The first up is howtonetwork.net's free labs. There is 101 free labs and they are great. Simple instructions, easy to blow through for practice and to get your pace up to exam standards. They are "unanswered" labs (challenge labs I guess they're called) so, once your finished, connectivity will tell you if you've done the lab correctly.
If you need the answers or a walk through for the labs, you can purchase a book of all 101 labs for $297.00 which includes lab videos and other tid bits (the book alone is $85.11 at amazon). A bit more reasonable, you can also become a platinum member of the site for $30.00 a month and then have access to lab walk throughs. I think the member route is a lot more economically viable and the site offers some nice features like a 30 minute audio cram review, included rack time, a CCNA study book, amongst other things. How to network.net are the folks that put out the site subnettingquestions.com.
