（7）You have issued a SHUTDOWN ABORT command to bring down your database instance. Consider the steps that will be performed later when you open the database:

1: SGA is allocated.

2: Control file is read.

3: Redo log files are read.

4: Instance recovery is started.

5: Background processes are started.

6: Data files are checked for consistency.

7: Server parameter file or the initialization parameter file is read.

Which option has the correct order in which these steps occur?

A. 7, 1, 5, 2, 3, 6, 4

B. 1, 2, 3,7, 5, 6, 4

C. 7, 1, 4, 5, 2, 3, 6

D. 1, 7, 5, 4, 2, 3, 6

答案：（A）

解析：

先读服务器参数文件或初始化参数文件（7）->SGA内存被分配（1）->后台进程被启动（5）

到此已经确定了答案为A。
