View the Exhibit and examine the parameter settings in your server-side parameter file (SPFILE).

When you tried to start the database instance, you received the following error:

Why did the instance fail to start?
A.Because the PGA_AGGREGATE_TARGET parameter is not set
B.Because the STATISTICS_LEVEL parameter is set to BASIC
C.Because MEMORY_TARGET and MEMORY_MAX_TARGET cannot be equal
D.Because both the SGA_TARGET and MEMORY_TARGET parameters are set.

官方答案是D，B的话也可以吧，STATISTICS_LEVEL设置为BASIC会禁用Automatic SGA Memory Management （ASMM）和自动内存管理
