第2题：

A customer has a resource group rg1 configured on a two node cluster with the following policies：The customer has observed the following scenarios as nodes join the cluster during cluster start up. Scenario 1 Node1 joins cluster as first node - rg1 is acquired by Node1 Node2 joins cluster as second node - rg1 ismoved from Node1 to Node2 Scenario 2 Node2 joins cluster as first node - rg1 is acquired by Node2 Node1 joins cluster as second node - rg1 remainson Node2 Which of the following is the reason for this behavior？（）

第4题：

A cluster node has a failed fibre adapter requiring the node to be halted to replace it. To minimize downtime， what is the appropriate method of performing this repair？（）

• A、 Perform the cIRGmove command to move the node’s resources to another cluster node.
• B、 Perform a graceful stop of the cluster，replace the adapter，and restart the cluster.
• C、 Perform a force stop of the cluster node，replace the adapter，and restart the cluster. 
• D、 Perform a graceful takeover of the cluster，replace the adapter，and restart the cluster.

第5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.

第6题：

A cluster script failed because it was unable to set the hostname， and the Cluster Manager reported the event failure. What must be done prior to sue the "HACMP Problem Determination Tools" -> "Recover From Script Failure" to have the Cluster Manager resume cluster processing？（）  

• A、 Nothing， the "Recover From Script Failure" will correct the issue.
• B、 Disable and re-enable the effected Ethernet adapter by using ifconfig.
• C、 Correct the error by setting the hostname on the effected node from the command line.
• D、 Verify that the clinfo daemon is running prior to executing the "recover from scriptfailure".

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; }
