Certification Zone Study Guides by Priscilla Oppenheimer:

Troubleshooting Ethernet

WAN Troubleshooting

Priscilla Oppenheimer has been developing data communications and networking systems since 1980 when she earned her master's degree in information science from the University of Michigan. After many years as a software developer, she became a technical instructor and training developer and taught more than 2000 network engineers from most of the Fortune 500 companies.

Her employment at such companies as Apple Computer, Network Associates, and Cisco Systems gave her a chance to troubleshoot many network design problems and the opportunity to develop practical methods for network design and troubleshooting. Her books "Top-Down Network Design" (Cisco Press, 1999) and "Troubleshooting Campus Networks" (Wiley, 2002) teach those methods.

Priscilla has extensive experience working on Ethernet, Token Ring, FDDI, ATM, Frame Relay, ISDN, AppleTalk, TCP/IP, and Novell NetWare networks. She is a Cisco Certified Design Professional (CCDP), Cisco Certified Network Professional (CCNP), and Certified Network Expert (CNX) in both Ethernet and Token Ring.
