考试科目:1Z0-053
题库版本:V13.02
题库中原题为:
577.What methods are available to recover lost control files? (Choose all that apply.)
A. Backup control file.
B. Emergency control file.
C. The create controlfile command.
D. The restore controlfile SQL*Plus command.
E. No backup is required. The database will re-create the control file when it is discovered to be lost.
Answer: CD
争议点:
网上有人说选择CD,即跟题库答案一致,
比如:
Riveore的解析:http://blog.csdn.net/rlhua/article/details/14849875
还有人说应该选择AC。因为D一定不对,理由很充分:SQL*Plus没用restore命令。
比如:
LuiseDalian的解析:http://blog.itpub.net/17013648/viewspace-1319579/
初步结论:
保留争议,个人偏向选择AC。
