Which four database parameters might be affected by or influence the creation of standby databases?

A. DB_NAME
B. ARCHIVE_LAG_TARGET
C. COMPATIBLE
D. DB_FILE_NAME_CONVERT
E. DB_UNIQUE_NAME
F. FAL_SERVER
G. STANDBY_ARCHIVE_DEST

ADEF

A: DB_NAME - On a primary database, specify the name used when the database was created. On a physical standby database, use the DB_NAME of the primary database. C: Ensure the COMPATIBLE initialization parameter is set to the same value on both the primary and standby databases. If the values differ, redo transport services may be unable to transmit redo data from the primary database to the standby databases. D: DB_FILE_NAME_CONVERT - Specify the path name and filename location of the primary database data files followed by the standby location. This parameter converts the path names of the primary database data files to the standby data file path names. E: DB_UNIQUE_NAME - Specify a unique name for each database. This name stays with the database and does not change, even if the primary and standby databases reverse roles. F: FAL_SERVER - Specify the Oracle Net service name of the FAL server (typically this is the database running in the primary role).
