Oracle 1z0-060 : Practice TestQuestion No : 1Your multitenant container (CDB) contains two pluggable databases (PDB), HR_PDB andACCOUNTS_PDB, both of which use the CDB tablespace. The temp file is calledtemp01.tmp.
A user issues a query on a table on one of the PDBs and receives the following error:
ERROR at line 1:
ORA-01565: error in identifying file ‘/u01/app/oracle/oradata/CDB1/temp01.tmp’
ORA-27037: unable to obtain file status
Identify two ways to rectify the error.
A. Add a new temp file to the temporary tablespace and drop the temp file that thatproduced the error.
B. Shut down the database instance, restore the temp01.tmp file from the backup, and thenrestart the database.
C. Take the temporary tablespace offline, recover the missing temp file by applying redologs, and then bring the temporary tablespace online.
D. Shutdown the database instance, restore and recover the temp file from the backup, andthen open the database with RESETLOGS.
E. Shut down the database instance and then restart the CDB and PDBs.
Answer: A,E
Explanation: * Because temp files cannot be backed up and because no redo is evergenerated for them, RMAN never restores or recovers temp files. RMAN does track thenames of temp files, but only so that it can automatically re-create them when needed.
* If you use RMAN in a Data Guard environment, then RMAN transparently convertsprimary control files to standby control files and vice versa. RMAN automatically updatesfile names for data files, online redo logs, standby redo logs, and temp files when you issueRESTORE and RECOVER.
Question No : 2Examine the following commands for redefining a table with Virtual Private Database (VPD)policies:

Oracle 1z0-060 : Practice Test
Which two statements are true about redefining the table?
A. All the triggers for the table are disabled without changing any of the column names orcolumn types in the table.
B. The primary key constraint on the EMPLOYEES table is disabled during redefinition. C. VPD policies are copied from the original table to the new table during onlineredefinition.
D. You must copy the VPD policies manually from the original table to the new table duringonline redefinition.
Answer: A,C
Explanation: The triggers cloned to the interim table are disabled until the redefinition iscompleted. Once the redefinition is complete, all cloned objects are renamed to the originalnames used by they objects they were cloned from.

Question No : 3Which two statements are true about the use of the procedures listed in thev$sysaux_occupants.move_procedure column?
A. The procedure may be used for some components to relocate component data to the

SYSAUX tablespace from its current tablespace.
B. The procedure may be used for some components to relocate component data from theSYSAUX tablespace to another tablespace.
C. All the components may be moved into SYSAUX tablespace.
D. All the components may be moved from the SYSAUX tablespace.

Question No : 4Which statement is true about Oracle Net Listener?
A. It acts as the listening endpoint for the Oracle database instance for all local and non-local user connections.
B. A single listener can service only one database instance and multiple remote clientconnections.
C. Service registration with the listener is performed by the process monitor (LREG)process of each database instance.
D. The listener.ora configuration file must be configured with one or more listening protocoladdresses to allow remote users to connect to a database instance. E. The listener.ora configuration file must be located in theORACLE_HOME/network/admin directly.
Answer: C
Question No : 5You are administering a database stored in Automatic Storage Management (ASM). Youuse RMAN to back up the database and the MD_BACKUP command to back up the ASMmetadata regularly. You lost an ASM disk group DG1 due to hardware failure.
In which three ways can you re-create the lost disk group and restore the data?
A. Use the MD_RESTORE command to restore metadata for an existing disk group bypassing the existing disk group name as an input parameter and use RMAN to restore the

data.
B. Use the MKDG command to restore the disk group with the same configuration as thebacked-up disk group and data on the disk group.
C. Use the MD_RESTORE command to restore the disk group with the changed disk groupspecification, failure group specification, name, and other attributes and use RMAN torestore the data.
D. Use the MKDG command to restore the disk group with the same configuration as thebacked-up disk group name and same set of disks and failure group configuration, and useRMAN to restore the data.
E. Use the MD_RESTORE command to restore both the metadata and data for the faileddisk group.
F. Use the MKDG command to add a new disk group DG1 with the same or differentspecifications for failure group and other attributes and use RMAN to restore the data.
Answer: C,D,F
Question No : 6Your multitenant container database, CDB1, is running in ARCHIVELOG mode and hastwo pluggable databases, HR_PDB and ACCOUNTS_PDB. An RMAN backup exists forthe database.
You issue the command to open ACCOUNTS_PDB and find that the USERDATA.DBFdata file for the default permanent tablespace USERDATA belonging to ACCOUNTS_PDBis corrupted.
What should you do before executing the commands to restore and recover the data file inACCOUNTS_PDB?
A. Place CDB1 in the mount stage and then the USERDATA tablespace offline inACCOUNTS_PDB.
B. Place CDB1 in the mount stage and issue the ALTER PLUGGABLE DATABASEaccounts_pdb CLOSE IMMEDIATE command.
C. Issue the ALTER PLUGGABLE DATABASE accounts_pdb RESTRICTED command. D. Take the USERDATA tablespace offline in ACCOUNTS_PDB.
Answer: D
Explanation: * You can take an online tablespace offline so that it is temporarily
unavailable for general use. The rest of the database remains open and available for usersto access data. Conversely, you can bring an offline tablespace online to make the schemaobjects within the tablespace available to database users. The database must be open to
