Which of the following statements about stacked MAD detection is wrong?
- A . MAD proxy detection requires that all stack members are connected to the proxy device and the connected links are added to an Eth Trunk.
- B . MAD direct connection detection can be done through an intermediate device or you can choose to use ful1-mesh.
- C . When stacking systems act as agents for each other for MAD detection, the two stacking systems can use the same Domain ID.

- B . DHCP supports allocating fixed IP addresses to designated terminals. This allocation mechanism is called DHCP static allocation.
- C . If you only need to deliver gateway and DNS server information to the DHCP client, the DHCP Offer message sent by the DHCP server to the client will not carry the 0ptions field.
- D . When the DHCP client and DHCP server are in different Layer 3 networks, you need to configure a DHCP relay to forward messages between the client and the server.

Under the distributed gateway, VNI is divided into L2VNI and L3VNI. L2VNI is an ordinary VNI, which is mapped to the broadcast domain BD in a 1:1 manner to realize the forwarding of VXLAN packets within the same subnet: L3VNI is associated with a VPN instance and is used for forwarding VXLAN packets across subnets. () single choice
- A . True
- B . False
