An enterprise has three nodes: -Node ’A’ is a production database, -Node ’B’ is a production Application server, and -Node ’C’ is a test and development node. Node ’C’ is used by six programmers to develop and the production application as business critical and would like to make it highly available with HACMP.

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’.

You are the network administrator for your company. The network consists of a single Active Directory domain. All computers on the network are members of the domain. You administer a Network Load Balancing cluster that consists of three nodes. Each node runs Windows Server 2003 and contains a single network adapter. The Network Load Balancing cluster can run only in unicast mode. The Network Load Balancing cluster has converged successfully. To increase the utilization of the cluster, you decide to move a particular application to each node of the cluster. For this application to run, you must add a Network Load Balancing port rule to the nodes of the cluster. You start Network Load Balancing Manager on the second node of the cluster. However, Network Load Balancing Manager displays a message that it cannot communicate with the other two nodes of the cluster. You want to add the port rule to the nodes of the cluster. What should you do? ()A、 Use Network Load Balancing Manager on the Network Load Balancing default host to add the port rule.B、 Change the host priority of the second node to be the highest in the cluster, and then use Network Load Balancing Manager to add the port rule.C、 Run the nlb.exe drain command on each node, and then use Network Load Balancing Manager to add the port rule.D、 Add the port rule through Network Connections Properties on each node.
You are a network administrator for your company. You install Windows Server 2003 on two servers named Server1 and Server2. You configure Server1 and Server2 as a two-node cluster. You configure a custom application on the cluster by using the Generic Application resource, and you put all resources in the Application group. You test the cluster and verify that it fails over properly and that you can move the Applications group from one node to the other and back again. The application and the cluster run successfully for several weeks. Users then report that they cannot access the application. You investigate and discover that Server1 and Server2 are running but the Application group is in a failed state. You restart the Cluster service and attempt to bring the Application group online on Server1. The Application group fails. You discover that Server1 fails, restarts automatically, and fails again soon after restarting. Server1 continues to fail and restart until the Application group reports that it is in a failed state and stops attempting to bring itself back online. You need to configure the Application group to remain on Server2 while you research the problem on Server1. What should you do? ()A、 On Server2, configure the failover threshold to 0.B、 On Server2, configure the failover period to 0.C、 Remove Server1 from the Possible owners list.D、 Remove Server1 from the Preferred owners list.
Company.com has a two-node HACMP cluster with a single cascading resource group. Node ’A’ is the normal production node, and Node ’B’ is the standby node. One of the first steps in the HACMP test plan is to start the cluster and to verify that al elements for the resource group have been acquired. The administrator who is conducting the HACMP test starts the HACMP daemons on Node ’B’ with the ’smitty clstart" command. The administrator notices that Node ’B’ acquires the elements of the resource group, including a service IP labels,a shared volume group, and an application server that has been started. The expectation was that Node ’B’ would enter the cluster in a standby status, rather than acquiring production resources. What should the administrator do to correct this problem?() A、 Change the cluster to a rotating design.B、 Change the Cascading without Fallback flag to true.C、 Change the Inactive Takeover field to false in the cluster configuration.D、 Nothing should be done. This is the default behavior for cascading resource groups,and node ’A’ should have been started first.
