Good training institutions, don't watch advertisements, this authorization and that, VMware doesn't have many authorizations at all, just report to the original VMware training. Don't listen to the so-called authorized training institutions outside. VMware has a training department, you can ask them specifically. I did the same thing last time. Many organizations say that they have authorization, and only the original factory knows best, so ask the original factory directly. At that time, the original factory said that only six companies in China had the authorization to do original factory training: Shenma, Jiajie, Futong, ingram micro, Hangzhou Wit Education and Qunhuan. Only these six, the others are gone. The original factory training is given by the original factory lecturer, the experiment is also provided by the original factory, and there is Chinese food, which is much more detailed and much better than the external lecturer. This is my personal suggestion. There is no discount for signing contracts with the original factory and several big companies. You can try Hangzhou Weite Education. I signed up with them last time. Classes are offered by the original factory, and there are often classes in Shenzhen and Guangzhou!
