1Z0-053 争议题目解析695

考试科目：1Z0-053
题库版本：V13.02

题库中原题为：

695.Identify two options that Oracle recommends while configuring the backup and recovery environment
for your recovery catalog. (Choose two.)
A. configuring control file autobackup to be ON
B. backing up data filed only and not the archived redo log files
C. running the recovery catalog database in NOARCHIVELOG mode.
D. setting the retention policy to a REDUNDANCY value greater than 1
E. backing up the recovery catalog to the same disk as that of the target database
Answer:CD

争议点：
网上有人说选择AD，比如“标记为正确答案，不看answer版”题库。
比如Riveore的解析：http://blog.csdn.net/rlhua/article/details/17416541

Also, decide whether to operate the catalog database in ARCHIVELOG mode, which is recommended. C错

显然C不对，Oracle怎么会建议你的库运行NOARCHIVELOG模式？
而且从Riveore的解析中，也找到官档的原话如上，所以确定catalog数据库也是建议运行在归档模式下的。

初步结论：
题库答案错误，选择AD。
