IBM(000-237)章節(jié)練習(2019.05.10)

A node in a three-node cluster was started， ad it acquired the following three cascading resourcegroups： 
’rg1’， ’rg12’， and ’rg3’. The cluster design is to have ’rg1’ normally Node ’A’， ’rg2’ normally on Node ’B’， and rg3’ normally on Node ’C’. 
How can the administrator reposition the resource groups and correct the problem？（）  

A two-node cluster is configured for mutual takeover with two service IP labels. The cluster is Being tested for fallover behavior. Both nodes in the cluster have two network interfaces （ent0’ and ’ent1’） configured with IPAT via IP Replacement. When the network cable is removed from the interface card with the service address （’ent0’）， the service address is moved to ’ent1’， and ’ent0’ is reconfigured on its boot address. When the network cable is replaced on ’ent0，the service address does not switch back to ’ent0’. 
What statement most accurately describes this situation？（）   

Company.com wishes to use IPAT via IP replacement in a two-node mutual cluster. Each node  has two Ethernet 10/100/1000 adapters. Throughout the planning session，the customer has asked questions about subnet and VLAN requirements for the intended network topology. 
Which of the following best describes the network requirements？（）  

Node ’C’ has just completed reintegration in a three-node cluster. The hacmp.out logifle displays  The event node_up_complete for Node ’C’. The cluster administrator wishes to verify that the cluster is stable. 
In addition to reviewing the cluster log files，what utility should be run to verify the cluster state？（）  

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 recommended PTF is released to resolve reliability issues with bos .net.tcp.server. A Maintenance windows has been scheduled to install the PTF on all nodes. 
In order to complete the maintenance，what are the next logical steps to be completed after the install of the PTF on all nodes？（）

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？（）  

Company.com has an application that has a hard-coded hostname in the startup routines. The application is being made highly available using HACMP. During testing， the application does not start on the standby node because the hostname was not what the application expected. 
What can be done to fix this problem？（）

During the initial cluster design，a disk heartbeat，Point-to-Point non-IP network is being planned  as part of a three-node cluster implementation. The disk environment will use LVM mirroring for disk redundancy. The volume groups will be created as Enhanced Concurrent Capable. 
To facilitate disk heartbeating，how many disks per node and how many networks will be required？（）
