1.Examine the parameter setting in your database:Which statement is correct about the database?()A. Automatic memory management is disabled because PGA_AGGREGATE_TARGET and SGA_TARGET are not setB. The instance is started but the database will not be opened until PGA_AGGREGATE_TARGET and SGA_TARGET are setC. The database is opened but users cannot perform transactions until PGA_AGGREGATE_TARGET and SGA_TARGET are setD. Automatic memory management is enabled and, as per policy, 60% of the memory for System Global Area (SGA) and 40% of the memory for Program Global Area (PGA) will be distributed at startup

2.You specify a nonzero value for the MEMORY_TARGET initialization parameter, but do not set the PGA_AGGREGATE_TARGET or the SGA_TARGET parameters. You restart your database instance.Which statement about the result is true?（）A. The database instance starts, and Oracle sets the default value of SGA_TARGET to the same value as SGA_MAX_SIZEB. The database instance starts, and Oracle automatically tunes memory and allocates 60 percent to the SGA and 40 percent to the PGAC. The database instance starts, but Automatic Memory Management is disabledD. The database instance will not start because you did not specify the PGA_AGGREGATE_TARGET or SGA_TARGET parameter

4.You set the following parameters in the parameter file and restarted the database:Which two statements are true regarding these parameters after the database instance is restarted?()A. The MEMORY_MAX_TARGET parameter is automatically set to 500 MBB. The value of the MEMORY_MAX_TARGET parameter remains zero till it is changed manuallyC. The PGA_AGGREGATE_TARGET and SGA_TARGET parameters are automatically set to zeroD. The lower bounds of PGA_AGGREGATE_TARGET and SGA_TARGET parameters are set to 90 MB and 270 MB, respectively
