Does Import with impdp.exe just ADD or REPLACE a table content?

Question

Assume I have I dumpfile which I want to import with the impdp.exe tool.
Part of the dumpfile is the content of e.g. TABLE testtable123
Furthermore lets say that after the previous export of the dumpfile
some more data is added to the table while other data rows were meanwhile deleted.
So if I execute now the impdp.exe operation is the dumpfile data just ADDED
to the existing data in the current table testtable123 or does it completely REPLACE
all data rows in table testtable123?

So if I execute now the impdp.exe operation is the dumpfile data just ADDED
to the existing data in the current table testtable123 or does it completely REPLACE
all data rows in table testtable123[http://download.oracle.com/docs/cd/B14117_01/server.101/b10825/dp_import.htm#i1006538]
Note that if CONTENT=DATA_ONLY is specified, the default is APPEND, not SKIP
TABLE_EXISTS_ACTION={SKIP | APPEND | TRUNCATE | REPLACE}
APPEND loads rows from the source and leaves existing rows unchanged
REPLACE drops the existing table and then creates and loads it from the source. This is not a valid option if the CONTENT parameter is set to DATA_ONLY.
