问题:单选题An administrator mistakenly shutdown production after a fallover because the service IP address Was shifted from the normal production node to the standby node. What can be done to avoid this type of mistake in the future?()AInclude the service IP address in the administrator’s PS1 promptBAlias the service IP address to the hostname in the /etc/host fileCDefine a persistent IP address with HACMP and make it a practice to use the persistent address for administration workDAdd a DNS entry to map the standby node name to the service IP address so telnet connections will be to the correct node

问题:单选题Using the C-SPOC utilities, an administrator has created a new volume group and filesytems. Theadministrator performs an Isvg -I command on the volume group and notices that the log logical volume created in C-SPOC is closed/syncd and loglv01 has been created and is in use. What step was required in order for the logfile created by C-SPOC to be used.()APerform the C-SPOC logform utility option prior to creating any filesystems.BManually perform a logform outside of C-SPOC prior to creating any filesystems.CRun a logredo command and select log logical volume created in C-SPOC as the preferred jfslog.DUse C-SPOC to delete and recreate the log logical volume,set the perform logform option to true.

问题:单选题Company.com performs a cluster verification on a regular basis. Cluster verification is successfulbut the cluster sometimes fails to start the applications during a fallover. Investigation of the issue has revealed that the non-shared component of the application configuration information is not being kept up to date on the secondary nodes. What can be used to help resolve this issue?()AA pre-eventBError notificationCApplication monitoringDCustom verification methods
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Company.com has non-IBM fibre attached storage. The storage is connected to a node in the cluster that has multiple adapters and virtual paths. There is a concern about detecting the loss of one of the fibre adapters since there is no indication to the administrator that one has failed. What feature of HACMP can be sued to assist with this issue?()ADisk heartbeatBError notificationCEvent notificationDApplication monitor

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 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 Enhanced Journeyed File System that is in a shred non-concurrent Volume Group is growing at an unexpected rate. It is the administrator’s task to enlarge the filesystem without interrupting service. What method should be sued to achieve this goal?()AUse HACMP C-SPOC to increase the size of the JFS2 filesystem.BUse the smitty jfs2 fastpath to increase the size of the JFS2 filesystem.CUse HACMP C-SPOC to increase the size of the JFS2 filesystem and inline JFS2 logs.DUse mklvcopy hdisk# 2 jfs2lvname to increase the size of the JFS2 filesystem,then use splitlvcopy jfs2lvname 1 -y newjfs2lvname hdisk# to present the increased JFS2 filesystem to HACMP.

Which of the following configuration alternatives will provide the fastest fallover?()AIPAT via IP Aliasing,default shared volume groupsBIPAT via IP Replacement default shared volume groupsCIPAT via IP Aliasing,enhanced concurrent volume groupsDIPAT via IP Replacement,enhanced concurrent volume groups
问题:单选题When the clverify utility is run,verification checks use ODM data provided by the common communication infrastructure. This provides efficient access to configuration ODMs from the other nodes. The utility manages these files by storing the copies in various directories depending on the success or failure of the verification pass. By default,this directory is "/var/hacmp/clverify/current/nodename/ if the ’current’ directory still exists when clverify stops running,this indicates which of the following?()AA successful completion of clverifyBA problem with the clverify utilityCAll nodes agree on active configurationDConfiguration differences between current and last successful clverify

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.
