Urgent: Excuse me, which communication engineering major is suitable for the intermediate level of "Huawei, Cisco, Soft Test Network Engineer"?

In fact, all your lists are the same, there is not much difference, because they are all the same. However, if you have no plans to go abroad for development in the future, I suggest you take the Huawei exam, because Huawei's products have been recognized by the world now, and most domestic enterprises are Huawei products. After all, it is more cost-effective than Cisco. Of course, in the end, it depends on your personal wishes.
