There is a new Huawei website that describes clearly Huawei certification track. Maybe some of you have already found it. For those, who are still looking for such information I am giving a direct link to official Huawei certification track.
I think this is useful news for those, who are interested in passing Huawei certification exams. It was not easy to find such information a few months ago.
It seems that Huawei started to treat its certification seriously.
