I received my first Cisco cert six years ago, and have been working in the industry since then. One thing I learned quickly is that while you'll learn plenty from all the tests, some implementations don't actually work great in the real world. One day I would love to see a Cisco Best Practices Course for Real World designs. Just a thought,
Recommended Course / Cisco Best Practices
There aren't enough days to do this.🤣 The issue is more about application. Everyone has an application that doesn't fit neatly. This is why there are Design Engineers and Implementation Engineers you call as consultants for Cisco. They also have on their site CVD pdf (Cisco Validated Design?) which means this is how it is supposed to be done.
Their design level certification is there to help you to know those best practices; the implementation engineer tells you it can be done with what technologies, configurations and maybe actual physical installation of equipment and management of configuration. Sometimes, the implementation engineer has to say there isn't a Cisco Product (gasp!) that fits that bill.
So, as always, you can submit that as a course request through the chat bubble on the site. That will insure that your request has been officially logged and will get to the right people as it comes time for those decisions!
