While executing a Cluster Test Plan， the administrators realize that they will need to email the  Operations and network on-call staff in the event of a network outage. 
What can be done to alert the on-call staff of network failures？（）   

The IP subsystem fallover behavior of a two-node cluster is being testing in a large client  organization. One of the tests is to simulate a network_down event and verify that HACMP movesthe single resource group to the standby node. 
What is the best way to simulate a network down condition？（）   

Company.com has a cluster with nodes that support "hot swap" adapters. During an upgrade of  The network infrastructure，an additional network adapter has been added to the nodes and configured in AIX. 
What is the next step required to add this adapter to HACMP？（）  

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’？（）

Company.com with a newly installed cluster has been checking the logfiles to determine if the  cluster has had any recent activity. The non-IP RS232 heartbeat connection seems to be having a difficulty. The serial network goes down，and then a couple of minutes later comes back up again. This pattern is repeated many times in the log. 
If this system was installed without regard to best practices， what is the most likely problem with the serial network？（）
