Description

Packet Tracer - WAN Concepts Objectives In this activity, you will investigate various types of WANs by exploring a topology that uses diverse connectivity technologies. 

Describe different WAN connectivity options.

Background / Scenario You will explore WAN technologies that are used to connect business and home users to data services. Note: There is no scoring in this activity.

Instructions Part 1: Investigate Consumer WAN Technologies for Home and Mobile Devices. Step 1: Explore Consumer WAN Technologies. In this step, you will explore three consumer WAN technologies and home networks. a. Look at the two home networks. Question:

What are the WAN technologies in use?

Examine the connections used in the network topology by selecting the Connections icon (the orange lightning bolt) in the PT devices menu. Hover over the media icons to display their names in the white box at the bottom of the PT window. Question:

What media is used to connect the two home networks to the ISP? What devices in the home networks are directly connected to the ISP?
