      Hooray!
      Yep, a few. Check out the Questions option at the top. There are 3 or 4 types of IP subnetting questions there, with subnet speed as one of those. Enjoy!

      Mahii,
      I’m not familiar with lab pricing for products from Cisco. But here are some suggestions:
      On this blog, and my similar CCNA blog (blog.certskills.com/ccna), go to the hands-on tab. All posts there are labs. In particular, “config labs” may be what you’re looking for. Totally free.
      Go to the Cisco learning networking (learningnetwork.cisco.com) and search for “free CCNA study” within the CCNA study group. The topic of free study tools comes up there from time to time, and is well discussed there.
      Hope this helps.
      Wendell
