The ORCL database has CONTROL FILE AUTOBACKUP and BACKUP OPTIMIZATION enabled. 

USER1.EMP is a table in tablespace TBS1

There are no existing backups of the database.

Examine these commands:

$ rman target /

RMAN> BACKUP DATABASE

RMAN>exit

$sqlplus / as sysdba

SQL>UPDATE USER1.EMP set SAL=5000 WHERE ENO=10;

       1 row updated.

SQL>COMMIT;

      Commit complete.

SQL>exit

$rman target /

RMAN> CONFIGURE EXCLUDE FOR TABLESPACE tbs1;

RMAN>BACKUP INCREMENTAL LEVEL 1 DATABASE;

What is the outcome?

A.It takes a level 0 incremental backup of ORCL with TBS1.

B.It takes a level 1 incremental backup of ORCL without TBS1.

C.It takes a level 0 incremental backup of ORCL without TBS1.

D.It takes a level 1 incremental backup of ORCL with TBS1.

正確答案：C

答案解析：RMAN的0級備份，相當於一個全量備份，但是RMAN全量備份不等於0級備份。1級備份必須基於0級備份實現，負責1級備份時，實際執行了0級備份。
