第1题:

A cluster administrator is performing fallover testing during a scheduled system outage. Node ’A’  Was forced down and eventually rebooted. When Node ’A’ reintegrates into the cluster, the resource group state is offline. No errors are found in reviewing the hacmp.out file.  What could have been done to ensure the resource group was acquired when cluster processing was restarted on Node ’A’?()

  • A、 Nothing,HACMP does not require them automatically.
  • B、 Force the remaining nodes down,then reintegrate them all.
  • C、 Select reacquire resources after forced down on start menu.
  • D、 Create a setting timer to bring the resource group online.

正确答案:C

第2题:

During the process of fallover testing, a client/server database needs to be tested. On the AIX Server, start/stop/cleanup scripts and server application functionality have been tested.  Before moving onto the next step of fallover testing,what action must be completed?()

  • B、 Verify that the client side application is functioning properly.
  • C、 Check hacmp.out log file to validate that the application server started.

第3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.

第5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?()
