Huawei HCIP-Cloud Computing V5.0 H13-527_V5.0 Exam Dumps: Updated Questions & Answers (April 2026)

The correct answer is B. Querying VM memory usage every 10 minutes . OpenStack Telemetry documentation states that the Telemetry service polls service APIs every 10 minutes by default , and that this interval can be changed in polling.yaml. That is exactly the behavior of a polling agent: it periodically queries metrics rather than waiting for events.

Ceilometer measurement documentation also includes metrics such as memory.usage, which shows that VM memory usage is one of the kinds of resource data that polling-based telemetry can collect, depending on configuration and hypervisor support.

The other options describe different telemetry-related functions. Reporting alarms is associated more with alarming services such as Aodh, listening to VM deletion events corresponds to event-driven notification collection rather than polling, and storing event logs is a storage or event-backend function rather than the polling agent’s role. Therefore, the typical example of a polling agent’s work is periodic metric collection, making B the fully verified answer. This also aligns with Huawei Cloud Stack monitoring and O & M concepts built on OpenStack telemetry principles.

The best verified answer is A. AutoOps built-in scripts . Huawei’s HUAWEI CLOUD Stack O & M documentation states that Automated Jobs automatically detect faults of each cloud service , and that the automation scripts or jobs of each cloud service are displayed and can be centrally managed . That makes AutoOps built-in scripts the most suitable choice for quick diagnosis when VM migration failures happen repeatedly, because this is exactly the kind of recurrent platform-side fault scenario where automated diagnosis scripts are useful.

The other tools are more specialized for different problem domains. CloudNetDebug is described by Huawei as a network diagnosis tool on virtual networks and is mainly used to detect network traffic interruption, packet loss, and full-link virtual network faults. Call chain is associated with application tracing or APM-style request tracing, not VM migration troubleshooting. ECS storage troubleshooting tools are aimed at storage-related fault analysis rather than general VM migration diagnosis.

Therefore, for fast diagnosis of frequent VM migration failures in Huawei Cloud Stack O & M, the most appropriate tool is AutoOps built-in scripts , so the verified answer is A .

The correct answer is C. SaaS. In the Software as a Service model, the cloud provider delivers a complete application that users access over the network, while the provider is responsible for installation, maintenance, upgrades, and much of the operational management. This makes SaaS especially suitable for daily office work, such as email, document collaboration, office suites, and business productivity applications. Organizations, especially small- and medium-sized enterprises, can use the software directly without managing the underlying infrastructure or platform.

By comparison, IaaS mainly provides infrastructure resources such as compute, storage, and networking, so the enterprise still needs to manage operating systems and applications. PaaS provides an application development and runtime platform, which is useful for developers but not the best fit for general office users. MaaS is not the standard answer in this classic cloud-service-model classification.

In Huawei Cloud computing training and in mainstream cloud architecture, SaaS is the service model that best matches a scenario where customers want to use software immediately and avoid the burden of software deployment and maintenance. Therefore, the verified answer is C. SaaS.

The statement is TRUE according to the official HOT specification. OpenStack Heat documentation shows the overall HOT structure and explains that heat_template_version identifies the YAML document as a HOT template of a specific version. This key is fundamental because it tells Heat which template format and feature set to validate.

The same HOT specification states that the resources section contains the declaration of the resources in the template and that this section with at least one resource should be defined in any HOT template , otherwise the template would not really do anything when instantiated. In other words, a valid HOT template intended to deploy a stack needs both the version declaration and a resource definition.

Other sections such as description, parameters, outputs, and conditions are documented as optional. That is why heat_template_version and resources stand out as the core required parts for normal HOT authoring. In Huawei Cloud Stack training contexts based on OpenStack Heat, these are treated as the mandatory structural elements of a HOT template. Therefore, the verified answer is A (TRUE) .

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 correct answer is B. ML2 Plugin . In OpenStack Neutron, ML2 stands for Modular Layer 2 and is the main core networking plugin framework used to support different network types and mechanism drivers. Official OpenStack documentation describes ML2 as a plug-in with components for network types and mechanisms, not as a service plugin .

Service plugins in Neutron are different. They add higher-level networking services beyond basic Layer 2 connectivity. OpenStack deployment documentation shows optional service areas such as load balancing and virtual private network services, and Neutron’s router-related functionality is commonly associated with the L3 service plugin . These are examples of service plugins layered on top of the core networking plugin model.

So the key distinction is this: ML2 is the core plugin architecture , while L3, VPN, and load balancing belong to the service-plugin category. In Huawei Cloud Stack networking topic coverage, this separation between the core Neutron plugin and optional service plugins is also fundamental. Therefore, the option that is not a service plugin is B. ML2 Plugin .

The correct answer is C. Tenant application response time . Huawei’s comprehensive monitoring documentation states that service monitoring tests the health of the current application and locates application exceptions based on monitoring metrics such as response time and availability . That directly matches the scenario of monitoring tenant application response time .

The other options belong to different monitoring domains. Health status of the physical server power supply is hardware or infrastructure monitoring, not service monitoring. Virtual network congestion is a network-layer performance issue rather than an application service-monitoring scenario. Latency of the distributed tracing system is closer to tracing or APM platform internals than to the application service-monitoring scenario explicitly described in Huawei’s cited service-monitoring definition. Huawei’s wording focuses on the monitored application’s health, response time, and availability, not hardware power modules or tracing-platform latency.

Therefore, based on Huawei’s official description of comprehensive service monitoring , the scenario clearly covered is tenant application response time , making the verified answer C .

The correct answer is C. Unified hardware model. Huawei’s System Integration description states that it provides a unified access mode and drive development standard for connecting cloud platforms to ManageOne. Huawei’s cloud-service architecture materials also explicitly reference items such as Unified Authentication, which is part of the common-component layer used during login and service access.

Within Huawei Cloud Stack’s unified access and integration model, service-facing capabilities such as unified service catalog, unified authentication, and unified metering belong to the logical platform-access specification set. These are cloud-management and service-governance functions. By contrast, unified hardware model does not fit that category, because the “10 Unified Access Specifications” are about access, integration, management, and service consistency, not about forcing all infrastructure hardware into one model. Huawei Cloud Stack supports heterogeneous infrastructure and abstracts it through the platform rather than treating “unified hardware model” as an access specification. Therefore, the item that is not included is C.

========

The correct answer is C. Glance Store . OpenStack’s official Glance architecture documentation states that all image data operations are performed using the glance_store library, and that this library is responsible for interaction with external storage back ends and/or local file systems . The same documentation explains that glance_store provides a uniform interface to access backend stores, which is exactly the function described in the question.

The other options do not match this role. The REST API exposes image service operations to clients, but it does not directly serve as the backend storage interaction layer. The database stores metadata about images, while the actual image binary data is handled through the storage interface. “ Glance Domain Controller ” is not a standard Glance core component in official OpenStack architecture. In Huawei Cloud Stack and OpenStack-based image management, the distinction between image metadata management and image data storage interaction is important, and the storage-facing part is handled by Glance Store . Therefore, the fully verified answer is C .

OpenStack is widely recognized for its openness, flexibility, and scalability . Official OpenStack documentation describes OpenStack as an open-source cloud platform that allows organizations to integrate different technologies and build clouds with a high degree of flexibility. It also explicitly highlights horizontal scalability , meaning compute, storage, and network resources can be expanded as demand grows. In addition, OpenStack and related OpenInfra materials consistently emphasize openness as a defining characteristic of the platform.

By contrast, efficiency is certainly a benefit that cloud platforms may deliver, but it is not typically presented as one of the foundational core concepts of OpenStack in the same way as openness, flexibility, and scalability. Huawei-authored OpenStack content also discusses OpenStack in terms of openness and scalability, which aligns with the standard industry description rather than listing efficiency as a core concept. Therefore, among the options given, Efficiency is the one that is not considered a core concept of OpenStack.
