Similar but a little different. NET+ has a slightly wider scope in terms of technologoies and vendors whereas ICND is of course Cisco specific. Some wuld argue the NET+ is not as in-depth as the ICND which is true, but you'll be expected to know less about more, if that makes any sense. If you're up to the level of being able to have a good stab at passing ICND1 then just get a NET+ book (they're not that expensive), spend a few weeks and you'll probably ace it
