Huawei HCIA-Transmission V2.0 Exam FAQ: What Candidates Ask Most

What is the Huawei H31-311 exam?

The H31-311 exam is the official Huawei exam behind the HCIA-Transmission certification, validating the skills measured by the Huawei HCIA-Transmission V2.0 credential. It sits at the Associate level of the Huawei certification program. It also connects to HCIP-Transmission, HCIE-Transmission, so the knowledge you build here carries over to those tracks as well.

How many questions are on the H31-311 exam, and how much time do I get?

The H31-311 exam contains 60-70 questions to be completed within 90 minutes. Before exam day, divide the available time by the question count to work out a comfortable per-question pace, and mark any item that eats into it so you can return later instead of getting stuck. Timed sessions in the Getcertkey test engines make that pacing automatic — run at least two full-length mock exams under the clock so time pressure never becomes the reason you drop points.

What score do I need to pass the H31-311 exam, and what does it cost?

The passing score for the H31-311 exam is 600/1000, and the official registration fee is 200 USD. Retakes are not discounted — every new attempt means paying the full fee again — so it pays to measure yourself before you book. Work through the 190 practice questions on Getcertkey, sit a timed practice test, and schedule your exam only when your scores are consistently comfortable. That simple habit is the cheapest exam strategy there is.

Are there any prerequisites for the H31-311 exam?

Official courses build the foundation; the 190 practice questions from Getcertkey then show you how that knowledge is examined, so the two work best together.
