H13-811_V3.5 Exam Dumps - HCIA-Cloud Service V3.5

All four categories form part of Huawei Cloud's layered security architecture. Network security includes controls and services designed to protect network boundaries and traffic, such as Anti-DDoS, Advanced Anti-DDoS, VPC security controls, firewalls, and network isolation. Huawei Cloud describes network security as a core component of its full-stack cloud defense model.

Application security protects web applications and application-layer traffic. Representative Huawei Cloud services include Web Application Firewall, which detects and blocks HTTP/HTTPS attacks, and application vulnerability/security capabilities.

Computing security covers server and workload protection. Host Security Service protects ECS and other server workloads through vulnerability management, intrusion detection, account-security controls, malware detection, and web tamper protection. Security-management capabilities such as Cloud Bastion Host and centralized security operations provide access management, authentication, authorization, auditing, and operational control.

Finally, data security encompasses encryption, database protection, identity/access control, sensitive-data protection, and lifecycle safeguards. Huawei's security architecture explicitly identifies protection of confidentiality, integrity, availability, durability, and traceability as data-security objectives.

Therefore, A, B, C, and D are all included .

Huawei Cloud establishes a clear parent-child relationship between a Huawei Cloud account and the IAM users created under that account. The account owns the cloud resources and is the billing entity , whereas IAM users consume or manage resources according to permissions assigned by the account administrator.

Therefore, option C is correct: IAM users do not independently pay for the resources they use. Charges generated through their authorized operations are billed to the parent account. Options B and D are also correct because the account administrator retains authorization control and can modify or revoke permissions assigned to IAM users.

Option A is incorrect because it incorrectly treats the IAM user as a payment entity. Authorization determines what an IAM user is permitted to access or operate , not who is responsible for payment. Huawei Cloud explicitly distinguishes resource ownership and billing from delegated resource access. An IAM user does not receive an independent bill merely because access to a resource has been authorized.

Accordingly, the correct relationship is: account owns and pays; IAM users operate resources according to delegated permissions; the account controls those permissions .

The mappings follow Huawei Cloud's system-defined authorization model for Bare Metal Server. BMS CommonOperations provides operational permissions required for routine server administration. Huawei explicitly identifies starting, stopping, restarting, and querying BMS instances as operations permitted under the common-operations permission set. It therefore maps to permission 2.

BMS FullAccess represents administrator-level access to the BMS service. It permits operations that CommonOperations and ReadOnlyAccess cannot perform, including higher-impact lifecycle and configuration operations. Huawei Cloud's BMS permission matrix shows that reinstalling a BMS operating system is supported by FullAccess but not by CommonOperations or ReadOnlyAccess. Consequently, BMS FullAccess maps to permission 1.

BMS ReadOnlyAccess is intended for users who need visibility into BMS resources without authority to modify them. It permits users to query and view BMS information, including server lists and instance details, but does not authorize lifecycle actions such as starting, stopping, restarting, or reinstalling an operating system. It therefore maps to permission 3.

The verified mapping is CommonOperations → routine operations; FullAccess → OS reinstallation; ReadOnlyAccess → viewing BMS information .

Option A is correct . Huawei Cloud Elastic Load Balance provides several traffic-distribution algorithms, including weighted round robin, weighted least connections, and source IP hash for shared load balancers. When backend servers have equal weights under weighted round robin, they receive an equal proportion of requests, providing the even traffic distribution described in the question.

Auto Scaling and ELB are explicitly integrated. When an AS group is associated with a load balancer, Huawei Cloud automatically associates newly added ECS instances with the load balancer and removes the association when instances leave the AS group. Therefore, option C is false; administrators do not need to manually register each dynamically created instance one by one.

Option B is incorrect in this context because the load balancer and its AS resources operate within the applicable regional/VPC deployment architecture; a standard shared ELB is not a mechanism for arbitrary cross-region backend distribution. Option D is also false because detecting unhealthy instances depends upon an enabled health-check mechanism. Disabling health checking removes the basis for making that health determination.

===============

The statement is FALSE . Huawei Cloud explicitly supports using VPN to establish communication between VPCs deployed in different regions . The Huawei Cloud VPC FAQ describes this architecture directly: VPCs in the same region can be connected by VPC peering, while VPCs in different regions can establish connectivity through VPN. In the VPN design, each VPC uses a VPN gateway, and the two gateways establish an encrypted connection over the Internet. The VPC CIDR blocks are configured as the local and remote subnets.

This distinction is central to the HCIA V3.5 networking domain. VPC peering is region-scoped : two VPCs connected through a peering connection must reside in the same region. VPN, by contrast, can establish encrypted connectivity between geographically separated VPC networks. Huawei's VPN documentation specifies creating a VPN gateway for each VPC, creating VPN connections, configuring the peer gateway EIP, defining peer subnets, and applying matching cryptographic parameters.

Consequently, saying that Huawei Cloud VPN “does not support” cross-region VPC communications directly contradicts the supported VPN deployment model.

The statement is TRUE . Huawei Cloud makes an explicit architectural distinction between Elastic Cloud Servers and Bare Metal Servers regarding the underlying compute resources. An ECS is a virtualized compute instance. Multiple ECS instances can therefore consume resources provided by the same underlying physical host, with virtualization providing logical isolation between tenants and workloads.

A BMS, by contrast, provides exclusive access to physical compute resources. Huawei Cloud states directly that BMS users can exclusively access physical resources, whereas ECS users share those physical resources. This makes BMS particularly suitable for mission-critical systems, big-data clusters, enterprise middleware, high-performance workloads, and applications that require predictable performance or direct access to physical CPU and memory resources.

Huawei's BMS comparison also identifies Exclusive resources = Yes for BMS and traditional physical servers, but No for ECS. BMS additionally provides cloud characteristics such as automatic provisioning, VPC integration, image-based deployment, monitoring, and cloud storage while retaining physical-server performance.

Therefore, the differentiation presented in the question is technically accurate.

===============

Scalable File Service (SFS) is the precise Huawei Cloud service for this workload. The wording in the question closely follows Huawei's official media processing application scenario for SFS. Huawei specifically lists streaming media, archiving, editing, transcoding, content distribution, and video on demand as representative media-processing workloads.

The decisive requirement is that multiple hosts must access the same media files concurrently. SFS provides shared file storage that can be mounted by multiple ECSs or other supported compute resources through standard file protocols. Applications then interact with the storage through normal directories and file-system semantics. This eliminates the need to redesign media-processing applications around object-storage APIs.

OBS is highly scalable and well suited to object storage, content distribution, archive, and VOD data, but applications access OBS through HTTP/HTTPS, APIs, or SDKs rather than through a conventional shared filesystem. EVS provides block storage and generally must be attached to a server; ordinary EVS is not the direct multi-host shared file-system solution. Huawei's storage-selection guidance identifies SFS specifically for media processing and file sharing.

Therefore, B. SFS best satisfies the shared-media workflow.

===============

Statement C is incorrect in the HCIA-Cloud Service V3.5 IMS model. Huawei Cloud does not impose a standalone service charge simply for using the core Image Management Service functions such as creating a standard private image. Huawei's official getting-started documentation explicitly states that creating a private image is free . Charges may nevertheless arise from dependent resources associated with image usage.

This distinction explains option A. Depending on the image and deployment model, costs can be associated with licensed operating systems, storage used for image files, backups, OBS objects, or other dependent cloud resources. These costs do not make IMS itself a separately charged service.

Option B correctly reflects the principal image categories taught in the HCIA course: public images, private images, and shared images . Marketplace images are additionally available as third-party packaged offerings but do not invalidate this fundamental IMS classification.

Option D also correctly describes the role of an image. Images provide standardized operating environments and can include the operating system, pre-installed applications, configuration data, and user applications. They can then serve as templates for rapidly creating ECS instances with consistent software configurations.

Accordingly, the incorrect statement is C .
