Many people ask: “What exactly is tested in the HCIE-openEuler exam? How much prior knowledge do I need?”
As someone who has worked with multiple Euler certifications, I’ll explain the core content and key preparation points of this top-level certification in plain language.
First, What Is HCIE-openEuler?
HCIE-openEuler is the expert-level certificate in Huawei’s Euler certification system (under the operating system track). It is designed for senior professionals such as technical leaders or system architects who can design enterprise-level Euler architectures and solve complex issues.
Note: This exam is not for complete beginners. Typically, candidates need at least 3+ years of Linux/Euler experience, and it’s highly recommended to first pass HCIP-openEuler to build the foundation.
1. What Does HCIE-openEuler Test?
The exam has two parts: Written + Lab. Both are essential.
(1) Written Exam
Duration: 90 minutes
Passing Score: 600 / 1000
The written test focuses on advanced technical theory (not basic commands). Core areas include:
Cloud-Native Integration: Deploying and managing Kubernetes clusters on Euler OS, containerized applications, and adaptation to Euler.
Cloud Storage Integration: Connecting Euler OS with Huawei Cloud storage (object, block), plus backup and recovery design.
Intelligent Monitoring & Logging: Using tools (e.g., Prometheus, ELK) for system-wide monitoring and log-based fault analysis.
Key tip: Don’t just memorize steps — you must understand why configurations are needed (e.g., why K8s requires special settings on Euler).
(2) Lab Exam
Duration: 8 hours (480 minutes)
Format: Hands-on operations on real devices
This is the toughest part. Candidates face enterprise-like extreme scenarios and must:
Design a high-availability architecture (disaster recovery, resource scheduling, redundancy).
Handle complex failures (e.g., large-scale node crashes, data corruption) and restore services quickly.
Submit design documentation explaining architecture logic and troubleshooting steps.
Unlike the written test, there’s no single “correct answer.”What matters is whether your solution keeps services running and is technically sound.
2. Key Preparation Advice (Avoid These Pitfalls)
Preparing for HCIE-openEuler usually takes at least 6 months. Reading books alone won’t be enough. Focus on three areas:
Strengthen your foundation
Linux knowledge and HCIP-openEuler are prerequisites. Without them, advanced HCIE topics (like clustering and storage) will be very difficult.
Practice on real equipment — not just simulators
The lab exam simulates complex failures that cannot be replicated on simple emulators.
Follow the latest official exam outline
Huawei updates the syllabus regularly (for example, cloud-native features were added in 2024). Always check the latest official exam guide before studying, to avoid wasting time on outdated topics.
Final Words
The HCIE-openEuler is highly valuable (often required for senior operations and architecture positions in top companies), but it’s also very challenging. Success depends not only on theoretical knowledge, but also on the ability to design solutions and resolve extreme real-world problems.
To prepare effectively, use an updated HCIE-openEuler dumps with practice exams and lab cases. This helps you identify gaps, simulate exam conditions, and build the confidence to succeed.
At the end of the day, enterprises aren’t looking for candidates who only hold a certificate — they want experts who can solve problems under pressure. With the right preparation and practice, HCIE-openEuler can become your strongest career credential.
