• C、cluster.es.server.websm
• D、cluster.sysmgt.websm.rte

第7题：

An administrator runs clstat on a cluster node and receives the following response： ’Can not get  Cluster Information.’ Which of the following daemons may need to be started in order to correct this problem？（）

• A、 topsvcs
• B、 clinfoES
• C、 snmpinfo
• D、 clsmuxpdES

第8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9题：

A new administrator is performing fallover testing on a two-node cluster and is concerned that the cascading resource group belonging to Node ’A’ did not reintegrate properly after the cluster was restarted on Node ’A’. A stable cluster is reported by clstat，and clRGinfo reports the resource group online on Node ’B’.  What type of configuration would cause this type of behavior？（）
