Which two are true about Oracle Database Configuration Assistant (DBCA) templates? (Choose two.). The General Purpose of Transaction Processing templates are most suitable when concurrency and recoverability are key criteria. Oracle DBCA templates can store only logical structure and not database files. New templates can only be created by modifying an existing user-created template. The Data Warehouse template is most suitable when transaction response time is the key criterion. Oracle DBCA templates can be used to create new databases and duplicate existing databases.

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: SELECT containers_default, container_map, table_name FROM dba_tables WHERE owner='FIN'; CONTAINERS_DEFAULT CONTAINER_MAP CONTAINER_MAP_OBJECT TABLE_NAME ------------------ ------------- --------------------- ---------- NO YES NO REVENUE NO NO YES MAPTABLE 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.

Your container database, CDB1, has an application container, HR_ROOT, with an application PDB, HR_PDB1. You have the required privilege to clone HR_PDB1 to container database CDB2, which does not contain HR_ROOT. Which two are always true? (Choose two.). CDB1 and CDB2 must be in shared undo mode. A common user must exist in CDB2 with the CREATE PLUGGABLE DATABASE privilege. All transactions in HR_PDB1 of CDB1 must commit before the cloning process starts. Cloning HR_ROOT automatically clones HR_PDB1. The HR_PDB1 clone created in CDB2 will be in mount state when cloning ends.

Which three are true about backup, restore, and recovery operations done without using Recovery Manager (RMAN)? (Choose three.). Backing up a database in NOARCHIVELOG mode using O/S utilities requires that the database instance be started and the database be in the MOUNT state. Backing up a database in ARCHIVELOG mode using O/S utilities requires that the database instance be started and the database be in MOUNT state. 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 ARCHIVELOG mode using O/S utilities requires that the database instance be started and the database be in OPEN state.

Examine this configuration: 1. CDB1 is a container database. 2. PDB1 and PDB2 are pluggable databases in CDB1. You execute these commands successfully: $ export ORACLE_SID=cdb1 $ sqlplus / as sysdba SQL> SHUTDOWN IMMEDIATE ... Oracle instance shut down. SQL> STARTUP MOUNT ... Database mounted. Which two are true? (Choose two.). PDB1 and PDB2 are in MOUNT state. Redo logs are opened. PDB1 and PDB2 are in READ ONLY state. CDB$ROOT is in MOUNT state. PDB$SEED is in READ ONLY state.

Examine this configuration: 1. CDB1 is a container database running in ARCHIVELOG mode. 2. Controlfiles of CDB1 are multiplexed in '/u01/app/oracle/oradata/CDB1/controlfile/controlfile01.ctl' and '/u02/app/oracle/fast_recover_area/cdb1/CDB1/controlfile02.ctl'. 3. The only backup of CDB1 was taken when CONTROLFILE AUTOBACKUP was OFF 4. SNAPSHOT CONTROLFILE NAME is '/u01/app/oracle/product/12.2.0.1/db_1/dbs/snapcf_cdb1.f'. While CDB1 is open, `˜/u02/app/oracle/fast_recover_area/cdb1/CDB1/controlfile02.ctl' is accidentally deleted. To recover from this critical failure, you execute these commands: $ rman target sys/oracle_4U@localhost:1521/cdb1 RMAN> SHUTDOWN ABORT ... Oracle instance shut down RMAN> STARTUP NOMOUNT RMAN> RESTORE CONTROLFILE FROM '/u01/app/oracle/oradata/CDB1/controlfile/controlfile01.ctl'; What will be the outcome?. It will create '$ORACLE_HOME/dbs/cdb1/CDB1/controlfile02.ctl'. It will create '/u01/app/oralce/oradata/CDB1/controlfile/controlfile02.ctl'. It will re-create '/u02/app/oracle/fast_recover_area/cdb1/CDB1/controlfile02.ctl'. It will create '/u01/app/oracle/product/12.2.0.1/db_1/dbs/snapcf_cdb1control02.ctl'. It will fail because there is no autobackup of the controlfiles.
