Description
This is the last course in a five-part series on Cisco Internetwork Troubleshooting 4.0 (CIT 4.0). CIT 4.0 teaches students how to baseline and troubleshoot an environment using Cisco routers and switches for multiprotocol client hosts and servers. This is an advanced series that shows networking professionals troubleshooting processes on Cisco Routers and Catalyst Switches. This course will cover Frame Relay WANs and ISDN BRI.
Audience
This series is aimed at network systems analysts and maintenance personnel responsible for troubleshooting network problems. This course will help candidates prepare for the Cisco Certified Network Professional (CCNP) exam 640-506.
