Q4. 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: C,E
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'.
Q5. You execute the commands on a multitenant container database CDB1 that has multiple pluggable databases:
$ . oraenv ORACLE-_SID = [oracle] ? cdb1 The oraclebasefor ORACLE_HOME=/u01/app/oracle/product/12.1.0/dbhome_1 is
/u01/app/oracle $ rman target / Recovery Manager : Release 12.1.0.0.2 - production on Fri Ju1 19 05:18:33: 2013

RMAN>SELECT name FROMv$tablespace;
Which statement is true about the execution of the last command?
A. It succeeds and displays all the tablespaces that belong to the root database.
B. It fails and returns an error because a connection is not made by using the sysdba privilege.
C. It succeeds and displays all the tablespaces that belong to the root and pluggable databases.
D. It fails and returns an error because SQL commands cannot be executed at the RMAN prompt.
Answer: A
Q6. 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:
: r-ar.
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:.
Answer: B
Q7. You want to capture column group usage and gather extended statistics for better cardinality estimates for the customers table in the SH schema.
Examine the following steps:
1. Issue the SELECTDBMS_STATS. CREATE_EXTENDED_STATS(‘SH’, 'CUSTOMERS')from dual statement.
2.Execute the dbms_stats.seed_col_usage (null,‘SH’,500) procedure. 3.Execute the required queries on the customers table.
4.Issue the select dbms_stats.reportwcol_usage(‘SH’, 'customers') from dual statement.
Identify the correct sequence of steps.
A. 3, 2, 1, 4
B. 2, 3, 4, 1
C. 4, 1, 3, 2
D. 3, 2, 4, 1
Answer: B
Explanation: Step 1 (2). Seed column usage Oracle must observe a representative workload, in order to determine the appropriate column groups. Using the new procedure DBMS_STATS.SEED_COL_USAGE, you tell Oracle how long it should observe the workload. Step 2: (3)You don't need to execute all of the queries in your work during this window. You can simply run explain plan for some of your longer running queries to ensure column group information is recorded for these queries. Step 3. (1) Create the column groups Atthis point you can get Oracle to automatically create the column groups for each of the tables based on the usage information captured during the monitoring window. You simply have to call the DBMS_STATS.CREATE_EXTENDED_STATS function for each table.This function requires just two arguments, the schema name and the table name. From then on, statistics will be maintained for each column group whenever statistics are gathered on the table.
Note:
*
DBMS_STATS.REPORT_COL_USAGE reports column usage informationand records all
the SQL operations the database has processed for a given object.
*
The Oracle SQL optimizer has always been ignorant of the implied relationships between
data columns within the same table. While the optimizer has traditionally analyzedthe
distribution of values within a column, he does not collect value-based relationships
between columns.
*
Creating extended statistics
Here are the steps to create extended statistics for related table columns
withdbms_stats.created_extended_stats:
1 -The first step is to create column histograms for the related columns.
2 – Next, we run dbms_stats.create_extended_stats to relate the columns together. Unlike a traditional procedure that is invoked via an execute (“exec”) statement, Oracle extended statistics are created via a select statement.
Q8. You wish to enable an audit policy for all database users, except sys, system, and scott. You issue the following statements:
SQL> AUDIT POLICY ORA_DATABASE_PARAMETER EXCEPT SYS;
SQL> AUDIT POLICY ORA_DATABASE_PARAMETER EXCEPT SYSTEM;
SQL> AUDIT POLICY ORA_DATABASE_PARAMETER EXCEPT SCOTT;
For which database users is the audit policy now active?
A. all users exceptsys
B. all users except scott
C. all users except sys and scott
D. all users except sys, system, and scott
Answer: B
Q9. Examine the RMAN command:
RMAN> CONFIGURE ENCRYPTION FOR DATABASE ON;
RMAN> BACKUP DATABASE PLUS ARCHIVELOG;
Which prerequisitemust be met before accomplishing the backup?
A. The password for the encryption must be set up.
B. Oracle wallet for the encryption must be set up.
C. All the tablespaces in the database must be encrypted.
D. Oracle Database Vault must be enabled.
Answer: B
Reference:configuration encryption will use by Transparent encryption, For transparent encryption, you will need to create a wallet, and it must be open.
Transparent encryption will then occur automatically after you have issued the CONFIGURE ENCRYPTION FOR DATABASE ON or CONFIGURE ENCRYPTION FOR TABLESPACE ON command.
