sql server - Clustered and non-clustered index

Interviewer asked me the difference between clustered and non-clustered index and than moved further into it and asked one more question - When a table has a clustered index and a non-clustered index, do the non-clustered index still points to the data row in the table? I said yes, and immediately I thought it is wrong. Does it points towards the data row that is ordered by clustered index or the original data rows? Can someone throw some light on this please.
