When studying for your Cisco CCNA, CCNP, or CCIE exam, you've got a powerful online weapon at your disposal. It's Cisco Connection Documentation, found at www.cisco.com/univercd. This site contains product, code, and protocol documentation for all Cisco products.

Many exam candidates really don't start using this powerful tool until they're studying for their more advanced exams.

It comes in handy for finding default values that Cisco really enjoys asking about on exams, and the protocol documentation found there can help you study as well.

The site can be a little overwhelming for newcomers, but it's actually easy to navigate. On the site's homepage, you're presented with a list of products and several drop-down menus. To get started, I suggest you choose Cisco IOS Software
