Building A Lab to Pass Cisco Exams
A Cisco Certified Internetwork Expert home lab is certainly a nice way to go, but can be both expensive and challenging to set up. Having said that, a home lab that is well set up using good equipment can help shrink the learning curve and provide excellent hands on experience.
The decision to build your own lab will depend on your budget and your plans for future certifications. The amount of equipment you need to complete your home lab will largely depend on the certifications you are pursuing. Your best bet is to obtain the most general list of major product types to cover a wide range of Cisco certifications.
