第6题：

Company.com with a newly installed cluster has been checking the logfiles to determine if the  cluster has had any recent activity. The non-IP RS232 heartbeat connection seems to be having a difficulty. The serial network goes down，and then a couple of minutes later comes back up again. This pattern is repeated many times in the log.  If this system was installed without regard to best practices， what is the most likely problem with the serial network？（）  

• A、 The serial port is malfunctioning and needs to be repaired.
• B、 The baud rate is incorrectly specified in the AIX devices configuration.
