질문 # 204
Examine these RMAN commands:
RMAN> CONNECT TARGET "sbu@prod AS SYSBACKUP";
RMAN> CONNECT AUXILIARY "sbu@dup_db AS SYSBACKUP";
RMAN> DUPLICATE TARGET DATABASE TO dup_db FROM ACTIVE DATABASE
PASSWORD FILE SECTION SIZE 400M;
Which two statements are true about the DUPLICATE command?

A. It fails because connection to the AUXILIARY instance must be as SYSDBA.
B. It succeeds.
C. No catalogued backup of the TARGET is used to duplicate the database.
D. It fails because no parallel channels are allocated for the auxiliary database.
E. Itsucceeds only if the target database is greater than 400M.

정답：B,C

질문 # 205
You execute the following piece of code with appropriate privileges:
User SCOTT has been granted the CREATE SESSION privilege and the MGR role.
Which two statements are true when a session logged in as SCOTT queries the SAL column in the view and the table?

A. Data is redacted for EMP.SAL column only if the SCOTT session has the MGR role set.
B. Data is redacted for the EMP_V.SAL column only if the SCOTT session does not have the MGR role set.
C. Data is redacted for the EMP_V.SAL column only if the SCOTT session has the MGR role set.
D. Data is redacted for the EMP.SAL column only if the SCOTT session does not have the MGR role set.
E. Data is never redacted for the EMP_V.SAL column.

정답：D,E

설명：
Note:
* DBMS_REDACT.FULL completely redacts the column data.
* DBMS_REDACT.NONE applies no redaction on the column data. Use this function for development testing purposes. LOB columns are not supported.
* The DBMS_REDACT package provides an interface to Oracle Data Redaction, which enables you to mask (redact) data that is returned from queries issued by low-privileged users or an application.
* If you create a view chain (that is, a view based on another view), then the Data Redaction policy also applies throughout this view chain. The policies remain in effect all of the way up through this view chain, but if another policy is created for one of these views, then for the columns affected in the subsequent views, this new policy takes precedence.

질문 # 206

A. It applies patches in nonrolling mode by default.
B. It must be invoked by a user with root user privileges.
C. Users must always input patch plans to opatchauto.
D. It Is used to apply interim patches to Oracle Grid Infrastructure and Oracle Database home combinations.
E. It performs a shutdown and then a restart of all processes in both Oracle Grid Infrastructure and Oracle Database home during the patching process.
F. It requires the Oracle Grid Infrastructure and Oracle Database instances to be shut down before being invoked.
G. Patchsets are applied via opatchauto.

정답：A,F,G

질문 # 207

질문 # 208
While backing up to the Oracle Fast Recovery Area (FRA), you determined the backup istaking too long and suspect a performance bottleneck. Which three are true about diagnosing and tuning these problems? (Choose three.)

A. If an RMAN BACKUP VALIDATE command takesroughly the same time as an actual backup, then both read and write I/O are likely bottlenecks.
B. If an RMAN BACKUP VALIDATE command takes noticeably lessthan an actual backup, then write I/O is a likely bottleneck.
C. Setting DBWR_IO_SLAVES to a non zero value can improve backup performance when using synchronous I/O.
D. If an RMAN BACKUP VALIDATE command takesroughly the same time as an actual backup, then read I/O is a likely bottleneck.
E. Data files with a high value in V$BACKUP_SYNC_IO.DISCRETE_BYTES_PER_SECOND are a potential performance bottleneck when synchronous I/O is used.
F. Data files with a high value in V$BACKUP_ASYNC_IO.SHORT_WAITS are a potential performance bottleneck when asynchronous I/O is used.
G. Setting DBWR_IO_SLAVES to a non zero value can improve backup performance when using asynchronous I/O/

정답：B,C,E
