QUESTION 106
As part of a manual upgrade process, after installing the software for Oracle Database 12c and preparing the new Oracle home, you shut down the existing single-instance database. Which step should you perform next to start the upgrade of the database?

A.    Start up the database instance by using the new location of the server parameter file and run the catuppst.sqi script to generate informational messages and log files during the upgrade.
B.    Start up the database instance by using the new location of the server parameter file and run the cact1.pl script from the new Oracle home to use parallel upgrade options that reduce down time.
C.    Start up the database instance by using the STARTUP UPGRADEcommand and gather fixed object statistics to minimize the time needed for recompilation.
D.    Start up the database instance by using the STARTUPUPGRADEcommand, which opens the existing database, and then performs additional upgrade operations.

Answer: D

QUESTION 107
Examine the command to duplicate a database:
RMAN> DUPLICATE TARGET DATABASE TO cdb
PLUGGABLE DATABASE pdb1, pdb5;
Which two statements are true about the DUPLICATE command?

A.    The SPFILE is copied along with the data files of the pluggable databases (PDBs). The root and the seed database in the container database (CDB) are also duplicated.
B.    A backup of pdbi and pd35 must exist before executing the command.
C.    The duplicate command first creates a backup, and then duplicates the PDBs by using the backup.
D.    An auxiliary instance must be started with the initialization parameter ENABLE_PLUGGABLE_DATABASE set to TRUE.

Answer: BD
Explanation:
Do backups of the source database exist?
The principal advantage of active database duplication is that it does not require source database backups. Active duplication copies mounted or online database files over a network to the auxiliary instance. One disadvantage of this technique is the negative performance effect on the network. Another disadvantage is that the source database is running processes required to transfer the files to the auxiliary host, thereby affecting the source database and production workload. If the source database backups exist, and if the effect on the network is unacceptable, then backup-based duplication may be a better option. You can copy backups to temporary storage and transfer them manually to the destination host. If duplication is made with a connection to the target or the recovery catalog, then the backup files on the destination host must have the same file specification as they had on the source host. Otherwise, this is not a requirement.

QUESTION 108
Which two statements are true about scheduling operations in a pluggable database (PDB)?

A.    Scheduler jobs for a PDB can be defined only at the container database (CDB) level.
B.    A job defined in a PDB runs only if that PDB is open.
C.    Scheduler attribute setting is performed only at the CDB level.
D.    Scheduler objects created by users can be exported or imported using Data Pump.
E.    Scheduler jobs for a PDB can be created only by common users.

Answer: BD
Explanation:
In general, all scheduler objects created by the user can be exported/imported into the PDB using data pump. Predefined scheduler objects will not get exported and that means that any changes made to these objects by the user will have to be made once again after the database has been imported into the pluggable database. However, this is how import/export works currently. A job defined in a PDB will run only if a PDB is open.

QUESTION 109
A complete database backup to media is taken for your database every day. Which three actions would you take to improve backup performance?

A.    Set the backup_tape_io_slaves parameter to true.
B.    Set the dbwr_io_slaves parameter to a nonzero value if synchronous I/O is in use.
C.    Configure large pool if not already done.
D.    Remove the rate parameter, if specified, in the allocate channel command.
E.    Always use RMAN compression for tape backups rather than the compression provided by media manager.
F.    Always use synchronous I/O for the database.

Answer: BCD
Explanation:
Tuning RMAN Backup Performance: Procedure
Many factors can affect backup performance. Often, finding the solution to a slow backup is a process of trial and error. To get the best performance for a backup, follow the suggested steps in this section:
Step 1: Remove RATE Parameters from Configured and Allocated Channels
Step 2: If You Use Synchronous Disk I/O, Set DBWR_IO_SLAVES
Step 3: If You Fail to Allocate Shared Memory, Set LARGE_POOL_SIZE
Step 4: Tune RMAN Tape Streaming Performance Bottlenecks
Step 5: Query V$ Views to Identify Bottlenecks

QUESTION 110
For which three pieces of information can you use the RMAN list command?

A.    stored scripts in the recovery catalog
B.    available archived redo log files
C.    backup sets and image copies that are obsolete
D.    backups of tablespaces
E.    backups that are marked obsolete according to the current retention policy

Answer: ABD
Explanation:
About the LIST Command:
The primary purpose of the LIST command is to list backup and copies. For example, you can list:
– Backups and proxy copies of a database, tablespace, datafile, archived redo log, or control file
– Backups that have expired
– Backups restricted by time, path name, device type, tag, or recoverability
– Archived redo log files and disk copies

A.    It can contain a nested chain of jobs.
B.    It can be used to implement dependency-based scheduling.
C.    It cannot invoke the same program or nested chain in multiple steps in the chain.
D.    It cannot have more than one dependency.
E.    It can be executed using event-based or time-based schedules.

Answer: ABE
Explanation:
Chains are the means by which you can implement dependency based scheduling, in which jobs are started depending on the outcomes of one or more previous jobs.

QUESTION 113
Because of logical corruption of data in a table, you want to recover the table from an RMAN backup to a specified point in time. Examine the steps to recover this table from an RMAN backup:
1. Determine which backup contains the table that needs to be recovered.
2. Issue the recover table RMAN command with an auxiliary destination defined and the point in time specified.
3. Import the Data Pump export dump file into the auxiliary instance.
4. Create a Data Pump export dump file that contains the recovered table on a target database.
Identify the required steps in the correct order.

A.    1, 4, 3
B.    1, 2
C.    1, 4, 3, 2
D.    1, 2, 4

Answer: B
Explanation:
Because according to oracle PDFs if you run restore table … auxiliary a impede and rename can be included. So there is no reason to make the import manually if it can be already included in step 2.

QUESTION 115
Which two are prerequisites for setting up Flashback Data Archive?

A.    Fast Recovery Area should be defined.
B.    Undo retention guarantee should be enabled.
C.    Supplemental logging should be enabled.
D.    Automatic Undo Management should be enabled.
E.    All users using Flashback Data Archive should have unlimited quota on the Flashback Data Archive tablespace.
F.    The tablespace in which the Flashback Data Archive is created should have Automatic Segment Space Management (ASSM) enabled.

Answer: DF
Explanation:
http://www.dba-oracle.com/t_11g_new_enabling_fdba.htm
There are a number of restrictions for flashback archives:
The tablespaces used for a flashback archive must use local extent management and automatic segment space management.
The database must use automatic undo management.

QUESTION 116
The environmental variable oracle_Base is set to /u01/app/oracle and oracle_home is set to /u01/app/oracle/product/12.1.0/db 1. You want to check the diagnostic files created as part of the Automatic Diagnostic Repository (ADR). Examine the initialization parameters set in your database.
NAMETYPEVALUE
——————————————– ——————- ——
audit_file_deststring/u01/app/oracle/admin/eml2rep/adump
background_dump_deststring
core_dump_deststring
db_create_file_deststring
db_recovery_file_deststring/u01/app/oracle/fast_recovery_area
diagnostic_deststring
What is the location of the ADR base?

A.    It is set to/u01/app/oracle/product:/12.1.0/db_1/log.
B.    It is set to /u01/app/oracle/admin/enl2r&p/adump.
C.    It is set to /u01/app/oracle.
D.    It is setto /u01/app/oracle/flash_recovery_area.

Answer: C
Explanation:
The Automatic Diagnostic Repository (ADR) is a directory structure that is stored outside of the database. It is therefore available for problem diagnosis when the database is down.
The ADR root directory is known as ADR base. Its location is set by the DIAGNOSTIC_DEST initialization parameter. If this parameter is omitted or left null, the database sets DIAGNOSTIC_DEST upon startup as follows:
If environment variable ORACLE_BASE is set, DIAGNOSTIC_DEST is set to the directory designated by ORACLE_BASE.
If environment variable ORACLE_BASE is not set, DIAGNOSTIC_DEST is set to ORACLE_HOME/log.

QUESTION 117
You want to export the pluggable database (PDB) hr pdb1 from the multitenant container database (CDB)CDB1 and import it into the cdb2 CDB as the emp_pdb1 PDB. Examine the list of possible steps required to perform the task:
1. Create a PDB named emp_pdb1.
2. Export the hr_pdb1 PDB by using the full clause.
3. Open the emp_pdb1 PDB.
4. Mount the emp_pdb1 PDB.
5. Synchronize the emp_pdb1 PDB in restricted mode.
6. Copy the dump file to the Data Pump directory.
7. Create a Data Pump directory in the emp_pdb1 PDB.
8. Import data into emp_pdb1 with the full and remap clauses.
9. Create the same tablespaces in emp_pdb1 as in hr_pdb1 for new local user objects.
Identify the required steps in the correct order.

A.    2, 1, 3, 7, 6, and 8
B.    2, 1, 4, 5, 3, 7, 6, 9, and 8
C.    2, 1, 3, 7, 6, 9, and 8
D.    2, 1, 3, 5, 7, 6, and 8

Answer: A
Explanation:
Because the step 2 says that you perfom an expdp with the full clause and you dont need to create the tablespaces when you perform the impdp.
FULL=yes will export tablespace definitions. So no need step 9.

QUESTION 118
You wish to create jobs to satisfy these requirements:
1. Automatically bulk load data from a flat file.
2. Rebuild indexes on the SALES table after completion of the bulk load.
How would you create these jobs?

A.    Create both jobs by using Scheduler raised events.
B.    Create both jobs using application raised events.
C.    Create one job to rebuild indexes using application raised events and another job to perform bulk load using Scheduler raised events.
D.    Create one job to rebuild indexes using Scheduler raised events and another job to perform bulk load by using events raised by the application.

Answer: C
Explanation:
The bulk loader would be started in response to a file watcher scheduler event and the indexes would be rebuilt in response to an application event raised by the bulk loader.
https://docs.oracle.com/cd/E18283_01/server.112/e17120/scheduse005.htm#CIABIEJA
Your application can raise an event to notify the Scheduler to start a job. A job started in this way is referred to as an event-based job. The job can optionally retrieve the message content of the event.

QUESTION 119
Your Oracle 12c multitenant container database (CDB) contains multiple pluggable databases (PDBs). In the PDB hr_pdb, the common user c##admin and the local user b_admin have only the connect privilege. You create a common role c##role1 with the create table and select any table privileges. You then execute the commands:
SQL> GRANTc##role1 TOcMadmin CONTAINER=ALL;
SQL> CONNsys/oracle@HR_PDB assysdba;
SQL> GRANTc##role1TO b_admin CONTAINER=CURRENT;
Which two statements are true?

A.    C##admin can create and select any table, and grant the c##role1 role to users only in the root container.
B.    B_admin can create and select any table in both the root container and kr_pdb.
C.    c##admin can create and select any table in the root container and all the PDBs.
D.    B_admin can create and select any table only in hr_pdb.
E.    The grant c=>role1 to b_admin command returns an error because container should be set to ALL.

Answer: CD

QUESTION 120
Examine the commands executed in the root container of your multitenant container database (CDB) that has multiple pluggable databases (PDBs):
SQL> CREATE USER c##a_admin IDENTIFIED BY orcl123;
SQL> CREATE ROLE c##role1 CONTAINER=ALL;
SQL> GRANT CREATE VIEW TO C##roleI CONTAINER=ALL;
SQL> GRANT c##role1 TO c##a_admin CONTAINER=ALL;
SQL> REVOKE c##role1 FROM c##a_admin;
What is the result of the revoke command?

A.    It executes successfully and the c##role1 role is revoked from the c##a_admin user only in the root container.
B.    It fails and reports an error because the container=all clause is not used.
C.    It executes successfully and the c##rocl1role is revoked from the c##a_adminuser in the root database and all the PDBs.
D.    It fails and reports an error because the comtainer=currentclause is not used.

Answer: B
Explanation:
SQL> REVOKE c##role1 FROM c##a_admin;
REVOKE c##role1 FROM c##a_admin
*
ERROR at line 1:
ORA-01951: ROLE ‘C##ROLE1’ not granted to ‘C##A_ADMIN’
SQL> REVOKE c##role1 FROM c##a_admin CONTAINER=ALL;
Revoke succeeded.
SQL>
This CREATE USER c##a_admin IDENTIFIED BY orcl123; will create common user event container is not specified.
