第7题：

An administrator has a 2 node cluster running PowerHA version 5.5. They remove a resource group from theactive cluster configuration. When performing a verify and synchronize of the cluster， the administrator getsthe following error： "migcheck[471]： cl_connect（） error， nodename=Node1， rc=-1 cldare： A communication error prevents obtaining the VRMF from remote nodes. A DARE event cannot be run until this is corrected. Please ensureclcomd is running." What is the most likely cause of this error？（）

• A、There is a DARE lock in place
• B、A PowerHA migration is in progress
• C、Cluster services is not active on the other node

第10题：

Two MAG4610s are running in an active/passive cluster configuration. The system administrator is planning to apply a service package to the cluster.Which process should the administrator follow?（）

• A、Perform the upgrade on the active node of the cluster. When completed, the node reboots and then pushes the service package to the passive node automatically.
• B、Perform the upgrade on the passive node of the cluster. When completed, the node reboots and then pushes the service package to the active node automatically.
• C、On the clustering status page, disable the active node. Perform the upgrade on the disabled node. When completed and the node reboots, enable the node on the clustering status page.Repeat the process on the passive node.
• D、On the clustering status page, disable the passive node. Perform the upgrade on the disabled node. When completed and the node reboots, enable the node on the clustering status page.Repeat the process on the active node.
