第3题：

An administrator has a two node cluster， Node1 and Node2， running resource group rg1. The resource groupis active on Node1. The administrator stopped cluster services and unmanaged the resource group on Node1to work on a problem. Now the administrator needs to move rg1 to Node2. Which of the following will achievethis？（）

• A、 Two cluster with two resource groups in a mutual takeover configuration.
• B、 One cluster with two cascading resource groups in a mutual takeover configuration.
• C、 One cluster with two rotating resource groups in a one-sided hot standby configuration.
• D、 Two clusters with two resource groups in a hot-standby configuration with a newly acquired third node.

第5题：

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.
