第4题：

Following a successful migration，it is highly recommended that concurrent Volume Groups be Converted to enhanced concurrent capable Volume Groups.  In order to follow this recommendation，what step must be completed first？（）  

• A、 The Volume Groups must be changed with chvg -E vgname.
• B、 The Volume Groups must be a member of a resource group and must be varied on al nodes of       the cluster.
• C、 The Volume Groups must be a member of a resource group and must be varied off all nodes      of the cluster.
• D、 The Volume Grups cannot be changed to enhanced concurrent capable because they must be      recreated with mkvg -C vgname.

第17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.
