You want to create a duplicate database DUP_DB from your production database PROD on the same host. The PROD database uses Automatic Storage Management (ASM) for storage. Regular backups are taken using RMAN connected to a recovery catalog. You create an auxiliary instance and want to execute the command: RMAN> DUPLICATE TARGET DATABASE TO dup_db FROM ACTIVE DATABASE;
What is a prerequisite for the successful execution of this command?
A. RMAN must be connected to the target database instance and the auxiliary instance.
B. A most recent backup set of the PROD database must exist.
C. Flashback must be enabled for the PROD database.
D. The target database must be in MOUNT state.
Which three are true about Data Pump in an Oracle multitenant environment? (Choose three).
A. It can be used to transport data from a non-CDB to a PDB.
B. It can be used to clone a CDB.
C. It can be used to transport data between PDBs.
D. It can be used to transport data from a PDB to a non-CDB.
E. It can be used to create a new PDB.
Examine the command to duplicate a database: RMAN> DUPLICATE TARGET DATABASE TCddb PLUGGABLE DATABASE pdbl,pdb5; Which two statements are true about the DUPLICATE command? (Choose two)
A. The root and the seed database in the container database (CDB) are also duplicated.
B. A backup of PDB1 and PDB5 must exist before executing the command.
C. The SPFILE is copied along with the data files of the pluggable databases (PDBs).
D. An auxiliary instance must be started with the initialization parameter ENABLE_PLUGGABLE_DATABASE set to TRUE.
E. The DUPLICATE command first creates a backup, and then duplicates the PDBs by using the backup.
Which two statements are true about Resource Manager plans for individual pluggable databases (PDB plans) in a multitenant container database (CDB)?
A. If no PDB plan is enabled for a pluggable database, then all sessions for that PDB are treated to an equal degree of the resource share of that PDB.
B. In a PDB plan, subplans may be used with up to eight consumer groups.
C. If a PDB plan is enabled for a pluggable database, then resources are allocated to consumer groups across all PDBs in the CDB.
D. If no PDB plan is enabled for a pluggable database, then the PDB share in the CDB plan is dynamically calculated.
E. If a PDB plan is enabled for a pluggable database, then resources are allocated to consumer groups based on the shares provided to the PDB in the CDB plan and the shares provided to the consumer groups in the PDB plan.
On the 10th of August, you implement an incremental database backup strategy and configure a recovery window of five days.
Level 0 backups are taken on the 10th, 17th, and 24th of August. Differential level 1 incremental backups are taken daily between the level 0 backups.
Today is the 26th of August.
Which backups will be obsolete?
A. all backups prior to 10th of August
B. all backups prior to 22nd of August
C. all backups prior to 24th of August
D. all backups prior to 20th of August
E. all backups prior to 17th of August
Which are the three steps in the SQL tuning process for Oracle Database environments? (Choose three).

C. Test the application as a whole using tuned SQL statements.
D. Test tuned SQL statements one at a time for all statements in the application.
E. Identify poorly tuned SQL statements using the SQL Tuning Advisor.

Which three statements are true about Automatic Workload Repository (AWR)?
A. All AWR tables belong to the SYSTEM schema.
B. The AWR data is stored in memory and in the database.
C. The snapshots collected by AWR are used by the self-tuning components in the database
D. AWR computes time model statistics based on time usage for activities, which are displayed in the v$SYS time model and V$SESS_TIME_MODEL views.
E. AWR contains system wide tracing and logging information.
