Huawei HCIE-Datacom study guide
Huawei HCIE-Datacom · Work through your exam, one topic at a time.
HCIE-Datacom is the Expert-level certification in Huawei's Career Certification portfolio, which spans three tiers: Huawei Certified ICT Associate (HCIA), Huawei Certified ICT Professional (HCIP), and Huawei Certified ICT Expert (HCIE). It sits in the Datacom technical field, one of the tracks shown on Huawei's certification roadmap alongside WLAN, Security, Transmission, Access, 5G and LTE. Because it is an HCIE, it is aimed at senior network engineers, solution architects and technical leads who design, deploy and troubleshoot large enterprise or carrier data networks and who want a credential that signals depth rather than breadth. The certification is delivered in two stages: a written exam, supplied by the Pearson VUE testing service company, followed by a separate HCIE Lab Exam that candidates schedule through Huawei's own lab booking process. Huawei's certification procedure lists three steps: schedule an exam, obtain and verify the certificate, and recertify. Note that Huawei provides only e-Certs except for the HCIE, and that certification content is updated and optimized irregularly, with recertification renewing validity and keeping the credential aligned with current ICT developments. Topics on this exam: Datacom. The Huawei HCIE-Datacom study guide has 1 section and about 405 words.
01Datacom
The Datacom domain covers the technologies used in a Huawei data network: routing (OSPF, IS-IS, BGP), MPLS and Segment Routing (SR-MPLS, SRv6), EVPN/VXLAN fabrics, IPv6, multicast, QoS, network security, and automated operations with iMaster NCE, NETCONF/YANG, and telemetry. HCIE-Datacom questions are scenario-heavy: you are given a topology, a business requirement, or a failure symptom and must choose a design, a configuration sequence, or a diagnosis. The lab exam tests whether you can build and repair the same concepts. Fix the underlay first.

- Common mistakesCandidates memorize BGP configuration syntax from written prep and jump straight to overlay protocols, forgetting that BGP sessions depend on IGP reachability to the update-source addresses; the failure looks like a BGP problem but is an underlay problem.
