Huawei H13-811_V3.5 Real Exam Dumps [September 2026 Update]

A confirmed H13-811 exam question presents four statements about the Scalable File Service (SFS) and asks which is incorrect. One of the four options reads: “SFS cannot be used independently. It must be attached to an ECS.” This statement is false – and the exam tests that candidates know it is false. SFS is a shared network file system that multiple ECS instances can mount simultaneously, but it is not required to be attached to any single ECS to exist or function. This distinction matters because EVS (Elastic Volume Service) operates differently: EVS volumes are block storage that attach to a single ECS, and that attachment is what makes them usable. The two services are commonly studied together under storage, which creates a transfer error – candidates who have just read about EVS’s attachment model apply it incorrectly to SFS. The false statement about SFS exists precisely because this error is predictable, and the exam uses it to find candidates who have learned the storage services as a list of properties rather than as distinct technical architectures. Knowing that SFS supports shared access from multiple ECS instances simultaneously, uses NFS protocol, and does not require attachment to any individual ECS is what distinguishes a passing answer on this confirmed question type.

Exam Snapshot

Domain Weights

Domain 1: Cloud Basics (15%)

Service delivery models: IaaS provides virtualized compute, network, and storage – the customer manages operating systems, middleware, and applications. PaaS provides a managed runtime environment – the customer manages applications and data. SaaS provides complete applications – the customer manages only user configuration. The exam tests which model applies to which described scenario and where the management boundary lies for the customer versus the provider.

Cloud deployment models: Public cloud (shared infrastructure, multi-tenant, HUAWEI CLOUD manages everything), Private cloud (dedicated infrastructure for a single organization), Hybrid cloud (combination of public and private with data and workload portability between them). The exam tests selection criteria: regulatory compliance requirements that mandate data sovereignty drive private or hybrid; cost optimization and elasticity drive public.

HUAWEI CLOUD infrastructure: Regions are independent geographic clusters of data centers. Availability Zones (AZs) are independent power and network within a region – deploying across multiple AZs provides resilience against a single AZ failure. Enterprise Projects are organizational groupings for resource management, access control, and billing allocation within an account. The exam tests the relationship between these infrastructure concepts and when each matters for architecture decisions.

HUAWEI CLOUD global market position: The exam tests awareness of HUAWEI CLOUD’s position as a major global cloud provider, its certification ecosystem (HCIA → HCIP → HCIE), and the types of services it provides across IaaS, PaaS, and SaaS delivery models.

Domain 2: Compute Cloud Services (20%)

Elastic Cloud Server (ECS)

ECS instance families: The exam tests which instance type is appropriate for which workload:

• General-Purpose: balanced CPU-to-memory ratio for web servers, development environments, and mixed workloads.
• Compute-Optimized: high CPU ratio for batch processing, high-performance web servers, and analytics.
• Memory-Optimized: high memory ratio for in-memory databases, large-scale caching, and big data analytics.
• GPU-Accelerated: for AI/ML training and inference, rendering, and scientific simulation.
• High-Performance Computing (HPC): for scientific computing, gene sequencing, and fluid dynamics simulation.

Bare Metal Server (BMS): Dedicated physical servers with no hypervisor layer – no virtualization overhead, no performance sharing. Applicable to high-performance computing scenarios (supercomputing, gene sequencing, AI training at scale), regulatory requirements for dedicated hardware, and workloads where virtualization overhead is unacceptable. BMS also supports VPC and Security Group isolation and integrates with HUAWEI CLOUD’s security components. The exam tests which scenarios are appropriate for BMS versus ECS.

ECS billing modes: The exam tests three billing modes: Annual/Monthly (commit to a term for a discounted rate), On-Demand (pay by the hour with no commitment), and Competitive Bidding/Spot (use spare capacity at reduced prices with possible interruption). The exam tests which billing mode is most cost-effective for which usage pattern: stable long-running workloads use Annual/Monthly; variable or unpredictable workloads use On-Demand; fault-tolerant batch workloads can use Spot pricing.

Image Management Service (IMS): IMS manages operating system images used to provision ECS instances. Public images are HUAWEI CLOUD-provided OS images. Private images are customer-created from existing ECS instances (capturing current configuration for standardized deployments) or uploaded from external sources. Marketplace images are pre-configured application environments. The exam tests the three image types and their creation processes.

Auto Scaling: Auto Scaling automatically adjusts the number of ECS instances in a scaling group based on defined policies. Scaling policies: metric-based (scale when CPU exceeds 80%; scale in when CPU falls below 20%), scheduled (scale up at 8 AM on weekdays; scale down at 8 PM), and manual. The exam tests cooling periods (minimum time between scaling actions to prevent thrashing), minimum and maximum instance count bounds, and how Auto Scaling integrates with ELB to update the load balancer’s backend pool when instances are added or removed.

Cloud Container Engine (CCE): CCE provides managed Kubernetes clusters. The exam tests CCE at the conceptual level: what Kubernetes components HUAWEI CLOUD manages (the control plane: API server, etcd, scheduler, controller manager), what the customer manages (worker nodes and deployed applications), and when CCE is preferable to managing ECS instances directly (containerized applications that need orchestration, rolling updates, and self-healing capabilities).

Domain 3: Network Cloud Services (20%)

Virtual Private Cloud (VPC)

VPC fundamentals: A VPC is an isolated virtual network within HUAWEI CLOUD where the customer controls the IP address range, subnet configuration, and routing. Resources in the same VPC can communicate by default; resources in different VPCs cannot communicate unless explicitly connected.

Subnets: VPCs are divided into subnets – smaller CIDR blocks within the VPC address range. Each subnet is associated with one Availability Zone. Resources deployed in a subnet inherit the subnet’s AZ assignment. The exam tests subnet planning: security segmentation (web tier, application tier, and database tier in separate subnets), AZ distribution (subnets in different AZs for high availability), and address range allocation.

Security Groups: Security Groups act as virtual firewalls at the instance level. Rules define which traffic is permitted by protocol, port, and source/destination. Security Groups are stateful: if inbound traffic is permitted, the corresponding outbound reply is automatically permitted without an explicit outbound rule. The default behavior: all inbound traffic is denied unless explicitly permitted; all outbound traffic is permitted unless explicitly denied. Multiple Security Groups can be associated with a single ECS instance – the combined rules determine effective access.

Elastic IP (EIP): A static public IPv4 address that can be associated with an ECS instance, ELB, or NAT Gateway for internet access. EIPs are associated with and disassociated from resources independently – the same EIP can be moved between resources. Bandwidth can be configured per EIP. The exam tests when EIP is required (internet-facing services) versus when NAT Gateway is more appropriate (many instances needing outbound internet access without individual public IPs).

NAT Gateway: Provides outbound internet access for multiple ECS instances in a VPC subnet without requiring individual EIPs. SNAT (Source Network Address Translation) rules map multiple private IPs to one or more EIPs for outbound connections. DNAT (Destination Network Address Translation) rules forward specific inbound connections to internal instances. The exam tests SNAT versus DNAT use cases and when NAT Gateway is preferable to assigning EIPs directly to each instance (cost efficiency, security – internal instances are not directly exposed to the internet).

Elastic Load Balance (ELB): Distributes incoming traffic across multiple ECS instances for high availability and horizontal scaling. The exam tests ELB listener configuration (which protocol and port the load balancer listens on), backend server group configuration (which ECS instances receive traffic and at what weight), and health check configuration (how ELB determines which backend instances are healthy and should receive traffic). An unhealthy instance is removed from rotation until its health check passes again.

VPC Peering: Connects two VPCs to enable private traffic between them – traffic stays on HUAWEI CLOUD’s internal network without traversing the public internet. Peering is non-transitive: if VPC-A peers with VPC-B and VPC-B peers with VPC-C, traffic from VPC-A cannot reach VPC-C through VPC-B. Each pair of VPCs must have its own direct peering connection. The exam tests this non-transitivity explicitly.

VPN Gateway: Creates an encrypted IPsec tunnel between the HUAWEI CLOUD VPC and an on-premises network or another cloud network. Appropriate for hybrid connectivity where dedicated physical connection is not justified by cost or traffic volume. The exam tests VPN versus Direct Connect: VPN uses existing internet infrastructure (variable latency, lower cost); Direct Connect uses a dedicated physical connection (predictable latency, guaranteed bandwidth, higher cost).

Domain 4: Storage Cloud Services (20%)

Object Storage Service (OBS)

What OBS provides: OBS stores unstructured data (files, images, videos, backups, log archives) as objects in buckets. Access is via REST API (HTTP/HTTPS) – there is no file system or directory hierarchy, only flat object storage with key names. OBS is appropriate for massive, unstructured data sets where objects are accessed by application code rather than mounted as a file system.

OBS storage classes: Standard (frequently accessed data, higher cost, no retrieval fee), Infrequent Access (less frequently accessed, lower storage cost, retrieval fee applies), Archive (rarely accessed, lowest storage cost, long retrieval time – hours for thaw). The exam tests which class is appropriate for which data access pattern.

OBS versioning and lifecycle rules: Object versioning retains multiple versions of an object when it is updated – enabling recovery of previous versions. Lifecycle rules automatically transition objects to lower-cost storage classes after a defined period and delete objects after a defined age. The exam tests versioning configuration and the combined use of versioning with lifecycle rules.

OBS access control: Bucket policies control access at the bucket level. ACLs control access at the individual object level. IAM policies control access based on the user’s identity. The exam tests the layered access control model and when each mechanism is appropriate.

Elastic Volume Service (EVS)

What EVS provides: EVS provides persistent block storage volumes that attach to ECS instances. Unlike OBS (accessed via API from any location), EVS volumes are mounted to a specific ECS and accessed like a local disk. EVS is appropriate for: database files (RDS data volumes, self-managed databases), application data that requires low-latency block access, OS volumes, and data warehouse storage.

EVS is not appropriate for: Massive video and image file sharing – that is OBS. EVS volumes attach to a single ECS (standard EVS) and are not designed for simultaneous shared access. The exam tests this exclusion: which scenario is NOT an appropriate EVS use case? Massive video and image file sharing is the correct answer.

EVS storage types: High I/O (SSD-based, for production databases and critical workloads), Ultra-High I/O (NVMe SSD, for highest performance databases and HPC storage), and General Purpose (for development, testing, and cost-sensitive workloads).

EVS snapshots and backups: Snapshots are point-in-time copies of an EVS volume stored in OBS – fast to create, storage-efficient (only changed blocks stored). Backups through Cloud Backup and Recovery (CBR) store full volume copies that are independent of the original volume’s health – appropriate for disaster recovery. The exam tests snapshot versus backup: snapshots are for quick recovery of logical errors; full backups protect against storage infrastructure failure.

Scalable File Service (SFS)

What SFS provides – and what it does not require: SFS provides shared network file storage accessible by multiple ECS instances simultaneously using NFS (Network File System) protocol. The key characteristics the exam tests: SFS supports shared access from multiple ECS instances at the same time (unlike EVS, which attaches to one instance), SFS can be used independently without requiring attachment to any specific ECS instance (the confirmed false statement tests this), and SFS stores files in a hierarchical directory structure (unlike OBS, which stores objects without hierarchy).

When SFS is appropriate: Shared application code repositories accessible by multiple application servers, shared media processing pipelines where multiple processing nodes need access to the same input files, content management systems with shared file storage, and any workload requiring simultaneous file system access from multiple instances.

SFS versus EVS versus OBS selection: The exam tests the three-way selection: use OBS for unstructured data accessed via API from any location; use EVS for block storage requiring low-latency access from a single ECS; use SFS for file system storage requiring simultaneous shared access from multiple ECS instances.

Domain 5: HUAWEI CLOUD O&M Basics (15%)

Cloud Eye (CES): Monitors HUAWEI CLOUD resource metrics (ECS CPU utilization, memory, network throughput, disk I/O; OBS request rates; ELB connection counts). Alarms fire when metrics breach configured thresholds. The exam tests alarm configuration: selecting the metric, setting threshold and evaluation period (how many consecutive data points must breach before the alarm fires), and setting the notification action (SMN topic for email/SMS notification, or triggering an Auto Scaling action).

Application Operations Management (AOM): Application-layer monitoring that tracks application performance, collects application logs from running applications, and provides a unified view of application health across multiple ECS instances and containers. The exam tests AOM versus Cloud Eye: Cloud Eye monitors infrastructure metrics; AOM monitors application-level behavior.

Log Tank Service (LTS): Centralized log collection and analysis platform. LTS ingests logs from ECS instances (via log collection agent), CCE containers, and HUAWEI CLOUD services. Log groups organize logs from related sources; log streams organize log records within a group. The exam tests a confirmed false statement about LTS: “A log group is the basic unit of log read and write.” This is false – the log stream is the basic unit of log read and write within LTS, not the log group. Log groups are the organizational container; log streams are where data is written and read.

Cloud Trace Service (CTS): Records all API operations performed on HUAWEI CLOUD resources – creating, modifying, and deleting resources – with the user identity, timestamp, source IP, and result of each operation. CTS serves as the audit trail for security investigation and compliance reporting.

Domain 6: Database, Security, CDN, and EI Services (10%)

Relational Database Service (RDS): Managed database service for MySQL, PostgreSQL, and Microsoft SQL Server. The exam tests RDS advantages: no hardware or software procurement needed, payment by resource usage, automatic backups and patch management, primary-standby replication for high availability, and read replicas for read scaling.

DRS (Data Replication Service): Migrates data between databases – from on-premises to HUAWEI CLOUD RDS, between RDS instances of the same type (homogeneous migration), or between different database types (heterogeneous migration). The exam tests DRS use cases: online migration with minimal downtime, one-time full migration, and continuous synchronization for active-active deployments.

Anti-DDoS: Provides protection against volumetric distributed denial-of-service attacks on public IP resources. The exam tests Anti-DDoS as an always-on protection service that automatically detects and mitigates attacks without requiring manual intervention.

Content Delivery Network (CDN): Distributes content to edge nodes geographically close to end users for reduced access latency. Appropriate for globally distributed users accessing large or static content (web assets, software downloads, video streaming). Origin pull retrieves content from the origin server (OBS bucket or ECS) when it is not cached at the edge. The exam tests when CDN is appropriate (global users, large content, latency sensitivity) and when it is not (content accessed by a small, geographically concentrated user base where CDN overhead exceeds benefit).

Enterprise Intelligence (EI) Services: ModelArts for AI model development and deployment, OCR (Optical Character Recognition), NLP (Natural Language Processing), and other AI service categories. The exam tests these at the awareness level – what each service category does – rather than configuration detail.

5 Study Tips for Huawei H13-811_V3.5

• Tip 1: Study the storage service boundaries with precision: OBS for API-accessed objects, EVS for block storage attached to one ECS, SFS for shared file storage accessed by multiple ECS simultaneously. Know the confirmed false statement: SFS does NOT require attachment to an ECS.
• Tip 2: Study the false LTS statement: “A log group is the basic unit of log read and write” is false – log streams are the basic unit. The exam uses confirmed false-statement question types, and knowing the frequently tested incorrect options is exam-relevant preparation.
• Tip 3: Study VPC Peering non-transitivity precisely: A peers with B and B peers with C does not mean A can reach C. Each pair needs a direct peering connection. This is a frequently tested network behavior.
• Tip 4: Study BMS characteristics specifically: applicable to HPC, gene sequencing, and AI scenarios – not to “light office scenarios such as enterprise OA.” The exam tests BMS applicability with specific scenario matching.
• Tip 5: Practice with Cert Empire’s H13-811_V3.5 exam questions testing service-specific precision, confirmed false-statement identification, and scenario-to-service matching at the HCIA exam’s applied level.

FAQ’s

What is the Huawei H13-811_V3.5 certification?

H13-811_V3.5 is the HCIA-Cloud Service V3.5 exam – the entry-level HUAWEI CLOUD certification validating foundational knowledge of cloud computing concepts and HUAWEI CLOUD services across compute, networking, storage, O&M, and database/AI domains.

Can SFS be used without attaching it to an ECS?

Yes. SFS is a shared network file system service that multiple ECS instances can mount simultaneously using NFS protocol. It does not require attachment to any individual ECS and can exist independently. The statement “SFS cannot be used independently; it must be attached to an ECS” is false – a confirmed exam question tests knowledge of this fact.

What is the difference between EVS and SFS?

EVS (Elastic Volume Service) provides block storage that attaches to a single ECS instance and is accessed like a local disk. SFS (Scalable File Service) provides shared network file storage accessible by multiple ECS instances simultaneously using NFS protocol. EVS is for per-instance storage; SFS is for shared access across multiple instances.

What is the basic unit of log read and write in LTS?

The log stream is the basic unit of log read and write in LTS. Log groups are the organizational container that groups related log streams. The statement “a log group is the basic unit of log read and write” is a false statement that the exam tests.

How long is the H13-811_V3.5 certificate valid?

3 years. The certificate can be renewed by re-passing the H13-811 exam or passing an HCIP or HCIE exam in the Cloud Service domain before the credential expires.
