A、The data is decrypted during SORT and JOIN operations. B、The data remains encrypted when it is read into memory. C、The data remains encrypted when it is stored in the redo logs. D、The data remains encrypted in the UNDO tablespace provided that the UNDO tablespace was created with the encryption option enabled.
A、Use Data Pump to transfer the existing data to a new encrypted tablespace B、Use ALTER TABLE MOVE to transfer the existing data to a new encrypted tablespace C、Use CREATE TABLE AS SELECT to transfer the existing data to a new encrypted tablespace D、Enable row movement for each table to be encrypted and then use ALTER TABLESPACE to encrypt the tablespace E、Encrypt the USER_DATA tablespace using the ALTER TABLESPACE statement so that all the data in the tablespace is automatically encrypted
