    Are you planning on taking the Cisco 100-101 CCENT ICND1 exam? I

    Are you planning on taking the Cisco 100-101 CCENT ICND1 exam? If you are, then this book is for you! Authors Michael Valentine and Keith Barker, have done an outstanding job of writing a second edition of a book that will help ensure your success in passing the 100-101 ICND1 exam.




    Authors Valentine and Barker, begin by introducing the basics of networking, and point out some of the concepts that are tested on the ICND1 100-101 exam. Then, the authors review the Open Systems Interconnection (OSI) model and compare it to the TCP/IP model. They continue by looking at the relationship between the IP address and subnet mask in more detail; as well as, how it can be manipulated for more efficient network functionality by using route summarization. Then, the authors introduce you to Cisco equipment. They then show you how to secure your Cisco router or switch. Next, the authors introduce the concepts and modes of Layer 2 switching and physical layer connectivity between switches. They continue by providing an overview of one of the largest and most challenging topics on the CCENT exam: Basic Routing. Then, the authors take an inside look at the details of packets and frames, as they move across the network. Next, they show you how to use packet filters to filter traffic coming from one network into another. The authors also examine the three main implementations of NAT in Cisco routers, along with the applications, advantages, and disadvantages of the NAT service; and, finally the configuration commands to implement, verify, and troubleshoot it. Finally, they continue by troubleshooting and correcting common problems associated with IP addressing and host configurations. 




    This most excellent book helps you understand and appreciate the subjects and materials that you need, in order to pass the Cisco certification exams. In fact, the materials in this great book have been prepared with a very clear focus on testable concepts, configurations, and skills.
