Refer to the exhibit. The DHCP server is configured with a DHCP pool for each of the subnets represented. Which command must be configured on switch SW1 to allow DHCP clients on VLAN 10 to receive dynamic IP addresses from the DHCP server?
When configuring the ip helper-address command on the switch, you should use the IP address of the router's interface that is directly connected to the subnet where the client devices reside, not the default router IP.:
The ip helper-address command tells the switch (or router) where to forward DHCP requests.
So IP helper-address command must be on the Default-Gateway of our respective VLAN. So in this scenario our host is in VLAN 10 has a pool Created named Net10, we have two DHCP servers created for VLAN 10 and VLAN 20 Net 20 (READ THE commands inserted on R1 not the 192.168.20.2 IP address that you see on the picture , that's a trap ). We can't tell PC 1 get your IP address from DHCP Server on VLAN 20 because then you will have no internet connectivity because the our port F0/1 is in VLAN 10! We need our PC to get a valid IP address from 192.168.10.2 Then it will have connectivity on Port FastEthernet 0/1 access port vlan 10.
Right answer D, 192.168.10.2 THIS is where we want our broadcast Discovery message to go as a UNICAST , to this address, because we have a DHCP server for each VLAN !!!
Ignore my above message, the right answer is 192.168.20.2 . our SW is the DG to our PC , we put there the IP helper then it sends it to another network (that is normal) and we receive an Offer with 192.168.10.x IP back .
Final answer C .
D can't be answer, because 192.168.10.2 address is not given for any interface, it is just configured on router. We don't know on which interface it is given, since we have only one connected interface, which is even access port. But 192.168.20.2 is given for router interface.
This is why I pick C
Ok this going to be long. Correct me if I am wrong please. 1st we have a multilayer switch with interswitch vlan routing going on.
Ip helper should be applied on the routing interface closest to the clients, because the discover messages cant pass layer 3 interface without ip helper. On the switch we have Interface VLAN 10 192.168.10.1. So any device trying to exit the broadcast domain from vlan 10 has to go thru this interface. So that's where we should apply the IP Helper command on. Then we look for the IP Address of the DHCP Server and it looks like the IP Address of the server is Int g0/0 192.168.20.2. So the correct answer should be SW1(config)int vlan 10 , SW1(config-if)ip helper-address 192.168.20.2
It is C. You are thinking of the default gateway, we need the DHCP server address which is 192.168.20.2. The exhibit with the long output is meant to throw us off, just look at the topology diagram and it is there. If we only needed 192.168.10.2 for DHCP for VLAN 10, then we would not need an IP helper address.
True. I didn't even look at the output, only at the topology to be honest.
