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.

A step in the HACMP test plan is to gracefully stop the cluster on a node and to verify that the Shared resources fallover to the standby node. To prepare for this testing step， both nodes in the two-node cluster are in a stable state with the single resource group active on Node ’A’. Which of the following is the best way to execute this portion of the test plan？（） A、 Execute "lssrc -g cluster stop" on Node ’A’B、 Execute "cat /etc//motd /dev/kmem" on Node ’A’C、 Execute "/usr/es/sbin/cluster/utilities/sclstop -gr" on Node ’A’D、 Find the pid of cluster manager daemon on Node ’A’ and issue a "kill-9" against the pid

Which of the following would best verify the application functionality？（） A、 Perform a ping client verification test.B、 Review the number of active application processes.C、 Perform successful reads and writes to the application.D、 Run netstat -an to verify client connections to the listening ports.
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.
Following an unsuccessful cluster fallover test， it is determined that the nfsrg1 resource group was the problem causing the cluster to run the config_too_long evetn. The nfsrg1 resource group contains 10 nfs filesystems that are cross-mounted to the other cluster node. Without modify8ing the time until warning parameters，what can be done to enhance NFS fallover performance？（） A、 Increase the number of NFS daemons for increased performance.B、 Modify the nfsrg1 resource group to use local NFS cross-mounts.C、 Create a second resource group to manage half the NFS cross-mounts.D、 Create post events to handle the cross-mounts after fallover processing.
