CISCO CCDA 640-864 Chapter 1: Network Design Methodology

Budget and personnel limitations are examples of organizational constraints. Organizational constraints refer to the limitations or restrictions that an organization may face in terms of resources, budgets, personnel, or other factors that can impact its operations and decision-making. In this case, the budget and personnel limitations act as constraints that the organization must work within, influencing its ability to allocate funds and human resources effectively.

The top-down design approach starts the design from the application layer.

Improving network response time and reliability are examples of technical goals. Technical goals refer to specific objectives that an organization sets to achieve in order to enhance the performance, efficiency, and effectiveness of its technical systems or infrastructure. In this case, the aim is to enhance the speed and reliability of the network, which aligns with the technical goals of the organization.

The primary sources of network audits are existing documentation, management software, and new management tools.

Prototypes and pilots are used as soon as the Design phase is complete but before the Implementation phase. This means that after the design has been finalized, prototypes and pilots are created to test and validate the design before it is fully implemented. This allows for any necessary adjustments or improvements to be made based on the feedback and results from the prototypes and pilots, ensuring a smoother implementation process.

The correct order of the six phases of PPDIOO is Prepare, Plan, Design, Implement, Operate, Optimize. This order ensures that the necessary preparations are made before moving on to the planning phase. Once the plan is in place, the design phase takes place to create a detailed plan for implementation. After implementing the plan, the network or system is operated, and any necessary optimizations are made to improve its performance.

Network resiliency and control occurs in the Network Services layer

Presence occurs under Collaboration Services.

The project plan should be updated during all phases of the PPDIOO life cycle.

NetFlow provides extremely granular and accurate traffic measurements and a high-level collection of aggregated traffic. The output of NetFlow information is displayed via the show ip cache flow command.

Collaboration, data center/virtualization, and borderless network are the three architectures for the enterprise.

Removal of borders, virtualization, and growth of applications are technology forces.

The PPDIOO methodology has three steps.
