What is an advantage of using DHCP to dynamically assign IP addresses to hosts on large networks?
Servers are assigned an IP address only when a client requests a service.
Hosts can be assigned addresses from different subnets as the type network traffic changes.
Having leased IP addresses means that there are always more addresses available than there are devices.
Changes to the addressing scheme require only the DHCP subnet range to be reconfigured.
Pick the option that correctly lists the layers of the ISO (International Organization for Standardisation) networking model (in top down order)
