Questions 13

RMAN is connected to the target database prod1 and an auxiliary instance in nomount state. Examine the command to create a duplicate database: RMAN> DUPLICATE TARGET DATABASE TO dup1 FROM ACTIVE DATABASE NOFILENAMECHECK PASSWORD FILE SPFILE; Which two statements are true about the execution of the duplicate command?

Options:

All archive redo log files are automatically copied to the duplicate database.

The duplicate database has the same directory structure as the source database.

The duplicate database is created by using the backups created during the execution of

he duplicate command.

The password file and SPFILE for the duplicate database dup1 are created in their respective default locations.

The duplicate database is created without using RMAN backups and prod1 is allowed to remain open during duplication.

Questions 14

Which three actions are performed by Database Upgrade Assistant (DBUA)? (Choose three.)

Options:

It recompiles all stored PL/SQL code by using utlrp.sql.

It empties the RECYCLE BIN.

It sets all user tablespaces to “read-only” before starting the upgrade.

It removes the AUDSYS schema and the AUDIT_ADMIN and AUDIT_VIEWER roles

It increases tablespace size, if required, to meet upgrade requirements.

Questions 15

You are administering a multitenant container database (COB) that contains two pluggable databases (PDBs), pdb1 and pdb2. You are connected to pdb2 as a common user with DBA privileges. The statistics_level parameter is PDB modifiable. As the user sys, execute the following command on pdb2: SQL> ALTER SYSTEM SET STATISTICS_LEVEL=ALL SID='*' SCOPE=SPFILE; Which statement is true about the result of this command?

Options:

The statistics_level parameter is set to all when any of the PDBs is reopened.

The statistics_level parameter is set to all only for PDB2 when it is reopened.

The statistics_level parameter is set to all when the root database is restarted.

The statement is ignored because there is no SPFILE for a PDB.

Questions 16

You execute this command successfully: SQL> ALTER DATABASE BACKUP CONTROLFILE TO TRACE; What is the outcome?

Options:

It creates a binary backup of the control file.

It updates the alert log with the location and contents of the control file

It creates a file that contains SQL statements to re-create the control file.

It creates a file that contains RMAN scripts to create a duplicate database.

An Oracle database can be restored from backup files copied using O/S utilities.

Oracle data file backups, copied using an O/S utility, can be added to the RMAN catalog as IMAGE COPIES.

Backing up a database in NOARCHIVELOG mode using O/S utilities requires that the database instance be shut down.

Oracle archive log backups, copied using an O/S utility, can be added to the RMAN catalog as a backup set.

Backing up a database in ARCHIVE LOG mode using O/S utilities requires that the database instance be started and the database be in OPEN state.
