To fully practice some of the exam objectives, you need to create a network with two (or more) routers networked together with one (or more) Cisco switches. We recognize that finances may be limited, and suggest purchasing routers from the Cisco 2500 series (primarily the 2501 or 2514 routers). These can commonly be found for between $50.00-$150.00 through a used equipment vendor or online auction. Likewise, a Catalyst 1912 or 1924 switch can typically be found for under $50.00. Some of the syntax on the 1900 series switches may be slightly dif- ferent than Cisco's mainline switches, but most of the commands will be similar. Do realize that Cisco has strict restrictions about using used or remanufactured equipment in production networks. Although Cisco hardware can be resold, the software that runs them (Cisco's IOS) cannot. Before used or remanufactured equipment can be used in a production environment, the IOS software must be re-licensed through Cisco or an authorized reseller. Be sure to ver- ify these regulations before using your lab equipment in a production network.

Hardware as a service

While it's common for individuals or businesses to purchase computer hardware and then periodically replace or upgrade it, there's also the possibility to lease physical and virtual hardware from a service provider. The provider then becomes responsible for keeping hardware up to date, both in terms of its various components and the software running on it.

In the HaaS model, physical components that belongs to a managed service provider (MSP) is installed at a customer's site and a service-level agreement (SLA) defines the responsibilities of both parties. Sometimes, the client pays a monthly fee for using the hardware; sometimes, its use is incorporated into the MSP's fee structure for installing, monitoring and maintaining the hardware. Either way, if the hardware breaks down or becomes outdated, the MSP is responsible for decommissioning it and replacing it. Depending upon the terms of the SLA, decommissioning may include wiping proprietary data, physically destroying hard drives and certifying that old equipment has been recycled legally.
