Straight from Cisco: official complete assessment, review, and practice for the newest CCNA ICND1 exam! The #1 selling CCNA preparation self-study guide, fully revised for every current CCENT/CCNA ICND1 exam objective In-depth, expert explanations of all protocols, commands, and technologies covered on the ICND1 exam Book and DVD packed with features to help you master today's challenging testing methods -- including scenario-based configuration questions that mimic the actual exam

Part 1: Networking Fundamentals. This part may be the least changed part in either book. Of the 5 chapters, only one chapter changes much, and those changes are pretty small. The content continues to have the same theme: introducing TCP/IP.   Part 2: Ethernet LANs. This part takes the previous edition’s 5 chapters and morphs them into 6 chapters. The re-org is mostly by choice to improve the flow, partly to shorten a few of the longer chapters that would grow due to new content. It also moves out the material about some key features (login security and banners) that move to the new Part 8, because the new content in part 8 is a better place to put that content. Part 2 is now a more focused part on how to build Ethernet LANs, introduces new content, and hopefully improves the clarity of how people first learn Ethernet.   Part 3: IPv4 addressing and subnetting. This part is substantively unchanged versus the previous edition. It adds some small content for the new specific exam topic that mentions multicast IP addressing (Chapter P3 1). (Note that I had already written a chapter on CIDR, speculating that the exam would include it, but since it does not, I have decided to publish the material but as a DVD-only appendix.)   Part 4: Implementing IPv4 Routing: Like parts 1, 2, and 3 mirror parts 1, 2, and 3 of the previous edition (respectively), this new part 4 mirrors the prior edition’s part 4. However, while parts 1 and 3 do not change much, part 4 changes quite a bit. All chapters include some new content. Chapter P4 3 replaces the old OSPF chapter with a new RIP chapter; I will use period editions and the DCICN cert guide for source material. These chapters also include new material for the deeper verbs in the exam topics for static IP routing and DHCP servers.   Part 5: IPv4 Design and Troubleshooting: This part is the first part that makes a noticeable departure from the prior edition (part 5). This part includes two chapters picked up (unchanged) from the prior edition (IP Subnetting Design and VLSM), and then picks up two IPv4 troubleshooting chapters from the prior edition of ICND2. The exam topics make a consistent mention of troubleshooting across the topics in ICND1, so these two chapters help strengthen the troubleshooting treatment throughout the topics in the book.   Part 6: Layer 3 Services: The new exam topics split ACL treatment between ICND1 (standard numbered and named) and ICND2 (extended numbered and named). As a tactic, this book will include a little more than the literal split of ACL topics for ICND1, and then repeat the two Part 6 ACL chapters into the new ICND2 book. ICND2 includes troubleshooting of all ACLs, so it needs some treatment of both standard and extended ACLs anyway. This part also includes the usual NAT chapter, improved for the new exam topics’ specific mention of NAT troubleshooting.   Part 7: IP Version 6: This part mostly copies from the previous edition Part 7 of the same name. Two notable changes occur here for content. First, the ICND1 exam topics no longer includes OSPFv3 (OSPF for IPv6), which was the only IPv6 routing protocol in ICND1. So, former chapter 29 (now Chapter P7 5) removes the OSPF content. The mention of IPv6 static routing in the new exam topics expands, both in small details and with the addition of the troubleshoot verb. As a result, Chapter P7 5 receives most of the re-work. The other 4 chapters in this part are mostly unchanged.   Part 8: Infrastructure Management: This part holds most of the topics that did not exist at all in the previous ICND1 exam topics, along with related picked-up material to make it a cohesive whole. The four chapters contain roughly 1.5 chapters of picked up material, plus 2.5 chapters of new material. The topics include: Chapter P8 1, about Syslog, NTP, CDP, and LLDP; P8 2, about device hardening; P8 3, about config and IOS file management, mostly picked up from ICND2; and P8 4, a heavily-revised version of the former ICND2 chapter about IOS licensing.
