Demo Questions

Question 1
Your database is running an ARCHIVELOG mode. 
The following parameters are set in your database instance:

  

Which statement is true about the archived redo log files?

  • A: They are created only in the location specified by the LOG_ARCHIVE_DEST_1 parameter.
  • B: They are created only in the Fast Recovery Area because configuring the DB_RECOVERY_FILE_DEST and DB_RECOVERY_FILE_DEST_SIZE parameters automatically enables flashback for the database.
  • C: They are created in the location specified by the LOG_ARCHIVE_DEST_1 parameter and in the default location $ORACLE_HOME/dbs/arch.
  • D: They are created in the location specified by the LOG_ARCHIVE_DEST_1 parameter and in the location specified by the DB_RECOVERY_FILE_DEST parameter.



Question 2
Your multitenant container database (CDB) is running in ARCHIVELOG mode. You connect to the CDB RMAN. 
Examine the following command and its output:

  

You execute the following command:
RMAN > BACKUP DATABASE PLUS ARCHIVELOG; 
Which data files will be backed up?

  • A: Data files that belong to only the root container
  • B: Data files that belong to the root container and all the pluggable databases (PDBs)
  • C: Data files that belong to only the root container and PDB$SEED
  • D: Data files that belong to the root container and all the PDBs excluding PDB$SEED



Question 3
You are administering a database stored in Automatic Storage management (ASM). The files are stored in the DATA disk group. You execute the following command:

  

What is the result?

  • A: The file ‘+data.231.45678’ is physically relocated to ‘+data/prod’ and renamed as ‘myfile.dbf’.
  • B: The file ‘+data.231.45678’ is renamed as ‘myfile.dbf’, and copied to ‘+data/prod’.
  • C: The file ‘+data.231.45678’ remains in the same location and a synonym 'myfile.dbf' is created.
  • D: The file ‘myfile.dbf’ is created in ‘+data/prod’ and the reference to ‘+data.231.45678’ in the data dictionary removed.



Question 4
Which three functions are performed by the SQL Tuning Advisor?

  • A: Building and implementing SQL profiles
  • B: Recommending the optimization of materialized views
  • C: Checking query objects for missing and stale statistics
  • D: Recommending bitmap, function-based, and B-tree indexes
  • E: Recommending the restructuring of SQL queries that are using bad plans



Question 5
Examine the following command:
ALTER SYSTEM SET enable_ddl_logging=FALSE; 
Which statement is true?

  • A: None of the data definition language (DDL) statements are logged in the trace file.
  • B: Only DDL commands that resulted in errors are logged in the alert log file.
  • C: A new log.xml file that contains the DDL statements is created, and the DDL command details are removed from the alert log file.
  • D: Only DDL commands that resulted in the creation of new database files are logged.



Question 6
Your multitenant container database (CDB) contains three pluggable database (PDBs). You find that the control file is damaged. You plan to use RMAN to recover the control file. There are no startup triggers associated with the PDBs. 
Which three steps should you perform to recover the control file and make the database fully operational? (Choose three.)

  • A: Mount the container database (CDB) and restore the control file from the control file autobackup.
  • B: Recover and open the CDB in NORMAL mode.
  • C: Mount the CDB and then recover and open the database, with the RESETLOGS option.
  • D: Open all the pluggable databases.
  • E: Recover each pluggable database.
  • F: Start the database instance in the nomount stage and restore the control file from control file autobackup.



Question 7
A new report process containing a complex query is written, with high impact on the database. You want to collect basic statistics about query, such as the level of parallelism, total database time, and the number of I/O requests. 
For the database instance STATISTICS_LEVEL, the initialization parameter is set to TYPICAL and the CONTROL_MANAGEMENT_PACK_ACCESS parameter is set to DIAGNOSTIC+TUNING. 
What should you do to accomplish this task?

  • A: Execute the query and view Active Session History (ASH) for information about the query.
  • B: Enable SQL trace for the query.
  • C: Create a database operation, execute the query, and use the DBMS_SQL_MONITOR.REPORT_SQL_MONITOR function to view the report.
  • D: Use the DBMS_APPLICATION_INFO.SET_SESSION_LONGOPS procedure to monitor query execution and view the information from the V$SESSION_LONGOPS view.



Question 8
Identify two valid options for adding a pluggable database (PDB) to an existing multitenant container database (CDB). (Choose two.)

  • A: Use the CREATE PLUGGABLE DATABASE statement to create a PDB using the files from the SEED.
  • B: Use the CREATE DATABASE ... ENABLE PLUGGABLE DATABASE statement to provision a PDB by copying file from the SEED.
  • C: Use the DBMS_PDB package to clone an existing PDB.
  • D: Use the DBMS_PDB package to plug an Oracle 12c non-CDB database into an existing CDB.
  • E: Use the DBMS_PDB package to plug an Oracle 11g Release 2 (11.2.0.3.0) non-CDB database into an existing CDB.



Question 9
Your database supports a DSS workload that involves the execution of complex queries: Currently, the library cache contains the ideal workload for analysis. You want to analyze some of the queries for an application that are cached in the library cache.
What must you do to receive recommendations about the efficient use of indexes and materialized views to improve query performance?

  • A: Create a SQL Tuning Set (STS) that contains the queries cached in the library cache and run the SQL Tuning Advisor (STA) on the workload captured in the STS.
  • B: Run the Automatic Workload Repository (AWR) report.
  • C: Create an STS that contains the queries cached in the library cache and run the SQL Performance Analyzer (SPA) on the workload captured in the STS.
  • D: Create an STS that contains the queries cached in the library cache and run the SQL Access Advisor on the workload captured in the STS.
  • E: Run the Automatic Database Diagnostic Monitor (ADDM).



Question 10
The following parameters are set for your Oracle 12c database instance:

  

You want to manage the SQL plan evolution task manually. Examine the following steps:
Set the evolve task parameters. 
Create the evolve task by using the DBMS_SPM.CREATE_EVOLVE_TASK function. 
Implement the recommendations in the task by using the DBMS_SPM.IMPLEMENT_EVOLVE_TASK function. 
Execute the evolve task by using the DBMS_SPM.EXECUTE_EVOLVE_TASK function. 
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
