Designing Cisco Network Service Architectures (ARCH 642-874)

Introduction

The design of the Cisco Service Network Architectures (ARCH), second edition, focuses on how to perform the design, through detailed and a network infrastructure. This design is compatible with intelligent network services solutions for efficient network performance, scalability and network availability. This book allows readers, applying solid Cisco network solution models and best design practices to provide interconnection solutions viable and stable business networks. In addition, the book was written to help candidates prepare for the project examination Cisco Network Service Architectures (642-873 ARCH). This exam is one of the requirements for certification CHRC. This exam tests a candidate's knowledge on the latest developments in design and network technologies, including network infrastructure, intelligent network services and converged network solutions.

Since the first edition was published in 2004, during ARCO has changed to reflect the new exam requirements. This led to the immediate need to update this exam preparation. Readers of the previous edition of the design of the Cisco Network Architectures (ARCH) can use this text to update their knowledge and skills.

Goals of This Book
Upon completing this book, you will be able to meet these objectives:
 . Introduce the Cisco Service-Oriented Network Architecture (SONA) framework, and explain how it addresses enterprise network needs for performance, scalability, and availability
 . Describe how the Cisco Enterprise Architectures are used in the SONA framework for designing enterprise networks
 . Create intermediate and detailed enterprise campus network, enterprise edge, and remote infrastructure designs that offer effective functionality, performance, scalability, and availability
 . Create conceptual, intermediate, and detailed intelligent network service designs for network management, high availability, security, quality of service (QoS), and IP multicast
 . Create conceptual, intermediate, and detailed virtual private network (VPN) designs
 . Create conceptual, intermediate, and detailed voice over wireless network designs
