The iCertify flash cards are divided into four main subjects:

- Fundamentals
- LANs
- Internetworks
- Security

iCertify Fundamentals tests your knowledge of network layers (OSI and TCP/IP), network devices, and how packets get forwarded across an internetwork. It also gives you practice converting between binary, hex, and decimal.

iCertify LANs is where you will prove that you are a switch guru. Test your ability to configure, verify, and troubleshoot VLANs. Prepare to answer questions on the real exam about spanning tree. iCertify LANs also covers wireless networks.

iCertify Internetworks delves into IP addressing, routers, routing, and WANs. Test your ability to quickly design and implement IP addressing schemes, including subnetting, subnet masks, and VLSM. Practice answering questions about IPv6, OSPF, EIGRP, Frame Relay, and PPP.

What kind of network engineer would you be if you couldn't identify security threats to a network and describe and implement methods to mitigate those threats? Use the iCertify Security flash cards to prepare for those topics on the CCNA test. iCertify Security covers NAT, VPNs, and ACLs.
