Reading Time: 1 minute Neil Anderson, from Flackbox, has build an amazing free Cisco CCNA Lab Guide recently which can be used to pass the CCNA exam or as a configuration reference for Cisco routers and switches. There’s a few free guides online but they all cover old out of date exam topics and aren’t great quality, but this is guide really complete (350+ pages), up to date, with good quality and simple, which people can use completely for free.
