Free and Premium Huawei H13-527_V5.0 Dumps Questions Answers

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 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 correct answer is C. Format a physical storage device . Official OpenStack Cinder documentation shows that the Block Storage API supports operations such as attaching a volume to an instance , creating snapshots , and resizing/extending volumes . The Cinder CLI and API references explicitly list volume attachment, snapshot-related operations, and extend or resize functions as supported capabilities.

By contrast, formatting a physical storage device is not a standard function of the Cinder API. Cinder provides a cloud block storage service layer and interacts with backend storage through drivers, but low-level formatting of physical disks is a backend storage administration task rather than a tenant-facing or standard Cinder API operation. The Cinder service abstracts backend complexity and exposes logical operations on volumes, not raw hardware provisioning steps such as formatting a physical device.

In Huawei Cloud Stack and OpenStack-based environments, this distinction is essential: cloud users and administrators manage logical block storage resources through Cinder, while backend storage initialization and device formatting are handled outside normal Cinder-API operations. Therefore, the verified answer is C .

Domain → A top-level container that is globally unique in Keystone

Role → Permission set

Endpoint → External access address of a single service

Group → User set

These matches are consistent with official OpenStack Keystone identity concepts. OpenStack documentation defines a group as a collection of users , so “user set” is the correct description for Group . It also explains that a role is used in Keystone’s RBAC model to represent a set of permissions that can be assigned to users or groups, so Role → Permission set is correct.

For Endpoint , OpenStack service configuration documentation describes endpoints as the network-accessible API addresses used to access a service, which matches external access address of a single service .

For Domain , Keystone identity documentation explains that domains are top-level containers used to organize projects, users, and groups. In practice, a domain is a globally unique administrative boundary in Keystone, which matches the description a top-level container that is globally unique in Keystone .

So the final verified mapping is: Domain → top-level container , Role → permission set , Endpoint → service access address , and Group → user set .

The correct answers are B, C, and D. Huawei’s official resource-analysis documentation states that bottleneck resources can be identified and analyzed globally and by VDC, resource pool, and application. This directly matches options B, C, and D in your question.

Although Huawei also has resource-pool analysis views that can monitor resources from multiple dimensions such as region, resource pool, and AZ, the specific wording for bottleneck analysis in the cited Huawei documentation highlights application, VDC, and resource pool as the relevant factors used for bottleneck identification and analysis. That is why AZs should not be selected for this particular question.

So, after correcting the sentence structure, the supported dimensions for bottleneck-related analysis by O & M administrators are applications, VDCs, and resource pools. Therefore, the verified answer is B, C, D.

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

The correct answer is B. AutoOps . In HUAWEI CLOUD Stack, AutoOps is the automation platform used for standardized O & M task execution. Its core value is that it can take individual atomic operations and organize them into automated workflows, allowing repeated maintenance and troubleshooting procedures to be executed in a consistent, efficient, and less error-prone manner. This makes it highly suitable for routine operational tasks, fault handling, and platform maintenance scenarios where manual execution would be slower and more risky.

The other options have different roles. CMDB is mainly used for configuration and dependency information management. FusionCare is more focused on inspection, health check, and troubleshooting support. CloudNetDebug is designed for network fault diagnosis, especially for virtual network path troubleshooting. None of these primarily serve as the orchestration and automation engine for O & M workflows.

Therefore, when the requirement is to automate standardized operations and execute orchestration-based maintenance tasks in HUAWEI CLOUD Stack, the best answer is AutoOps , so the correct option is B .

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 .

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. 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 correct answer is B. Managing the services or resources of branches across regions . In HUAWEI CLOUD Stack, resource sets are primarily used as an internal organizational and authorization tool within a tenant or VDC . They are well suited for grouping resources by department , project , or environment , such as production versus test resources. This means options A , C , and D are all typical and appropriate use cases because they involve structuring and controlling resources inside the same logical management domain. ( )

By contrast, managing services or resources of branches across regions is broader than the normal scope of a resource set. Cross-region branch management usually involves higher-level multi-region organizational constructs, regional administration, or broader tenant/VDC design rather than simply creating a resource set. Resource sets help refine governance inside an established tenant structure; they are not the main mechanism for organizing geographically distributed branch operations across regions.

So after correcting the wording, the scenario that is not suitable for resource sets is B , because it describes a cross-region management requirement that typically belongs to a higher-level cloud planning and governance model rather than a resource-set grouping function. Therefore, the verified answer is B .

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 fill-in answer is FTP. Huawei documentation for image registration on Service OM shows that images can be uploaded using different modes, including local upload, FTP, and NFS. The guidance indicates that for larger image files, administrators should use a network-based upload mode rather than simple local browser upload. In the Huawei document snippet, the upload options explicitly include NFS, and the paired option used in this context is FTP, which matches the exam sentence structure: “select ____ or NFS.”

This makes sense operationally in HUAWEI CLOUD Stack because large image files are more reliably transferred through shared file or server-based methods, especially in enterprise O & M scenarios. Local browser-based uploads are less suitable for very large images due to session stability, browser limits, and transfer reliability. Using FTP or NFS improves image registration efficiency and reduces the chance of interrupted uploads during image onboarding. Therefore, after correcting the sentence, the blank should be filled with FTP.

========

The correct answer is D. Resource pool and basic cloud service management . Huawei’s official License Guide includes a dedicated section called “Resource Pool & Basic Cloud Services” and explicitly instructs administrators to enter Service OM to perform management actions there. This directly ties Service OM to the management plane for resource pools and basic cloud services , rather than positioning it primarily as a hardware-monitoring tool or a deployment platform.

Huawei Cloud Stack O & M materials also show Service OM being used for operational management tasks such as viewing VMs, host groups, cloud services, and system resource status. In contrast, deployment and upgrade are associated with dedicated installation and upgrade tools, not Service OM as the main function. Similarly, centralized monitoring across products is broader than Service OM’s core purpose and is covered by other monitoring and O & M capabilities in the Huawei Cloud Stack architecture.

Therefore, among the available choices, the description that best matches Huawei’s official positioning of Service OM is resource pool and basic cloud service management . That makes D the most accurate and fully verified answer.

========

The statement is TRUE. Huawei Cloud Stack separates management responsibilities between operation administrators and VDC administrators. Huawei’s service-management documentation shows that operation administrators work at the platform-wide level and can publish cloud services and associate them with approval processes, which reflects their broader administrative scope. By contrast, VDC administrators work within the boundary of their own VDC and manage service usage and permissions inside that tenant-like scope. This architecture strongly supports the rule that both roles can participate in approval-process customization, but the visibility scope is different.

In practice, this means an approval process created by an operation administrator can be used as a global process across the platform, while a process created by a VDC administrator is limited to the VDC context rather than being exposed to all tenants or all service domains. This aligns with Huawei Cloud Stack’s layered governance model, where global service governance belongs to operation administrators and tenant-level governance belongs to VDC administrators. Therefore, the correct answer is A (TRUE).

========

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 .

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 statement is FALSE . Official OpenStack documentation clearly distinguishes pause from suspend . When a server is paused , OpenStack states that the state of the VM is stored in RAM , and the instance continues in a frozen state. This means memory is not written to disk during a pause operation. Because RAM is still occupied, a paused VM does not reduce resource usage to a minimal level in the way the question suggests.

By contrast, when a server is suspended , OpenStack documentation says that its state is stored on disk , all memory is written to disk , and the server is stopped. This is the action that is conceptually similar to hibernation. The distinction is important in OpenStack and Huawei Cloud Stack operations because pause is mainly used for temporary freezing of execution, while suspend is used when preserving state on disk is required. Therefore, the statement in the question incorrectly describes suspend , not pause . For that reason, the correct answer is B (FALSE) .

The correct answer is PKI. In OpenStack Keystone, PKI (Public Key Infrastructure) tokens are cryptographically signed and specifically rely on a public/private key pair. Official OpenStack Keystone documentation states that PKI tokens are signed documents and that the Identity service uses public/private key pairs and certificates to create and validate them. It also explains that PKI and PKIZ tokens can be verified offline using Keystone’s public signing key, which directly matches the wording in the question about signing and verification.

By contrast, UUID tokens are simple persisted identifiers and do not inherently depend on public/private key signing. Fernet tokens are also a Keystone token format, but they are based on symmetric cryptography and shared key repositories rather than a public/private key pair. OpenStack documentation explicitly distinguishes Fernet and UUID from the deprecated PKI token mechanism. Therefore, among the listed options, the authentication method that uses a pair of private and public keys is clearly PKI. This aligns with standard OpenStack identity-service architecture and is consistent with Huawei Cloud Stack training topics that build on Keystone authentication concepts.
