Which two statements are true?
A. The C # # ROLE1 role is created in the root database and all the PDBs.

Answer: CDE
Q3. Your multitenant container database (CDB) is running in ARCHIVELOG mode. You connect to the CDB RMAN.

Which data files will be backed up?
A. Data files that belong to only the root container
B. Data files that belong to the root container and all the pluggable databases (PDBs)
C. Data files that belong to only the root container and PDB$SEED

Answer: B
Q4. Which two statements are true concerning the 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.
Answer: AE
Q5. Identify three valid methods of opening, pluggable databases (PDBs).

B. ALTER PLUGGABLE DATABASE OPEN ALL ISSUED from a PDB
C. ALTER PLUGGABLE DATABASE PDB OPEN issued from the seed
D. ALTER DATABASE PDB OPEN issued from the root
E. ALTER DATABASE OPEN issued from that PDB

Answer: AEG
Q6. You performed an incremental level 0 backup of a database:
RMAN > BACKUP INCREMENTAL LEVEL 0 DATABASE;
To enable block change tracking after the incremental level 0 backup, you issued this command:
SQL > ALTER DATABASE ENABLE BLOCK CHANGE TRACKING USING FILE
‘ /mydir/rman_change_track.f’;
To perform an incremental level 1 cumulative backup, you issued this command: RMAN> BACKUP INCREMENTAL LEVEL 1 CUMULATIVE DATABASE;
Which three statements are true?
A. Backup change tracking will sometimes reduce I/O performed during cumulative incremental backups.
B. The change tracking file must always be backed up when you perform a full database backup.
C. Block change tracking will always reduce I/O performed during cumulative incremental backups.
D. More than one database block may be read by an incremental backup for a change made to a single block.
E. The incremental level 1 backup that immediately follows the enabling of block change tracking will not read the change tracking file to discover changed blocks.
Answer: ADE
Q7. What is the result of executing a TRUNCATE TABLE command on a table that has Flashback Archiving enabled?
A. It fails with the ORA-665610 Invalid DDL statement on history-tracked message
B. The rows in the table are truncated without being archived.
C. The rows in the table are archived, and then truncated.
D. The rows in both the table and the archive are truncated.
Answer: C
Q8. Which three statements are true about SQL plan directives?
A. They are tied to a specific statement or SQL ID.
B. They instruct the maintenance job to collect missing statistics or perform dynamic sampling to generate a more optimal plan.
C. They are used to gather only missing statistics.
D. They are created for a query expression where statistics are missing or the cardinality estimates by the optimizer are incorrect.
E. They instruct the optimizer to create only column group statistics.
F. Improve plan accuracy by persisting both compilation and execution statistics in the SYSAUX tablespace.
Answer: BDF
Q9. You executed a DROP USER CASCADE on an Oracle 11g release 1 database and immediately realized that you forgot to copy the OCA. EXAM_RESULTS table to the OCP schema.
The RECYCLE_BIN enabled before the DROP USER was executed and the OCP user has been granted the FLASHBACK ANY TABLE system privilege.
What is the quickest way to recover the contents of the OCA. EXAM_RESULTS table to the OCP schema?
A. Execute FLASHBACK TABLE OCA. EXAM_RESULTS TO BEFORE DROP RENAME TO OCP.EXAM_RESULTS; connected as SYSTEM.
B. Recover the table using traditional Tablespace Point In Time Recovery.
C. Recover the table using Automated Tablespace Point In Time Recovery.
D. Recovery the table using Database Point In Time Recovery.
E. Execute FLASHBACK TABLE OCA. EXAM_RESULTS TO BEFORE DROP RENAME TO EXAM_RESULTS; connected as the OCP user.
Answer: C
Q10. You execute the following commands to audit database activities:
SQL > ALTER SYSTEM SET AUDIT_TRIAL=DB, EXTENDED SCOPE=SPFILE;
SQL > AUDIT SELECT TABLE, INSERT TABLE, DELETE TABLE BY JOHN By SESSION WHENEVER SUCCESSFUL;

A. One audit record is created for every successful execution of a SELECT, INSERT OR DELETE command on a table, and contains the SQL text for the SQL Statements.
B. One audit record is created for every successful execution of a SELECT, INSERT OR DELETE command, and contains the execution plan for the SQL statements.
C. One audit record is created for the whole session if john successfully executes a SELECT, INSERT, or DELETE command, and contains the execution plan for the SQL statements.
D. One audit record is created for the whole session if JOHN successfully executes a select command, and contains the SQL text and bind variables used.
E. One audit record is created for the whole session if john successfully executes a SELECT, INSERT, or DELETE command on a table, and contains the execution plan, SQL text, and bind variables used.
Answer: D
