Advanced network design has become a challenge in the last few years because modern networks are complex and they are critical to business operations. The challenge for design engineers is maintaining the skills necessary in response to the internetworking industry’s constant and rapid changes, one of which is designing robust, reliable, and scalable networks.
The Designing Cisco Network Service Architectures (ARCH) exam is the core exam required for Cisco Certified Design Professional (CCDP) certification, along with the Implementing Cisco IP Routing (ROUTE) and Implementing Cisco IP Switched Networks (SWITCH) exams. This book provides the latest developments in network design and technologies, including network infrastructure, intelligent network services, and converged network solutions. Objectives for the ARCH exam, according to the official blueprint, include the following:
Designing advanced Enterprise Campus networks
- Design high availability for Enterprise networks
- Design Layer 2 and Layer 3 Campus infrastructures using best practices
- Describe Enterprise network virtualization considerations
- Design infrastructure services, including voice, video, and QoS
- Identify network management capabilities in Cisco IOS software
Designing advanced IP addressing and routing solutions for Enterprise networks
- Create summarizable and structured addressing designs
- Create stable and scalable routing designs for EIGRP, OSPF, and BGP for IPv4
- Describe IPv4 multicast routing
- Create IPv4 multicast services and security designs
- Describe IPv6 for Campus design considerations
Designing WAN services for Enterprise networks
- Describe Layer 1, Layer 2, and Layer 3 WAN connectivity options, including optical networking, Metro Ethernet, VPLS, and MPLS VPNs
- Describe IPsec VPN technology options
- Evaluate WAN service provider design considerations, including features, SLAs, and WAN backup
- Create site-to-site VPN designs with appropriate technologies, scaling, and topologies
Designing an Enterprise Data Center
- Describe Enterprise Data Center best practices
- Describe the components and technologies of a SAN network
- Describe integrated fabric designs using Nexus technology
- Describe network and server virtualization technologies for the Enterprise Data Center
- Create an effective e-commerce design
- Design a high availability Data Center network that is modular and flexible
Designing security services
- Create firewall designs
- Create NAC appliance designs
- Create IPS/IDS designs
- Create remote access VPN designs for the teleworker
The major objective of this book is to introduce the Cisco Borderless Network architectural framework in the context of meeting the Enterprise network’s needs for performance, scalability, availability, and security. This book also explains how to create detailed Enterprise Campus, Enterprise Edge, and remote infrastructure designs that offer effective functionality, performance, scalability, and availability, as well as how to create detailed intelligent network services and Virtual Private Network designs.
