I focus mainly on the art of troubleshooting. " Why troubleshooting?" you may ask.
- Troubleshooting is the highest form of networking skill.
- Inside-out knowledge of the technology is a prerequisite.
- You must be able to "crawl under the skin" of IOS™, and fully comprehend it's strengths and weaknesses.
How do I focus on troubleshooting? I'm running a technical troubleshooting blog and I also coauthored an advance troubleshooting workbook which presents you with such problems that will make you scream in horror, or just challenge your networking skills.
