A two-node cluster is configured for mutual takeover with two service IP labels. The cluster is Being tested for fallover behavior. Both nodes in the cluster have two network interfaces （ent0’ and ’ent1’） configured with IPAT via IP Replacement. When the network cable is removed from the interface card with the service address （’ent0’）， the service address is moved to ’ent1’， and ’ent0’ is reconfigured on its boot address. When the network cable is replaced on ’ent0，the service address does not switch back to ’ent0’. What statement most accurately describes this situation？（） A、 EtherChannel is needed to automatically switch the service IP address back to ’ent0’.B、 This is the default behavior for a network interface failure with this configuration.C、 Gratuitous ARP support needs to be enabled for the IP Network Interface Module in SMIT.D、 The Inactive Network Takeover option should be set to "true" to forece the service addressback to ’ent0’.
A two-node cluster has both a single TCP/IP heartbeat and a single non-IP serial heartbeat. TheService Level Agreement regarding the speed of cluster fallover has been updated，and Fast Disk Takeover will be implemented to meet the new Service Level Agreement. Which of the following should be implemented to increase the reliability of Fast Disk Takeover？（） A、 Disk should be mirrored across separate storage enclosures.B、 Disk heartbeats should be added over multiple disk adapters.C、 Disk major and minor numbers should be set as unique across nodes.D、 Disk adapter queue_depth should be increased from the default values.
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
Following a successful cluster fallover， clstat returns no status， the snmpinfo command hangs. All Cluster resources appear to be active. What should be done to resolve this problem？（） A、 Restart all cluster nodes.B、 Verify that cluster.es.client.rte is installed on all nodes.C、 Use chssys -a -d -p -s clcomdES to enable cluster communication.D、 Use the /usr/sbin/snmpv3_ssw-1 command to revert SNMP from version 3 to version 1.
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.

Company.com has a two-node HACMP cluster with a single cascading resource group. Node ’A’ is the normal production node， and Node ’B’ is the standby node. One of the first steps in the HACMP test plan is to start the cluster and to verify that al elements for the resource group have been acquired. The administrator who is conducting the HACMP test starts the HACMP daemons on Node ’B’ with the ’smitty clstart" command. The administrator notices that Node ’B’ acquires the elements of the resource group， including a service IP labels，a shared volume group， and an application server that has been started. The expectation was that Node ’B’ would enter the cluster in a standby status， rather than acquiring production resources. What should the administrator do to correct this problem？（） A、 Change the cluster to a rotating design.B、 Change the Cascading without Fallback flag to true.C、 Change the Inactive Takeover field to false in the cluster configuration.D、 Nothing should be done. This is the default behavior for cascading resource groups，and node ’A’ should have been started first.
