Q22. In your Database, the TBS PERCENT USED parameter is set to 60 and the TBS PERCENT FREE parameter is set to 20.
Which two storage-tiering actions might be automated when using information Lifecycle Management (ILM) to automate data movement?
A. The movement of all segments to a target tablespace with a higher degree of compression, on a different storage tier, when the source tablespace exceeds TBS PERCENT USED
B. Setting the target tablespace to read-only
C. The movement of some segments to a target tablespace with a higher degree of compression, on a different storage tier, when the source tablespace exceeds TBS PERCENT USED
D. Setting the target tablespace offline
E. The movement of some blocks to a target tablespace with a lower degree of compression, on a different storage tier, when the source tablespace exceeds TBS PERCENT USED
Q23. Examine the following command;
ALTER SYSTEM SET enable_ddl_logging = TRUE;
Which statement is true?
A. Only the data definition language (DDL) commands that resulted in errors are logged in the alert log file.

Q24. You find this query being used in your Oracle 12c database:
Which method a used by the optimizer to limit the rows being returned?
A. A filter is added to the table query dynamically using ROWNUM to limit the rows to 20 percent of the total rows
B. All the rows are returned to the client or middle tier but only the first 20 percent are returned to the screen or the application.
C. A view is created during execution and a filter on the view limits the rows to 20 percent of the total rows.
D. A TOP-N query is created to limit the rows to 20 percent of the total rows
Q25. In your multitenant container database (CDB) containing pluggable database (PDBs), you granted the CREATE TABLE privilege to the common user C # # A_ADMIN in root and all PDBs. You execute the following command from the root container:
SQL > REVOKE create table FROM C # # A_ADMIN;
What is the result?
A. It executes successfully and the CREATE TABLE privilege is revoked from C # # A_ADMIN in root only.
B. It fails and reports an error because the CONTAINER=ALL clause is not used.
C. It excludes successfully and the CREATE TABLE privilege is revoked from C # # A_ADMIN in root and all PDBs.
D. It fails and reports an error because the CONTAINER=CURRENT clause is not used.
E. It executes successfully and the CREATE TABLE privilege is revoked from C # # A_ADMIN in all PDBs.
Q26. Oracle Grid Infrastructure for a stand-alone server is installed on your production host before installing the Oracle Database server. The database and listener are configured by using Oracle Restart.
Examine the following command and its output:
$ crsctl config has
CRS-4622: Oracle High Availability Services auto start is enabled.
What does this imply?
A. When you start an instance on a high with SQL *Plus dependent listeners and ASM disk groups are automatically started.
B. When a database instance is started by using the SRVCTL utility and listener startup fails, the instance is still started.
C. When a database is created by using SQL* Plus, it is automatically added to the Oracle Restart configuration.
D. When you create a database service by modifying the SERVICE_NAMES initialization parameter, it is automatically added to the Oracle Restart configuration.

Q27. Examine the following query output:
You issue the following command to import tables into the hr schema:
$ > impdp hr/hr directory = dumpdir dumpfile = hr_new.dmp schemas=hr
Which statement is true?
A. All database operations performed by the impdp command are logged.
B. Only CREATE INDEX and CREATE TABLE statements generated by the import are logged.
C. Only CREATE TABLE and ALTER TABLE statements generated by the import are logged.
D. None of the operations against the master table used by Oracle Data Pump to coordinate its activities are logged.
Q28. Your multitenant container database, CDB1, is running in ARCHIVELOG mode and has two pluggable databases, HR_PDB and ACCOUNTS_PDB. An RMAN backup exists for the database.
You issue the command to open ACCOUNTS_PDB and find that the USERDATA. DBF data file for the default permanent tablespace USERDATA belonging to ACCOUNTS_PDB is corrupteD.
What should you do before executing the commands to restore and recover the data file in ACCOUNTS_PDB?
A. Place CDB1 in the mount stage and then the USERDATA tablespace offline in ACCOUNTS_PDB.
B. Place CDB1 in the mount stage and issue the ALTER PLUGGABLE DATABASE accounts_pdb CLOSE IMMEDIATE command.
C. Issue the ALTER PLUGGABLE DATABASE accounts_pdb RESTRICTED command.
D. Take the USERDATA tablespace offline in ACCOUNTS_PDB.
Q29. A redaction policy was added to the SAL column of the SCOTT.EMP table:
All users have their default set of system privileges.
For which three situations will data not be redacted?
A. SYS sessions, regardless of the roles that are set in the session
B. SYSTEM sessions, regardless of the roles that are set in the session
C. SCOTT sessions, only if the MGR role is set in the session
D. SCOTT sessions, only if the MGR role is granted to SCOTT
E. SCOTT sessions, because he is the owner of the table
F. SYSTEM session, only if the MGR role is set in the session
Q30. 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.
