第1题：

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_SIZE

B. The database instance starts, and Oracle automatically tunes memory and allocates 60 percent to the SGA and 40 percent to the PGA

C. The database instance starts, but Automatic Memory Management is disabled

D. The database instance will not start because you did not specify the PGA_AGGREGATE_TARGET or SGA_TARGET parameter


参考答案：B

第5题：

Which statement about Automatic Memory Management with Oracle 11g is true？（）  

  • A、 You cannot specify MEMORY_TARGET if you explicitly specify SGA_TARGET or  PGA_AGGREGATE_ TARGET values that are greater than zero in your parameter file.
  • B、 Oracle can reallocate memory between the SGA and PGA automatically as needed.
  • C、 To use Automatic Memory Management， you must explicitly set both the MEMORY_TARGET and MEMORY_MAX_TARGET parameters in your parameter file.
  • D、 You can set the MEMORY_TARGET parameter to a maximum value of the current SGA size plus the current PGA size.

正确答案:B

第6题：

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_SIZE
  • B、 The database instance starts，and Oracle automatically tunes memory and allocates 60 percent to the  SGA and 40 percent to the PGA
  • C、 The database instance starts，but Automatic Memory Management is disabled
