You create a locally managed tablespace ORDERS_TBS with automatic segment management.
You then create the table DAILY_ORDS_LST in the ORDERS_TBS tablespace using the command.
CREATE TABLE daily_ords_1st(ordno NUMBER, ord_date DATE) PCTFREE 20;
How does the PCTFREE storage parameter influence data storage for this table?

• A. It automatically coalesces free space of a data block when it reaches 20% of available space.
• B. It minimizes row chaining during row insertion.
• C. It allows only 80% of space to be occupied in all data blocks of this table.
• D. It minimizes row migration during existing row data updation.

Examine the structure of the SALES table, which is stored in a locally managed tablespace with Automatic Segment Space Management (ASSM) enabled.

You want to perform online segment shrink to reclaim fragmented free space below the high water mark.
What should you ensure before the start of the operation?

• A. Row movement is enabled.
• B. Referential integrity constraints for the table are disabled.
• C. No pending transaction exists on the table.
• D. Extra disk space equivalent to the size of the segment is available in the tablespace.
• E. No queries are running on this table.

Which two tools can be used to configure static service information in the listener.ora file? (Choose two.)

• A. Oracle Net Manager
• B. Oracle Enterprise Manager Cloud Control
• C. Oracle Enterprise Manager Database Express
• D. Oracle Net Configuration Assistant
• E. Listener Control Utility (LSNRCTL)

You have altered a non-unique index to be invisible to determine if queries execute within an acceptable response time without using this index.
Which two are possible if table updates are performed which affect the invisible index columns? (Choose two.)

• A. The index is updated by the DML on the table.
• B. The index is not updated by the DML statements on the indexed table.
• C. The index automatically becomes visible in order to have it updated by DML on the table.
• D. The index becomes unusable but the table is updated by the DML.
• E. The index remains invisible.

Your database is open and the listener LISTENER is up. You issue the command:
LSNRCTL> RELOAD
What is the effect of RELOAD on sessions that were originally established by LISTENER?

• A. The sessions are not affected and continue to function normally.
• B. Existing connections are not disconnected; however, they cannot perform any operations until the listener completes the re-registration of the database instance and service handlers.
• C. Only sessions based on static listener registrations are disconnected.
• D. All the sessions are terminated and active transactions are rolled back.
