多项选择题

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.

多项选择题You have created a resource plan， PROD_DB_PLAN， with the following consumer groups with the respective plan directives： Consumer group SALES with CPU_P1 as 60 and DEGREE_OF_PARALLELISM as 4. Consumer group MARKET with CPU_P1 as 20. Consumer group DEV with CPU_P1 as 20. Consumer group OTHERS with CPU_P1 as 0 and CPU_P2 as 100. Which two statements are correct in this scenario？（）

A.The maximum degree of parallelism for the members of the consumer groups is 4.
B.The CPU allocation will always be equal for the consumer groups MARKET and DEV.
C.The OTHERS consumer group would get 100% of the CPU if there are unused level 1 CPU resources.
D.The SALES and MARKET consumer groups would get 100% of the CPU if there are unused level 2 CPU resources.
E.The maximum degree of parallelism for the members of the consumer group SALES is 4 with no restriction for the remaining groups.

单项选择题You have created a resource plan， PROD_DB_PLAN， that uses the RATIO policy. The following consumer groups and their respective plan directives have been assigned to this resource plan： Consumer group HIGH_CG with CPU_P1 as 10. Consumer group MEDIUM_CG with CPU_P1 as 5. Consumer group LOW_CG with CPU_P1 as 2. Consumer group OTHER_GROUPS with CPU_P1 as 1. Which statement is correct in this scenario？（）

A.The plan PROD_DB_PLAN can have subplans.
B.The members of the HIGH_CG consumer group would get 10% of the CPU.
C.The CPU allocation for the consumer groups would be based on the ratio defined for the CPU_P1.
D.The CPU allocation would be equal between the HIGH_CG and MEDIUM_CG consumer groups if there are no sessions existing for the LOW_CG and OTHER_GROUPS consumer groups.

B.grant SYSOPER to the user
C.grant the RESOURCE role to the user
D.use the GRANT command to grant the ADMINISTER_RESOURCE_MANAGER privilege to the user
E.grant the ADMINISTER_RESOURCE_MANAGER privilege to the user by using the DBMS_RESOURCE_MANAGER_PRIVS package
