Module 1 Summary

Before students move on to Module 2, they must be able to cable the lab setup, identify all external relevant ports, and identify internal router components.

Online assessment options include the end-of-module online quiz in the curriculum and the online Module 1 exam. Consider introducing formative assessments, where the instructor supervises the students as they work on the router setup. The use of formative assessments can be very valuable while students work through this router-intensive and IOS-intensive course.

Students should understand the following main points:

•WAN and LAN concepts

•Role of a router in WANs and LANs

•WAN protocols

•How to configure console connections

•The identification and description of the internal components of a router

•The physical characteristics of a router

•The common ports on a router

•How to connect router console, LAN, and WAN ports
