Is the subdomain, sub.example.com,  a separate (child) zone?  Or is it 
simply part of the same zone on the same server(s) as the parent domain, 
example.com?

If you are breaking the sub-domain, sub.example.com, out into it's own 
zone, then yes you need to delegate via NS records.  If you aren't 
breaking the sub-domain into it's own zone, I see no reason for NS records.

Remember that zones do not have to line up with (sub)domain boundaries.
