Cisco CCT Routing and Switching 100-490 Course

Lesson 1 • Data Transmission and Media Types

Examines copper, fibre, and wireless media along with their electrical and optical properties. Prepares students to select and identify physical media in lab environments.

Lesson 2 • Introduction to Computer Networks

Covers network types, topologies, and basic communication concepts. Establishes the vocabulary needed for all subsequent networking topics.

Lesson 3 • The OSI Reference Model

Explains all seven OSI layers and their specific roles. Provides the conceptual framework for troubleshooting and protocol analysis throughout the course.

Lesson 1 • Navigating Cisco IOS CLI

Teaches IOS exec modes, help system, and command syntax conventions. Students develop fluency in CLI navigation essential for all configuration tasks ahead.

Lesson 2 • Connecting to Cisco Devices

Covers console, auxiliary, and out-of-band management connections. Students gain hands-on ability to establish initial device access using terminal emulation software.

Lesson 3 • Cisco Router and Switch Hardware

Identifies physical components of Cisco routers and switches including ports, modules, and LEDs. Grounds students in hardware recognition required for field technician tasks.

Lesson 4 • IOS File System and Boot Process

Explains flash memory, NVRAM, RAM, and the IOS boot sequence. Students understand where configurations and images are stored for maintenance and recovery tasks.

Lesson 1 • VLAN Concepts and Configuration

Introduces VLANs as logical network segments and covers creation and port assignment. Students configure access ports and verify VLAN membership on Cisco switches.

Lesson 2 • Switch Forwarding and MAC Table

Details how switches learn MAC addresses, build the CAM table, and forward frames. Students trace frame paths to understand switching behaviour before configuring VLANs.

Lesson 3 • Ethernet and MAC Addressing

Explains Ethernet frame structure, MAC address format, and address types. Connects physical addressing to switch forwarding decisions covered in later sections.

Lesson 4 • Trunk Links and 802.1Q Tagging

Covers trunk port operation, 802.1Q frame tagging, and native VLAN behaviour. Students configure trunk links to carry multiple VLANs between switches.

Lesson 1 • IPv6 Addressing Fundamentals

Introduces IPv6 address format, types, and abbreviation rules. Students identify IPv6 address categories and understand coexistence with IPv4 in modern networks.

Lesson 2 • Variable-Length Subnet Masking

Introduces VLSM to allocate address space efficiently across multiple subnets. Students design VLSM schemes that minimise address waste in real network scenarios.

Lesson 3 • IPv4 Address Structure

Explains binary representation, address classes, and public vs. private ranges. Provides the mathematical foundation required for all subnetting calculations.

Lesson 4 • Configuring IP Addresses on Cisco Devices

Applies addressing knowledge to configure IPv4 and IPv6 on router interfaces and switch SVIs. Students verify connectivity using ping and show interface commands.

Lesson 1 • How Routers Forward Packets

Covers routing table structure, longest-prefix match, and administrative distance. Students understand the decision logic routers use before configuring any routes.

Lesson 2 • Default Routes and Stub Networks

Explains the default route as a gateway of last resort and its use in stub networks. Students configure default routes to provide Internet-bound forwarding on edge routers.

Lesson 3 • Static Route Configuration

Teaches ip route syntax for next-hop and exit-interface static routes. Students configure and verify static routes connecting multiple network segments.

Lesson 4 • Inter-VLAN Routing

Covers router-on-a-stick and Layer 3 switch methods for routing between VLANs. Students configure subinterfaces and SVIs to enable inter-VLAN communication.

Lesson 1 • OSPF Single-Area Configuration

Covers OSPF router ID, network statements, and neighbour adjacency formation. Students configure and verify single-area OSPF on a multi-router topology.

Lesson 2 • Troubleshooting Dynamic Routing

Diagnoses neighbour adjacency failures and missing routes using show and debug commands. Students apply systematic steps to restore dynamic routing in a broken topology.

Lesson 3 • Dynamic Routing Protocol Overview

Compares distance-vector, link-state, and hybrid protocols and their convergence behaviours. Students select appropriate protocol types based on network size and design requirements.

Lesson 4 • Routing Protocol Metrics and Selection

Explains how each protocol calculates metrics and how administrative distance resolves conflicts. Students predict route selection outcomes when multiple protocols are present.

Lesson 1 • DHCP Server and Client Configuration

Covers DHCP pool creation, exclusions, and relay agent configuration on Cisco routers. Students configure a router as a DHCP server and verify client address assignment.

Lesson 2 • Configuring NAT on Cisco Routers

Applies NAT concepts to configure static NAT, dynamic NAT, and PAT using IOS commands. Students verify translations using show ip nat translations and debug commands.

Lesson 3 • Configuring and Applying ACLs

Covers numbered and named ACL syntax and interface application direction. Students configure ACLs to permit or deny specific traffic and verify results with show commands.

Lesson 4 • Access Control List Fundamentals

Introduces standard and extended ACL logic, wildcard masks, and implicit deny. Students understand ACL processing order before applying lists to router interfaces.

Lesson 1 • Structured Troubleshooting Methodology

Introduces top-down, bottom-up, and divide-and-conquer troubleshooting approaches. Students select the appropriate method based on fault symptoms and network topology.

Lesson 2 • Layer 3 Diagnostics and Tools

Applies ping, traceroute, and show ip route to isolate Layer 3 connectivity failures. Students trace packet paths and identify missing or incorrect routes causing outages.

Lesson 3 • Layer 1 and Layer 2 Diagnostics

Uses show interfaces, CDP, and LLDP to identify physical and data link layer faults. Students diagnose cable errors, duplex mismatches, and VLAN misconfigurations.

Lesson 4 • Password Recovery and Device Reset

Explains the configuration register method for bypassing and resetting lost passwords. Students perform password recovery on Cisco routers and switches in a lab environment.
