HCIP-Datacom-Core Technology V1.0 (H12-821) is a professional-level Huawei certification exam. The blueprint splits the exam across 6 domains, starting with Advanced Routing, Advanced Switching, Network Design. On exam day you face around 60 questions in 90 minutes, in formats such as multiple-choice. The 5 questions below are free samples written to match that style: answer each one first, then reveal the correct answer and note which topics you miss. The H12-821 is rated hard in difficulty, and most candidates prepare with at least 12 months of hands-on experience. Because every answer is revealed in place, you can work through the whole set without leaving this page. Work through all 5 samples before deciding whether to buy the full 28+ question PDF.
