This subject provides students with an introduction to internetworks, covering communication protocols such as TCP/IP and sub-netting. Additionally, it familiarizes students with CISCO’s operating system, network fundamentals, LAN switching technologies, IPv4 and IPv6 routing technologies, WAN technologies, infrastructure services, infrastructure security, and infrastructure management. The core competency focuses on the understanding of internet and computer network architecture, operations of routers and switches in small networks, and the selection criteria for network devices and WAN technologies. The skill core competency emphasizes the ability to build simple LANs, perform basic configurations for routers and switches, implement IP addressing schemes, and configure/troubleshoot network devices.

Knowledge Core Competency Objectives:

1. Explain virtual private networks (VPNs) and tunneling.
2. Configure and troubleshoot broadband connections.
3. Describe devices and services supporting communications in data networks.
4. Understand the role of protocol layers in data networks.
5. Explain addressing and naming schemes in IPv4 and IPv6 environments.
6. Describe basic switching concepts and Cisco switch operation.
7. Understand the purpose and operation of routers, routing tables, and route lookup processes.
8. Explain VLANs, routing between VLANs, and dynamic routing protocols.
9. Configure and troubleshoot access control lists (ACLs) for IPv4 and IPv6 networks.
10. Configure and troubleshoot Dynamic Host Configuration Protocol (DHCP).
11. Configure and troubleshoot Network Address Translation (NAT) operations.
12. Configure and troubleshoot enhanced switching technologies.
13. Describe first hop redundancy protocols (HSRP) in a switched network.
14. Configure and troubleshoot wireless routers and clients.
15. Describe different WAN technologies.
16. Configure and troubleshoot tunneling operations.
17. Describe network architectures.

Skill Core Competency Objectives:

1. Design, calculate, and apply subnet masks and addresses in IPv4 and IPv6 networks.
2. Apply fundamental Ethernet concepts and build a simple Ethernet network.
3. Use Cisco CLI commands for basic router and switch configurations.
4. Utilize network utilities for verification and data traffic analysis.
5. Configure and troubleshoot static and default routing (RIP and RIPng).
6. Configure and troubleshoot Open Shortest Path First (OSPF) networks.
7. Monitor and troubleshoot network operations using syslog, SNMP, and NetFlow.
8. Configure and troubleshoot routers in complex routed IPv4 or IPv6 networks.
9. Manage Cisco IOS® Software licensing and configuration files.
