Demo Questions

Question 1
Which three statements are true about Automatic Workload Repository (AWR)? (Choose three.)

  • A: All AWR tables belong to the SYSTEM schema.
  • B: The AWR data is stored in memory and in the database.
  • C: The snapshots collected by AWR are used by the self-tuning components in the database
  • D: AWR computes time model statistics based on time usage for activities, which are displayed in the v$SYS time model and V$SESS_TIME_MODEL views.
  • E: AWR contains system wide tracing and logging information.



Question 2
You upgraded your database from pre-12c to a multitenant container database (CDB) containing pluggable databases (PDBs). 
Examine the query and its output:

  

Which two tasks must you perform to add users with SYSBACKUP, SYSDG, and SYSKM privilege to the password file? (Choose two.)

  • A: Assign the appropriate operating system groups to SYSBACKUP, SYSDG, SYSKM.
  • B: Grant SYSBACKUP, SYSDG, and SYSKM privileges to the intended users.
  • C: Re-create the password file with SYSBACKUP, SYSDG, and SYSKM privilege and the FORCE argument set to No.
  • D: Re-create the password file with SYSBACKUP, SYSDG, and SYSKM privilege, and FORCE arguments set to Yes.
  • E: Re-create the password file in the Oracle Database 12c format.



Question 3
An application accesses a small lookup table frequently. You notice that the required data blocks are getting aged out of the default buffer cache. 
How would you guarantee that the blocks for the table never age out?

  • A: Configure the KEEP buffer pool and alter the table with the corresponding storage clause.
  • B: Increase the database buffer cache size.
  • C: Configure the RECYCLE buffer pool and alter the table with the corresponding storage clause.
  • D: Configure Automata Shared Memory Management.
  • E: Configure Automatic Memory Management.



Question 4
You conned using SQL Plus to the root container of a multitenant container database (CDB) with SYSDBA privilege. 
The CDB has several pluggable databases (PDBs) open in the read/write mode. 
There are ongoing transactions in both the CDB and PDBs. 
What happens alter issuing the SHUTDOWN TRANSACTIONAL statement?

  • A: The shutdown proceeds immediately. The shutdown proceeds as soon as all transactions in the PDBs are either committed or rolled hack.
  • B: The shutdown proceeds as soon as all transactions in the CDB are either committed or rolled back.
  • C: The shutdown proceeds as soon as all transactions in both the CDB and PDBs are either committed or rolled back.
  • D: The statement results in an error because there are open PDBs.



Question 5
You are planning the creation of a new multitenant container database (CDB) and want to store the ROOT and SEED container data files in separate directories. 
You plan to create the database using SQL statements. 
Which three techniques can you use to achieve this? (Choose three.)

  • A: Use Oracle Managed Files (OMF).
  • B: Specify the SEED FILE_NAME_CONVERT clause.
  • C: Specify the PDB_FILE_NAME_CONVERT initialization parameter.
  • D: Specify the DB_FILE_NAMECONVERT initialization parameter.
  • E: Specify all files in the CREATE DATABASE statement without using Oracle managed Files (OMF).



Question 6
You are about to plug a multi-terabyte non-CDB into an existing multitenant container database (CDB). 
The characteristics of the non-CDB are as follows:
Version: Oracle Database 11g Release 2 (11.2.0.2.0) 64-bit
Character set: AL32UTF8
National character set: AL16UTF16
O/S: Oracle Linux 6 64-bit
The characteristics of the CDB are as follows:
Version: Oracle Database 12c Release 1 64-bit
Character Set: AL32UTF8
National character set: AL16UTF16
O/S: Oracle Linux 6 64-bit
Which technique should you use to minimize down time while plugging this non-CDB into the CDB?

  • A: Transportable database
  • B: Transportable tablespace
  • C: Data Pump full export/import
  • D: The DBMS_PDB package
  • E: RMAN



Question 7
Your database supports an online transaction processing (OLTP) application. The application is undergoing some major schema changes, such as addition of new indexes and materialized views. You want to check the impact of these changes on workload performance. 
What should you use to achieve this?

  • A: Database replay
  • B: SQL Tuning Advisor
  • C: SQL Access Advisor
  • D: SQL Performance Analyzer
  • E: Automatic Workload Repository compare reports



Question 8
An administrator account is granted the CREATE SESSION and SET CONTAINER system privileges. 
A multitenant container database (CDB) instant has the following parameter set:
THREADED_EXECUTION = FALSE 
Which four statements are true about this administrator establishing connections to root in a CDB that has been opened in read only mode? (Choose four.)

  • A: You can connect as a common user by using the connect statement.
  • B: You can connect as a local user by using the connect statement.
  • C: You can connect by using easy connect.
  • D: You can connect by using OS authentication.
  • E: You can connect by using a Net Service name.
  • F: You can connect as a local user by using the SET CONTAINER statement.



Question 9
Examine the following query output:

  

You issue the following command to import tables into the hr schema:
$ > impdp hr/hr directory = dumpdir dumpfile = hr_new.dmp schemas=hr TRANSFORM=DISABLE_ARCHIVE_LOGGING: Y
Which statement is true?

  • A: All database operations performed by the impdp command are logged.
  • B: Only CREATE INDEX and CREATE TABLE statements generated by the import are logged.
  • C: Only CREATE TABLE and ALTER TABLE statements generated by the import are logged.
  • D: None of the operations against the master table used by Oracle Data Pump to coordinate its activities are logged.



Question 10
You notice a performance change in your production Oracle database and you want to know which change has made this performance difference. 
You generate the Compare Period Automatic Database Diagnostic Monitor (ADDM) report to further investigation. 
Which three findings would you get from the report? (Choose three.)

  • A: It detects any configuration change that caused a performance difference in both time periods.
  • B: It identifies any workload change that caused a performance difference in both time periods.
  • C: It detects the top wait events causing performance degradation.
  • D: It shows the resource usage for CPU, memory, and I/O in both time periods.
  • E: It shows the difference in the size of memory pools in both time periods.
  • F: It gives information about statistics collection in both time periods.
