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?() A、 Firewalls are not supported in a HACMP environment.B、 HACMP uses only TCP/IP so firewalls are not relevant.C、 Specific ports must be open for HACMP communications.D、 Dynamic routing must be used to properly route packets in a firewall-protected environment.
考题
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?() A、 The cluster must not be running.B、 The cluster.es.server.utils lpp must be installed.C、 The error notification module must be enabled in RSCT.D、 The permissions on /tmp/hacmp.out need to be changed to 774.

While installing the equipment for a new two-node cluster, it is discovered that the disk subsystem Rack has one connection to the power mains. The explanation given was that the disks are to be mirrored between the two disk drawers in the rack and that a failure in either of the disk drawers would simply result in half of the disk being lost. What can be done to avoid a single point of failure?() A、 Customize HACMP to overcome quorum issues.B、 Add a second PDU to separate the power connections.C、 Use RAID5 when implementing two IO racks in a HACMP environment.D、 Add another shared disk to each volume group to avoid quorum issues during fallover.

The IP subsystem fallover behavior of a two-node cluster is being testing in a large client organization. One of the tests is to simulate a network_down event and verify that HACMP movesthe single resource group to the standby node. What is the best way to simulate a network down condition?() A、 Turn off the IP core switch connecting the two nodes.B、 Issue the command "stopsrc -g inetd" on the node that has the resource group.C、 Issue the command "sh /etc/rc.tcpclean" on the node that has the resource group.D、 Simultaneously unplug all network cables from the node that has the resource group.
考题
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.
考题
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
考题
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.
