A.The backups would be consistent.
B.The backups would be inconsistent.
C.The backups would be possible only if the database is running in ARCHIVELOG mode.

A,B：在數據庫打開的情況下備份，始終是不一致的。所以A錯B對。
C,D：只有在歸檔模式下，rman才能進行備份。所以C對，D錯。
E: 如果出現介質故障，則用restore備份中還原數據文件，用recover通過應用增量備份和重做日志文件中記錄的更改來恢復已還原文件到最近的事務提交點。E正確。
