The whole Cisco courses, blog spam, SEO industry are some of the worst things to exist in technology. I hope all of them gets burned by a massive fire. Who even thinks of becoming a SEO consultant?
These Cisco certifications are such a scam tbh. Cisco commands and CLI are the most confusing, illogical designs for any feature. And they make sure to put in tens of thousands of features and hundreds of ways to configure every different feature. Then they create these overpriced courses and pay for their own employees to take every single one. Since Cisco employs a lot of people, and prefers people with Cisco certifications, this creates a lot of demand for the courses.
Most of the certifications could be replaced with a single 2 month networking course that explains the workings of features, provided they redesign their CLI to be slightly usable.
