Your multitenant container (CDB) contains two pluggable databases (PDB), HR_PDB and
ACCOUNTS_PDB, both of which use the CDB tablespace. The temp file is called
temp01.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 that
produced the error.
B. Shut down the database instance, restore the temp01.tmp file from the backup, and then
restart the database.
C. Take the temporary tablespace offline, recover the missing temp file by applying redo
logs, and then bring the temporary tablespace online.
D. Shutdown the database instance, restore and recover the temp file from the backup, and
then 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 ever
generated for them, RMAN never restores or recovers temp files. RMAN does track the
names 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 converts
primary control files to standby control files and vice versa. RMAN automatically updates
file names for data files, online redo logs, standby redo logs, and temp files when you issue
RESTORE and RECOVER.

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 or
column 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 online
redefinition.
D. You must copy the VPD policies manually from the original table to the new table during
online redefinition.
Answer: A,C
Explanation: The triggers cloned to the interim table are disabled until the redefinition is
completed. Once the redefinition is complete, all cloned objects are renamed to the original
names used by they objects they were cloned from.

SYSAUX tablespace from its current tablespace.
B. The procedure may be used for some components to relocate component data from the
SYSAUX 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.

Which 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 client
connections.
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 protocol
addresses to allow remote users to connect to a database instance.
E. The listener.ora configuration file must be located in the
ORACLE_HOME/network/admin directly.
Answer: C
You are administering a database stored in Automatic Storage Management (ASM). You
use RMAN to back up the database and the MD_BACKUP command to back up the ASM
metadata 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 by
passing 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 the
backed-up disk group and data on the disk group.
C. Use the MD_RESTORE command to restore the disk group with the changed disk group
specification, failure group specification, name, and other attributes and use RMAN to
restore the data.
D. Use the MKDG command to restore the disk group with the same configuration as the
backed-up disk group name and same set of disks and failure group configuration, and use
RMAN to restore the data.
E. Use the MD_RESTORE command to restore both the metadata and data for the failed
disk group.
F. Use the MKDG command to add a new disk group DG1 with the same or different
specifications for failure group and other attributes and use RMAN to restore the data.
Answer: C,D,F
Your multitenant container database, CDB1, is running in ARCHIVELOG mode and has
two pluggable databases, HR_PDB and ACCOUNTS_PDB. An RMAN backup exists for
the database.
You issue the command to open ACCOUNTS_PDB and find that the USERDATA.DBF
data file for the default permanent tablespace USERDATA belonging to ACCOUNTS_PDB
is corrupted.
What should you do before executing the commands to restore and recover the data file in
ACCOUNTS_PDB?
A. Place CDB1 in the mount stage and then the USERDATA tablespace offline in
ACCOUNTS_PDB.
B. Place CDB1 in the mount stage and issue the ALTER PLUGGABLE DATABASE
accounts_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 users
to access data. Conversely, you can bring an offline tablespace online to make the schema
objects within the tablespace available to database users. The database must be open to
