第1题:

A customer synchronizes the cluster in a virtualized environment. During the process the following warning isdisplayed: "For nodes with a single Network Interface Card per logical network configured, it is recommended to includethe file ’/usr/es/sbin/cluster/netmon.cf’ with a pingable IP address as described in the PowerHA PlanningGuide".
