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 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 three-node Network Load Balancing cluster. Each cluster node runs Windows Server 2003 and has a single network adapter. The cluster has converged successfully. You notice that the nodes in the cluster run at almost full capacity most of the time. You want to add a fourth node to the cluster. You enable and configure Network Load Balancing on the fourth node. However， the cluster does not converge to a four-node cluster. In the System log on the existing three nodes， you find the exact same TCP/IP error event. The event has the following description： "The system detected an address conflict for IP address 10.50.8.70 with the system having network hardware address 02：BF://0A：32：08：46." In the System log on the new fourth node， you find a similar TCP/error event with the following description： "The system detected an address conflict for IP address 10.50.8.70 with the system having network hardware address 03：BF://0A：32：08：46." Only the hardware address is different in the two descriptions. You verify that IP address 10.50.8.70 is configured as the cluster IP address on all four nodes. You want to configure a four-node Network Load Balancing cluster. What should you do？ （）A、 Configure the fourth node to use multicast mode.B、 Remove 10.50.8.70 from the Network Connections Properties of the fourth node.C、 On the fourth node， run the nlb.exe resume command.D、 On the fourth node， run the wlbs.exe reload command.
You have a server that runs Windows Server 2008 Enterprise Edition. The server has the FailoverClustering feature installed. The server has three nodes named NODE1， NODE2， and NODE3. The Microsoft Distributed Transaction Coordinator （MSDTC） resource is installed on the cluster. The cluster hasa dedicated cluster group named Group1 that includes the MSDTC resource. You discover that Group1 isunable to failover to NODE3 from NODE1 or NODE2. The failover from NODE1 to NODE2 functionswithout errors. You need to configure Group1 to support the failover between all cluster nodes. What should you do？（）A、Remove the MSDTC resource from Group1B、Select NODE3 as a preferred owner for Group1C、Remove NODE3 as a possible owner from all cluster resources in Group1D、Onfigure NODE3 as a possible owner for all cluster resources in Group1
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.
