Pass the Huawei HCIP-Cloud Computing H13-527_V5.0 Questions and answers with Dumpstech

The statement is FALSE . Official OpenStack Heat documentation says that when the Orchestration service was originally introduced, it worked with AWS CloudFormation templates , which are in JSON format. It then states that Heat also runs HOT templates written in YAML . This directly disproves the claim that both HOT and CFN templates support YAML in the same native sense.

OpenStack Heat documentation also explains that HOT was introduced to replace the Heat CloudFormation-compatible format (CFN) as the native format supported by Heat over time. That means HOT, not CFN, is the format more suitable for OpenStack-native deployments. The documentation further notes that YAML is easier to write, parse, and maintain, which is one reason HOT became the preferred OpenStack format.

Although internal parsing code shows the API can accept a JSON- or YAML-formatted document in some contexts, the OpenStack-native orchestration model clearly favors HOT and identifies CFN as the older CloudFormation-compatible format. So the combined statement is incorrect, and the correct answer is B (FALSE) .

After correcting the wording, the best verified answer is C . Standard Huawei OBS access methods include the console , RESTful APIs , and SDKs . Huawei OBS documentation and related Huawei service guides consistently describe OBS as being accessed through API-based methods and software-development toolkits, and many Huawei cloud services explicitly reference RESTful and SDK interaction with OBS resources.

Option C is different. Although some Huawei cloud-native scenarios allow OBS buckets to be mounted to workloads in CCE through OBS volumes, that is a specialized container-storage integration scenario, not the standard administrator access method for OBS itself. Huawei’s CCE documentation also warns about constraints and resource overhead when OBS buckets are mounted to workloads, which reinforces that this is not the normal general-purpose way an administrator “accesses OBS.”

So for exam-style classification, A , B , and D are the normal access methods, while C is not the standard answer. Therefore, the correct answer is C .

========

The statement is TRUE . Official OpenStack documentation describes Cinder, the Block Storage service, as providing on-demand, self-service access to block storage resources via abstraction and automation on top of other block storage devices . That wording is important because it shows that Cinder is not itself a physical storage technology . Instead, it presents a unified service layer that works with many different backend storage systems through drivers.

OpenStack storage architecture documentation also explains that Block Storage supports multiple back ends in the form of drivers , and the actual storage implementation depends on the chosen backend technology. In other words, Cinder exposes APIs and management functions for volumes, snapshots, and related features, while the real block storage is delivered by backend platforms such as SAN, distributed storage, or vendor storage arrays.

This matches Huawei Cloud Stack storage concepts as well, where cloud services are typically built on an abstraction layer to unify heterogeneous resources. Therefore, the correct answer is A (TRUE) , because Cinder serves as an abstraction and orchestration layer over underlying block storage systems rather than being the storage technology itself.

========

The statement is TRUE . In OpenStack Neutron, VXLAN uses a VNI (VXLAN Network Identifier) as the segmentation identifier for overlay networks. Official OpenStack Neutron configuration references describe vni_ranges as the range of VXLAN VNI IDs available for tenant network allocation , which confirms that the VNI is the central identifier used for VXLAN-based Neutron networks.

OpenStack networking documentation also explains that Neutron supports project networks and allows different projects to use overlapping IP spaces while remaining logically separated. In VXLAN/GRE tunnel realizations, OpenStack documents refer to a logical switch identifier being used to differentiate tenant traffic on inter-hypervisor tunnels , which is the practical mechanism for tenant isolation.

So, in Huawei Cloud Stack or any OpenStack-based multi-tenant cloud, the VNI functions as the unique overlay-network identifier that keeps one tenant’s VXLAN traffic separate from another tenant’s traffic. That is why the statement is correct and the verified answer is A (TRUE) .

========

The correct answer is C. Quick and elastic adjustment of CPUs and memory . Huawei’s official HUAWEI CLOUD Stack materials describe Bare Metal Server (BMS) as dedicated physical servers that provide excellent or remarkable computing performance and direct access to physical resources. Huawei also explains that Ironic works with Nova and Neutron to manage BMS resources, highlighting the physical-server nature of the service. These characteristics support advantages such as physical isolation , no hypervisor performance overhead , and direct access to specialized hardware .

By contrast, Huawei’s ECS Advantages documentation explicitly says that with ECS, administrators can modify an ECS flavor, including the number of CPUs and memory size . That kind of quick and elastic CPU/memory adjustment is therefore an ECS advantage , not a BMS-over-ECS advantage.

So after correcting the option formatting, A , B , and D are all real BMS strengths, while C belongs more to virtualized ECS elasticity. Therefore, the verified answer is C .

Data analysis platform → Eliminate data silos and unify metric models

Configuration management platform (CMDB) → Store and manage a wide variety of information about devices and systems in the enterprise IT architecture

AutoOps automation platform → Atomic operations can be orchestrated and then be executed

Agent and driver interconnection → The purpose is to implement full data access

Comprehensive and Detailed 150 to 200 words of Explanation From HUAWEI CLOUD Computing Topics:

This matching follows the normal functional roles of Huawei Cloud Stack O & M platforms. The data analysis platform is used to integrate monitoring and operational data from different domains, so its purpose is to eliminate data silos and unify metric models . The CMDB is the configuration management database, whose core role is to store and manage configuration and relationship information about devices, systems, and services across the enterprise IT architecture.

The AutoOps automation platform is designed for automated O & M execution. In Huawei Cloud Stack operations, this includes arranging standardized or atomic O & M tasks into executable workflows, so the description atomic operations can be orchestrated and then be executed correctly matches AutoOps. The agent and driver interconnection layer is the connectivity and collection mechanism used to connect tools, devices, and services so that data can be gathered comprehensively. Therefore, its purpose is to implement full data access .

So the final verified mapping is: data analysis platform = unified metrics , CMDB = configuration information management , AutoOps = orchestration and execution of atomic operations , and agent/driver interconnection = full data access .

The statement is TRUE . In HUAWEI CLOUD Stack, a resource set is a logical grouping of cloud resources under a tenant or VDC for purposes such as authorization, organization, and management. Huawei documentation describes resource sets as being used to classify and manage resources within a tenant context, which means their scope is tied to the tenant’s own resource domain. This is why resource sets are commonly used to separate production, test, departmental, or project resources inside the same tenant or VDC rather than as a cross-tenant migration mechanism. ( )

Operationally, resources can be reassigned or moved between resource sets when administrators need to reorganize management boundaries, but the resource-set model itself is not designed to move resource sets across tenants . Cross-tenant transfer would break the tenant-based isolation and authorization structure that Huawei Cloud Stack uses for cloud governance. This is consistent with Huawei’s hierarchical cloud management approach, where tenants are major security and administration boundaries, while resource sets are subordinate organizational tools. Therefore, the verified answer is A (TRUE) because resource migration between resource sets is allowed within the management domain, but resource sets themselves are not intended for migration across tenants.

The correct answer is D. Virtual Private Network (VPN) . Huawei’s official HUAWEI CLOUD Stack VPN documentation states that a VPN connection is an encrypted communications channel established between the VPN gateway in a VPC and the gateway in an external or local data center. Huawei also describes VPN as a way to connect a local data center to cloud resources through a secure and reliable encrypted tunnel over the Internet . This directly matches the requirement in the question for encrypting connections between cloud resources and local data centers.

By contrast, Direct Connect provides a dedicated, high-speed, low-latency connection, but the cited Huawei description emphasizes dedicated connectivity and stability rather than the VPN-style encrypted tunnel itself. EIP is only a public IP addressing service, and VPCEP is used for private access to services, not site-to-cloud encrypted interconnection. For small- and medium-sized enterprises that want a practical, secure, and relatively simple hybrid-cloud connection, Huawei documentation supports VPN as the best fit. Therefore, the verified answer is D .
