300-370 · Question #38
An engineer has run the debug dhcp packet enable command on the wireless LAN controller CLI. Which field contacts the IP address offered to the client?
The correct answer is D. yiaddr. In DHCP debug output, the 'yiaddr' field holds the IP address that the DHCP server offers to the client. This field is crucial for understanding which address a client will receive.

Why each option
In DHCP debug output, the 'yiaddr' field holds the IP address that the DHCP server offers to the client. This field is crucial for understanding which address a client will receive.
The 'siaddr' (Server IP address) field specifies the IP address of the next server in the bootstrap process, often the IP address of the DHCP server itself, not the client's offered address.
The 'ciaddr' (Client IP address) field contains the IP address of the client if the client already has an address, which is typically 0.0.0.0 during initial discovery.
The 'chaddr' (Client Hardware address) field contains the MAC address of the client's network interface, not an IP address.
The 'yiaddr' (Your IP address) field in a DHCP packet, as seen in debug output, contains the IP address that the DHCP server has offered to the client. This is a standard DHCP protocol field (RFC 2131) used for the address assignment process.
The 'giaddr' (Gateway IP address) field contains the IP address of the relay agent (gateway) if one is used, which forwards the DHCP packets between the client and the server.
