Question 14

The following parameter are set for your Oracle 12c database instance: OPTIMIZER_CAPTURE_SQL_PLAN_BASELINES=FALSE OPTIMIZER_USE_SQL_PLAN_BASELINES=TRUE
You want to manage the SQL plan evolution task manually. Examine the following steps:
1. Set the evolve task parameters.
2. Create the evolve task by using the DBMS_SPM.CREATE_EVOLVE_TASK function.
3. Implement the recommendations in the task by using the DBMS_SPM.IMPLEMENT_EVOLVE_TASK function.
4. Execute the evolve task by using the DBMS_SPM.EXECUTE_EVOLVE_TASK function.
5. Report the task outcome by using the DBMS_SPM.REPORT_EVOLVE_TASK function. Identify the correct sequence of steps:

A. 2, 4, 5

B. 2, 1, 4, 3, 5

C. 1, 2, 3, 4, 5

D. 1, 2, 4, 5

Correct Answer:B
* Evolving SQL Plan Baselines

*2. Create the evolve task by using the DBMS_SPM.CREATE_EVOLVE_TASK function.
This function creates an advisor task to prepare the plan evolution of one or more plans for a specified SQL statement. The input parameters can be a SQL handle, plan name or a list of plan names, time limit, task name, and description.
1. Set the evolve task parameters. SET_EVOLVE_TASK_PARAMETER
This function updates the value of an evolve task parameter. In this release, the only valid parameter is TIME_LIMIT.
4. Execute the evolve task by using the DBMS_SPM.EXECUTE_EVOLVE_TASK function.
This function executes an evolution task. The input parameters can be the task name, execution name, and execution description. If not specified, the advisor generates the name, which is returned by the function.
3: IMPLEMENT_EVOLVE_TASK
This function implements all recommendations for an evolve task. Essentially, this function is equivalent to using ACCEPT_SQL_PLAN_BASELINE for all recommended plans. Input parameters include task name, plan name, owner name, and execution name.
5. Report the task outcome by using the DBMS_SPM_EVOLVE_TASK function.
This function displays the results of an evolve task as a CLOB. Input parameters include the task name and section of the report to include.

Question 15

You execute the following commands to audit database activities:
SQL > ALTER SYSTEM SET AUDIT_TRIAL=DB, EXTENDED SCOPE=SPFILE;
SQL > AUDIT SELECT TABLE, INSERT TABLE, DELETE TABLE BY JOHN By SESSION WHENEVER SUCCESSFUL;
Which statement is true about the audit record that generated when auditing after instance restarts?

A. One audit record is created for every successful execution of a SELECT, INSERT OR DELETE command on a table, and contains the SQL text for the SQL Statements.

B. One audit record is created for every successful execution of a SELECT, INSERT OR DELETE command, and contains the execution plan for the SQL statements.

C. One audit record is created for the whole session if john successfully executes a SELECT, INSERT, or DELETE command, and contains the execution plan for the SQL statements.

D. One audit record is created for the whole session if JOHN successfully executes a select command, and contains the SQL text and bind variables used.

E. One audit record is created for the whole session if john successfully executes a SELECT, INSERT, or DELETE command on a table, and contains the execution plan, SQL text, and bind variables used.

Correct Answer:A
Note:
* BY SESSION
In earlier releases, BY SESSION caused the database to write a single record for all SQL statements or operations of the same type executed on the same schema objects in the same session. Beginning with this release (11g) of Oracle Database, both BY SESSION and BY ACCESS cause Oracle Database to write one audit record for each audited statement and operation.
* BY ACCESS
Specify BY ACCESS if you want Oracle Database to write one record for each audited statement and operation. Note:
If you specify either a SQL statement shortcut or a system privilege that audits a data definition language (DDL) statement, then the database always audits by access. In all other cases, the database honors the BY SESSION or BY ACCESS specification.
* For each audited operation, Oracle Database produces an audit record containing this information:
/ The user performing the operation
/ The type of operation
/ The object involved in the operation
/ The date and time of the operation References:

Question 16

In your database, the STATISTICS_LEVEL parameter is set to TYPICAL and an Automatic Workload Repository (AWR) snapshot is taken every 30 minutes.
Which two statements are true about the Automatic Database Diagnostic Monitor (ADDM)? (Choose two.)

A. It measures database performance by analyzing the wait time and CPU time of all non-idle user sessions.

B. It always compares the latest snapshot with the baseline snapshot for analysis.

C. It runs after each AWR snapshot is created and it requires at least two snapshots for analysis.

D. It requires at least four AWR snapshots for analysis.

E. It calls other advisors if required, but does not provide recommendations about the advisors to be use

Question 18

You are administering a database stored in Automatic Storage Management (ASM). You use RMAN to back up the database and the MD_BACKUP command to back up the ASM metadata regularly. You lost an ASM disk group DG1 due to hardware failure.
In which three ways can you re-create the lost disk group and restore the data? (Choose three.)

A. Use the MD_RESTORE command to restore metadata for an existing disk group by passing the existing disk group name as an input parameter and use RMAN to restore the data.

B. Use the MKDG command to restore the disk group with the same configuration as the backed-up disk group and data on the disk group.

C. Use the MD_RESTORE command to restore the disk group with the changed disk group specification, failure group specification, name, and other attributes and use RMAN to restore the data.

D. Use the MKDG command to restore the disk group with the same configuration as the backed-up disk group name and same set of disks and failure group configuration, and use RMAN to restore the data.

E. Use the MD_RESTORE command to restore both the metadata and data for the failed disk group.

F. Use the MKDG command to add a new disk group DG1 with the same or different specifications for failure group and other attributes and use RMAN to restore the data.

Correct Answer:ACF
AC (not E):
The md_restore command allows you to restore a disk group from the metadata created by the md_backup command. md_restore can’t restore data, only metadata.
