A.SYS_GROUP gets 100% CPU resources at level 1.
B.FIN_GROUP1 gets 80% CPU resources at level 1.
C.FIN_GROUP1 gets 80% CPU resources at level 2.
D.PAY_GROUP1 gets 20% CPU resources at level 1.
E.PAY_GROUP1 gets 20% CPU resources at level 2.

D.The members of DEFAULT_CONSUMER_GROUP are restrained from accessing the system tables.
E.The members of this group can change their group without the database administrator’s intervention.

多项选择题View the Exhibit and examine the Resource Manager settings for the groups at different levels. Which two effects would be the result of this setting？（）

A.The members of LOW_GROUP would get more priority than those of OTHER_GROUPS.
B.The members of SYS_GROUP would get most of the CPU allocation at level 1.
C.The members of LOW_GROUP would get most of the CPU allocation because it has CPU allocation at two different levels.
D.The members of LOW_GROUP would get no CPU allocation at level 1 if the members of OTHER_GROUPS are using all the CPU at level 2.
E.The members of SYS_GROUP would get no CPU allocation at level 1 if the members of OTHER_GROUPS are using all the CPU at level 2.

单项选择题From the V$SESSION_LONGOPS view， you find that some of the database users have longrunning queries that consume a lot of CPU time. This causes performance problems for other users in the database， who have much shorter queries. You would like to make sure that the users with large queries do not use all the CPU time， but you still do not want to terminate them with an error message. Which method would you follow to achieve this？（）

A.set the CPU time per call in the users profile
B.set the CPU time per session in the users profiles
C.set the CPU levels for the users’ group using Resource Manager
D.set the TIMED_STATISTICS parameter to TRUE in the parameter file
