A new administrator is performing fallover testing on a two-node cluster and is concerned that the cascading resource group belonging to Node ’A’ did not reintegrate properly after the cluster was restarted on Node ’A’. A stable cluster is reported by clstat，and clRGinfo reports the resource group online on Node ’B’. 
What type of configuration would cause this type of behavior？（）  

单项选择题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.
C. The serial port is not a port approved to support HACMP heartbeat traffic.
D. The baud rate is incorrectly specified in the HACMP interface configuration.

单项选择题An administrator has had a request from the data center for method to monitor the status of an  HACMP cluster. The monitoring software environment currently used is not compatible with SNM at this time， and there is not time to crate a new tool. There is also a restriction that the data center personnel not be allowed to login to the HACMP cluster nodes. What method will provide the solution for customer？（）

A. The clstat.cgi program will provide a solution.
B. The customer must install Tivoli with the HACMP plugin for monitoring the cluster.
C. The clinfo program included in the HACMP distribution will solve the monitoring issues.
