Question #: 530
Topic #: 1
[All 200-301 Questions]


Refer to the exhibit. An engineer deploys a topology in which R1 obtains its IP configuration from DHCP. If the switch and DHCP server configurations are complete and correct, which two sets of commands must be configured on R1 and R2 to complete the task? (Choose two.)

  • A. R1(config)# interface fa0/0 R1(config-if)# ip helper-address 198.51.100.100
  • B. R2(config)# interface gi0/0 R2(config-if)# ip helper-address 198.51.100.100
  • C. R1(config)# interface fa0/0 R1(config-if)# ip address dhcp R1(config-if)# no shutdown
  • D. R2(config)# interface gi0/0 R2(config-if)# ip address dhcp
  • E. R1(config)# interface fa0/0 R1(config-if)# ip helper-address 192.0.2.2

Note that DHCP server is behind R2 and R1 needs IP via DHCP. Therefore, R2 needs to be a relay agent. On R1 interface, ip address dhcp and R2 inside interface, ip helper-address 192.168.100.100 (dhcp server). Answers are B and C.

BC are correct With these configurations in place: 1. R1, connected to the switch, will send out a DHCP request on its Fa0/0 interface. 2. R2's Gi0/0 interface, acting as a DHCP relay-agent, will receive the DHCP request. 3. R2 will forward the DHCP request to the DHCP server at IP address 198.51.100.100 (connected to R2's Gi0/1 interface). 4. The DHCP server will process the request and offer an IP address to R1. 5. R2 will relay the DHCP offer back to R1 through its Gi0/0 interface. 6. R1 will accept the DHCP offer and configure its Fa0/0 interface with the offered IP address. In summary, by configuring R2's Gi0/0 interface as a DHCP relay-agent using the ip helper-address command, we allow R1 to obtain its IP configuration from the DHCP server connected to R2. This way, the DHCP request can traverse the network from the client (R1) to the DHCP server (198.51.100.100) and back without requiring any manual IP configuration on R1.

Selected Answer: BC
B & C are correct The function of the DHCP relay agent is to forward the DHCP messages to other subnets so that the DHCP server does not have to be on the same subnet as the DHCP clients. The DHCP relay agent transfers DHCP messages from the DHCP clients located on a subnet without a DHCP server, to other subnets.

Is it that you can only have one helper address ?

the ip helper-address cmd must point to the ip of the dhcp server. oftentimes, it's a router. but here, it's an actual server!

Configuring DHCP relay agents We configure a DHCP relay agent only on the interface that is directly connected to a local subnet or a client. https://www.computernetworkingnotes.com/ccna-study-guide/how-to-configure-dhcp-relay-agent-on-cisco-routers.html

I think ZayaB mistaken for the ip helper-address command. It suppose to be "ip helper-address 198.51.100.100" on R2 Gi 0/0 and "ip address dhcp" on R1 Fa 0/0

act r1 as PC and add dhcp helper command to r2 and ip should be the dhcp server

I think there is an error in the answers. Refer to same question 413 on https://pupuweb.com/ccna-200-301-actual-exam-question-answer-dumps-5/2/ : it is correct there Instead of having I think here they put an error in the answer (confusion between R1 and R2 in the proposal with "ip dhcp address".

There is no need of DHCP relay if gi0/0 R2 have assigned dhcp address. So B and C are correct

BC Is correct, you must configure relay-agent on the router closest to the client (Not on the client). Bit of a tricky question to be honest
