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：（）A
included in the resource group.B
currently managing the resource group.C
not part of an application resource group.D
included in a cluster_admin resource group.

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？（）A
Use nodes of equal size.B
Create multiple resource groups and use loadlever.C
Use dynamic node priority to manage resource groups.D
Use an ordered list to manage resource group fallover.
问题
单选题In order to successfully install HACMP， which non-default AIX lpp is a requirement？（）A
bos.mp64B
bos.dataC
bos.net.tcp.serverD
rsct.compact.clients.sp
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？（）A
Perform the cIRGmove command to move the node’s resources to another cluster node.B
Perform a graceful stop of the cluster，replace the adapter，and restart the cluster.C
Perform a force stop of the cluster node，replace the adapter，and restart the cluster. D
Perform a graceful takeover of the cluster，replace the adapter，and restart the cluster.
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？（）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.
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？（）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.

单选题Company.com performs cluster verification every Sunday night with a corn job. The systems administrator reviews the /var/hacmp/clverify/clverify.log on Monday morning and notice that cluster verification posted a message about inconsistent filesystem names in one of the shared volume groups. What should the administrator do？（）A
Cause a fallover to occur on the resource group.B
Export the volume groups and re-import them on all nodes.C
Run an importvg -L command on all the nodes in the cluster.D
Investiage recent changes to the shared volume group and use C-SPOC to correct inconsistencies.
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？（）A
Perform a shown command on the VG device files.B
Perform a syncvg to validate VG integrity.C
Perform a redfinevg to correct the VGDA state.D
Perform a synchlvodm to correct the LV ownership.
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？（）A
SAN switchesB
Fibre channel Hub（s）C
IBM Storage Manager AgentsD
IBM Subsystem Device Driver
问题
单选题Company.com is considering converting from IPAT via replacement to IPAT via IP aliasing. What condition of IPAT via IP aliasing must be taken into consideration？（）A
The clients must support gratuitous ARP.B
The network type must support gratuitous ARP.C
Additional TCP/IP interfaces must be allocated for backup in case of failure.D
Using IPAT via IP aliasing will reduce the number of rotating resource groups that can be used.
问题
单选题One service IP label and one volume group are assigned to a resource group in a cluster. An Additional service IP label and volume group need to be added to the resource group. How can this be done with the minimum disruption of the cluster？（）A
Make the changes in HACMP and synchronize the cluster.B
It cannot， because changes like this cannot be made while the cluster is running.C
Make the changes in HACMP and wait until the next failure for the changes to take affect.D
Use the forced option to stop the cluster，make the changes，and restart cluster services.
问题
单选题If a kill -9 is performed on the clstrmgrES process， the default action is to halt the system. Tochange the default action to do something other then halting the system， which of the following files must be modified？（）A
/usr/es/sbin/cluster/etc/clexit.rcB
/usr/es/sbin/cluster/etc/hacmp.termC
/usr/es/sbin/cluster/etc/rc.clusterD
/usr/es/sbin/cluster/etc/rc.shutdown
问题
单选题To enhance the availability of an application running under HACMP， a decision was made to use The application monitoring facility. The application consists of several components and can take several minutes to initialize. The components use socket communication and can be initialized in any order as long as it is a serial order. The customer’s concern is that if the application stop and start scripts are used during application monitoring recovery，it may take an extraordinary length of time to reset all of the application components. What can be done to ensure the best recover time？（）A
Use a process monitor that restarts the named processes in the original start order.B
Use the defined application start and stop scripts to control the application if there is a failure.C
Use multiple application monitors for this resource group to enable the monitoring of the specific components of the resource group.D
Use application cleanup and restart scripts designed to determine the state of the various components of the application and start only the parts required.
问题
单选题After an HACMP migration， which included a large number of shared disks，cluster testing is performed. During testing， it becomes apparent that Fast Disk Takeover is not working properly. Which of the following is the most likely cause of the problem？（）A
The shared volume groups have not been converted to Big VGs.B
The ’t factor needs to be set on the volume group using chvg -t 2 vgname.C
The shared volume groups have not been converted to enhanced concurrent mode.D
The shared volume groups need to be varied on using the passive varyon option on all nodes.
