A. BACKGROUND_DUMP_DEST

C. CORE_DUMP_DEST

D. USER_DUMP_DEST

E. DIAGNOSTIC_DEST

F. All of the above

Answer: ACD

答案解析：

 Beginning with Release 11g of Oracle Database, because all diagnostic data, including the alert log, are stored in the ADR, the initialization parameters BACKGROUND_DUMP_DEST and USER_DUMP_DEST are deprecated. They are replaced by the initialization parameter DIAGNOSTIC_DEST, which identifies the location of the ADR.
