Question: 1
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. (Choose two.)
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. Shut down 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
* 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.
Question: 2
Which two statements are true about the use of the procedures listed in the
v$sysaux_occupants.move_procedure column? (Choose two.)
A. The procedures may be used for some components to relocate component data to the SYSAUX
tablespace from its current tablespace.
B. The procedures 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 the SYSAUX tablespace.
D. All the components may be moved from the SYSAUX tablespace.
Answer: A,B

Question: 3
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 listener registration process (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 directory.
Answer: C
Question: 4
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? (Choose three.)
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
Question: 5
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 take 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 OPEN RESTRICTED command.
D. Take the USERDATA tablespace offline in ACCOUNTS_PDB.
Answer: D
* 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 alter the availability of a tablespace.
