Prepare for the CCNP 642-821 BCRAN exam and gain a better, practical understanding of exam concepts

Experience how remote access concepts work in a real network with practice labs that walk you through their implementation

Review set-up guides that show you how to prepare a lab for study

Ready yourself for the new simulation-based questions on the CCNP exams
CCNP Practical Studies: Remote Access (CCNP Self-Study) prepares readers for the CCNP 642-821 BCRAN exam and for workplace challenges in implementing remote access network applications. Designed as a topic-by-topic guide of how to apply remote access concepts in a real network setting, this book is useful in preparing a CCNP candidate for the general exam questions by providing a better understanding of how remote access really works. It is also essential in preparing candidates for the new simulation-based questions that are on the Cisco certification exams. Finally, it serves anyone wanting a guide to real-world application of these concepts, regardless of certification interest.
Each chapter includes a review of the applicable technology, and guides the reader through implementation of the technology. This step-by-step process can be executed on a home-or office-based lab, a remote-accessible lab, some networking simulation software programs, or even as a stand-alone guide.
All of the topics on the new 642-821 BCRAN exam are covered, providing comprehensive exam preparation.
