Q31. Which three statements are true about the database instance startup after an instance failure?
A. The RECO process recovers the uncommitted transactions at the next instance startup.
B. Online redo log files and archived redo log files are required to complete the rollback stage of instance recovery.
C. Uncommitted changes are rolled back to ensure transactional consistency.
D. The SMON process automatically performs the database recovery.
E. Media recovery is required to complete the database recovery.
F. Changes committed before the failure, which were not written to the data files, are re-applied.
Q32. You are administering a database that supports a data warehousing workload and is running in noarchivelog mode. You use RMAN to perform a level 0 backup on Sundays and level 1 incremental backups on all the other days of the week.
One of the data files is corrupted and the current online redo log file is lost because of a media failure.
Which action must you take for recovery?
A. Restore the data file, recover it by using the recover datafilenoredo command, and use the resetlogs option to open the database.
B. Restore the control file and all the data files, recover them by using the recover database noredo command, and use the resetlogs option to open the database.
C. Restore all the data files, recover them by using the recover database command, and open the database.
D. Restore all the data files, recover them by using the recover database noredo command, and use the resetlogs option to open the database.
Q33. On your Oracle 12c database, you invokeSQL*Loaderto load data into the employees table
in the hr schema by issuing the command:
Which two statements are true about the command?
A. It succeeds with default settings if the employees table exists in the hr schema.
B. It fails because noSQL*Loaderdata file location is specified.
C. It fails if the hr user does not have the create any directory privilege.
D. It fails because noSQL*Loadercontrol file location is specified.
E. It succeeds and creates the employees table in theHRschema.
Q34. Your multitenant container database (CDB) cdb1 that is running in archivelog mode contains two pluggable databases (PDBs), pdb2_1 and pdb2_2. RMAN is connected to the target database pdb2_1.
Examine the command executed to back up pdb2_1:
RMAN> BACKUP DATABASE PLUS ARCHIVELOG;
Which statement is true about the execution of this command?
A. It fails because archive log files cannot be backed up using a connection to a PDB.
B. It succeeds but only the data files belonging to the pdb2_i pluggable database are backed up.
C. It succeeds and all data files belonging to PD32_i are backed up along with the archive log files.
D. It fails because the pluggable clause is missing.
Q35. The CATDB12C database contains an Oracle Database 12c catalog schema owned by the rci2c user.
The CATD3H database contains an Oracle Database Ug catalog schema owned by the rch user.
A database with dbid=H2324I is registered in the catdbII catalog. Both the recovery catalog databases are open.
In the CATD3i2c database, you execute the commands:
RKAN> CONNECT CATALOG rci2c/passI2c@catdbi2c
RKAN> IMPORT CATALOG rcii/pwdcatUQcatdfoil DBI2=142324i;
What is the outcome of the import?
A. It fails because the target database and recovery catalog database are of different versions.
B. It succeeds and all global scripts in the rci: catalog that have the same name as existing global scripts in the RCI2C catalog are automatically renamed.
C. It succeeds but the database is not automatically registered in the rc:2c catalog.
D. It fails because RMAN is not connected to the target database with r3:T=:42324:.
Q36. You notice that the performance of your production 24x7 Oracle 12c database has significantly degraded. Sometimes, you are not able to connect to the database instance because it hangs.
How can you detect the cause of the degraded performance?
A. by performing emergency monitoring using Real-Time Automatic Database Diagnostic Monitor (ADDM) to fetch data directly from SGA for analysis
B. by running ADDM to fetch information from the latest Automatic Workload Repository (AWR) snapshots
C. by using Active Session History (ASH) data and performing hang analysis
D. by running ADDM in diagnostic mode
Q37. You create a default Flashback Data Archive FLA1and enable it for the
EMPLOYEEStablein the HRschema.
After a few days, you want to alter the EMPLOYEEStable by executing the command:
SQL> ALTER TABLEEMPLOYEES ADD PHONE NUMBER(12);
Which statement is true about the execution of the command?
A. It gives an error because DDL statements cannot be executed on a table that is enabled for Flashback Data Archive.
B. It executes successfully and all metadata related to the EMPLOYEEStable before altering the table definition is purged from Flashback Data Archive.
C. It executes successfully and continues to store metadata related to the EMPLOYEEStable.
D. It executes successfully but Flashback Data Archive is disabled for the EMPLOYEEStable.
Q38. Which two statements are true about Flashback Version Query?
A. The result of a query can be used as part of a DML statement.
B. It can be used to create views.
C. It can be used only if Flashback Data Archive is enabled for a table.
D. It retrieves all versions of rows that exist in a time interval, including the start time and end time.
E. It can be used to retrieve the SQL that is required to undo a row change and the user responsible for the change.
Q39. Which two are direct benefits of the multiprocess, multithreaded architecture of Oracle Database 12c when it is enabled?
A. Reduced logical I/O
B. Reduced virtual memory utilization
C. Improved Serial Execution performance
D. Reduced physical I/O
E. Reduced CPU utilization
Q40. In your multitenant container database (CDB) that contains pluggable databases (PDBs), the hr user executes the following commands to create and grant privileges on a procedure:
INSERT INTO hr.test VALUES (v_emp_id, v_ename, v salary, v_dept_id);
GRANT EXECUTE ON CREATE_TEST TO John, jim, smith, king;
How can you prevent users having the execute privilege on the create_test_v procedure from inserting values into tables on which they do not have any privileges?
A. Create the create_test procedure with definer's rights.
B. Grant the execute privilege to users with grant option on the create_test procedure.
C. Create the create_test procedure with invoker's rights.
