第1题：

第2题：

During a cluster functionality test， and administrator performs a graceful stop for Node ’B’ in a three-node cluster. What is the expected state of the cluster after Node ’B’successfully completes？（）  

• A、 All cluster resources halt on Node ’B’，and one or both surviving nodes will gracefully acquire the resources.
• B、 All cluster processes halt on Node ’B’，the cluster resources remain active，and the remaining  nodes take no action.
• C、 All cluster processes stay active on Node ’B’，cluster resources are halted，and the remaining nodes take no action.
• D、 All cluster resources will stop，cluster processes halt on Node ’B’，and the remaining cluster nodes take no action.

During a planning session， it is determined that a three node cluster （Node ’A’， Node ’B’， and Node ’C’） will meet the customer’s application needs. Node ’B’ will be a hot-standby fallover node for both Node ’A’ and Node ’C’ resource groups.  A serial network for this cluster will require which connections？（）  

• A、 A single serial network between Node ’A’ and Node ’B’ and Node ’C’
• B、 A point-to-point link between Node ’A’ and Node ’C’，and Node ’B’ and Node ’C’
• C、 A serial network between Node ’A’ and Node ’C’，and a serial network between Node ’B’ and Node ’C’
• D、 A point-to-point link between Node ’A’ and Node ’B’ Node ’B’ and Node ’C’ and Node ’A’ ad Node ’C’

第5题：

The resource group configuration for a four node cluster is shown below：Which resource groups will be acquired by node N2 if it joins the cluster first？（）

• A、rgC、rgE
• B、rgC、rgD
• C、rgE、rgB、rgD
• D、rgC、rgD、rgE

第6题：

If both nodes in a chassis cluster initialize at different times, which configuration example will allow you to ensure that the node with the higher priority will become primary for your RGs other than RG0?（）

• A、[edit chassis cluster] user@host# show redundancy-group 1 { node 0 priority 200; node 1 priority 150;preempt; }
• B、[edit chassis cluster] user@host# show redundancy-group 1 { node 0 priority 200; node 1 priority 150; monitoring; }
• C、[edit chassis cluster] user@host# show redundancy-group 1 { node 0 priority 200; node 1 priority 150; control-link-recovery; }
• D、[edit chassis cluster] user@host# show redundancy-group 1 { node 0 priority 200; node 1 priority 150; strict-priority; }

第7题：

A three-node cluster experienced a node failure. The resource groups were acquired as cexpected. The node has been repaired，and HACMP has been restarted.  How does the operator determine that the node has successfully re-integrated into the cluster？（）  

• A、 Use the clstat command.
• B、 Use the cIRGinfor command.
• C、 Tail the /etc/hacmp.out file and wait for "node_up_complete" to finish successfully.
• D、 Tail the /usr/es/adm/cluster.log file and wait for "node_up_complete" to finish successfully.

第9题：

A step in the HACMP test plan is to gracefully stop the cluster on a node and to verify that the Shared resources fallover to the standby node. To prepare for this testing step， both nodes in the two-node cluster are in a stable state with the single resource group active on Node ’A’.  Which of the following is the best way to execute this portion of the test plan？（）
