Does Unconstrained plan respect lead time processing and lead time supp for make item and buy item ?

1. If I were to put processing lead time and lead time supplier for make and buy item in unconstrained supply plan would the plan still generate planned order without calculating my lead time data?
2. If I have constrained supply plan would the plan still recommend plan order even if the lead time won't fulfill my order demand ?

example 7 days of processing lead time and the sales order due today, what behavior I would expect from both constrained and unconstrained plan ?

And are the data for lead time are from PIM ?
