CCDA Notes Identifying Voice Networking Considerations
CCDA Notes Identifying Voice Networking Considerations Many of today’s enterprise network designs must accommodate the transmission of voice traffic in addition to data traffic. The transmission of voice over a data network is often referred to as Voice over IP (VoIP). The inclusion of VoIP in a network design typically requires integration with existing telephony services and … [Read more...]
CCDA Notes IP Addressing and Routing Protocols
CCDA Notes IP Addressing and Routing Protocols Efficiently assigning IP addresses to your network is a critical design decision, impacting the scalability of the network and the routing protocol that can be used. This section reviews IP Version 4 addressing, introduces IP Version 6 addressing, and analyzes characteristics of various routing protocols. IP Addressing Before … [Read more...]
CCDA Notes Remote Connectivity Design
CCDA Notes Remote Connectivity Design Remote office locations, such as branch offices or the homes of teleworkers, connect to the enterprise campus via the enterprise edge and enterprise WAN. When selecting an appropriate WAN technology to extend to these remote locations, design considerations include ownership (that is, private, leased, or shared ownership) of the link, … [Read more...]
CCDA Notes Exploring Basic Campus and Data Center Network Design
CCDA Notes Exploring Basic Campus and Data Center Network Design The multilayer design strategy uses a modular approach, which adds scalability to a design. This section examines how the multilayer design approach can be applied to both the enterprise campus and the enterprise data center. Understanding Campus Design Considerations As illustrated, an enterprise campus might … [Read more...]
CCDA Notes Modular Network Design
CCDA Notes Modular Network Design For many years, Cisco recommended a three-layer network design model: access layer, distribution layer, and core layer. However, to provide for enhanced scalability and flexibility, Cisco later introduced the Cisco Enterprise Architecture, which categorizes enterprise networks into six modules. The three layers of the Cisco Service Oriented … [Read more...]
