问题：单选题During the installation of a cluster， the non-IP network failed. The cause was a connector that was Not properly secured. The customer wants a better notification method in the event that the non-IP network fails in the future. How could customization of the cluster be accomplished？（）ACustomize the node up event script to send an email to the operator.BHave HACMP send mail when the non-IP network fails by customizing the RG_MMOVE event script.CChange the network module to be slower so that a temporary failure of the non-IP network would not report an error.DUse snmp or clinfo to monitor the status of the non-IP network and dispatch some type of warning message.

问题：单选题Company.com has a four-node cluster （nodes ’A’， ’B’， ’C’， and ’D’）. The nodes are set up in Resource group pairs. Node ’A’ falls over to Node ’B’， and Node ’C’ falls over to Node ’C’. During a maintenance windows， it was discovered that the six resource groups on Node ’A’ are too much to be adequately handled by Node ’B’. What could be done to better utilize the available resources during fallover？（）AImplement Work Load manager so that the application monitors for additional resource requirements.BAdd a fifth node to function as a load leveler in order to control the dispatching of the resource jobs.CImplement Dynamic Node Priorities in the resource groups in order to find a node with suitable system resources.DReduce the number of resource groups on Node ’A’ to 1 in order to ensure faster and more robust fallover to a single system.

问题：单选题An HACMP cluster has three nodes of unequal size. The largest node is Node ’A’. The primary application on Node ’A’ has two components. One component is memory intensive， the other is IO intensive. Nodes ’B’ and ’C’ are running web servers and databases that access information produced by applications on Node ’A’. The customer requires the most performance from the primary application and wants all nodes available for fallover processing. Which of the following is the best solution for meeting the customer requirements？（）AUse nodes of equal size.BCreate multiple resource groups and use loadlever.CUse dynamic node priority to manage resource groups.DUse an ordered list to manage resource group fallover.

问题：单选题Company.com has a new computer room that will be used to house a new HACMP cluster. Onceof the outstanding features of the new computer room was the new large air conditioner. This unit has enough excess capacity for more than double the planned amount of equipment. Another feature of this computer room was the dual electric supplies to the room housed in two separate power panels. How would this impact the overall availability of the environment？（）ADual power feeds will make the installation difficult to manage and less high available.BThe single air conditioner is a single point of failure and the customer should be made aware of the issue.CThe single air conditioner is a single point of failure and HACMP should be customized to compensate for the issue.DA single power feed should be used to avoid ground loops in the computer room causing premature failure of the systems.

问题：单选题In order to successfully install HACMP， which non-default AIX lpp is a requirement？（）Abos.mp64Bbos.dataCbos.net.tcp.serverDrsct.compact.clients.sp
问题：单选题Company.com has a large network control center with an SNMP based monitoring tool running on a non-IBM Unix like system. It has become desirable for the network control center to monitor the activity of an HACMP cluster. What feature in HACMP can assist with this？（）Ahacmp.myBhacmp.mibChacmp.defsDhacmp.snmp

问题：单选题A cluster node has a failed fibre adapter requiring the node to be halted to replace it. To minimize downtime， what is the appropriate method of performing this repair？（）APerform the cIRGmove command to move the node’s resources to another cluster node.BPerform a graceful stop of the cluster，replace the adapter，and restart the cluster.CPerform a force stop of the cluster node，replace the adapter，and restart the cluster. DPerform a graceful takeover of the cluster，replace the adapter，and restart the cluster.

问题：单选题While executing a Cluster Test Plan， the administrators realize that they will need to email the Operations and network on-call staff in the event of a network outage. What can be done to alert the on-call staff of network failures？（）ACustomize clstat to send a mail message.BCustomize an Event Notification method.CCustomize an Error Notification method.DCustomize clinfo to send an SNMP trap.
问题：单选题While performing a site survey to document the existing environment before implementing a new HACMP cluster， it was discovered that a port filtering firewall was being used to protect the production system. The plan is to continue using the firewall and add a second firewall to avoid a single point of failure. Each node in the two-node cluster will have all of its network adapters connected to the firewalls， and all connections to the nodes will pass through these firewalls. What must be considered about HACMP in a firewall environment？（）AFirewalls are not supported in a HACMP environment.BHACMP uses only TCP/IP so firewalls are not relevant.CSpecific ports must be open for HACMP communications.DDynamic routing must be used to properly route packets in a firewall-protected environment.
问题：单选题During implementation of a two-node cluster，it is determined that error notification for the shared Disk subsystem would be beneficial. Which of the following is a pre-requisite for implementing automatic error notification？（）AThe cluster must not be running.BThe cluster.es.server.utils lpp must be installed.CThe error notification module must be enabled in RSCT.DThe permissions on /tmp/hacmp.out need to be changed to 774.
问题：单选题An install of cluster .es software failed. Output from the failure indicates missing system requisites. Every subsequent attempt to install the software abended. In order for the cluster to install，the most likely way for the administrator to resolve this problem is to install the "bos.data" and which other fileset（s）？（）Arsct.*BxIC* and rsct.*Cbos.adt.* and rsct.*Dcsm.*.rte and rsct.*
