Which three statements are true concerning unplugging a pluggable database (PDB)?

The correct answer is B. The PDB must be dosed. D. The unplugged PDB can be plugged into the same multitenant container database (CDB) E. The unplugged PDB can be plugged into another CDB. B, not A:The PDB must be closed before unplugging it. D: An unplugged PDB containsdata dictionary tables, and some of the columns in these encode information in anendianness-sensitive way. There is no supported way to handle the conversion of suchcolumns automatically. This…

Explanation

B, not A:The PDB must be closed before unplugging it. D: An unplugged PDB containsdata dictionary tables, and some of the columns in these encode information in anendianness-sensitive way. There is no supported way to handle the conversion of suchcolumns automatically. This means, quite simply, that an unplugged PDB cannot be movedacross an endianness difference. E (not F):To exploit the new unplug/plug paradigm for patching the Oracle version most effectively,the source anddestination CDBs should share a filesystem so that the PDB's datafiles canremain in place.
