单项选择题

During normal cluster processing in a five-node cluster，one of the nodes unexpectedly crashes. A review of the system dump indicates that a DMS timeout has occurred. The cluster is configured to use disk heartbeats as a Point-to-Point network.
What should be done to address the problem with this configuration？（）

A. More disk should be added to the disk heartbeat network，allowing more paths for heartbeats.
B. An RS232 network is required to supply a more robust non-IP network when disk heartbeating is implemented.
C. The network tunable parameters should be changed to allow more missed heartbeats since the disks may be heavily used.
D. An error notification method is required to determine the action to take in response to a failure of the disk heartbeat.

单项选择题A two-node cluster provides NFS exports to a variety of UNIX clients. During fallover testing，it is determined that some clients are unable to mount the exported filesystems after fallover，and before node reintegration. It is verified that the filesystems belong to a resource group and are correct in usr es sbin cluster etc exports. Which of the following may provide a possible solution to this problem？（）

A. Use HWAT for IPAT to provide more reliable NFS serving.
B. Use AIX Fast Connect to provide more robust NFS serving.
C. Use NFS Cross Mounting to allow both nodes to export NFS properly.
D. Use the "Filesystem Mounted before IP Configured" flag to provide more predictable NFS serving.

单项选择题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？（）

A. The resource group DNP has been configured.
B. The resource group option CWOF has been enabled.
C. The resource group option Inactive Takeover is set.
D. A resource group fallback timer has been configured.

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Duringaclusterfunctionalitytest，andadministratorperformsagracefulstopforNode’B’inathree-nodecluster.WhatistheexpectedstateoftheclusterafterNode’B’successfullycompletes？（）

A. All cluster resources halt on Node ’B’，and one or both surviving nodes will gracefully acquire the resources.
B. All cluster processes halt on Node ’B’，the cluster resources remain active，and the remaining nodes take no action.
C. All cluster processes stay active on Node ’B’，cluster resources are halted，and the remaining nodes take no action.
D. All cluster resources will stop，cluster processes halt on Node ’B’，and the remaining cluster nodes take no action.

单项选择题During the process of fallover testing， a client server database needs to be tested. On the AIX Server， start stop cleanup scripts and server application functionality have been tested. Before moving onto the next step of fallover testing，what action must be completed？（）

A. Run who -a and validate that client connections are restored.
B. Verify that the client side application is functioning properly.
C. Check hacmp.out log file to validate that the application server started.
D. Verify that the application will successfully stop and restart on the fallover node.
