If return port only one then we can go for unconnected. More than one return port is not possible with Unconnected.  If more than one return port then go for Connected.

We can use more than one return port using Un-connected Lookup (Lookup override). 

As per my knowledger Un-connected Lookup is useful when we need to call the same lookup multiple times in the mapping.

Unconected lookups are used in cases where it is not necessary for all the rows to pass through it i.e. for each i/p row query need not be done.
