Certification Zone Study Guides by Chuck Larrieu:

3550 Switch

Chuck Larrieu learned networking as the logical outgrowth of doing technical support at Merrill Lynch's San Francisco Institutional Sales Office, and later as Technology Manager for Van Kasper & Company (now a part of Wells Fargo Investments), at the time a regional brokerage firm headquartered in San Francisco. It was there that he discovered Cisco routers and switches, and realized that the future of technology lay in connecting people, systems, and businesses. He now works as a Design Engineer for SBC DataComm, a premier network integrator and Cisco Gold Partner. His role is to provide advice and network designs for complex projects. Chuck currently has no life, as he continues to prepare for his CCIE Lab.
