1) HCIA- data communication technology: data communication is an important part of network infrastructure and one of the key technologies to build a network. Therefore, HCIE authentication in data communication direction is a hot direction among all HCIE authentication. HCIE certification of data communication direction proves personal professional skills in network architecture design, network operation and maintenance, troubleshooting and so on. For people engaged in network architecture design, network operation and maintenance, network security and other work. HCIE authentication is very valuable in the direction of data communication. In addition, due to the rapid development of network technology, HCIE authentication in data communication direction is also an authentication direction that needs continuous learning.

3) HCIA- Storage Technology: This subject mainly covers the basic knowledge of storage systems, the application and configuration of storage devices, storage networks and protocols, storage performance optimization, storage security and management. Candidates need to master the knowledge of storage system architecture, common failures of storage devices and their handling methods, basic protocols and applications of storage networks.
4) HCIA- Cloud Computing Technology: This subject mainly covers the basic knowledge of cloud computing, cloud computing platform and application, cloud computing security, cloud computing management and operation and maintenance. Among them, candidates need to be familiar with various service modes, key technologies, security and management of cloud computing.
5) HCIA- Artificial Intelligence Technology: This subject mainly covers the basic knowledge of artificial intelligence, machine learning, deep learning, natural language processing, computer vision, artificial intelligence application, artificial intelligence security and so on. Candidates need to understand the basic concepts, algorithms, application scenarios and cases of artificial intelligence, as well as the security and risks of artificial intelligence.
6) HCIA- Security Technology: This subject mainly covers the basic knowledge of network security, security equipment and technology, security management and operation, application security and so on. It focuses on network attack and defense technology, intrusion detection and defense, data encryption and decryption, security strategy and risk assessment.
The above are the main subjects of HCIA certification examination. Candidates need to pay attention to the knowledge points and difficulties of these subjects in the preparation process, arrange the preparation time and methods reasonably according to their own reality and learning ability, get good grades and pass the certification examination.
With the continuous development of science and technology, the upgrading speed of information technology is getting faster and faster, and the IT industry is getting more and more attention. Therefore, passing the IT certification exam can prove that you have a certain level of skills and knowledge, which will help improve your professional competitiveness.
Huawei certification examination is one of the well-known IT certification examinations in China, with strict certification standards, high test difficulty, wide coverage and great difficulty in preparing for exams. However, as long as you prepare carefully and master the key points and difficulties of the exam, I believe anyone can pass the HCIA exam.
In the preparation process, candidates can obtain related learning resources such as teaching materials and videos through official website or training institutions. At the same time, you can also take online or offline mock exams and get familiar with the exam forms and questions. Candidates can also combine their own reality to deepen their understanding and mastery of exam knowledge.
On the day of the exam, candidates need to abide by the rules of the examination room, carefully examine the questions, carefully answer the questions, and pay attention to time management to ensure that the exam is completed within the specified time. If the examinee finds that he has encountered a difficult problem, he can skip it first, finish other questions first, and then come back and think carefully.
In addition, in the process of studying the HCIA certification exam, candidates can refer to the following suggestions:
1. Systematic learning materials: each subject of HCIA certification examination has corresponding teaching materials. Candidates can systematically learn relevant knowledge points and establish a complete knowledge system by purchasing textbooks or attending training courses.
2. Skill operation: theoretical study is only the first step, and candidates need to consolidate knowledge points in actual operation. We can strengthen our skill operation ability by setting up experimental environment and simulation scenarios.
3. Practice more questions: Practice questions are an effective way to test your mastery. Candidates can test their learning effect by doing real questions or practicing question banks, and find and make up for their shortcomings in time.
4. Exchange learning: Joining the HCIA certification learning exchange group or forum can exchange learning experience with other candidates, solve problems together, and get some practical preparation suggestions and test experience.
5. Continuous learning: The subject content of HCIA certification examination is a relatively new technical field. Candidates need to constantly learn and update their knowledge and keep pace with the times in order to better adapt to the new working environment and business needs.
In the learning process, candidates need to pay attention to the combination of theory and skills, practice more and think more, and gradually establish their own learning system and way of thinking, so as to better prepare for the HCIA certification exam.
