单项选择题

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？（）

A. Turn off the IP core switch connecting the two nodes.
B. Issue the command "stopsrc -g inetd" on the node that has the resource group.
C. Issue the command "sh /etc/rc.tcpclean" on the node that has the resource group.
D. Simultaneously unplug all network cables from the node that has the resource group.

单项选择题A cluster administrator is performing fallover testing during a scheduled system outage. Node ’A’ Was forced down and eventually rebooted.

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.
