Cisco CCNA 4 — Designing and Supporting Computer Networks
In Cisco CCNA 4, I studied network requirements, IP addressing, campus and WAN prototypes, application effects, network design and technical proposals.
Cisco CCNA 4 brought the earlier networking topics together from a design and support perspective. I worked through requirements, characterization of an existing network, IP-addressing decisions, campus and WAN prototypes, application effects and proposal preparation as stages of one design process.
The course covered:
- Identifying Network Requirements
- Introduction to Network-Design Concepts
- Using IP Addressing in Network Design
- Creating the Network Design
- Building a Campus-Network Prototype
- Characterizing the Existing Network
- Preparing a Proposal
- Identifying the Effect of Applications on Network Design
- Building a WAN Prototype
For me, this final CCNA stage marked the transition from learning individual networking technologies to relating requirements to concrete network-design decisions.
