Which of the following is correct about packet encapsulation order of L2TP over IPSec?

• A.The sequence from the first encapsulation to the post encapsulation is IPSec>L2TP->UDP->PPP
• B.The sequence from the first encapsulation to the post encapsulation is PPP>L2TP->UDP->IPSec
• C.The sequence from the first encapsulation to the post encapsulation is IPSec>PPP->L2TP->UDP
• D.The sequence from the first encapsulation to the post encapsulation is PPP>UDP->L2TP->IPSec

According to the dual-system hot backup networking diagram, which of the following statements is incorrect regarding the dual-system hot backup preemption function?

• A.By default, preemption function is disabled
• B.The preemption function of the VGMP management group is similar to that of the VRRP backup group. When the fault of a backup group in the management group recovers, the priority of the management group is also restored.
• C.After the VRRP backup group is added to the VGMP management group, the original preemption function on the backup group will become invalid. The preemption behavior must be determined by the VGMP management group.
• D.The VRRP backup group has its own preemption function. As shown in the figure, after USG_A fails and recovers, USG_A uses the preemption function to revert to the master state.
