As shown in the figure, the management VLAN of the LAN is VLAN 10, the AP obtains an IP address through DHCP, and the network segment is 10.1.1.0/24 AP. AC and AR are DHCP client, DHCP relay device and DHCP server respectively. Which of the following is the correct configuration about the configuration of the DHCP relay device and the DHCP server? (Multiple choice)

Question

Accepted Answer

A. [AC] dhcp server group AP
[AC-dhcp-server-group-AP] dhcp server 172.21.1.2
[AC-dhcp-server-group-AP] quit
[AC] interface Vlanif10
[AC-Vlanif10] dhcp select relay
[AC-Vlanif10] dhcp relay server-select AP
[AC-Vlanif10] quit D. [AR] interface GigaEthernet0/0/1
[AR-GigabitEthernet0/0/1] dhcp select global
[AR-GigabitEthernet0/0/1] quit
[AR] interface GigaEthernet0/0/1
[AR-GigabitEthernet0/0/1] ip address 172.21.1.2 24
[AR] ip-pool-AP network 10.1.1.0 mask 24
[AR] ip-pool-AP gateway-list 10.1.1.1
[AR] ip-pool-AP excluded-ip-address 10.1.1.1
[AR] ip-pool-AP quit
[AR] interface GigaEthernet0/0/1
[AR-GigabitEthernet0/0/1] dhcp select global
[AR-GigabitEthernet0/0/1] quit
[AR] ip route-static 10.1.1.0 255.255.255.0 172.21.1.1

Answer

B. [AR] interface GigaEthernet0/0/1
[AR-GigabitEthernet0/0/1] ip address 172.21.1.1 24
[AR-GigabitEthernet0/0/1] dhcp select global
[AR-GigabitEthernet0/0/1] quit
[AR] ip-pool-AP network 172.21.1.0 mask 24
[AR] ip-pool-AP gateway-list 172.21.1.1
[AR] ip-pool-AP excluded-ip-address 172.21.1.1
[AR] ip-pool-AP quit

Answer

C. [AC] interface GigaEthernet0/0/1
[AC-GigabitEthernet0/0/1] ip address 10.1.1.1 24
[AC-GigabitEthernet0/0/1] dhcp select global
[AC-GigabitEthernet0/0/1] quit
[AC] ip route-static 10.1.1.0 255.255.255.0 172.21.1.1

As shown in the figure, the management VLAN of the LAN is VLAN 10, the AP obtains an IP address through DHCP, and the network segment is 10.1.1.0/24 AP. AC and AR are DHCP client, DHCP relay device…
