Oracle OCP 1Z0 053 Q374(Recycle Bin)
374.Which of the following statements are true regarding the Recycle Bin? (Choose all that apply.)
A. The Recycle Bin is a physical storage area for dropped objects.
B. The Recycle Bin is a logical container for dropped objects.
C. The Recycle Bin stores the results of a Flashback Drop operation.
D. The objects in the Recycle Bin are stored in the tablespace in which they were created.
Answer: BD
C错误。Flashback Drop实际上只是将DROP掉的表又恢复为可见而已。只要表空间不紧张，DROP对象所占用的存储空间不会被占用。
The recycle bin is actually a data dictionary table containing information about dropped objects.
回收站本身是一个数据字典表，用于维护已删除对象的原始名称与各自系统生成名称之间的关系。
