You are a junior network engineer for a financial company, and the main office network is experiencing network issues. Troubleshoot the network issues.
Router R1 connects the main office to the Internet, and routers R2 and R3 are internal routers.
NAT is enabled on router R1.
The routing protocol that is enabled between routers R1, R2 and R3 is RIPv2.
R1 sends the default route into RIPv2 for the internal routers to forward Internet traffic to R1.
You have console access on R1, R2 and R3 devices. Use only show commands to troubleshoot the issues.

Examine the DCHP configuration between R2 and R3, R2 is configured as the DHCP server and R3 as the client. What is the reason R3 is not receiving the IP address via DHCP?
Correct Answer: B
Explanation/Reference:
Explanation:
First we should check which interface on R3 that is connected to R2 via the "show run" command.

From the description we learn interface E0/1 is connected to R2. Use the "show ip interface brief" command to verify the IP address of this interface.

Therefore we can conclude this interface does not have any IP address and there is no configuration on this interface (except the "description Link to R2" line).
If R3 wants to receive an IP address from R2 via DHCP, interface E0/1 should be configured with the command "ip address dhcp" so the answer "DHCP is not enabled on this interface" is correct.
