The Datacom track in the Huawei certification exam mainly examines network knowledge related to data communication, including but not limited to network design, network architecture, network protocols, network security, and network optimization. The following are some of the knowledge points that may be examined in the direction of data communication in the Huawei certification exam:
1.Network Design: Examine the knowledge of network topology, IP address planning, routing protocol selection, VPN architecture design, etc., to evaluate candidates' understanding and practical ability of network design.
2.Network Architecture: It mainly examines candidates' understanding and practical ability of network architecture, including enterprise network architecture, campus network architecture, data center architecture, etc.
3.Network Protocol: It mainly examines the knowledge of TCP IP protocol family, various routing protocols (such as OSPF, BGP, IGP, etc.), switching protocols (such as STP, RSTP, etc.), application layer protocols (such as HTTP, FTP, SMTP, etc.), etc., in order to evaluate candidates' understanding and practical ability of network protocols.
4.Cybersecurity: It mainly examines the concepts and protective measures of network security, including the knowledge of firewalls, intrusion detection systems, security audits, etc., in order to assess the candidates' understanding and practical ability of network security.
5.Network Optimization: This course mainly examines network optimization techniques, including QoS technology, traffic control, link aggregation, redundant backup, etc., to evaluate candidates' understanding and practical ability of network optimization.
In addition, the Huawei certification exam may also examine other technologies related to data communication, such as emerging technologies such as the Internet of Things, cloud computing, and big data, as well as Huawei's unique network products and technologies, such as Huawei Cloud, Huawei switches, and Huawei routers.
In short, the test content of the Huawei certification exam is very extensive, and candidates need to have solid basic network knowledge, practical experience, and good overall quality.
