Free and Premium Huawei H13-811_V3.5 Dumps Questions Answers

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 .

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

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.

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

The statement is FALSE . Although an ECS group does logically organize ECS instances, its placement behavior is the opposite of what the second sentence states. Huawei Cloud ECS groups support the anti-affinity policy , which is designed to place ECS instances belonging to the same group on different physical hosts .

Anti-affinity is an availability and fault-isolation mechanism. If multiple application instances were placed on one physical server, failure of that host could simultaneously disrupt every application instance. Distributing the ECSs across different hosts reduces this correlated-failure risk and improves service reliability, high availability, and disaster tolerance.

Huawei's ECS documentation explicitly states that ECS groups support the anti-affinity policy and that ECSs in an anti-affinity group are deployed on different hosts. When an existing ECS is added to such a group, Huawei Cloud may even reallocate its host so that the placement requirement can be maintained.

Therefore, the first proposition—an ECS group logically groups ECSs—is valid. However, the assertion that ECSs in that group are created on the same physical server by default contradicts the anti-affinity design. Since the overall statement contains this incorrect condition, the correct answer is FALSE .

Reference topics: ECS Groups; Anti-Affinity Policy; Host Placement; High Availability.

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

The statement is false because its description of infrastructure ownership does not correctly characterize a hybrid cloud. A hybrid cloud combines different cloud environments—most commonly private cloud and public cloud —and enables workloads, applications, or data to be distributed between them according to security, capacity, latency, compliance, or business requirements.

Huawei Cloud describes hybrid cloud as a blend of private and public cloud environments. The private portion may be dedicated to a particular customer and may host confidential or sensitive workloads, while public cloud resources are delivered through infrastructure operated by a cloud service provider. Consequently, the combined infrastructure is not inherently owned and operated by a single organization .

This ownership distinction separates hybrid cloud from a purely private-cloud model. A private cloud can be dedicated to a single organization, whereas hybrid architecture deliberately combines environments that may have different infrastructure ownership and operating responsibility.

The statement correctly recognizes that hybrid cloud is flexible and that workloads can use different cloud environments, but because it makes an absolute and incorrect assertion about single-organization ownership, the entire statement must be evaluated as FALSE .

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

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.

Reference topics: Virtual Private Network; Cross-Region VPC Connectivity; VPC Peering; VPN Gateways.

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

Options B and C are incorrect because they reverse the isolation characteristics of IAM projects and enterprise projects . Huawei Cloud defines enterprise projects as a mechanism for grouping and managing resources across regions. Resources assigned to different enterprise projects are logically isolated , and a single enterprise project can contain resources residing in multiple regions. Supported resources can also be added to, removed from, or transferred between enterprise projects. Consequently, statements A and D correctly describe Enterprise Project Management.

IAM projects operate differently. Huawei Cloud documentation states that IAM projects are region-oriented and are used to group and physically isolate resources within a region . A project corresponds to a region, and an IAM project does not provide the cross-region logical grouping model associated with enterprise projects.

Therefore, B is wrong because it attributes physical, same-region isolation to enterprise projects, while C is wrong because it attributes logical isolation to IAM projects. The two concepts are intentionally distinguished in Huawei Cloud architecture: IAM project = regional/physical isolation; enterprise project = cross-region/logical resource organization .

Reference topics: IAM Projects; Enterprise Projects; Resource Isolation; Enterprise Management.

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

Memory-optimized ECSs are specifically designed for the workload described. Huawei Cloud defines memory-optimized ECSs as instances that excel at processing large in-memory datasets and high-throughput networking . They are intended for memory-intensive workloads involving large datasets, frequent or heavy data access, and requirements for rapid data processing and exchange.

The scenario deliberately combines several identifying characteristics: large-memory datasets, substantial data volumes, high numbers of access requests, demanding network performance, and rapid data transfer and processing. These characteristics correspond directly to the design profile of the memory-optimized ECS family. Huawei lists representative applications such as high-performance databases, in-memory databases, distributed memory caches, data analysis and mining, Hadoop, Spark, e-commerce, and other enterprise applications.

Ultra-high I/O instances emphasize extremely high storage IOPS and low disk latency. High-performance computing instances are optimized primarily for compute-intensive scientific or engineering workloads. Although “large-memory” may appear plausible, memory-optimized is the ECS category whose official description explicitly combines large in-memory datasets with high-throughput networking and heavy data access.

Therefore, D is the precise Huawei Cloud classification required by the scenario.

Reference topics: ECS Types and Specifications; Memory-Optimized ECSs; Memory-Intensive Workloads; High-Throughput Networking.

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

Option B is incorrect . Huawei Cloud explicitly requires subnet CIDR blocks within the same VPC to be unique and not overlap . Allowing overlapping subnets would make local route selection ambiguous and create address conflicts inside the VPC. Huawei's subnet definition therefore states that subnets in a VPC cannot overlap with each other.

Option A is correct for subnet planning: Huawei advises users to plan subnet address ranges carefully because a subnet's CIDR block cannot be changed after creation. This is why future capacity requirements should be considered before allocating subnet prefixes.

Option C is also consistent with Huawei's VPC definition. A subnet represents a unique CIDR block containing an IP address range inside a VPC, and VPC resources requiring private networking are deployed into these subnets. Option D is correct because the subnet CIDR must fall within the VPC's address range. Huawei's network-planning guidance explicitly states that the subnet CIDR block must be within the VPC CIDR block and that subnet CIDR blocks in the VPC must be unique.

Thus, the only incorrect planning statement is B .

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

For the HCIA-Cloud Service V3.5 curriculum version , statements A, B, and C are correct . An ECS must be associated with a security group so that inbound and outbound network access can be controlled. If an account has no custom group, Huawei Cloud provides a default security group, and users can either use that default group or create and select another security group that matches the workload's security requirements.

The V3.5-era Huawei Cloud VPC documentation distinguishes security groups from network ACLs by stating that security groups provide allow rules , whereas network ACLs provide both allow and deny rules. This distinction is important because it appears repeatedly in the HCIA V3.5 networking curriculum.

Statement D is false. Huawei Cloud specifically permits administrators to modify existing rules or add rules to the default security group . The default group itself cannot normally be deleted, but that restriction does not make its inbound or outbound rules immutable. Huawei's default-security-group documentation explicitly distinguishes group deletion restrictions from rule modification permissions.

Reference topics: VPC Security Groups; ECS Network Configuration; Default Security Group; Security Group Rules.

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

Option A is incorrect because Huawei Cloud Auto Scaling is designed to automatically adjust ECS instances and bandwidth resources , not Bare Metal Server instances. Huawei's AS documentation defines an AS group as a collection of ECS instances and states that scaling actions add or remove ECS instances according to alarm, scheduled, or periodic policies. BMS provides dedicated physical compute and is provisioned through the BMS service rather than being dynamically created and destroyed by an ECS Auto Scaling group.

The other relationships are valid. Cloud Eye supports BMS operating-system monitoring after the Cloud Eye Agent is installed; the BMS reports detailed CPU, memory, disk, and network metrics to Cloud Eye. EVS is integrated with BMS and additional supported EVS data disks can be attached when more storage is required. IMS is likewise an integral BMS service: images can be used to create consistently configured BMSs and to reinstall or change their operating systems, reducing repetitive deployment work. Huawei's BMS architecture explicitly lists VPC, IMS, EVS, Cloud Eye, and backup services as integrations supporting BMS operation.

Reference topics: Bare Metal Server Architecture; BMS and Other Cloud Services; Auto Scaling; Cloud Eye; IMS; EVS.

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

The major CTS functions represented by the options are trace recording, trace query, and trace transfer , making A, B, and D correct.

Trace recording captures operations performed through the Huawei Cloud management console, through APIs, and operations initiated by supported cloud services. These records provide an audit trail containing information such as the operator, operation time, resource, operation result, and associated request data.

Trace query allows administrators and auditors to search recent operational records on the CTS console using criteria such as trace source, resource type, operator, trace status, and operation type. This is essential for security auditing, compliance investigation, and troubleshooting.

Trace transfer provides longer-term retention and centralized analysis. CTS can package operation records into trace files and transfer them to supported destinations such as OBS or LTS for preservation and subsequent processing.

Option C, OS monitoring , does not belong to CTS. Operating-system performance monitoring is primarily a Cloud Eye/server-monitoring capability rather than an audit-trace function.

Huawei's official CTS documentation expressly identifies recording, querying, and transfer among its core service functions.

Reference topics: Cloud Trace Service; Trace Recording; Trace Query; Trace Transfer; Cloud Auditing.

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

Options B, C, and D identify problems that CDN architecture is designed to mitigate. Huawei defines CDN as an intelligent virtual network built on Internet infrastructure that caches origin content on geographically distributed points of presence close to users. This substantially shortens the network path between users and frequently requested resources.

Consequently, CDN improves download speed because users can retrieve cached files from a nearby edge PoP rather than repeatedly crossing long-distance networks to the origin server. It also addresses slow website access by accelerating static content delivery, reducing latency, and improving site response and availability. Huawei specifically states that CDN breaks through bottlenecks associated with limited bandwidth, high access traffic, and uneven network-node distribution.

Caching popular content at edge nodes also reduces repeated traffic flowing through core and backbone networks. This alleviates bandwidth pressure on both the origin infrastructure and long-distance network paths.

Option A is not a CDN problem statement. CDN commonly reduces origin-server load , meaning utilization of origin resources may decrease rather than fixing a problem described as “low server utilization.” Its purpose is acceleration and traffic offloading, not increasing server utilization.

Therefore, B, C, and D are correct.

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

Option A is false because deleting historical object versions is not required before versioning can be suspended. Huawei Cloud states that once versioning has been enabled, it cannot revert to the original Disabled state, but it can be suspended. Existing historical versions remain stored in OBS after suspension and may be manually deleted later only if they are no longer required.

Option B is correct. When versioning is enabled, OBS automatically assigns a unique version ID to newly uploaded versions. Objects with identical names are retained as separate object versions distinguished by those IDs.

Option C is also correct. Huawei explicitly supports configuration of OBS versioning through the OBS Console, APIs, and SDKs.

Option D is correct because versioning is disabled by default for newly created buckets. It must be explicitly enabled if the customer wants multiple versions retained instead of allowing a newly uploaded namesake object to replace the current object.

Therefore, A incorrectly adds a prerequisite that Huawei does not impose for suspending versioning.

Reference topics: OBS Versioning; Version IDs; Suspending Versioning; Historical Object Versions.

All four options are valid Huawei Cloud CTS functions. Trace recording provides the fundamental audit capability: CTS records system-triggered operations as well as operations performed through the console or APIs. These records enable accountability, troubleshooting, security investigation, and compliance auditing.

Trace query allows users to retrieve and filter recent operation records directly on the CTS console according to attributes such as resource type, operator, trace source, operation status, and time.

Trace transfer supports longer-term preservation. CTS compresses recorded traces into trace files and periodically transfers them to configured storage or logging destinations, including OBS or LTS depending on tracker configuration.

Trace file encryption is also explicitly supported. Huawei's current CTS documentation states that trace files can be encrypted using keys provided through Data Encryption Workshop during the transfer process. This protects audit information at rest and provides stronger security for retained operation records.

This question differs slightly from asking only for the three foundational audit-processing functions; it asks broadly which options are functions of CTS , and Huawei's official function list includes encryption in addition to recording, querying, transfer, and key event notification.

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

The statement is true in the context of the HCIA cloud-computing architecture model. Cloud computing evolved from developments in computing, distributed systems, virtualization, networking, and Internet technologies. Most importantly, cloud services are consumed remotely, making network connectivity an intrinsic part of service delivery.

Huawei Cloud defines cloud services as IT capabilities delivered by cloud providers through the Internet or dedicated networks . These services include compute, storage, networking, security, database, middleware, O & M, big data, and AI resources. Users obtain and consume those resources remotely rather than requiring the underlying physical infrastructure to reside locally.

This dependence is architectural rather than merely convenient. An ECS, database, object-storage bucket, SaaS application, or cloud management interface has practical value to a remote user only if network connectivity exists between the consumer and the cloud environment. A private connection can replace Internet access in certain enterprise architectures, but that is still network connectivity.

Accordingly, the intended HCIA principle is that cloud computing and networking are inseparable: network access forms the communication foundation through which cloud resources are delivered and consumed .

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

1 → PaaS

2 → IaaS

3 → SaaS

The three mappings correspond directly to Huawei Cloud's definitions of the standard cloud service models. Infrastructure as a Service (IaaS) supplies foundational infrastructure resources such as compute, storage, and networking. Huawei Cloud services such as ECS, VPC, VPN, and OBS are representative infrastructure-level services. Therefore, the description referring to computers, storage devices, and networks maps to IaaS.

Platform as a Service (PaaS) provides managed platform capabilities used to develop, deploy, and operate applications. Huawei Cloud characterizes PaaS as including middleware, database platforms, development environments, microservice capabilities, and related application-platform resources. Consequently, the database/middleware/MySQL/MongoDB/Java-oriented description belongs to PaaS.

Software as a Service (SaaS) delivers complete applications to end users. Customers consume the application rather than maintaining the underlying operating system, middleware, runtime, and infrastructure. Enterprise applications, messaging systems, email services, collaboration applications, and similar ready-to-use software fit this model.

The correct progression is therefore PaaS → IaaS → SaaS for the three descriptions shown in the question.

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

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 .

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

Option B is incorrect because Huawei Cloud OBS does not allow a bucket that has already had versioning enabled to return to the original Disabled state. Versioning can initially be enabled on a bucket, but once enabled, it can subsequently only be suspended , not disabled.

Option A is correct. With versioning enabled, OBS assigns unique version IDs to uploaded objects, allowing multiple objects with the same key or name to coexist as different versions. This protects against accidental overwrites and provides point-in-time recovery capabilities.

Option C is also correct when a specific historical version is permanently deleted. Each object version is independently identified by its version ID, so deleting one specified version does not inherently remove the other retained versions.

Option D accurately describes the initial state. Huawei states that versioning is disabled by default for newly created OBS buckets. When versioning has never been enabled, uploading a new object with the same name replaces the existing object instead of maintaining multiple historical versions.

The critical distinction is therefore Disabled versus Suspended . Disabled is the initial state; after versioning is enabled, it cannot be restored to Disabled.
