单选题 An administrator has written a script to check that the contents of an application configuration file are identicalon all cluster nodes. The script has also been associated with a user defined custom verification method. Theadministrator would like the contents of this file to be checked and verified automatically on a daily basis.How can this be achieved?()

A

By using a job scheduler such as cron

B

By enabling automatic cluster verification

C

By including the script name in the file /usr/es/sbin/cluster/etc/clverify.rc

D

By including the custom method name in the file /usr/es/sbin/cluster/etc/rc.authomethods

单选题 A customer is in the process of testing their configuration prior to going live. The administrator discovers thatPowerHA is taking 31 seconds to deal with a standard NIC failure. What can the administrator do to speed upthe process of NIC failure detection and diagnosis?()

A

Tune the topsvcs NIM settings

B

Tune the grpsvcs NIM settings

C

Activate the fast failure detection (FFD) feature

D

Activate the Gigabit fast failover feature on the physical adapters

单选题 In a cluster using /etc/hosts for name resolution, which of the following describes the minimum requirementsfor the /etc/hosts file?()

A

IP address and IP label of each service and boot interface in the cluster

B

IP address and IP label of each service and boot interface in the cluster, loopback interface, and the hostname of the node

C

IP address and IP label of each service and boot interface in the cluster, the loopbackinterface, and the cluster gateway

D

IP address and IP label of each service and boot interface in the cluster, the loopbackinterface, the cluster gateway, and the subnet network addresses

B

An Apache compliant Web server

C

Web Based System Manager (WebSM)

D

Websphere Application Server Community Edition

单选题 An administrator has a two node cluster, Node1 and Node2, running resource group rg1. The resource groupis active on Node1. The administrator stopped cluster services and unmanaged the resource group on Node1to work on a problem. Now the administrator needs to move rg1 to Node2. Which of the following will achievethis?()

A

Perform a clstart on Node1 with ’Manage Resource Groups’ set to ’Manually’ and select the destination ofNode2

B

Perform a resource group move operation from Node1 to Node2 and select the option to ’Re-manageResource Groups’ set to ’Automatically’

C

Perform a clstop on Node1 with option to move resource groups, this will release the resource group fromNode1 and accquire the resource group on Node2.

D

Perform a clstart on Node1 with ’Manage Resource Groups’ set to ’Automatically’, then perform a resourcegroup move operation to move rg1 from Node1 to Node2

单选题 An administrator is configuring a PowerHA cluster consisting of two nodes across two physical Power systems,570-1 and 570-2. Node1 is an LPAR on 570-1Node2 is an LPAR on 570-2. Dev1 is an LPAR on 570-2 (this LPAR is not part of the cluster). The cluster will manage a single resource group, RG1, with a single application server, APP1. The resourcegroup will have a home node of Node1. Node1 is configured with 4.0 CPU desired, 0.4 minimum, 4.0 maximum, and 4 virtual processorsNode2 isconfigured with 0.4 CPU desired, 0.4 minimum, 4.0 maximum, and 4 virtual processors Dev1 is configuredwith 4.0 CPU desired, 0.4 minimum, 4.0 maximum, and 4 virtual processors When the resource group RG1 is acquired by Node2 the administrator would like to dynamically move 3.6processor entitlement units from Dev1 to Node2. How could the administrator achieve this in the PowerHAcluster?()

A

Create a custom event script to perform the change to CPU entitlement

B

Modify the extended performance tuning parameters for the cluster to modify CPU entitlement uponresource group acquisition

C

Customize the resource group attributes of RG1 so that the CPU entitlement is modified for Node2 uponresource group acquisition

D

Customize the application server attributes of APP1 so that the CPU entitlement is modified for Node2upon resource group acquisition
