CCNA Exploration 1. Network Fundamentals

This course introduces the architecture, structure, functions, components, and models of the Internet and other computer networks. It uses the OSI and TCP layered models to examine the nature and roles of protocols and services at the application, network, data link, and physical layers. The principles and structure of IP addressing and the fundamentals o f Ethernet concepts, media, and operations are introduced to pro vide foundation for the curriculum. Labs use a "model Internet" to allow students to analyze real data with out affecting production networks. Packet Tracer (PT) activities help students analyze protocol and network operation and build small networks in a simulated environment. At the end of the course, students build simple LAN topologies by apply in basic principles of cabling, performing basic configurations of network devices such as routers and switches, and implementing IP addressing schemes.

Students who complete Network Fundamentals will be able to perform the following tasks:

• Explain the importance of data networks and the Internet in supporting business communications and every day activities
• Explain how communication works in data networks and the Internet
• Recognize the devices and services that are used to support communications across an Internet work
• Use network protocol models to explain the layers of communications in data networks
• Explain the role of protocols in data networks
• Describe the importance of addressing and naming schemes at various layers of data networks
• Describe the protocols and services provided by the application layer in the OSI and TCP/IP models and describe how this layer operates in various networks
• Analyze the operations and features of transport layer protocols and services
• Analyze the operations and feature of network layer protocols and services and explain the fundamental concepts of routing
• Design, calculate, and apply subnet masks and addresses to fulfill given requirements
• Describe the operation of protocols at the OSI data link layer and explain how they support communications
• Explain the role of physical layer protocols and services in supporting communications across data networks
• Explain fundamental Ethernet concepts such as media, services, and operation
• Employ basic cabling and network designs to connect devices in accordance with stated objectives
• Build a simple Ethernet network using routers and switches
• Use Cisco command-line interface (CLI) commands to perform basic router and switch configuration and verification
• Analyze the operations and features of common application layer protocols such as HTTP, Domain Name System (DNS), Dynamic Host Configuration Protocol (DHCP), Simple Mail Transfer Protocol (SMTP), Telnet, and FTP
• Utilize common network utilities to verify small network operations and analyze data traffic
