问题:单选题During a planning session, the customer indicates that they intend to build two independent two- Node clusters (cluster ’A’ and ’B’) that will be provided shared storage form an IBM TotalStorage FAStT900 server. The customer intends to present 2 LUNs to cluster ’A’, and 2 LUNs to cluster ’B’. All hosts will be dual attached via fibre. What additional hardware or software is necessary to make this a valid configuration?()ASAN switchesBFibre channel Hub(s)CIBM Storage Manager AgentsDIBM Subsystem Device Driver
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An administrator has added an additional network adapter to each cluster node. The adapters have been configured and tested, and the /etc/hosts file has been updated. However,the adapters do not appear in the pick list when the administrator tries to define the adapters to HACMP. What would be required to correct this problem?()ARerun autodiscovery.BSynchronize the cluster.CRestart cluster services.DDelete and recreate the adapters.
问题:单选题An administrator uses C-SPOC to change the user password for all nodes that belong to a Resource group. The administrator must perform this operation on a node that is:()Aincluded in the resource group.Bcurrently managing the resource group.Cnot part of an application resource group.Dincluded in a cluster_admin resource group.
问题:单选题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?()AMore disk should be added to the disk heartbeat network,allowing more paths for heartbeats.BAn RS232 network is required to supply a more robust non-IP network when disk heartbeating is implemented.CThe network tunable parameters should be changed to allow more missed heartbeats since the disks may be heavily used.DAn error notification method is required to determine the action to take in response to a failure of the disk heartbeat.
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During Company.com planning session, the network administrator discusses the requirements of having a persistent MAC address associated with the IP Service address. How can this be accomplished using HACMP?()AEnable routed to handle dynamic route creation.BUse IPAT via IP aliasing and define the required MAC address.CAdd the Service IP Label to the /etc/cluster/ping_client_list.DUse IPAT via IP replacement and define the required MAC address.
问题:单选题Company.com has decided to implement the "Fast Disk Takeover" and "Disk Heart Beat" features of HACMP. What IBM distribution media will be required for a default installation?()AAIX media onlyBHACMP media onlyCAIX and HACMP mediaDHACMP and Concurrent Resource Manager media
问题:单选题Company.com moved their application start routines from the inittab and place them under HACMP control. During testing,the applications did not always start as desired. What is the best practice for the application start routines.()AAssume the system was stopped by a failure.BEnsure the hostname parameters is set correctly.CAssume the system was stopped by a graceful shutdown.DMount all volumes and file systems before running the application.
问题:单选题An existing cluster has an application node and database node. Changes in the application require both nodes to have access to the other’s data all of the time. Which facility managed by HACMP can be implemented with the least amount of impact?()ANFSBAFSCDFSDGPFS
问题:单选题During a planning meeting, Company.com indicates that they intend to make a relational Database highly available. The application has a pre-requisite that a kernel extension be loaded from /etc/inittab. How would this be managed in an HACMP environment?()AIt can be started with a crontab entry.BIt can be created as an Application Server.CIt can be added to a resource group as a dependency.DIt cannot be done because HACMP provides no method to order application start/stop scripts.
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A two-node cluster is attached via SAN to shared disk. The customer has requested that one of the nodes be moved to another room 300 feet away. However, this distance exceeds the length specified by the RS232 specifications. What solution would resolve the RS232 specification issue with the fewest additional components?()ATarget mode fiber channel can be used with a SAN solution.BThe heartbeat could be established by using a disk heartbeat.CAn RS232 line driver can be used to extend the existing serial connection.DThe NIM for the serial connection can be altered to compensate for the additional delay caused by the increased distance.
问题:单选题While performing LVM maintenance, the volume group datavg1 was exported and re-imported. The volume group is varied online, and the filesystems have been mounted. However, the database will not start. What action would most likely resolve this problem?()APerform a shown command on the VG device files.BPerform a syncvg to validate VG integrity.CPerform a redfinevg to correct the VGDA state.DPerform a synchlvodm to correct the LV ownership.

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.
