Here is an example of how they might do it, but I believe your asking how it can be done and this should work.

First stage is to set-up 2 routes in the Global.asax

routes.MapRoute("WithQuestion", "questions/{id}/{name}", new { controller = "Questions", action = "Question", id = "1" });
routes.MapRoute("WithoutQuestion", "questions/{id}", new { controller = "Questions", action = "WithoutQuestion", id="1"});

Now in our Questions controller,

    public ActionResult Question(int id)
    {
        //Load the question as we have the name appended.
        // We could actually do a little validation here as well
        return View();
    }

    public ActionResult WithoutQuestion(int id)
    {
        //Load the question object
        //Generate the full URL and redirect
        return Redirect(FullURL)
    }

This is a very basic example but shows how you could do it.
