Course Outline:

Lesson 1: Comparing OSI Model Network Functions

Computer networks are complex systems that incorporate multiple functions, standards, and proprietary technologies. The Open Systems Interconnection (OSI) model is used to try to simplify some of this complexity. It divides network technologies between seven functional layers. This makes it easier to separate and focus on individual concepts and technologies while retaining an understanding of relationships to the functions of technologies placed in other layers.

This lesson uses the OSI model to give you an overview of the technologies that you will be studying in the rest of the course. You will compare the functions of these layers in the OSI model and apply those concepts to the installation and configuration of a small office/home office networl.

Lesson 2: Deploying Ethernet Cabling

In this topic, you will summarize standards for deploying Ethernet over copper and fiber optic media types and identify the tools and techniques required to deploy Ethernet cabling.

Lesson 3: Deploying Ethernet Switching

Cabling establishes the links between nodes on the network, but each node also requires a network interface. Not many networks are established by directly connecting each end system to every other local system. Cabling and support costs are reduced by using intermediate systems to establish local networks. These intermediate systems are deployed as network appliances such as hubs, bridges, and switches. Installing and configuring, these devices will be a regular task for you during your career in network administration.

Lesson 4: Troubleshooting Ethernet Networks

In this lesson you will explain the steps in CompTIA’s Network+ troubleshooting methodology and apply these steps to solving common cable and connectivity issues.

Lesson 5: Explaining IPv4 Addressing

In this lesson, you will identify the addressing and data delivery methods of the Internet Protocol (IP). IP is at the heart of most modern networks, and consequently one of the most important topic areas for a network professional to understand and apply.

Lesson 6: Supporting IPv4 and IPv6 Networks

This lesson also introduces IPv6 addressing concepts and highlights some key differences between IPv6 and IPv4.

Lesson 7: Configuring and Troubleshooting Routers

Routers work at layer 3 to aggregate information about neighboring networks and forward packets along an appropriate path to their final destination. While configuring routing infrastructure is often a senior job role, you should understand basic concepts and be able to apply them to solve common issues.

Lesson 8: Explaining Network Topologies and Types

The cabling, switching, and routing functions of the first three layers in the OSI model can be deployed in many ways to implement networks of varying sizes and with different purposes. Being able to summarize these network types and topologies and the different network appliance models that support them will help you to build networks that meet customer goals for performance and security.

Lesson 9: Explaining Transport Layer Protocols

Layers 1 through 3 of the OSI model are concerned with addressing and packet forwarding and delivery. This basic connectivity is established for the purpose of transporting application data. In this lesson, you will learn to describe how protocols at layer 4 provision the transport services that network applications depend upon.

Lesson 10: Explaining Network Services

This lesson focuses on application protocols that perform low-level network operations tasks, such as providing dynamic address or name resolution services. You should understand the functions of the network services protocols and the ports that they rely upon to operate.

Lesson 11: Explaining Network Applications

Where DHCP and DNS support basic network operations, other application protocols provide platforms for user-level services, such as websites, databases, file/printer sharing, email, and voice/video calling. You must be able to identify the ports used by these services and their performance and security requirements so that you can assist with product deployments and upgrades and perform basic troubleshooting.

Lesson 12: Ensuring Network Availability

In this lesson, you will investigate some tools and management methods that will help you determine your network’s baseline and optimize your network’s performance.

Lesson 13: Explaining Common Security Concepts

In this lesson, you will describe basic concepts related to network security. As a networking professional, it is part of your responsibility to understand these fundamental concepts so that you can support network security controls.

Lesson 14: Supporting and Troubleshooting Secure Networks

Each day, the number and complexity of threats against systems integrity and data security increases. In response, there are more and more security controls available to automate the detection and prevention of these threats. Because you are a networking professional, your organization and users will be looking to you to deploy these security appliances, without compromising network availability and performance.

Lesson 15: Deploying and Troubleshooting Wireless Networks

Unbounded or wireless media technologies have distinct advantages for businesses over bounded media. They can be easier to install to existing premises and they support the device mobility that users require from laptop or smartphone-based access to networks. Wireless technology implementations offer various advantages, but you need to understand their limitations and security issues to support them properly in your network environments.

Lesson 16: Comparing WAN Links and Remote Access Methods

In this lesson, you will identify the characteristics of WAN service provider offers and components of remote access network implementations.

Lesson 17: Explaining Organizational and Physical Security Concepts

Managing a site so that the network is highly available and secure involves creating policies and best practices, supported by documentation. This might seem less immediately rewarding than getting a new application or server up-and-running, but these kinds of operational procedures are just as important to well-managed networks.

Lesson 18: Explaining Disaster Recovery and High Availability Concepts

Even with effective management procedures and premises security controls, disasters can overwhelm a site and threaten the core functions that a business must perform. Planning for disasters and designing systems for high availability is critical to supporting these mission essential functions. As an entry-level technician or administrator, you should be able to explain the importance of these concepts and identify the tools and techniques used to implement them.

Lesson 19: Applying Network Hardening Techniques

There are many ways in which networks can be attacked and just as many ways for making networks more secure. You will need a basic understanding of the security risks, and security methods and tools, in order to protect your network. In this lesson, you will learn to compare and contrast common types of attacks and to apply network hardening techniques.

Lesson 20: Summarizing Cloud and Datacenter Architecture

This lesson completes the Network+ course by summarizing the software-driven virtualization, automation, and orchestration functionality that underpins cloud services.
