Free Practice Questions for Huawei H13-527_V5.0 Exam

The correct fill-in answer is VPN gateway . In Huawei Cloud Stack networking, an EIP can be associated not only with an individual ECS, but also with shared-access components that serve multiple backend resources. Huawei documentation clearly states that when multiple cloud servers in a subnet need outbound Internet access, they can use a NAT gateway and share an EIP . Huawei’s ELB documentation also reflects the model where a load balancer exposes services externally on behalf of multiple backend ECSs.

In the same family of network services, a VPN gateway is another gateway-type object that uses public-facing connectivity to provide secure access for multiple private-side resources. That is why the exam sentence groups it with load balancer and NAT gateway . The logic is that these service gateways allow multiple ECSs or private resources to make use of a single public-facing IP resource instead of requiring one EIP per server. Huawei’s VPN service documentation also shows VPN as the gateway-based service for secure site-to-cloud communication.

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 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 .

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 fill-in answer is Ironic . Huawei’s official HUAWEI CLOUD Stack documentation clearly states that Ironic provides BMS management services by working with components such as Nova and Neutron . Huawei’s BMS usage guide also explicitly refers to BMS lifecycle management operations , including actions such as starting, stopping, forcibly stopping, and other lifecycle tasks. This confirms that Ironic is the component responsible for managing physical servers through their lifecycle in a Huawei Cloud Stack environment.

This is consistent with standard OpenStack architecture as well, where Ironic is the OpenStack Bare Metal service used to provision and manage physical machines similarly to how Nova manages virtual machines. In Huawei Cloud Stack, BMS is not handled as a simple ECS variant; instead, it relies on Ironic for provisioning, state transitions, and lifecycle orchestration of dedicated hardware resources.

Therefore, after correcting the sentence, the blank should be filled with Ironic , and the fully verified answer is Ironic .

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 A (TRUE) . Huawei Cloud Stack compute resource management documentation explicitly describes the behavior of soft-affinity , which is the practical equivalent of weak affinity in scheduling policy terms. Huawei states that if host resources are sufficient, VMs in the same soft-affinity group will be scheduled to the same host . It further states that if resources are insufficient or the current host is faulty, the VMs can be scheduled to different hosts . This matches the wording of the question almost exactly.

Huawei ECS group documentation also explains that an ECS group can be configured with affinity, anti-affinity, weak affinity, or weak anti-affinity policies, which confirms that weak affinity is an officially recognized scheduling policy in Huawei Cloud Stack. The “weak” part means the scheduler prefers a placement rule but is allowed to violate it when necessary to ensure successful deployment or continuity.

Therefore, the statement accurately reflects Huawei’s documented scheduling behavior: under normal conditions, VMs tend to be placed together, but if resources are inadequate, the rule may be broken. So the verified answer is TRUE .

The correct answer is B (FALSE). Huawei documentation confirms that a dummy external network exists and may appear as an option when creating services such as VPC-related resources. Huawei’s Elastic IP and related network-service guidance gives examples such as selecting the dummy external network in one group and then selecting an actual Internet external network in another group for service use. This shows that the dummy external network is mainly a default placeholder or structural network object, not the real tenant-bound network required for service traffic.

Because of that, the second part of the statement is inaccurate. The proper requirement is not simply to “bind the dummy external network to tenants” so VPCs can be created properly. Instead, tenants and services need the correct actual external network resources and related mappings or selections. The Huawei examples make it clear that the dummy external network is not the operational external network used for normal connectivity. Therefore, although the first part about default creation is consistent with Huawei practice, the conclusion about binding it to tenants is not correct. For that reason, the full statement is FALSE.

========

The correct answer is B (FALSE) . Huawei documentation confirms that FusionCare is a deployed component used for inspection and troubleshooting , but the statement’s deployment location is not reliably correct as written. In Huawei Cloud Stack maintenance and troubleshooting materials, Huawei explicitly references logging in to FusionCare separately and also notes cases where administrators must obtain the IP address of the node where FusionCare is deployed , which shows it is treated as a specific deployable node/service rather than a fixed default identity tied universally to PUB-SRV-01 .

More importantly, Huawei documentation for certificate replacement states that administrators may need the IP address of the PUB-SRV03 node where FusionCare is deployed , which directly contradicts the claim that FusionCare runs on PUB-SRV-01 by default. Huawei O & M rollback documents also mention checking whether FusionCare is deployed in each secondary region , indicating that its deployment is not always a single fixed-node default in the simplistic way the statement suggests.

So, although FusionCare is indeed part of Huawei Cloud Stack O & M, the statement is inaccurate because the node/location claim is not universally true. Therefore, the verified answer is FALSE .
