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.
正确答案：C
答案解析：RMAN的0级备份，相当于一个全量备份，但是RMAN全量备份不等于0级备份。1级备份必须基于0级备份实现，负责1级备份时，实际执行了0级备份。
