What feature in HACMP can help resolve this issue?()ADisk based heartbeatsBHeart beating via IP aliasingCIP aliases for the non-service addressesDA single subnet for all non-standby adapters
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Company.com with an EtherChannel implementation is considering an HACMP solution. What considerations must be addressed in planning this configuration?()AHardware address takeover must be configured.BIPAT via IP aliasing is required for EtherChannel.CEtherChannel must be defined as a separate network.DHACMP does not support the fallover of EtherChannel.
问题:单选题While reviewing cluster logs, and administrator notice that an event, network_down rs232a, occurred on the previous day. After verifying the physical network connections and device states, what command can be used to verify the cluster state?()AclstatBcllsifCclsnapshotinfoDclcheck_server
问题:单选题An administrator has just imported a shred Volume Group that had been created on another system in the cluster. In order for the shred volume to be used in the cluster, what is the most important step for the administrator to take first?()AChange the quorum required to false.BChange the Volume Group auto vary on to yes, and then vary off the Volume Group.CChange the auto vary on value of the Volume Group to no, and then vary off the volume group.DSet the Volume Group major number to the same value that the Volume Group had on the system on which it was created.
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 the process of fallover testing, a client/server database needs to be tested. On the AIX Server, start/stop/cleanup scripts and server application functionality have been tested. Before moving onto the next step of fallover testing,what action must be completed?()ARun who -a and validate that client connections are restored.BVerify that the client side application is functioning properly.CCheck hacmp.out log file to validate that the application server started.DVerify that the application will successfully stop and restart on the fallover node.

问题:单选题Company.com with a newly installed cluster has been checking the logfiles to determine if the cluster has had any recent activity. The non-IP RS232 heartbeat connection seems to be having a difficulty. The serial network goes down,and then a couple of minutes later comes back up again. This pattern is repeated many times in the log.

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.
