Which TWO statements are true about database parameters for databases in a Data Guard environment?

If DB_RECOVERY_FILE_DEST is specified, then LOG_ARCHIVE_DEST_n is not required for local archive logs.

The databases that are part of a Data Guard configuration must have different DB_UNIQUE_NAME initialization parameters.

COMPATIBLE must have identical values for primary and standby databases.

LOG_FILE_NAME_CONVERT applies to online redo logs and archived logs.

DB_FILE_NAME_CONVERT is only required if the standby database is on the same host as the primary database.
