  • 第9题：

    A cluster node has three network interfaces that support three resource groups with three service  IP labels. Each IP label uses IPAT via IP aliasing. One of the adapters fails， and all of the IP labels on it are moved to other interfaces as expected. The system supports the "hot swap" replacement of the network interfaces， and the system engineer has corrected the problem.  What will happen to the service IP lab3els when the repaired adapter is noticed by HACMP？（）
