Question 1 of 175

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.)

Add a new temp file to the temporary tablespace and drop the temp file that that produced the error.

Shut down the database instance, restore the temp01.tmp file from the backup, and then restart the database.

Take the temporary tablespace offline, recover the missing temp file by applying redo logs, and then bring the temporary tablespace online.

Shut down the database instance, restore and recover the temp file from the backup, and then open the database with RESETLOGS.

Shut down the database instance and then restart the CDB and PDBs.

Correct Answer: A, E

Question 2 of 175

Examine the following commands for redefining a table with Virtual Private Database (VPD) policies:
Exam 1z0-060: Question 2 - Image 1

Which two statements are true about redefining the table? (Choose two.)

All the triggers for the table are disabled without changing any of the column names or column types in the table.

The primary key constraint on the EMPLOYEES table is disabled during redefinition.

VPD policies are copied from the original table to the new table during online redefinition.

You must copy the VPD policies manually from the original table to the new table during online redefinition.

Correct Answer: A, C

Question 3 of 175

Which statement is true about Oracle Net Listener?

It acts as the listening endpoint for the Oracle database instance for all local and non-local user connections.

A single listener can service only one database instance and multiple remote client connections.

Service registration with the listener is performed by the listener registration process (LREG) process of each database instance.

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.

The listener.ora configuration file must be located in the ORACLE_HOME/network/admin directory.

Correct Answer: C

Question 4 of 175

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?

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.

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.

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.

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.

Use the MD_RESTORE command to restore both the metadata and data for the failed disk group.

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

Correct Answer: C, D, F

There are three ways to re-create a lost ASM disk group and restore the data: First, using the MD_RESTORE command with modified specifications for the restored disk group, followed by using RMAN to restore the data ensures flexibility in configuration while recovering the disk group (C). Second, using the MKDG command with the exact same configuration as the backed-up disk group and subsequently using RMAN to restore the data ensures that the disk group is re-created exactly as it was (D). Third, using the MKDG command to create a new disk group with the same or different specifications, then using RMAN to restore the data, provides an option to re-create a disk group with potentially improved configurations (F).

Question 5 of 175

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 is corrupted.

ACCOUNTS_PDB -
What should you do before executing the commands to restore and recover the data file in ACCOUNTS_PDB?

Place CDB1 in the mount stage and then take the USERDATA tablespace offline in ACCOUNTS_PDB.

Place CDB1 in the mount stage and issue the ALTER PLUGGABLE DATABASE accounts_pdb CLOSE IMMEDIATE command.

Issue the ALTER PLUGGABLE DATABASE accounts_pdb OPEN RESTRICTED command.

Take the USERDATA tablespace offline in ACCOUNTS_PDB.

Correct Answer: D
