考题
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 four-node Network Load Balancing cluster. All nodes run Windows Server 2003. The cluster has converged successfully. You use Network Load Balancing Manager on the default host to configure all nodes of the cluster. The nodes have a single network adapter and are connected to the same switching hub device. Administrators of non-cluster servers that are connected to the same switching hub device report that their servers receive traffic that is destined for the cluster nodes. Receiving this additional network traffic impairs the network performance of the non-cluster servers. You need to ensure that traffic destined for only the cluster nodes is not sent to all ports of the switching hub device. You do not want to move the cluster to another switching hub device. What should you do？ （）A、 On one node， run the nlb.exe reload command.B、 On each node， run the wlbs.exe drainstop command.C、 Use Network Load Balancing Manager to enable Internet Group Management Protocol （IGMP） support on the cluster.D、 Use Network Load Balancing Manager to add a second cluster IP address.

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.
