The application tables owned by the user TEST in a test database need to be exported to the APPS schema in the production database by using Data Pump. Which option of Data Pump Import would you use to accomplish this?
You want to track and store all transactional changes to a table over its lifetime. To accomplish this task, you enabled Flashback Data Archive with the retention of 5 years. After some time, the business requirement changed and you were asked to change the retention from 5 years to 3 years. To accomplish this, you issued the following command:
ALTER FLASHBACK ARCHIVE fla1 MODIFY RETENTION 3 YEAR;
What is the implication of this command?
A. The command produces an error because the retention time cannot be reduced.
B. All historical data is retained but the subsequent flashback data archives are maintained for only
C. All historical data is purged and the new flashback data archives are maintained for three years.
D. All historical data older than three years is purged from the flashback archive FLA1.
Your company wants to “shred” (delete) historical data changes to the Taxes table after ten years. When you create the Flashback Data Archive for Taxes, you specify a retention time of ten years:
CREATE FLASHBACK ARCHIVE taxes_archive TABLESPACE tbs1 RETENTION 10 YEAR;
When history data from transactions on Taxes exceeds the age of ten years, it is purged. (The Taxes table itself, and history data from transactions less than ten years old, are not purged.)

B. The allocation unit size may vary but the extent size is fixed.
C. The allocation unit size and extent size are fixed for all the disks in a disk group and cannot be changed.
D. Extent management is completely automated.
Which are the prerequisites for performing flashback transactions on your database? (Choose all that apply.)
A. Undo retention guarantee for the database must be configured.
B. Supplemental log must be enabled for the primary key.
C. Supplemental log must be enabled.
D. Execute permission on the DBMS_FLASHBACK package must be granted to the user.
