A. when the tablespace is online
B. when the tablespace has segments with data in it
C. when the tablespace is a default permanent tablespace for the database
D. when the tablespace contains a table that is currently being used by transactions

E. It allows the data manipulation on the table using INSERT/UPDATE/DELETE SQL statements.
Q3. View the Exhibit and examine the undo tablespace attributes. Your database instance is experiencing a large volume of transactions from non-DBA users in the last one hour. The undo tablespace NDOTBS1 is full with transactions and no transaction was committed more than one hour ago. The database has two more undo tablespaces.
What happens to the new DML operations in this scenario?
A. The DML commands will fail
B. The undo data generated by the DML is stored in one of the two other undo tablespace
C. The undo data generated by the DML will overwrite the extents that contain committed undo data
D. The undo data generated by the DML is stored in the SYSTEM undo segment of the SYSTEM tablespace
Q4. SQL> AUDIT DROP ANY TABLE BY scott BY SESSION WHENEVER SUCCESSFUL;
What is the effect of this command?
A. One audit record is created for every successful DROP TABLE command executed in the session of SCOTT
B. One audit record is generated for the session when SCOTT grants the DROP ANY TABLE privilege to other users
C. One audit record is created for the whole session if user SCOTT successfully drops one or more tables in his session
D. One audit record is created for every session of any other user in which a table owned by SCOTT is dropped successfully
E. One audit record is created for every successful DROP TABLE command executed by any user to drop tables owned by SCOTT

B. You must configure the Flash Recovery Area (FRA) for the database.
C. You can perform complete database backups without closing the database.
D. All the previous closed database backups including control files become invalid afteryou configure the database to ARCHIVELOG mode.
Q6. View the Exhibit and examine the parameters. User A executes the following command to update the TRANS table:
SQL> UPDATE B.trans SET tr_amt=tr_amt+500 WHERE c_code='C005'
Before user A issues a COMMIT or ROLLBACK command, user B executes the following command on the TRANS table:
SQL> ALTER TABLE trans MODIFY (tr_type VARCHAR2(3));
What would happen in this scenario?
A. The ALTER TABLE command modifies the column successfully
B. The DDL operation gets higher priority and transaction for user A is rolled back
C. The ALETER TABLE command waits indefinitely until user A ends the transaction
D. The ALTER TABLE command fails after waiting for 60 seconds due to the resource being busy
Q7. You are managing an Oracle Database 11g database with the following backup strategy:
1. On Sunday, an incremental level 0 tape backup is performed
2. Monday through Saturday, a cumulative incremental level 1 tape backup is performed
Which two statements are true regarding the backups performed? (Choose two.)
A. The backup performed in step 1 backs up all blocks that have ever been in use in the database
B. The backup performed in step 2 copies all the blocks changed since the most recent level 0 backup
C. The backup performed in step 1 backs up all the blocks changed since the most recent level 1 backup
D. The backup performed in step 2 backs up all blocks that have changed since the most recent incremental backup at level 1
Q8. In which of the scenario will the DBA perform recovery? (Choose all that apply.)

( DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.156.24.216)(PORT = 1521))
(SERVER = DEDICATED)
(SERVICE_NAME = orcl.oracle.com)
The TNSPING command executes successfully when tested with ORCL, but you are not able to connect to the database instance with the following command:
SQL> CONNECT scott/tiger@orcl
What could be the reason for this?
A. The listener is not running on the database node.
B. The TNS_ADMIN environmental variable is set to a wrong value.
C. The orcl.oracle.com database service is not registered with the listener.
