Demo Questions

Question 1
Which three are true about the large pool for an Oracle database instance that supports shared server connections? 

  • A: Allocates memory for RMAN backup and restore operations
  • B: Allocates memory for shared and private SQL areas
  • C: Contains a cursor area for storing runtime information about cursors
  • D: Contains stack space
  • E: Contains a hash area performing hash joins of tables



Question 2
What are three purposes of the RMAN “FROM” clause?

  • A: to support PUSH-based active database duplication
  • B: to support synchronization of a standby database with the primary database in a Data environment
  • C: to support PULL-based active database duplication
  • D: to support file restores over the network in a Data Guard environment
  • E: to support file recovery over the network in a Data Guard environment



Question 3
You plan to use the In-Database Archiving feature of Oracle Database 12c, and store rows that are inactive for over three months, in Hybrid Columnar Compressed (HCC) format. 
Which three storage options support the use of HCC? (Choose three.) 

  • A: ASM disk groups with ASM disks consisting of Exadata Grid Disks.
  • B: ASM disk groups with ASM disks consisting of LUNs on any Storage Area Network array
  • C: ASM disk groups with ASM disks consisting of any zero-padded NFS-mounted files
  • D: Database files stored in ZFS and accessed using conventional NFS mounts.
  • E: Database files stored in ZFS and accessed using the Oracle Direct NFS feature
  • F: Database files stored in any file system and accessed using the Oracle Direct NFS feature
  • G: ASM disk groups with ASM disks consisting of LUNs on Pillar Axiom Storage arrays



Question 4
In your multitenant container database (CDB) containing pluggable databases (PDB), users complain about performance degradation. 
How does real-time Automatic Database Diagnostic Monitor (ADDM) check performance degradation and provide solutions?

  • A: It collects data from SGA and compares it with a preserved snapshot.
  • B: It collects data from SGA, analyzes it, and provides a report.
  • C: It collects data from SGA and compares it with the latest snapshot.
  • D: It collects data from both SGA and PGA, analyzes it, and provides a report.



Question 5
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 6
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 7
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 8
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 9
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 10
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.
