What Does the Huawei Certification Data Communication Exam Cover?
Update time：2025-03-17
Huawei certification is highly influential in the ICT field, and its data communication (Datacom) exams cover a broad and detailed range of topics. These exams play a crucial role in training and selecting skilled professionals for the industry. Below, I will provide a detailed breakdown of what is covered in the Huawei certification Datacom exams.
Huawei’s Datacom exams focus on different aspects depending on the certification level. However, all levels revolve around key areas such as fundamental networking knowledge, Huawei network device operation and configuration, network architecture planning and design, and network troubleshooting.
HCIA Datacom: Foundational Level
As the entry-level certification in the Huawei certification system, the HCIA Datacom exam primarily tests candidates on basic networking knowledge. This includes fundamental networking concepts such as IP address classification and subnet mask calculations—just like defining land boundaries before constructing a building, these are essential foundations for building a network.
Additionally, the exam covers the OSI seven-layer model and the TCP/IP protocol stack. Understanding these is similar to knowing the roles of different workers in a large-scale project—each layer has its specific function and responsibility. The exam also includes basic Huawei networking device operations, such as logging into devices and executing simple command-line operations, allowing candidates to gain initial hands-on experience with Huawei equipment.

HCIP Datacom: Intermediate Level
At the HCIP level, the difficulty increases significantly. The exam content focuses more on in-depth understanding and comprehensive application of networking technologies.
For example, in routing and switching technologies, candidates need to master multiple dynamic routing protocols such as OSPF and IS-IS, understanding their working principles, advantages, disadvantages, and how they apply to different network scenarios. This is similar to planning different transportation routes based on cargo type, destination, and other factors to choose the most efficient path.
In campus network planning and deployment, candidates must consider network topology design, IP address planning, VLAN segmentation, and more. Building an efficient, stable, and easily managed campus network is a key focus of the exam.
The exam also covers WAN technologies, including Frame Relay, PPP, and other protocols used to connect networks across different geographical locations. These technologies function like highways connecting different cities, ensuring smooth long-distance data transmission.
HCIE Datacom: Expert Level
The HCIE Datacom exam represents the highest level of Huawei Datacom certification. Beyond a deeper and more comprehensive assessment of the topics covered in previous levels, this exam places a strong emphasis on practical skills and innovative thinking.
In complex network architecture design, candidates must design high-reliability, high-performance, secure, and scalable network architectures based on business needs and future development plans of enterprises. This requires a deep and integrated understanding of various network technologies.
Network troubleshooting is another critical part of the HCIE exam. Candidates must demonstrate their ability to quickly identify and resolve issues in simulated complex network environments. This not only tests their technical expertise but also challenges their emergency response skills and problem-solving abilities.
Achieving HCIE-level certification signifies that a candidate possesses the ability to lead the planning, implementation, and maintenance of large-scale,
complex network projects.
Conclusion
Huawei’s Datacom exams, from basic to advanced levels, systematically evaluate candidates’ knowledge and skills in networking. They help supply the ICT industry with top-tier professionals and drive the industry’s continuous development. Whether you are a newcomer looking to enter the networking field or a professional seeking career advancement, obtaining Huawei Datacom certification is an excellent way to enhance your skills and showcase your expertise.
