NEW QUESTION 109
You plan to install the Oracle Database 12c software on a new server. The database will use Automatic Storage Management (ASM) and Oracle Restart. Oracle Grid Infrastructure for a standalone server is already installed on the server.
You want to configure job role separation. You create the following operating system users and groups:
- The user oracle as the owner of the Oracle database installation
- The user grid as the owner of Oracle Grid Infrastructure
- The group oinstall as an Oracle Inventory group
- The group dba as the OSDBA group for Oracle database
- The group asmdba as the OSDBA group for Oracle ASM

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. SCOTT sessions, only if the MGR role is set in the session
B. SYSTEM sessions, regardless of the roles that are set in the session
C. SYS sessions, regardless of the roles that are 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

Answer: C,D,F

Explanation:
* SYS_CONTEXT
This is a twist on the SYS_CONTEXT function as it does not use USERENV. With this usage SYS_CONTEXT queries the
list of the user's current default roles and returns TRUE if the role is granted.
Example:
SYS_CONTEXT('SYS_SESSION_ROLES', 'SUPERVISOR')
conn scott/tiger@pdborcl
SELECT sys_context('SYS_SESSION_ROLES', 'RESOURCE')
FROM dual;
SYS_CONTEXT('SYS_SESSION_ROLES','SUPERVISOR')
---------------------------------------------
FALSE
conn sys@pdborcl as sysdba
GRANT resource TO scott;
conn scott/tiger@pdborcl
SELECT sys_context('SYS_SESSION_ROLES', 'RESOURCE')
FROM dual;
SYS_CONTEXT('SYS_SESSION_ROLES','SUPERVISOR')
---------------------------------------------
TRUE

NEW QUESTION 111
You support Oracle Database 12c Oracle Database 11g, and Oracle Database log on the same server.
All databases of all versions use Automatic Storage Management (ASM).
Which three statements are true about the ASM disk group compatibility attributes that are set for a disk group? (Choose three.)

A. The RDBMS compatibility setting allows only databases set to the same version as the compatibility value, to mount the ASM disk group.
B. The ASM compatibility attribute controls the format of the disk group metadata.
C. The ADVM compatibility attribute determines the ACFS features that may be used by the Oracle 10 g database.
D. The ASM compatibility attribute determines some of the ASM features that may be used by the Oracle disk group.
E. RDBMS compatibility together with the database version determines whether a database Instance can mount the ASM disk group.

Answer: B,D,E

Explanation:
Explanation
Explanation:
AD: The value for the disk group COMPATIBLE.ASM attribute determines the minimum software version for an Oracle ASM instance that can use the disk group. This setting also affects the format of the data structures for the Oracle ASM metadata on the disk.
B: The value for the disk group COMPATIBLE.RDBMS attribute determines the minimum COMPATIBLE database initialization parameter setting for any database instance that is allowed to use the disk group. Before advancing the COMPATIBLE.RDBMS attribute, ensure that the values for the COMPATIBLE initialization parameter for all of the databases that access the disk group are set to at least the value of the new setting for COMPATIBLE.RDBMS.
For example, if the COMPATIBLE initialization parameters of the databases are set to either 11.1 or 11.2, then COMPATIBLE.RDBMS can be set to any value between 10.1 and 11.1 inclusively.
Not E:
/The value for the disk group COMPATIBLE.ADVM attribute determines whether the disk group can contain Oracle ASM volumes. The value must be set to 11.2 or higher. Before setting this attribute, the COMPATIBLE.ASM value must be 11.2 or higher. Also, the Oracle ADVM volume drivers must be loaded in the supported environment.
/ You can create an Oracle ASM Dynamic Volume Manager (Oracle ADVM) volume in a disk group. The volume device associated with the dynamic volume can then be used to host an Oracle ACFS file system.
The compatibility parameters COMPATIBLE.ASM and COMPATIBLE.ADVM must be set to 11.2 or higher for the disk group.
Note:
* The disk group attributes that determine compatibility are COMPATIBLE.ASM, COMPATIBLE.RDBMS. and COMPATIBLE.ADVM. The COMPATIBLE.ASM and COMPATIBLE.RDBMS attribute settings determine the minimum Oracle Database software version numbers that a system can use for Oracle ASM and the database instance types respectively. For example, if the Oracle ASM compatibility setting is 11.2, and RDBMS compatibility is set to 11.1, then the Oracle ASM software version must be at least 11.2, and the Oracle Database client software version must be at least 11.1. The COMPATIBLE.ADVM attribute determines whether the Oracle ASM Dynamic Volume Manager feature can create a volume in a disk group.

NEW QUESTION 112
You want to create a test database as a replica of your production database with minimum intervention from a DBA.
Which method would you use?

A. Create the database by using the CREATE DATAEASE. . .command and manually import data by using Data Pump.
B. Use DBCA to create a template from the existing database to contain the database structure and then manually copy the data by using Oracle Data Pump.
C. Use DBCA to create a template from the existing database to contain the database structure with data files and then use the same template to create the database in the new location.
D. Use Database Configuration Assistant (DBCA) to create a template from the existing database to contain the database structure.

Answer: B

NEW QUESTION 113
Which three statements are true concerning the multitenant architecture? (Choose three.)

A. PDBs share a common system tablespace.
B. Log switches occur only at the multitenant container database (CDB) level.
C. Instance recovery is always performed at the CDB level.
D. PDBs can share the sysaux tablespace.
E. A PDB can have a private temp tablespace.
F. Each pluggable database (PDB) has its own set of background processes.
G. Different PDBs can have different default block sizes.

Answer: B,C,E

Explanation:
Explanation
B:
* A PDB would have its SYSTEM, SYSAUX, TEMP tablespaces. It can also contains other user created tablespaces in it.
* There is one default temporary tablespace for the entire CDB. However, you can create additional temporary tablespaces in individual PDBs.
D:
* There is a single redo log and a single control file for an entire CDB
* A log switch is the point at which the database stops writing to one redo log file and begins writing to another. Normally, a log switch occurs when the current redo log file is completely filled and writing must continue to the next redo log file.
G: instance recovery
The automatic application of redo log records to uncommitted data blocks when an database instance is restarted after a failure.
Incorrect:
Not A:
* There is one set of background processes shared by the root and all PDBs.
* High consolidation density. The many pluggable databases in a single container database share its memory and background processes, letting you operate many more pluggable databases on a particular platform than you can single databases that use the old architecture.
Not C: There is a separate SYSAUX tablespace for the root and for each PDB.
Not F: There is a separate SYSTEM tablespace for the root and for each PDB.

NEW QUESTION 114
What is the result of executing a TRUNCATE TABLE command on a table that has
Flashback Archiving enabled?

A. The rows in both the table and the archive are truncated.
B. It fails with the ORA-665610 Invalid DDL statement on history-tracked message
C. The rows in the table are truncated without being archived.
D. The rows in the table are archived, and then truncated.

Answer: C

Explanation:
You cannot roll back a TRUNCATE TABLE statement, nor can you use a FLASHBACK
TABLE statement to retrieve the contents of a table that has been truncated.

NEW QUESTION 115
Your database is open and the LISTENER listener running. You stopped the wrong listener LISTENER by issuing the
following command:
1snrctl > STOP
What happens to the sessions that are presently connected to the database Instance?

A. They are not allowed to perform any operations until the listener LISTENER is started.
B. They are not affected and continue to function normally.
C. They are terminated and the active transactions are rolled back.
D. They are able to perform only queries.

Answer: B

Explanation:
The listener is used when the connection is established. The immediate impact of stopping the listener will be that no
new session can be established from a remote host. Existing sessions are not compromised.

NEW QUESTION 116
Which two statements are true concerning dropping a pluggable database (PDB)?

A. A dropped PDB can never be plugged back into a multitenant container database (CDB).
B. The PDB must be open in read-only mode.
C. The PDB must be unplugged.
D. The PDB must be in mount state.
E. The PDB data files are always removed from disk.

Answer: C,D

NEW QUESTION 117
You are administering a database and you receive a requirement to apply the following restrictions:
1. A connection must be terminated after four unsuccessful login attempts by user.
2. A user should not be able to create more than four simultaneous sessions.
3. User session must be terminated after 15 minutes of inactivity.
4. Users must be prompted to change their passwords every 15 days.
How would you accomplish these requirements?

A. By creating and assigning a profile to the users and setting the SEC_MAX_FAILED_LOGIN_ATTEMPTS parameter to 4
B. By implementing the database resource Manager plan and setting the
SEC_MAX_FAILED_LOGIN_ATTEMPTS parameters to 4.
C. By Implementing Fine-Grained Auditing (FGA) and setting the REMOTE_LOGIN_PASSWORD_FILE parameter to NONE.
D. by creating and assigning a profile to the users and setting the REMOTE_OS_AUTHENT parameter to FALSE
E. by granting a secure application role to the users

Answer: E

Explanation:
You can design your applications to automatically grant a role to the user who is trying to log in, provided the user meets criteria that you specify. To do so, you create a secure application role, which is a role that is associated with a PL/SQL procedure (or PL/SQL package that contains multiple procedures). The procedure validates the user: if the user fails the validation, then the user cannot log in. If the user passes the validation, then the procedure grants the user a role so that he or she can use the application. The user has this role only as long as he or she is logged in to the application. When the user logs out, the role is revoked.
Incorrect:
Not B: REMOTE_OS_AUTHENT specifies whether remote clients will be authenticated with the value of the OS_AUTHENT_PREFIX parameter.
Not C, not E: SEC_MAX_FAILED_LOGIN_ATTEMPTS specifies the number of authentication attempts that can be made by a client on a connection to the server process. After the specified number of failure attempts, the connection will be automatically dropped by the server process.
Not D: REMOTE_LOGIN_PASSWORDFILE specifies whether Oracle checks for a password file.
Values:
shared
One or more databases can use the password file. The password file can contain SYS as well as non-SYS users.
exclusive
The password file can be used by only one database. The password file can contain SYS as well as non-SYS users.
none
Oracle ignores any password file. Therefore, privileged users must be authenticated by the operating system.
Note:
The REMOTE_OS_AUTHENT parameter is deprecated. It is retained for backward compatibility only.

NEW QUESTION 118
Your multitenant container database (CDB) contains some pluggable databases (PDBs), you execute the following command in the root container:

Which two statements are true? (Choose two.)

A. The C # # A_ADMIN user will be able to use the TEMP_TS temporary tablespace only in root.
B. The command will, create a common user whose description is contained in the root and each PDB.
C. The command will create a user in the root container only because the container clause is not used.
D. The schema for the common user C # # A_ADMIN can be different in each container.
E. Schema objects owned by the C# # A_ADMIN common user can be shared across all PDBs.

Answer: B,D

NEW QUESTION 119
You are about to plug a multi-terabyte non-CDB into an existing multitenant container database (CDB).
The characteristics of the non-CDB are as follows:
-Version: Oracle Database 11g Release 2 (11.2.0.2.0) 64-bit -Character set: AL32UTF8 -National character set: AL16UTF16 -O/S: Oracle Linux 6 64-bit
The characteristics of the CDB are as follows:
-Version: Oracle Database 12c Release 1 64-bit -Character Set: AL32UTF8 -National character set: AL16UTF16 -O/S: Oracle Linux 6 64-bit
Which technique should you use to minimize down time while plugging this non-CDB into the CDB?

A. Data Pump full export/import
B. The DBMS_PDB package
C. Transportable tablespace
D. RMAN
E. Transportable database

Answer: C

Explanation:
* Overview, example:
-Log into ncdb12c as sys
-Get the database in a consistent state by shutting it down cleanly.
-Open the database in read only mode
-Run DBMS_PDB.DESCRIBE to create an XML file describing the database.
-Shut down ncdb12c
-Connect to target CDB (CDB2)
-Check whether non-cdb (NCDB12c) can be plugged into CDB(CDB2)
-Plug-in Non-CDB (NCDB12c) as PDB(NCDB12c) into target CDB(CDB2).
-Access the PDB and run the noncdb_to_pdb.sql script.
-Open the new PDB in read/write mode.
*You can easily plug an Oracle Database 12c non-CDB into a CDB. Just create a PDB manifest file for the non-CDB, and then use the manifest file to create a cloned PDB in the CDB.
*Note that to plugin a non-CDB database into a CDB, the non-CDB database needs to be of version 12c as well. So existing 11g databases will need to be upgraded to 12c before they can be part of a 12c CDB.

NEW QUESTION 120
On your Oracle Database, you issue the following commands to create indexes:
SQL > CREATE INDEX oe.ord_customer_ix1 ON oe.orders (customer_id, sales_rep_id) INVISIBLE; SQL> CREATE BITMAP INDEX oe.ord_customer_ix2 ON oe.orders (customer_id, sales_rep_id); Which two statements are true? (Choose two.)

A. The ORD_CUSTOMER_IX1 index is not used by the optimizer even when the OPTIMIZER_USE_INVISIBLE_INDEXES parameters is set to true.
B. Only the ORD_CUSTOMER_IX1 index created.
C. Both the indexes are updated when a row is inserted, updated, or deleted in the ORDERS table.
D. Both the indexes are created: however, only ORD_CUSTOMERS_IX2 is used by the optimizer for queries on the ORDERS table.
E. Both the indexes are created: however, only ORD_CUSTOMERS_IX1 is used by the optimizer for queries on the ORDERS table.
F. Both the indexes are created and used by the optimizer for queries on the ORDERS table.

Answer: C,D

Explanation:
Explanation
Not A: Both indexes are created fine.
B: The invisible index ORD_CUSTOMERS_IX1 and the bitmap index are both updated by DML operations on the Orders table.
F: Since ORD_CUSTOMERS_IX1 is invisible only ORD_CUSTOMERS_IX2 is used by the query optimizer.
Not C, Not D, Not E:
* ord_customer_ix1 is an invisible index and is therefore not used by the optimizer.
* VISIBLE | INVISIBLE Use this clause to specify whether the index is visible or invisible to the optimizer.
An invisible index is maintained by DML operations, but it is not be used by the optimizer during queries unless you explicitly set the parameter OPTIMIZER_USE_INVISIBLE_INDEXES to TRUE at the session or system level.
Note: Specify BITMAP to indicate that index is to be created with a bitmap for each distinct key, rather than indexing each row separately. Bitmap indexes store the rowids associated with a key value as a bitmap. Each bit in the bitmap corresponds to a possible rowid. If the bit is set, then it means that the row with the corresponding rowid contains the key value. The internal representation of bitmaps is best suited for applications with low levels of concurrent transactions, such as data warehousing.

NEW QUESTION 121
You are using RMAN to back up your database. All the data files are in read/write mode.
Examine the RMAN configuration parameters:

Which two statements are true about a whole consistent backup of a database running in ARCHIVELOG mode? (Choose two.)
