Examine the following query output: 

You issue the following command to import tables into the hr schema: $ > impdp hr/hr directory = dumpdir dumpfile = hr_new.dmp schemas=hr TRANSFORM=DISABLE_ARCHIVE_LOGGING: Y Which statement is true? 

Answer options:

A. All database operations performed by the impdp command are logged.
B. Only CREATE INDEX and CREATE TABLE statements generated by the import are logged.
C. Only CREATE TABLE and ALTER TABLE statements generated by the import are logged.
D. None of the operations against the master table used by Oracle Data Pump to coordinate its activities are logged.

C

Note from Oracle Documentation: With redo logging disabled, the disk space required for redo logs during an Oracle Data Pump import will be smaller. However, to ensure recovery from media failure, the DBA should do an RMAN backup after the import completes. Even with this parameter specified, there is still redo logging for other operations of Oracle Data Pump. This includes all CREATE and ALTER statements, except CREATE INDEX, and all operations against the master table used by Oracle Data Pump during the import.
