NEW QUESTION 1
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 after the segments are moved
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. Taking the target tablespace offline after the segments are moved
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

The threshold for activating tiering policies is based on two parameters: TBS PERCENT USED
TBS PERCENT FREE
Both values can be controlled by the DBMS_ILM_ADMIN package.
TBS PERCENT USED and TBS PERCENT FREE default to 85 and 25, respectively. Hence, whenever the source tablespace’s usage percentage goes beyond 85 percent, any tiering policy specified on its
objects will be executed and objects will be moved to the target tablespace until the source tablespace becomes at least 25 percent free. Note that it is possible to add a custom condition to tiering policies to enable movement of data based on conditions other than how full the tablespace is.
In addition, the READ ONLY option must be explicitly specified for the target tablespace. 2021-04-01T21:59:00.56

NEW QUESTION 3
Examine the commands executed to monitor database operations:
$> conn sys/oracle@prod as sysdba SQL> VAR eid NUMBER
SQL>EXEC :eid := DBMS_SQL_MONITOR.BEGlN_OPERATION('batch_job’,FORCED_TRACKING=>'Y');
Which two statements are true?

A. Database operations will be monitored only when they consume a significant amount of resource.
B. Database operations for all sessions will be monitored.
C. Database operations will be monitored only if the STATISTICS_LEVEL parameter is set to TYPICAL and CONTROL_MANAGEMENT_PACK_ACCESS is set DIAGNISTIC + TUNING.
D. Only DML and DDL statements will be monitored for the session.
E. All subsequent statements in the session will be treated as one database operation and will be monitored.

Answer: CE

Explanation: C: Setting the CONTROL_MANAGEMENT_PACK_ACCESS initialization parameter to DIAGNOSTIC+TUNING (default) enables monitoring of database operations. Real-Time SQL Monitoring is a feature of the Oracle Database Tuning Pack.
Note:
* The DBMS_SQL_MONITOR package provides information about Real-time SQL Monitoring and
Real-time Database Operation Monitoring.
*(not B) BEGIN_OPERATION Function starts a composite database operation in the current session.
/ (E) FORCE_TRACKING - forces the composite database operation to be tracked when the operation starts. You can also use the string variable 'Y'.
/ (not A) NO_FORCE_TRACKING - the operation will be tracked only when it has consumed at least 5 seconds of CPU or I/O time. You can also use the string variable 'N'.

NEW QUESTION 4
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 http://docs.oracle.com/cd/B28359_01/backup.111/b28270/rcmreprt.htm#BRADV89585

NEW QUESTION 6
Consider the following scenario for your database:
-Backup optimization is enabled in RMAN.
-The recovery window is set to seven days in RMAN.
-The most recent backup to disk for the tools tablespace was taken on March 1, 2013.
-The tools tablespace is read-only since March 2, 2013.
On March 15, 2013, you issue the RMAN command to back up the database to disk. Which statement is true about the backup of the tools tablespace?

A. The RMAN backup fails because the tools tablespace is read-only.
B. RMAN skips the backup of the tools tablespace because backup optimization is enabled.
C. RMAN creates a backup of the tools tablespace because backup optimization is applicable only for the backups written to media.
D. RMAN creates a backup of the tools tablespace because no backup of the tablespace exists within the seven-day recovery window.

Answer: D

NEW QUESTION 7

Answer: B

NEW QUESTION 8
After implementing full Oracle Data Redaction, you change the default value for the number data type as follows:
SQL> SELECT NUMBER_VALUE FROM REDACTION_VALUES_FOR_TYPE_FULL; NUMBER_VALUE
------------------------- 0S
QL> EXEC DBMS_REDACT.UPDATE_FULL_REDACTI0N_VALUES(-1)
PL/SQL procedure successfully completed.
SQL> select number_value from redaction_values_for_type_full; NUMBER VALUE
------------------------
-1
After changing the value, you notice that FULL redaction continues to redact numeric data with a zero.
What must you do to activate the new default value for numeric full redaction?

A. Re-enable redaction policies that use FULL data redaction.
B. Re-create redaction policies that use FULL data redaction.
C. Re-connect the sessions that access objects with redaction policies defined on them.
D. Flush the shared pool.
E. Restart the database instanc

Answer: E

Explanation: About Altering the Default Full Data Redaction Value
You can alter the default displayed values for full Data Redaction polices. By default, 0 is the redacted value when Oracle Database performs full redaction (DBMS_REDACT.FULL) on a column of the NUMBER data type. If you want to change it to another value (for example, 7), then you can run the
DBMS_REDACT.UPDATE_FULL_REDACTION_VALUES procedure to modify this value. The modification applies to all of the Data Redaction policies in the current database instance. After you modify a
value, you must restart the database for it to take effect.

NEW QUESTION 9

C. You must take the tools01.dbf data file offline before you start a block media recovery.
D. You must put the database in NOARCHIVELOG mode to perform a block media recovery.
E. You can perform only a complete media recovery of individual blocks, point-in-time recovery of individual data blocks is not supported.

Answer: AE

NEW QUESTION 10
You want to back up a database such that only formatted blocks are backed up. Which statement is
true about this backup operation?

A. The backup must be performed in mount state.
B. The tablespace must be taken offline.
C. All files must be backed up as backup sets.
D. The database must be backed up as an image cop

Answer: A

Explanation: If you run multiple AUDIT statements on the same unified audit policy but specify different EXCEPT users, then Oracle Database uses the last exception user list, not any of the users from the preceding lists. This means the effect of the earlier AUDIT POLICY ... EXCEPT statements are overridden by the latest AUDIT POLICY ... EXCEPT statement https://docs.oracle.com/database/121/DBSEG/audit_config.htm#DBSEG459

NEW QUESTION 13
Which four actions are possible during an Online Datafile Move operation?

A. Creating and dropping tables in the datafile being moved
B. Performing file shrink of the data file being moved
C. Querying tables in the datafile being moved
D. Performing Block Media Recovery for a data block in the datafile being moved
E. Flashing back the database
F. Executing DML statements on objects stored in the datafile being moved

Answer: ACEF

Explanation: “The good news is that Oracle 12cR1 now offers the ability to move entire datafiles between different storage locations without ever having to take the datafiles offline. The datafiles being moved remain completely accessible to applications in almost all situations, including querying against or performing DML and DDL operations against existing objects, creating new objects, and even rebuilding indexes online. Online Move Datafile (OMD) also makes it possible to migrate a datafile between non-ASM and ASM storage (or vice-versa) while maintaining transparent application access to that datafile’s underlying database objects. OMD is completely compatible with online block media recovery, the automatic extension of a datafile, the modification of a tablespace between READ WRITE and READ ONLY mode, and it even permits backup operations to continue against any datafiles that are being moved via this feature.”

NEW QUESTION 14
Your multitenant container database (CDB) contains multiple pluggable databases (PDBs). You execute the command to create a common user:
SQL> CREATE USER c##a_admin IDENTIFIED BY password DEFAULT TABLESPACE users
QUOTA I00M ON users TEMPORARY TABLESPACE temp;
Which statement is true about the execution of the command?

A. The common user is created in the CDB and all the PDBs, and uses the users and temp tablespaces of the CDB to store schema objects.
B. The command succeeds only if all the PDBs have the users and temp tablespaces.
C. The command gives an error because the container=all clause is missing.
D. The command succeeds and sets the default permanent tablespace of a PDB as the default tablespace for the c##a_admin user if the users tabiespace does not exist in that PDB.

Answer: B

Explanation: When creating a common user, any tablespace, tablespace group or profile specified in the CREATE command must exist in every PDB. If none of these are specified, the default TABLESPACE, TEMPORARY TABLESPACE, and PROFILE for the PDB will be used.

NEW QUESTION 15
