Hello,
A D visa is, for a period of not more than three months from their initial date of validity, valid concurrently as a Schengen short-stay visa.
In other words your spouse may travel visa free in the Schengen area for the first three months. After that she will need a residence permit in Austria in order to be able to travel visa free in another Schengen state.
Regards.
