What Is the Exam Content of Huawei HCIA Datacom Certification?
Update time：2025-10-10
If you’re stepping into Huawei’s Datacom field, the HCIA-Datacom Certification is your essential first step.
As Huawei’s entry-level networking certification, it’s not too difficult — but to pass efficiently, you first need to understand what’s tested and how to prepare.
This exam focuses on theoretical knowledge and basic operational concepts, without requiring any lab test.
It’s a computer-based exam that includes multiple-choice and true/false questions, lasts 90 minutes, and scores 1000 in total — you’ll need 600 to pass.
Registration is done through the Pearson VUE website under the “Huawei Certification” category, exam code H12-811.
1.Core Exam Content: 5 Major Modules to Build Your Datacom Foundation
The HCIA-Datacom exam focuses on essential networking fundamentals, covering five main modules.
It’s about understanding — not memorizing complex configurations.
(1)Network Fundamentals (25%)
Protocol Models: OSI 7-layer vs TCP/IP 4/5-layer mapping and functions.
IP Addressing: IPv4 classes (A/B/C), subnet masks, and basic subnetting.
Device Roles: Switches (Layer 2), Routers (Layer 3), Gateways (network exit points).
Tip: Questions often focus on IP address ranges and identifying which devices operate at which layer.
(2)Huawei Datacom Products & VRP System (20%)
Device Interfaces: GE ports, Console ports, and Serial interfaces.
VRP Basics: Console/Telnet/SSH login methods, switching between User View and System View, and basic display or save commands.
Dumps focus: command prompts, login types, and configuration save commands.
(3)Routing Fundamentals (20%)
Static Routing: Manual route setup, default routes (0.0.0.0/0).
Dynamic Routing Protocols: RIP vs OSPF — key differences, convergence, and scalability.
Tip: Expect conceptual questions comparing routing methods rather than deep configuration syntax.
(4)Switching Fundamentals (20%)
VLAN: Purpose (broadcast domain separation), port types (Access/Trunk).
STP: Preventing Layer 2 loops.
Eth-Trunk: Link aggregation for higher bandwidth and redundancy.
Dumps highlight: VLAN tagging, trunk encapsulation, STP’s loop-prevention mechanism.
(5)Network Security & Maintenance Basics (15%)
ACL: Filtering specific IP traffic.
SSH: Secure encrypted remote login.
Maintenance Tools: Ping, Traceroute, SNMP — connectivity and monitoring.
2.Efficient Study Strategy (Dumps Driven)
Passing HCIA-Datacom doesn’t require memorization — just understanding key concepts and mastering high-frequency questions.
Step 1: Review the Official Exam Outline
Start by downloading the HCIA-Datacom Exam Guide from Huawei’s website.
Focus only on the listed topics (e.g., IP addressing, VLANs, routing basics).
Skip advanced topics like BGP — they won’t appear in the HCIA exam.
Step 2: Build Knowledge Through Practice
Instead of taking formal training, use real exam dumps to learn and practice:
Step 3: Reinforce with Question Practice & Review
Practice the latest 6–12 month real exam questions.
For wrong answers, revisit related concepts in the official guide — understand why, not just what.
Focus on question clusters like:
“VLAN port type selection”
“Static vs Dynamic routing”
“ACL traffic filtering logic”
Pro Tip: Many successful candidates report that consistent dumps practice boosts accuracy and recall far better than passive video learning.
Common Mistakes to Avoid
Relying solely on rote memorization — HCIA tests understanding.
Ignoring dumps practice — real exam topics repeat with slight variations.
Overpaying for courses — with the right dumps, you can pass efficiently and affordably.
Summary: Build Your Networking Foundation with the Right Tools
The HCIA-Datacom Certification focuses on networking fundamentals — it’s not hard, but requires structured preparation.
Using a comprehensive dumps allows you to master key exam points in 1–2 months of consistent study (1–2 hours per day).
For beginners aiming to enter the networking field or understand Huawei Datacom products, this certification is the best place to start.
