What are the two minimum required components of a DHCP binding? (Choose two.)
The correct answer is C. a hardware address D. an IP address. A DHCP binding is a record that maps a specific IP address to a unique hardware (MAC) address, associating the two. These two components are the minimum required for a DHCP server to consistently assign the same IP address to a particular network client.

Why each option
A DHCP binding is a record that maps a specific IP address to a unique hardware (MAC) address, associating the two. These two components are the minimum required for a DHCP server to consistently assign the same IP address to a particular network client.
A DHCP pool is a range of IP addresses available for assignment, but it's the source of the IP, not a component of a single binding.
An exclusion list specifies IP addresses that should not be assigned by DHCP, which affects the pool but is not part of a binding itself.
A hardware address (MAC address) uniquely identifies a network interface and is used by the DHCP server to identify the client requesting an IP address.
An IP address is the network layer address that the DHCP server assigns to the client. The binding explicitly links this IP address to a specific hardware address.
An `ip-helper` statement is used on a router to forward DHCP broadcast requests to a DHCP server on a different subnet, facilitating DHCP operation across segments, but it's not a component of the DHCP binding record.
