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.

• In your production database， you have multiple resource plan directives that refer to the consumer group DB_GRP. Which two statements are correct？（）

  A

  The parallel degree limit for DB_GRP will be the minimum of all the incoming values.

  B

  The parallel degree limit for DB_GRP will be the maximum of all the incoming values.

  C

  The maximum estimated execution time for DB_GRP would be the most nonrestrictive of all incoming values.

  D

  If a session switched from the DB_GRP consumer group to another consumer group because it exceeded the prescribed switch time， then that session would not execute if the active session pool for the new consumer group was full.

  E

  If a session switched from the DB_GRP consumer group to another consumer group because it exceeded the prescribed switch time， then that session would execute even if the active session pool for the new consumer group was full.
