According to the dual-system hot-standby networking diagram, which of the following statements is wrong about the dual-system hot-standby preemption function?
- A . The VRRP backup group itself has the preemption function. As shown in the figure, when USG_A fails and recovers, USG_A will use the preemption function to become the master state again.
- B . The preemption function of the VGMP management group is similar to that of the VRRP backup group. When the faulty backup group in the management group is restored, the priority of the management group will also be restored.
- C . By default, the preemption function is disabled
- D . After the VRRP backup group is added to the VGMP management group, the original preemption function on the backup group will become invalid, whether the preemption behavior occurs or not must be determined by the VGMP management group.
