    Study Notes

    Networks in Daily Life

    • Networks support many aspects of our daily lives, including communication, information, and entertainment.

    Network Evolution

    • Cisco keeps updating its network infrastructure to accommodate the constant evolution of networks.

    Business Forces

    • Government regulations and industry regulations are two significant business forces affecting decisions for the enterprise network.
    • Not mentioned as a business force affecting decisions is personal preferences.

    Industry Regulations

    • Companies need to meet industry regulations regarding their network infrastructure to ensure security, compliance, and reliability.

    Network Architecture

    • One factor that can affect network architecture is the type of application or service being used.

    Competitive Edge

    • Companies need to use technology to maintain a competitive edge and stay ahead in the market.

    Strategy and Analysis

    • The main focus of the Strategy and Analysis process is to identify business goals, objectives, and requirements.

    Technology Forces

    • Technology forces affecting decisions for the enterprise network include technology advancements, market trends, and customer needs.

    Virtualization

    • Virtualization allows for the reduction of hardware, power consumption, and management effort.

    Design Process

    • The purpose of the Design process is to create a detailed and specific design for the network, including the selection of devices and technologies.

    Organizational Goals

    • A key goal for almost all organizations is to increase productivity, efficiency, and customer satisfaction.

    Build Process

    • The Test and Quality Assurance phase involves confirming if the solution meets requirements for availability, security, reliability, and performance.

    Deployment Process

    • The primary objective of the Deployment process is to install and configure the network solution.

    IT Optimization

    • IT optimization areas include infrastructure, applications, and business processes, but not personal preferences.

    Network Access

    • Remote access needs to be enabled from branch offices, teleworkers, and mobile devices.

    Network Assessment

    • The network assessment is done in the Strategy and Analysis process to determine gaps in the network operation team's ability to support new technologies.

    Customer Needs

    • Customers continue to ask for networks that are faster, more reliable, and more secure.

    Strategy and Analysis

    • The Strategy and Analysis process aims to optimize the network infrastructure, applications, and business processes.

    Cisco Network Lifecycle

    • The three phases of the updated Cisco network lifecycle are Plan, Build, and Operate.

    Cisco Design Lifecycle

    • The Strategy and Analysis process is included in the 'Plan' phase of the Cisco Design Lifecycle.
    • The focus of the 'Build' phase is to design and implement the network solution.
    • The Operate phase involves processes for solution support and operations management.

    Cisco PBM

    • PBM stands for Cisco Powered Business Model.

    Cisco Design Lifecycle

    • The Network Assessment and Design processes are included in the 'Plan' phase, but not the Deployment process.

    Top-Down Design

    • A top-down design approach entails designing the network from the highest level (applications and services) down to the lowest level (devices and technologies).
    • In a top-down design approach, network devices and technologies are selected after the application and service requirements have been defined.
    • To complete a top-down design, the network architecture and design are developed based on the application and service requirements.

    Network Testing

    • It is important to test network designs using a pilot or prototype network to ensure that the design meets the requirements and works as expected.

    OSI Layers

    • The correct sequence in a top-down design process regarding OSI layers is to start with the application layer and work down to the physical layer.

    Network Adaptation

    • It is essential to adapt the network and physical infrastructure to the network application's requirements to ensure that the network can support the application and provide the required level of performance and reliability.
