-- | Associates a set of DHCP options (that you've previously created) with the
-- specified VPC, or associates no DHCP options with the VPC. After you
-- associate the options with the VPC, any existing instances and all new
-- instances that you launch in that VPC use the options. You don't need to
-- restart or relaunch the instances. They automatically pick up the changes
-- within a few hours, depending on how frequently the instance renews its
-- DHCP lease. You can explicitly renew the lease using the operating system
-- on the instance. For more information, see DHCP Options Sets in the Amazon
-- Virtual Private Cloud User Guide.
