the Database Resource Manager to manage database resources. You created a resource plan directive for the MANAGERS resource consumer group under the SALES_PLAN by using the following statement：   SQL>EXEC DBMS_RESOURCE_MANAGER.CREATE_PLAN_DIRECTIVE   （PLAN => ’SALES_PLAN’，   GROUP_OR_SUBPLAN => ’MANAGERS’，   CPU_P1 => 100， CPU_P2 =>0，   SWITCH_GROUP => ’CLERKS’，   SWITCH_TIME_IN_CALL => 600）；   A user， SCOTT， who is assigned to the MANAGERS group， starts a database session and executes a query on the database. What is the outcome if the query takes approximately 15 minutes to complete？（）

A. The query starts under the CLERKS group and the user， SCOTT， switches back to the MANAGERS group after the query completes.
B. The query starts under the MANAGERS group but terminates with an error when the execution time exceeds 10 minutes.
C. The query starts under the MANAGERS group and switches automatically to the CLERKS group when the execution time exceeds 10 minutes. The query does not switch back to the MANAGERS group after the query completes.
D. The query starts under the MANAGERS group， the user SCOTT switches automatically to the CLERKS group when the execution time exceeds 10 minutes， and then switches back to the MANAGERS group after the query completes.
