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？（）
A. They will migrate back to the repaired interface.
B. They will not move，the interface will join the pool of available resources.
C. They will not move； the interface will join the cluster as an available non-service adapter.
D. They will migrate to the repaired interface to create an equal number of service IP labels per interface. -
