You are the network administrator for TestKing. The network consists of a single Active Directory domain named testking.com. All domain controllers run Windows Server 2003. The sales department recently hired 10 new employees. User accounts for these employees were created in Active Directory. The manager of the sales department sent you a list of a new users and asked you to add the user accounts to an existing global group named SalesDept. You need to add the users to the SalesDept global group. What are two possible ways to achieve this goal? Each correct answer presents a complete solution. Choose two.（）A、Use the dsadd user command to add the user accounts to the SalesDept global group.B、Use the dsadd group command to add the user accounts to the SalesDept global group.C、In Active Directory Users and Computers, select all 10 user accounts. Right-click the selected users, and then select the Properties menu command.D、In Active Directory Users and Computers, select all 10 user accounts.

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 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 needs to add a new file system to an existing volume group that is being made Highly available by HACMP？ What is the best procedure that minimizes down time of the applications？（） A、 Use C-SPOC to add the file system while the cluster is running.B、 Add the file system，and them perform the exportvg and importvg on the required nodes.C、 Stop the cluster，add the new file system， and synchronize the cluster then restart HACMP.D、 Break the reservation locks on the disk drives while the cluster is active and add the file system.
