Huawei HCIA-Cloud Service V3.5 H13-811_V3.5 Exam Dumps: Updated Questions & Answers (September 2026)

1 → Bare Metal Server (BMS)

2 → Elastic Cloud Server (ECS)

3 → Physical server

The first scenario maps to BMS because Bare Metal Servers combine exclusive access to physical resources with cloud-oriented provisioning and management. Huawei Cloud recommends BMS for key or mission-critical applications and services requiring high performance. BMS retains direct physical CPU and memory access while supporting capabilities such as automatic provisioning, VPC networking, image deployment, monitoring, and cloud storage. It therefore provides both resource exclusivity and cloud flexibility .

The second scenario maps to ECS . ECS instances operate on virtualized infrastructure, so physical server resources can be shared among virtual machines. This model is appropriate for general-purpose and specialized cloud workloads where virtualization, rapid deployment, elasticity, and efficient resource utilization are priorities.

The third scenario maps to a traditional physical server . A physical server also provides exclusive resources, but Huawei's comparison shows that traditional servers do not inherently provide cloud capabilities such as automatic provisioning, VPC integration, image-based deployment, and standardized cloud monitoring. This makes them characteristic of traditional dedicated-service environments.

Huawei's comparison explicitly records exclusive resources for BMS and physical servers, but not ECS.

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

The statement is TRUE and closely follows Huawei Cloud's official definition of Object Storage Service. OBS is a cloud-based object storage platform designed to provide scalable, secure, durable, and cost-effective storage for large volumes of unstructured data. Huawei explicitly identifies OBS as a web service that exposes APIs through both HTTP and HTTPS.

Huawei provides several access mechanisms. Administrators and ordinary users can manage buckets and objects through the OBS Console and graphical or command-line OBS tools, while application developers can integrate OBS programmatically through supported SDKs and REST APIs. This enables applications to perform operations such as object upload, download, deletion, metadata management, lifecycle configuration, access control, and multipart upload without requiring direct interaction with the management console.

Huawei also describes OBS as accessible over the Internet from different locations, subject to authentication, authorization, network, and bucket-policy controls. The SDK/API layer is specifically intended to facilitate development of upper-layer applications using OBS as persistent object storage.

Therefore, every technical assertion in the statement corresponds to the official Huawei Cloud OBS architecture and access model.

KooSearch is the Huawei Cloud service specifically designed to provide enterprise-grade search capabilities with an out-of-the-box service model. Huawei Cloud describes KooSearch as a one-stop intelligent enterprise search solution built on Cloud Search Service (CSS). It enables organizations to construct enterprise search, knowledge retrieval, AI search, and document Q & A applications without having to independently build the underlying search infrastructure. The service integrates enterprise knowledge sources, search models, vector search capabilities, and other components required for enterprise information retrieval.

This directly corresponds to the question's description of an out-of-the-box search service designed for enterprise digitalization . Huawei's current KooSearch documentation explicitly emphasizes its ready-to-use enterprise search and RAG capabilities. KooPhone is associated with cloud-phone capabilities, KooMessage concerns enterprise messaging and communication, and KooMap provides map-related services; none is the dedicated enterprise search offering.

Therefore, KooSearch is the only technically valid choice . This aligns with the HCIA-Cloud Service domain covering Huawei Cloud platform and other value-added cloud services.

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

Statements B and C are correct . Huawei Cloud Eye supports batch creation of monitoring alarms. Huawei's documented quota specifically states that up to 50 monitored objects can be selected when creating an alarm rule and that up to 1,000 alarm rules can be created at one time . Huawei even provides the exact example used here: 50 monitored objects multiplied by 20 metrics produces 1,000 alarm rules. Therefore, B is directly supported.

Statement C is also valid. Cloud Eye alarm rules can provide monitoring triggers used with Auto Scaling. An alarm-based AS policy references a Cloud Eye alarm rule; when monitored metrics meet the configured threshold condition, the corresponding scaling action can be initiated.

Statement A is false because Cloud Eye server monitoring is not limited to OS-level resource metrics. With the Agent installed, Huawei Cloud Eye also provides process monitoring , including process CPU usage, memory usage, opened files, and customized process-monitoring tasks.

Statement D is false because alarm templates and batch alarm creation eliminate the requirement to create every alarm rule individually.

Reference topics: Cloud Eye Server Monitoring; Process Monitoring; Alarm Rules; Alarm Templates; Auto Scaling Integration.

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

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.

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

The statement is TRUE . Logging is a fundamental component of cloud operation, maintenance, troubleshooting, security auditing, and lifecycle management. Huawei Cloud Log Tank Service is designed to collect and centrally process logs from a broad range of environments, including cloud services, ECSs, physical servers, containers, network-related systems, APIs, and other infrastructure components.

Huawei describes LTS as a platform for application O & M, security and compliance, and operations analysis . It provides full-stack log collection, high-speed searching, SQL analysis, visualization, alarm generation, processing, and log transfer. These capabilities allow administrators to track system behavior from deployment through normal operation, troubleshooting, scaling, upgrades, incident response, and eventual retirement.

Huawei's logging architecture also supports network-device information through protocols such as Syslog and SNMP, while ICAgent can collect logs from physical servers and ECSs. Cloud-service logs can be ingested directly from numerous Huawei Cloud services.

Logs therefore provide historical evidence and real-time operational insight throughout the lifecycle of infrastructure and applications. They are not limited to fault diagnosis after an incident; they are an integral O & M data source.

1 → C

2 → A

3 → D

4 → B

Each fault maps to a specific Huawei Cloud VPC control. A VPC cannot be deleted while dependent resources such as a VPC peering connection still use it, so scenario 1 maps to C. Huawei Cloud explicitly lists VPC peering connections among resources that must be removed before VPC deletion.

For scenario 2, merely binding an EIP does not override security-group filtering. If the relevant inbound security-group rule does not permit traffic from the source IP address and required protocol/port, the ECS remains inaccessible externally; therefore it maps to A.

Scenario 3 maps to D. Huawei Cloud uses DHCP to allocate private addresses dynamically, and its troubleshooting guidance specifically instructs administrators to verify whether the subnet's DHCP function is enabled when an ECS cannot obtain a private IP address.

Scenario 4 maps to B. Huawei documentation explicitly identifies conflicting network ACL and security-group rules as a cause of security-group rules appearing ineffective. The network ACL can block traffic that the security group otherwise permits.

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

The correct answer is D. Available. Huawei Cloud uses Cloud Backup and Recovery to create backups of EVS disks, and the source disk must be in an operational state that permits a consistent backup operation. Huawei's official CBR and EVS documentation states that EVS disk backups can be created when disks are in the Available or In-use state.

Of the states listed in this question, only Available qualifies. A disk in the Creating state has not completed provisioning. A disk in the Deleting state is being removed and cannot serve as a stable backup source. “Deletion failed” represents an exception condition requiring remediation rather than a valid backup state. Huawei's disk-status guidance instructs administrators to troubleshoot a disk in the Deletion failed state rather than perform normal storage operations on it.

An Available disk has completed creation, is not currently attached for active I/O, and is accessible for supported management operations. Huawei Cloud can therefore associate it with a disk backup vault and create a CBR backup.

Although In-use would also be supported if included among the options, it is absent here. Consequently, Available is the only valid selection.

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

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 . Huawei Cloud Image Management Service supports creating private images from external image files, with OBS serving as the staging storage location for those files. The documented workflow is to prepare the source image, upload the image file to an appropriate OBS bucket, and then register or import that file through IMS as a private image.

Huawei's IMS documentation explicitly describes the scenario as registering an image file that has been uploaded to an OBS bucket as a private image . During image creation, the administrator selects Import Image or Image File as the source, selects the OBS bucket containing the prepared file, and then selects the required file.

Supported formats and detailed constraints depend on the image type and import method. For example, standard system-disk image imports and optimized fast-import workflows have specific requirements concerning image formats, file size, operating system, and bucket storage class. However, these restrictions do not change the fundamental integration represented in the question.

OBS therefore provides object storage for the source image file, while IMS performs image registration and lifecycle management. The resulting private image can subsequently be used to provision identically configured ECS instances.
