CCNP 4 Network Troubleshooting Lab Companion

This is the first edition of the Network Troubleshooting Lab Companion for students in the CCNP 4 Network Troubleshooting Cisco Networking Academy Program course. The book is specifically designed to supplement the CCNP 4 online course version 3.0 and to prepare students for the updated CIT exam. This lab manual provides detailed practice scenarios with troubleshooting basics to complex issues associated with LANs and WANs built with Cisco devices. Topics include documentation, baselining, troubleshooting tools, troubleshooting methodologies, and per-OSI-layer troubleshooting techniques. This title, combined with the Cisco Networking Academy Program CCNP 4: Network Troubleshooting Companion Guide helps prepare students for the Cisco Internet Troubleshooting Support (CIT) exam. CIT is a qualifying exam for the CCNP certification. The CIT exam certifies that the successful candidate has important knowledge and skills necessary to troubleshoot sub-optimal performance in a converged network environment. The exam covers topics on establishing a baseline, determining an effective troubleshooting strategy, resolving problems at the physical and data link layers, resolving problems at the network layer, and resolving problems at the transport and application layers.
