Refer to the exhibit. Router DHCP is configured to lease IPv4 and IPv6 addresses to clients on ALS1 and ALS2. Clients on ALS2 receive IPv4 and IPv6 addresses. Clients on ALS1 receive IPv4 addresses. Which configuration on DSW1 allows clients on ALS1 to receive IPv6 addresses?
A. DSW1 (config-if)# ipv6 helper address 2002:404:404::404:404
B. DSW1 (config)#ipv6 route 2002:404:404::404:404/128 FastEthernet 1/0
C. DSW1 (dhcp-config)# default-router 2002:A04:A01::A04:A01
D. DSW1 (config)# ipv6 dhcp relay destination 2002:404:404::404:404 GigabitEthernet 1/2
c if the other clients receive both addresses then the relay agent is already configured
D
The answer D is correct with syntax. However, it has to be configured in the interface mode which is “DSW1 (config-if)#”, but not “DSW1 (config)#”
correct answer is D
