The passing score for Huawei HCIE-Datacom V1.0 is 600/1000, and the official registration fee is 300 USD. A failed attempt means paying that fee in full again, so your preparation budget deserves the same attention as your study plan.

According to Huawei, candidates should meet the following before registering: It is recommended to pass HCIP-Datacom-Core Technology. 5 years of relevant work experience is suggested.. Requirements can change, so confirm the latest details on the official exam page before you register.
