1.Which two tasks can be performed by using Oracle SQL statements?
A. changing the password for an existing database
B. connecting to a database instance
C. querying data from tables across databases
D. starting up a database instance
E. executing operating system (OS) commands in a session
Answer: C,E

2.Which statement is true regarding external tables?
A. The default REJECT LIMIT for external tables is UNLIMITED.
B. The data and metadata for an external table are stored outside the database.
C. ORACLE_LOADER and ORACLE_DATAPUMP have exactly the same functionality when used with an
external table.
D. The CREATE TABLE AS SELECT statement can be used to unload data into regular table in the
database from an external table.
Answer: D

3.Which two statements are true about sequences created in a single instance database? (Choose two.)
A. CURRVAL is used to refer to the last sequence number that has been generated
B. DELETE <sequencename> would remove a sequence from the database
C. The numbers generated by a sequence can be used only for one table
D. When the MAXVALUE limit for a sequence is reached, you can increase the MAXVALUE limit by using
the ALTER SEQUENCE statement
E. When a database instance shuts down abnormally, the sequence numbers that have been cached but
not used would be available once again when the database instance is restarted
Answer: A,D
Explanation: Gaps in the Sequence
Although sequence generators issue sequential numbers without gaps, this action occurs independent of
a commit or rollback. Therefore, if you roll back a statement containing a sequence, the number is lost.
Another event that can cause gaps in the sequence is a system crash. If the sequence caches values in
memory, those values are lost if the system crashes. Because sequences are not tied directly to tables,
the same sequence can be used for multiple tables. However, if you do so, each table can contain gaps in
the sequential numbers.
Modifying a Sequence
If you reach the MAXVALUE limit for your sequence, no additional values from the sequence are allocated
and you will receive an error indicating that the sequence exceeds the MAXVALUE. To continue to use
the sequence, you can modify it by using the ALTER SEQUENCE statement To remove a sequence, use
the DROP statement:
DROP SEQUENCE dept_deptid_seq;
