D. Two or more tables cannot have keys generated from the same sequence.
E. A sequence can only be dropped by a DBA.
F. A sequence number that was allocated can be rolled back if a transaction fails.
Correct Answer: BCD
Question 2:
Which two statements are true regarding a SAVEPOINT? (Choose two.)
A. Rolling back to a SAVEPOINT can undo a CREATE INDEX statement
B. Rolling back to a SAVEPOINT can undo a TRUNCATE statement
C. Only one SAVEPOINT may be issued in a transaction
D. A SAVEPOINT does not issue a COMMIT
E. Rolling back to a SAVEPOINT can undo a DELETE statement
Correct Answer: DE
Question 3:
Which three functions are performed by dispatchers in a shared server configuration? (Choose three.)
A. writing inbound requests to the common request queue from all shared server connections
B. checking for outbound shared server responses on the common outbound response queue
C. receiving inbound requests from processes using shared server connections
D. sending each connection input request to the appropriate shared server input queue
E. broadcasting shared server session responses back to requesters on all connections
F. sending shared server session responses back to requesters on the appropriate connection
Correct Answer: ACF
Ref: https://docs.oracle.com/cd/B28359_01/server.111/b28310/manproc001.htm#ADMIN11168 An ***idle shared server process picks up*** the virtual circuit from the common queue
Question 4:
A database is configured to use automatic undo management with temporary undo enabled.
An UPDATE is executed on a temporary table.
Where is the UNDO stored?
A. in the undo tablespace
B. in the SYSAUX tablespace
C. in the SGA
D. in the PGA
E. in the temporary tablespace
Correct Answer: E
Oracle database 12c Release 1 (12.1) introduced the concept of temporary undo, allowing the undo segments for global temporary tables to be stored in the temporary tablespace. This allows global temporary tables to be used in physical standby databases and read-only databases, as well as removing the need to create a redo.
16.7 Managing Temporary Undo By default, undo records for temporary tables are stored in the undo tablespace and are logged in the redo, which is the same way undo is managed for persistent tables. However, you can use the TEMP_UNDO_ENABLED initialization parameter to separate undo for temporary tables from undo for persistent tables. When this parameter is set to TRUE, the undo for temporary tables is called temporary undo.
16.7.1 About Managing Temporary Undo Temporary undo records are stored in the database\’s temporary tablespaces and thus are not logged in the redo log. When temporary undo is enabled, some of the segments used by the temporary tablespaces store the temporary undo, and these segments are called temporary undo segments.
Reference: http://www.dba-oracle.com/t_temp_undo_enabled.htm Reference: https://docs.oracle.com/database/121/ADMIN/undo.htm#ADMIN11479
Question 5:
Which two statements are true about the configuration and use of UNDO_RETENTION with GUARANTEED RETENTION? (Choose two.)
A. UNDO_RETENTION specifies for how long Oracle attempts to keep expired and unexpired UNDO.
B. UNDO_RETENTION specifies how long all types of UNDO are retained.
C. Unexpired UNDO is always retained.
D. Active UNDO is always retained.
E. UNDO_RETENTION specifies for how long Oracle attempts to keep unexpired UNDO.
Correct Answer: CD
By definition, undo extents that still have to overlive the retention period are unexpired. So, when undo_retention is set and retention is guaranteed, unexpired undo is always retained.
As opposed to the case in which retention is no guarantee, where also unexpired extents can be overwritten IF and when needed.
In this particular case, so, I would say C-D is the correct answer.
Question 6:
Which two statements are true about the PMON background process? (Choose two.)
A. It registers database services with all local and remote listeners known to the database instance
B. It frees resources held by abnormally terminated processes
C. It records checkpoint information in the control file
D. It frees unused temporary segments
E. It kills sessions that exceed the idle time
Correct Answer: BE
Reference: https://docs.oracle.com/cd/B19306_01/server.102/b14220/process.htm
Performs process recovery when a user process fails Cleans up the database buffer cache Frees resources that are used by the user process Monitors sessions for idle session timeout
Question 7:
The ORCL database has RESUMABLE__TIMEOUT = 7200 and DEFERRED_SEGMENT_CREATION = FALSE
User U1 has a 1 MB quota in tablespace DATA.
U1 executes this command:
SQL> CREATE TABLE t1 AS
(SELECT object_name, sharing, created
FROM dba_objects);
U1 complains that the command is taking too long to execute.
In the alert log, the database administrator (DBA) finds this:
2017-03-06T12:15:17.183438+05:30
statement in resumable session `User U1(136), Session 1, Instance 1\’ was suspended due to ORA-01536: space quota exceeded for tablespace `DATA\’
Which are three actions any one of which the DBA could take to resume the session? (Choose three.)
A. Add a data file to DATA
B. Drop other U1 objects in DATA
C. Increase U1\’s quota sufficiently in DATA
D. Set DEFERRED_SEGMENT_CREATION to TRUE
E. Grant UNLIMITED TABLESPACE to U1
F. Set AUTOEXTEND ON for data files in DATA
Correct Answer: BCE
Set DEFERRED_SEGMENT_CREATION to TRUE, when creating the table you are already inserting rows as select, therefore the segment has already been created the D is not. Configure Set AUTOEXTEND ON for data files in DATA, if you have 1M quota it will not work.
A. Add a data file to DATA — n’t help as the problem is quota to the user, not the space
B. Drop other U1 objects in DATA — Will help as it will reduce the used space from the quota for that user
C. Increase U1\’s quota sufficiently in DATA — Will help.
D. Set DEFERRED_SEGMENT_CREATION to TRUE — n’t help, segments have to be created as its CTAS
E. Grant UNLIMITED TABLESPACE to U1 — Will help.
F. Set AUTOEXTEND ON for data files in DATA — n’t help as the problem is a quota to the user, not the space
Question 8:
Which three statements are true about table data storage in an Oracle Database? (Choose three.)
A. Data block headers contain their own Data Block Address (DBA)
B. A table row piece can be chained across several database blocks
C. Multiple row pieces from the same row may be stored in different database blocks
D. Multiple row pieces from the same row may be stored in the same block
E. Data block-free space is always contiguous in the middle of the block
F. Index block-free space is always contiguous in the middle of the block
Correct Answer: ABC
Question 9:
Which two statements are true about the DUAL table? (Choose two.)
A. It can be accessed only by the SYS user
B. It consists of a single row and single column of VARCHAR2 data type
C. It can display multiple rows but only a single column
D. It can be used to display only constants or pseudo columns
E. It can be accessed by any user who has the SELECT privilege in any schema
F. It can display multiple rows and columns
Correct Answer: BF
SQL> SELECT level, sysdate 2 FROM dual 3 CONNECT BY 4 level <= 4;
LEVEL SYSTEM
1 06-AUG-20
2 06-AUG-20
3 06-AUG-20
4 06-AUG-20
It can return multiple rows and columns.
D is wrong, you just create a brand new user and do not grant any privilege but still, it can select dual table.
Reference: https://en.wikipedia.org/wiki/DUAL_table
Question 10:
Which two statements are true about User Authentication in an Oracle Database?
A. Operating System authentication may be used for system-privileged administrative users.
B. REKOTE_LOGIN_PASSMOREFiLE must be set to exclusive to permit password changes for system-privileged administrative users.
C. Password authentication must be used for system-privileged administrative users.
D. Password File authentication must be used for system-privileged administrative users.
E. Password File authentication is supported for any type of database user.
Correct Answer: AC
Question 11:
Your database instance is started with a PFILE.
Examine these parameters:
You want to increase the size of the buffer cache.
Free memory is available to increase the size of the buffer cache.
You execute the command:
SQL> ALTER SYSTEM SET DB_CACHE_SIZE=1024M;
What is the outcome?
A. The value is changed only in the PFILE and takes effect at the next instance startup
B. The value is changed for the current instance and in the PFILE
C. It fails because the SCOPE clause is missing
D. Change is applied to the current instance but does not persist after the instance restart
Correct Answer: D
The change is applied in memory only, the change does not persist as the database can\’t write to the file
The default SCOPE option, when you start the instance using a PFILE, is MEMORY (as well as the only scope option you can use with a file). If scope is omitted the default scope option is used instead. The SCOPE clause is optional and
not mandatory when changing the value of a parameter!
A is wrong, as the file is a read-only file for the database so it can’t write to it. Changes to the file have to be done manually by changing it directly using f.e. vi on Unix systems.
B is wrong, same reason as for why answer A is wrong
C is wrong, as mentioned above, when omitted the scope clause defaults to MEMORY when using a file.
Not related to that question but the more you know: When starting the database using a spfile you have three options for the scope (MEMORY, SPFILE, and BOTH). The default value is BOTH.
Reference: https://docs.oracle.com/database/121/SQLRF/statements_2017.htm#SQLRF00902
Question 12:
Your database instance was shut down normally and then started in the NOMOUNT state. You then execute this command:
ALTER DATABASE MOUNT;
Which two actions are performed? (Choose two.)
A. The online redo logs are opened
B. The online data files are opened
C. The alert log records the execution details
D. The Oracle background processes are started
E. The initialization parameter file is read
F. The control file is read
Correct Answer: CF

Question 13:
Which three statements are true about the naming methods and their features supported by the Oracle database used to resolve connection information?
A. Local naming can be used if Connect-Time Failover Is required.
B. A client can connect to an Oracle database instance even If no client-side network admin has been configured.
C. Directory Naming requires setting the TNS_ADMIN environment variable on the client side.
D. Local Naming requires setting the TNS_ADMIN environment variable on the client side.
E. Directory Naming can be used if Connect-Time Failover is required.
F. Easy Connect supports TCP/IP and SSL.
Correct Answer: ABC
Question 14:
You have been tasked to create a table for a banking application.
One of the columns must meet three requirements:
Be stored in a format supporting date arithmetic without using conversion functions
Store a loan period of up to 10 years
Be used for calculating interest for the number of days the loan remains unpaid
Which data type should you use?
A. INTERVAL YEAR TO MONTH
B. INTERVAL DAY TO SECOND
C. TIMESTAMP WITH LOCAL TIMEZONE
D. TIMESTAMP
E. TIMESTAMP WITH TIMEZONE
Correct Answer: B
Since the third requirement for banking application is
\’Be used for calculating interest for the number of days the loan remains unpaid\’
So, Data Type \’INTERVAL DAY TO SECOND\’ must be used to calculate the duration in several days.
Question 15:
Examine this SQL statement:
SELECT cust_id, cust_last_name “Last Name” FROM customers WHERE country_id = 10 UNION SELECT cust_id CUST_NO, cust_last_name FROM customers WHERE country_id = 30
Identify three ORDER BY clauses, any one of which can complete the query successfully. (Choose three.)
A. ORDER BY “Last Name”
B. ORDER BY 2, 1
C. ORDER BY 2, cust_id
D. ORDER BY CUST_NO
E. ORDER BY “CUST_NO”
Correct Answer: ABC
