NO.136 Which two are true about creating RMAN backups for an Oracle container database? (Choose two.)

Tablespaces from different PDBs with identical names must be backed up by connecting RMAN separately to each PDB to back up the tablespaces.

The BACKUP DATABASE command will create a pluggable database (PDB) backup when RMAN is connected to a PDB.

SPFILE backups can be created while connected to an application root PDB.

The BACKUP DATABASE PLUS ARCHIVE LOG command will back up archive logs when RMAN is connected to a PDB.

The BACKUP PLUGGABLE DATABASE command can be used to back up CDB$ROOT.

NO.137 Which two are true about the Oracle dataabse methodology? (Choose two.)

The Oracle Database time model should be used to find the database and instance areas most in need of tuning.

Tuning activities should stop once the user is satisfied with performance.

Tuning activities should stop once agreed service levels for performance have been met.

The database instance memory should always be tuned before tuning any file systems.

SQL statements should always be tuned before tuning any file systems.

The alert log should be used to find the database and instance areas most in need of tuning.

NO.138 Which two are true about RMAN persistent configuration settings, administration, and their effects?

A target database’s persistent RMAN configuration settings are always stored in the target’s control file

Backups written to the fast recovery area (FRA) that are obsolete based on the redundancy retention policy can be deleted automatically to free space.

A DBA must specify either a redundancy retention policy or a recovery window retention policy.

A target database’s persistent RMAN configuration settings are always synchronized automatically with the RMAN catalog.

Backups older than the recovery window retention policy are always deleted automatically if the backup location has insufficient space.

NO.139 You have configured RMAN SBT channels to write backups to media.
You then take an RMAN backup by using this command:

Which three are true? (Choose three.)

The restore point is a label for the system change number (SCN) that will be saved two years after the archival backup was taken.

The data file backups in the self-contained archive backup are not considered obsolete for two years regardless of the retention policy.

All archive logs created after this backup are kept for two years.

The SPFILEis included in the self-contaied archival backup.

The control file is included in the self-contained archival backup.

The restore point is a label for the system change number (SCN) before the archival backup was taken.

NO.140 Choose three. Which three are true about a whole database backup?

It can be created only by using RMAN.

It always includes all data files, the current control file, the server parameter file, and archived redo logs.

It can be consistent.

It is the only possible backup type for a database in NOARCHIVELOG mode.

It can consist of either backup sets or image copies. F) It can be inconsistent.

NO.141 Which three actions will add a resource to an Oracle Restart configuration? (Choose three.)

creating an Oracle Database service by modifying the SERVICE_NAMES parameter

creating a disk group using the CREATE DISKGROUP SQL statement

creating a database using the CREATE DATABASE SQL statement

creating a database service using DBMS_SERVICE.CREATE_SERVICE

creating a database service using Oracle Database Configuration Assistant (DBCA)

creating an Oracle Automatic Storage Management (ASM) instance with ASM Configuration Assistant (ASMCA)

NO.142 Which two are true about Oracle instance recovery? (Choose three.)

Recovery begins from the beginning of the CURRENT redo log group.

Recovery begins from the last checkpoint position that was calculated by the Database Writer before instance failure.

Recovery begins from the start of any ACTIVE redo log group or the start of the CURRENT log group if no other group is ACTIVE.

Recovery reads redo until the end of the redo thread. SMON rolls back any dead transactions, and then the datanase is opened.

Recovery begins from the last checkpoint position that was recorded in the control file by the checkpoint process (CKPT).

Recovery reads redo until the end of the redo thread, and then opens the database. SMON then rolls back any dead transactions.

NO.143 Which two are true about RMAN encryption? (Choose two.)

RMAN encryption keys are stored in a database keystore.

RMAN can encrypt the Oracle Database password file.

Dual-mode encrypted backups can be restored only if both the password and the keystore used for encryption are available.

The SET ENCRYPTION command overrides encryption settings specified by the CONFIGURE ENCRYPTION command.

Password encryption can be persistently configured using the CONFIGURE ENCRYPTION command.

NO.144 Which three are true about requirements for various FLASHBACKoperations? (Choose three.)

FLASHBACKtransaction query requires undo to retrieve all versions of a row that existed between two points in time.

FLASHBACKdrop requires that the RECYCLEBIN parameter be set to ON.

FLASHBACKversion query requires that the RECYCLEBINparameter be set to ON.

FLASHBACK DATA ARCHIVErequires undo to store all versions of all rows of a table being tracked.

FLASHBACKdrop requires undo to retrieve all versions of a row that existed between two points in time.

FLASHBACKversion query requires undo to retrieve all versions of a row that existed between two points in time.

NO.145 Your SALES_ROOT application container has two application PDBs.
The SALES_APP application has a common table, FIN.REVENUE, in the two PDBs.
Examine this query and its output:

Which two are true? (Choose two.)

The CONTAINERS clause cannot be used in queries on the REVENUE table.

The REVENUE table must be a list-partitioned table.

The MAPTABLE tables defines a logical partition key on a commonly used column for the REVENUE table.

The MAPTABLE table is a metadata-linked table.

A container map exists for the REVENUE table, but is not enabled.

The REVENUE table partitions are not pruned across the PDBs automatically.

NO.146 Examine these queries and their output: After a system crash, an instance restart and an attempted opening of the PDBs result in: Which two are true? (Choose two.)

Data file 24 can be recovered while PDB2 is opened.

Data file 24 must be recovered while the CDB is opened.

Data file 24 can be recovered while CDB$ROOT and PDB$SEED are opened.

Data file 24 cannot be recovered while the CDB is opened.

Data file 24 must be recovered while PDB2 is closed.

NO.147 Your production database is running in archivelog mode. You use RMAN with a recovery catalog to back up your database to media and the database is uniquely identified in the recovery catalog. You want to create a test database from the production database and allow the production database to remain open during the duplicate process. You restore the database backups to a new host with the same directory structure as the production database and want to use the recovery catalog for future backups after the database is successfully restored to the new host. How would you achieve this?

by using the RMAN switch command to set the new location for the data files

by using the RMAN duplicate command with nofilenamecheck to recover the database to the new host

by using the RMAN duplicate command with dbid and set new name for tablespace to recover the database to the new host

by creating a new database in the new host, and then using the RMAN recover command
