Refer to the exhibit. A network administrator has added a new subnet to the network and needs hosts on that subnet to receive IPv4 addresses from the DHCPv4 server.
What two commands will allow hosts on the new subnet to receive addresses from the DHCP4 server? (Choose two.)
- R2(config-if)# ip helper-address 10.2.0.250
- R1(config)# interface G0/1
- R1(config-if)# ip helper-address 10.2.0.250
- R1(config)# interface G0/0
- R1(config-if)# ip helper-address 10.1.0.254
- R2(config)# interface G0/0
Answers Explanation & Hints: The new subnet is connected to router R1 on interface G0/0, so the first step is to configure the helper address on this interface using the “ip helper-address” command with the IPv4 address of the DHCPv4 server (10.2.0.250). This will allow DHCPv4 broadcast messages from the new subnet to be forwarded to the DHCPv4 server.
The second step is to configure the same helper address on the interface of R2 that is connected to R1 (G0/1). This is not explicitly shown in the exhibit, but it is a common practice to configure the helper address on the interface closest to the DHCPv4 server. This will allow DHCPv4 broadcast messages from R1 to be forwarded to the DHCPv4 server.
Therefore, the correct commands are:
R1(config)# interface G0/0 R1(config-if)# ip helper-address 10.2.0.250
