Chapter 2: Best Practices
The instructor should:
 Make this chapter as hands on as possible.
 Encourage students to do the chapter activities and labs.
 Invite speakers to the classroom from local service providers.
 Schedule a field trip to a business that supports remote networked
offices.
 Explore prices for leased lines on the Internet.
 Use the SPAN Engineering model and assign a group project for
students to create their company which needs to be networked; for
example, Auto Parts Store, Clothing Designer, and so on.
 Assign students to interview employees that work at service
providers to discuss daily duties.
 Assign students reports covering one of the different WAN
Infrastructures and give an oral presentation to the class.
