Huawei H13-821_V3.5 Real Exam Dumps [September 2026 Update]

The cloud-native domain carries approximately 30% of the H13-821_V3.5 exam, and the question type that most consistently separates passing from failing candidates at this level is not “what is a microservice” – every HCIP candidate knows what a microservice is – it is “which specific Huawei Cloud service enables this specific aspect of a microservice architecture?” Candidates who can explain service mesh conceptually but have not mapped the concept to Huawei Cloud Application Service Grid (ASM) will miss the question asking which service provides service-to-service traffic management without requiring code changes in each microservice. Candidates who understand container orchestration but have not specifically studied Cloud Container Engine (CCE) – its node pool configuration, cluster networking model, and integration with other Huawei Cloud services – will miss the questions that present an enterprise containerization scenario and ask which CCE configuration satisfies the described requirements. The cloud-native domain is not asking for definitions. It is asking for the Huawei Cloud implementation of each cloud-native concept, and those are not interchangeable with AWS, Azure, or GCP equivalents. General cloud-native knowledge is necessary but not sufficient.

The Huawei H13-821_V3.5 (HCIP-Cloud Service Solutions Architect V3.5) is the intermediate-level (HCIP – Huawei Certified ICT Professional) certification for architects designing and deploying enterprise cloud solutions on HUAWEI CLOUD. It validates the ability to architect conventional cloud deployments, design cloud-native application systems, plan cloud O&M solutions, and apply Huawei Cloud innovation services to industry requirements. The exam uses multiple formats including single/multiple-choice, true/false, short response, and drag-and-drop questions. Passing score: 600/1000.

Cert Empire’s H13-821_V3.5 exam questions are built at the Huawei-specific service mapping depth the real exam requires – not cloud-native theory, but which HUAWEI CLOUD service implements each architectural capability.

Exam Snapshot

Domain Coverage: Five Knowledge Areas

Domain 1: Cloud Native Application Architecture (~30%)

The cloud-native domain tests Huawei-specific service knowledge at the architectural decision level. Each topic below pairs a cloud-native concept with the specific HUAWEI CLOUD service that implements it.

Cloud Container Engine (CCE) – Kubernetes on HUAWEI CLOUD

CCE provides managed Kubernetes clusters on HUAWEI CLOUD. The exam tests CCE at the configuration decision level: cluster type selection (CCE Standard for general workloads versus CCE Turbo for high-performance, low-latency scenarios using cloud-native networking), node pool design (mixing node types within a cluster for different workload requirements), cluster networking model (VPC networking for CCE, how pods get IP addresses from the VPC CIDR), and how CCE integrates with other HUAWEI CLOUD services such as SFS Turbo for shared storage and SWR for container image management.

A confirmed exam scenario type: an enterprise needs to run multiple application teams in the same Kubernetes cluster while maintaining strict resource isolation and cost attribution between teams. The exam tests whether the correct answer involves namespaces with Resource Quotas (Kubernetes-native isolation), CCE node pools with node affinity (compute isolation), or separate clusters (full isolation at higher cost). Each is technically valid; the exam tests which approach correctly balances the described isolation and cost requirements.

Application Service Grid (ASM) – Service Mesh

ASM is HUAWEI CLOUD’s managed service mesh based on Istio. It enables service-to-service traffic management, observability, and security in microservices architectures without requiring changes to application code – the service mesh operates at the infrastructure layer through sidecar proxies injected alongside each microservice container.

The exam tests what ASM provides that CCE alone does not: fine-grained traffic routing between service versions (enabling canary deployments where a percentage of traffic goes to the new version), mutual TLS (mTLS) authentication between services without application-level changes, circuit breaking (automatically stopping traffic to a failing service to prevent cascade failures), and distributed tracing visualization for debugging latency issues across service boundaries.

The specific exam question pattern: a microservices application has a latency problem that is difficult to trace because requests flow through six services before producing a response. The exam asks which HUAWEI CLOUD service provides the distributed tracing capability to visualize the complete request path and identify which service is adding the most latency. The correct answer is ASM (with its Jaeger/Zipkin integration) rather than AOM, because ASM traces at the service mesh level, not just at the infrastructure metric level.

FunctionGraph – Serverless on HUAWEI CLOUD

FunctionGraph runs functions in response to events without requiring server management. Billing is per-invocation, not per server-hour. The exam tests FunctionGraph’s appropriate use cases and its integration with event sources: DIS (Data Ingestion Service) triggers, OBS (Object Storage Service) triggers (function runs when a file is uploaded), API Gateway triggers (function serves HTTP requests), and timer triggers (function runs on a schedule).

The exam also tests when FunctionGraph is NOT appropriate: functions with very long execution times (FunctionGraph has maximum execution duration limits), workloads requiring persistent connections, GPU-intensive ML inference at high throughput (CCE with GPU nodes is more appropriate), and workloads where cold-start latency is unacceptable in real-time applications.

DevOps Toolchain on HUAWEI CLOUD – CodeArts

CodeArts is HUAWEI CLOUD’s integrated DevOps platform. The exam tests the relationship between CodeArts components: CodeArts Req (agile requirements and task management), CodeArts Repo (Git-based source code repository), CodeArts Build (CI pipeline execution), CodeArts Deploy (CD automation), and CodeArts TestPlan (test case management). The exam presents a CI/CD pipeline requirement – building a containerized application, running tests, pushing to SWR, and deploying to CCE – and tests which CodeArts components handle which stage of the pipeline.

Cloud Native Architecture Migration Strategy

The exam tests the decision framework for how traditional applications are reclassified during cloud-native migration: which application characteristics make an application a good candidate for containerization versus refactoring into microservices versus keeping as a VM-based workload. Characteristics favoring containerization: stateless application logic, multiple language environments, need for rapid scaling, and consistent deployment across environments. Characteristics favoring microservices refactoring: tightly coupled monolith with different scaling needs per module, development teams that could own independent services, and requirements for independent deployment of application components.

Domain 2: Cloud-Based Architecture Design for Conventional Applications (~40%)

Compute Architecture Decisions

ECS instance family selection: The exam tests which ECS instance family is appropriate for which workload profile. Compute-Optimized instances serve high-CPU-ratio needs (batch processing, analytics, gaming servers). Memory-Optimized instances serve high-memory-ratio needs (in-memory databases, large-scale caching). High-Performance Computing instances serve scientific computing, fluid dynamics, and molecular modeling. General-Purpose instances serve web servers, development environments, and mixed workloads.

Auto Scaling policy configuration: The exam tests scaling policy types: metric-based scaling (scale out when CPU exceeds a threshold, scale in when CPU drops below a threshold), scheduled scaling (scale at specific times for predictable load patterns), and manual scaling. The configuration details tested include cooldown periods (time between scaling actions to prevent thrashing), minimum and maximum instance counts, and how lifecycle hooks allow custom actions before instances are fully added or removed from the group.

High availability across Availability Zones: Deploying ECS instances across multiple AZs provides resilience against data center failure. The exam tests how Elastic Load Balance (ELB) distributes traffic across AZ-distributed instances, how the health check configuration determines which instances receive traffic, and how the architecture maintains service continuity when one AZ becomes unavailable.

Network Architecture

VPC design for three-tier applications: The exam consistently tests the three-tier VPC design pattern: web tier in a subnet with EIP or ELB exposure to the internet, application tier in a private subnet accessible only from the web tier, database tier in a separate private subnet accessible only from the application tier. Security Groups enforce these access restrictions. The exam tests Security Group rule design for each tier and why the database tier should never have a direct route to the internet.

Enterprise connectivity patterns: For organizations connecting on-premises infrastructure to HUAWEI CLOUD, the exam tests VPN Gateway (IPsec-encrypted tunnel over the internet, lower cost, higher latency, variable bandwidth) versus Direct Connect (dedicated physical connection, predictable latency, guaranteed bandwidth, higher cost). The selection criteria: latency-sensitive applications (real-time database replication, trading systems) require Direct Connect; less time-sensitive workloads (batch uploads, backups) can use VPN.

Cloud Connect for multi-region architectures: When an organization runs workloads in multiple HUAWEI CLOUD regions and needs private connectivity between them, Cloud Connect provides the HUAWEI CLOUD backbone network connection. The exam tests Cloud Connect as the multi-region equivalent of VPC Peering – VPC Peering is intra-region; Cloud Connect is inter-region.

Storage Architecture

Storage type selection matrix: The exam tests the three-way storage selection decision: OBS for unstructured data accessed via API (images, videos, backups, log archives), EVS for block storage attached to a single ECS instance (database files, OS volumes), and SFS for shared file storage accessible by multiple ECS instances simultaneously (shared code, shared media processing pipelines). The exam presents a workload description and tests which storage type is appropriate – and importantly, which is incorrect and why (attaching EVS to multiple instances simultaneously is not supported in the standard model, for example).

OBS lifecycle and storage tier management: OBS objects can be automatically transitioned between storage tiers based on age: Standard (frequently accessed), Infrequent Access (less frequent), Archive (rarely accessed). Lifecycle rules define when transitions occur and when objects expire. The exam tests how lifecycle rule configuration reduces storage costs for data with predictable access patterns.

Database Architecture

RDS read replica and high availability: The exam tests RDS primary-standby configuration (synchronous replication to a standby for high availability – automatic failover if primary fails) versus read replicas (asynchronous replication to additional instances for read scaling – improves read throughput but introduces replication lag). When a scenario describes a read-heavy database workload with acceptable read latency, the correct answer involves read replicas; when it describes mission-critical transaction data with zero-downtime requirements, primary-standby configuration is required.

DCS (Distributed Cache Service) integration patterns: DCS provides managed Redis and Memcached. The exam tests how DCS is positioned in front of RDS for read-heavy workloads: the application queries DCS first; if the data is not found (cache miss), the application queries RDS and writes the result to DCS for subsequent requests. The exam tests cache invalidation strategy and when cache-aside versus write-through patterns are appropriate.

Domain 3: Huawei Cloud O&M Solution (~15%)

Cloud Eye (CES) alarm configuration: Cloud Eye monitors resource metrics (CPU, memory, disk, network) and fires alarms when metrics breach configured thresholds. The exam tests alarm configuration: selecting the correct metric, setting threshold values, configuring the evaluation period (how many consecutive data points must breach the threshold before the alarm fires), and selecting the notification channel (SMN topic for email/SMS, or triggering an Auto Scaling action).

Application Operations Management (AOM): AOM provides application-layer monitoring: tracing application performance across service calls, collecting application logs, and providing a unified view of application health. The exam tests how AOM complements Cloud Eye – Cloud Eye sees infrastructure metrics, AOM sees application-level behavior.

Log Tank Service (LTS) for centralized logging: LTS ingests logs from ECS instances, CCE pods, and cloud services, enabling centralized log search and analysis. The exam tests LTS as the destination for structured application logging and how log groups and log streams organize log data from different sources.

Domain 4: Huawei Cloud Innovations and Solutions (~10%)

AI and ModelArts: ModelArts is HUAWEI CLOUD’s end-to-end AI development platform covering data labeling, model training, model optimization (for deployment on edge and cloud), and model deployment as inference services. The exam tests ModelArts’s position in the AI lifecycle – it is the platform that spans from data to deployed model, not just a training environment.

Industry solutions awareness: HUAWEI CLOUD offers pre-packaged solutions for specific industries: finance (compliance-hardened environments meeting financial regulatory requirements), healthcare (HIPAA-aligned architectures for medical data), manufacturing (industrial IoT integration with OT/IT convergence), and smart city (IoT data aggregation and analytics). The exam tests these at the awareness level – which solution addresses which industry challenge – rather than deep configuration.

5 Study Tips for Huawei H13-821_V3.5

• Tip 1: For every cloud-native concept you study (service mesh, serverless, container orchestration, CI/CD), explicitly map it to the specific HUAWEI CLOUD service name. Knowing “service mesh” is insufficient – the exam expects “ASM” and tests its specific capabilities, not just the concept.
• Tip 2: Practice the conventional architecture domain by working through three-tier application scenarios: web tier, application tier, database tier, with specific HUAWEI CLOUD services named at each layer and Security Group rules described explicitly.
• Tip 3: Study Auto Scaling policy types – metric-based, scheduled, and manual – and the specific configuration decisions within each: cooldown periods, capacity limits, and how policies interact with ELB health checks.
• Tip 4: Know the RDS primary-standby versus read replica distinction clearly. The exam frequently presents a database workload description and asks which configuration is appropriate – the answer depends on whether the requirement is high availability (primary-standby) or read scaling (read replicas).
• Tip 5: Practice with Cert Empire’s H13-821_V3.5 exam questions built at the HUAWEI CLOUD service mapping depth – scenario questions that name a business requirement and test which specific Huawei Cloud service combination addresses it.

Readiness Check

1. A financial services company is migrating a monolithic payment processing application to HUAWEI CLOUD. The application consists of a transaction processing engine (CPU-intensive, scales independently), a customer notification service (lightweight, event-driven), and a reporting module (memory-intensive, runs on a fixed schedule). Describe which HUAWEI CLOUD compute service is most appropriate for each component – distinguishing between CCE, FunctionGraph, and ECS with appropriate instance family – and explain the architectural reason for each choice.
2. An e-commerce platform running 12 microservices on CCE is experiencing intermittent latency spikes, and the operations team cannot determine which service is responsible because requests flow through multiple services before completing. Identify which HUAWEI CLOUD service provides the distributed tracing capability needed to visualize the full request path across all 12 microservices, explain why this service can trace inter-service calls without requiring code instrumentation in each microservice, and name the underlying mechanism that makes code-transparent tracing possible.
3. A manufacturing enterprise has on-premises ERP data that must be synchronized in real time to a HUAWEI CLOUD RDS database for a cloud-based analytics platform. The synchronization has a strict maximum 50ms latency requirement. Evaluate the two connectivity options available (VPN Gateway and Direct Connect) against this requirement and identify which is appropriate, explaining what characteristic of each option makes one unsuitable for this latency requirement.
4. An enterprise runs a content delivery application where 90% of requests read the same product catalog data and 10% involve write operations. The RDS database is under high read load causing query latency. Describe the architecture change using HUAWEI CLOUD services that addresses the read load problem, explain how the application’s request handling would change with this architecture, and identify the key trade-off introduced by this approach.
5. A cloud architect is designing a multi-service application on HUAWEI CLOUD where the web tier handles user-facing HTTP requests, the application tier processes business logic, and the database tier stores transaction records. All three tiers are deployed in the same VPC. Describe the Security Group configuration required to ensure that the database tier is accessible only from the application tier and not directly from the web tier or the internet, naming the specific Security Group rule parameters involved.
