I think this is what it would look like in service dhcp server. I left some comments to explain my thinking a bit, and I tried to make it as flexible as possible (for example the way match options are strings, so future DHCP options can be supported as soon as ISC supports them):

rule 10 {

match option "agent.circuit_id" value "Vlan200" # This could match any option (ex: dhcp-client-identifier)
}
}
class GUEST_MAP {
rule 10 {
action permit
match option "agent.circuit_id" value "Vlan240"
}
}
