55. You have created a resource plan, PROD_DB_PLAN, with the followin
g consumer groups with the respective plan directives:
Consumer group SALES with CPU_P1as 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_P1as 0 and CPU_P2 as 100.
Which two statements are correct in this scenario? (Choose two.)
A.The maximum degree of parallelism for the members of the consumer g
roups is 4.
B.The CPU allocation will always be equal for the consumer groups MAR
KET and DEV.
C.The OTHERS consumer group would get 100% of the CPU if there are un
used level 1 CPU resources.
D.The SALES and MARKET consumer groups would get 100% of the CPU if t
here are unused level 2 CPU resources.
E.The maximum degree of parallelism for the members of the consumer g
roup SALES is 4 with no restriction for the remaining groups.
Answer: C,E
parallelism :平行 restriction :约束
对于b 选项:说明他们最多都占20%资源,但实际应用中不可能占用相等的资源
alway 就错了
