Class Activity 1.4.1.1: Borderless Innovations - Everywhere
You are the network administrator for your small- to medium-size business. Borderless network services interest you as you plan your network’s future.
While planning for network policies and services, you realize that your wired and wireless networks need manageability and deployment design.
Therefore, this leads you to consider the following Cisco borderless services as possible options for your business:
- Security: TrustSec
- Mobility: Motion
- Application performance: App Velocity
- Multimedia performance: Medianet
- Energy management: EnergyWise
Packet Tracer Activity 1.4.1.2: Skills Integration Challenge
This Packet Tracer Activity provides an opportunity to review skills from previous coursework.
Your business has just expanded into a different town and needs to expand its presence across the Internet. You are tasked with completing the upgrades to the enterprise network, which includes dual-stacked IPv4 and IPv6 as well as a variety of addressing and routing technologies.
Packet Tracer Activity 1.4.1.3: Skills Integration Challenge - EIGRP
You are a network technician new to a company that has lost its last technician in the middle of a system upgrade. You are tasked with completing upgrades to the network infrastructure that has two locations. Half of the enterprise network uses IPv4 addressing, and the other half uses IPv6 addressing. The requirements also include a variety of routing and switching technologies.
The structured engineering principles of good network design include hierarchy, modularity, resiliency, and flexibility.
A typical enterprise hierarchical LAN campus network design includes the access layer, distribution layer, and the core layer. In smaller enterprise networks, a “collapsed core” hierarchy, where the distribution layer and core layer functions are implemented in a single device, can be more practical. The benefits of a hierarchical network include scalability, redundancy, performance, and maintainability.
A modular design that separates the functions of a network enables flexibility and facilitates implementation and management. The basic module blocks that are connected by the core include the access distribution block, the services block, the data center, and the enterprise edge. The Cisco Enterprise Architecture modules are used to facilitate the design of large, scalable networks. The primary modules include the enterprise campus, enterprise edge, service provider edge, enterprise data center, enterprise branch, and enterprise teleworker.
