Q3. Your multitenant container database (CDB) cdb1 that is running in archivelog mode contains two pluggable databases (PDBs), pdb2_1 and pdb2_2. RMAN is connected to the target database pdb2_1.
Examine the command executed to back up pdb2_1:
RMAN> BACKUP DATABASE PLUS ARCHIVELOG;
Which statement is true about the execution of this command?
A. It fails because archive log files cannot be backed up using a connection to a PDB.
B. It succeeds but only the data files belonging to the pdb2_i pluggable database are backed up.
C. It succeeds andall data files belonging to PD32_i are backed up along with the archive log files.
D. It fails because the pluggable clause is missing.
Answer: C
Q4. You are administering a database that supports a data warehousing workload and is running in noarchivelog mode. You use RMAN to perform a level 0 backup on Sundays and level 1 incremental backups on allthe other days of the week.
One of the data files is corrupted and the current online redo log file is lost because of a media failure.
Which action must you take for recovery?
A. Restore the data file, recover it by using the recover datafilenoredo command, and use the resetlogs option to open the database.
B. Restore the control file and all the data files, recover them by using the recover database noredo command, and use the resetlogs option to open the database.
C. Restore all the data files, recoverthem by using the recover database command, and open the database.
D. Restore all the data files, recover them by using the recover database noredo command, and use the resetlogs option to open the database.

Answer: B,C,E
Q8. You create two Resource Manager plans, one for night time workloads, the other for day time.
How would you make the plans switch automatically?
A. Use job classes.
B. Use scheduler windows.
C. Use the mapping rule for the consumer groups.

Answer: B
Q9. After implementing full Oracle Data Redaction, you change the default value for the number
data type as follows:
SQL> SELECT NUMBER_VALUE FROM REDACTION_VALUES_FOR_TYPE_FULL; NUMBER_VALUE
0
SQL> EXEC DBMS_REDACT.UPDATE_FULL_REDACTI0N_VALUES(-1)
PL/SQL procedure successfully completed.
SQL> select number_value from redaction_values_for_type_full;
NUMBER VALUE
-1
After changing the value, you notice that FULL redaction continues to redact numeric data with a zero.
What must you do to activate the new default value for numeric full redaction?
A. Re-enable redaction policies that use FULL data redaction.
B. Re-create redaction policies that use FULL data redaction.
C. Re-connect the sessions that access objects with redaction policies defined on them.
D. Flush the shared pool.
E. Restart the database instance.
Answer: E
Explanation: About Altering the Default Full Data Redaction Value You can alter the default displayed values for full Data Redaction polices. By default, 0 is the redacted value when Oracle Database performs full redaction (DBMS_REDACT.FULL) on a column of the NUMBER data type. If you want to change it to another value (for example, 7), then you can run the DBMS_REDACT.UPDATE_FULL_REDACTION_VALUES procedure to modify this value. The modification applies to all of the Data Redaction policies in the current database instance. After you modify a value, you must restart the database for it to take effect.
Q10. Examine the command:
SQL>RECOVER DATABASE USING BACKUP CONTROLFILE UNTIL CANCEL;
In which two scenarios is this command required?
A. The current online redo log file is missing.
B. A data file belonging to a noncritical tablespace is missing.
C. All the control files are missing.
D. The database backup is older than the control file backup.
E. All the data files are missing.
Answer: C,D

optimizer_features_enablestring12.1.0.1
Which three statements are true about the process of automatic optimization by using statistics feedback?
A. The optimizer automatically changes a plan during subsequent execution of a SQL statement if there is a huge difference in optimizer estimates and execution statistics.
B. The optimizer can re optimize a query only once using cardinality feedback.
C. The optimizer enables monitoring for cardinality feedback after the first execution of a query.
D. The optimizer doesnot monitor cardinality feedback if dynamic sampling and multicolumn statistics are enabled.
E. After the optimizer identifies a query as a re-optimization candidate, statistics collected by the collectors are submitted to the optimizer.
Answer: A,C,D
Explanation: C: During the first execution of a SQL statement, an execution plan is generated as usual.
D: if multi-column statistics are not present for the relevant combination of columns, the
optimizer can fall back on cardinality feedback.
(not B)* Cardinality feedback. This feature, enabled by default in 11.2, is intended to
improve plans for repeated executions.
optimizer_dynamic_sampling optimizer_features_enable
Dynamic sampling or multi-column statistics allow the optimizer to more accurately estimate selectivity of conjunctive predicates.
Note:
* OPTIMIZER_DYNAMIC_SAMPLING controls the level of dynamic sampling performed by the optimizer. Range of values. 0 to 10
Cardinality feedback was introduced in Oracle Database 11gR2. The purpose of this feature is toautomatically improve plans for queries that are executed repeatedly, for which the optimizer does not estimate cardinalities in the plan properly. The optimizer may misestimate cardinalities for a variety of reasons, such as missing or inaccurate statistics, or complex predicates. Whatever the reason for the misestimate, cardinality feedback may be able to help.

Q14. The CATDBI2c database contains an Oracle Database 12c catalog schema owned by the rc12c user.
The CATDB11 database contains an Oracle Database l1g catalog schema owned by the RCII user.
A database with DBID=1423241 is registered in the CATDB11 catalog. Both the recovery catalog databases are open.
In the CATDB12c database, you execute the commands:
Srman
RMAN> CONNECT CATALOG rc12c/pass12c8catdbI2c
RMAN> IMPOST CATALOG rc1l/pwdcatl19catdbl1 DBID=I423241;
What is the outcome of the import?
A. It fails because the target database and recovery catalog database are of different versions.
B. It succeeds and all global scripts in the sc:: catalog that have the same name as existing global scripts in the RC12C catalog are automatically renamed.
C. It succeeds but the database is not automatically registered in the Rc12c catalog.
D. It fails because RMAN is not connected to the target database with DBID=1423241.
Answer: B
