I would like to know where I can study troubleshooting for cisco routers and switches.
Can someone guide me on this?
For CCNP TS course and exam, there is a book from Cisco press
For practice TS at CCNA level, u can get PT and some labs for it. I have seen lot of free labs with issues posted on CLN, check https://learningnetwork.cisco.com/groups/ccna-study-group
