Practice Free H13-527_V5.0 HCIP-Cloud Computing V5.0 Exam Questions Answers With Explanation

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 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 best verified answer is A, B, and C. Huawei’s Managing Network Resources documentation states that on Service OM, administrators can view the number of created physical networks and virtual networks, which supports option C. The same Huawei material also says administrators can collect information for handling VM network faults, and related VPC/API guidance shows Service OM visibility into ports, including VM NIC-related ports, which supports A.

Huawei documentation for Direct Connect further shows that administrators can create Direct Connect access points on Service OM before tenants can use Direct Connect. In training-style wording, this aligns with the idea of creating private line access points, so B is also correct.

Option D is the one that does not fit as a standard Service OM network resource management action in the same way. Huawei documentation emphasizes viewing physical network information and managing related network resources, but creation or low-level configuration of physical networks is generally handled through platform network configuration workflows rather than as a routine Service OM tenant/resource function. Therefore, the correct set is A, B, C.

========

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 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 D. Changes of the VM CPU usage over time . OpenStack documentation describes Gnocchi as a time-series storage and resource indexing service . In the Telemetry pipeline documentation, OpenStack explicitly states that when the Gnocchi publisher is enabled, measurement and resource information is pushed to Gnocchi for time-series optimized storage . That makes Gnocchi the right component for storing metrics that change continuously over time, such as CPU utilization, memory usage, disk I/O, and similar performance measurements.

By contrast, the other options describe events, configuration changes, or audit-style records , which are not the primary use case for Gnocchi. OpenStack’s telemetry retrieval guidance recommends storing metric data in Gnocchi, while event data should be stored in an event-oriented service such as Panko. This clearly separates time-series metrics from event or log records.

Therefore, in Huawei Cloud Stack and OpenStack telemetry scenarios, Gnocchi is best suited for historical metric trends , making VM CPU usage over time the most appropriate choice.

The best verified answer is A, B, and D . Huawei networking documentation shows that Internet access troubleshooting for cloud resources commonly involves checking whether an EIP is bound or whether a NAT gateway is configured , which supports A . Huawei guidance also explicitly refers to selecting or checking an appropriate EIP bandwidth , which supports D as a normal troubleshooting item.

Huawei documentation also shows that network ACL rules are part of VPC access control and can affect connectivity. Because network ACLs are stateless and traffic validation depends on rule direction, checking ACL rules is a reasonable O & M troubleshooting operation. In your option wording, inbound rules are still part of that validation scope, so B is acceptable.

By contrast, checking route configurations on core switches is not the standard first-line troubleshooting action for tenant-side VPC Internet access in Huawei Cloud Stack service O & M. The cloud service boundary is usually diagnosed first through NAT, ACL, and EIP-related configuration. Therefore, the verified answer is A, B, and D .

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 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) .

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 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 .

The correct answer is B. BMS . For a typical web application architecture on HUAWEI CLOUD Stack, ECS provides the compute instances, IMS provides reusable images for quick deployment, AS enables elastic scale-out and scale-in based on demand, and ELB distributes traffic and improves availability. Huawei’s ECS and IMS documentation explicitly notes that ECS images can be used with Auto Scaling for dynamic expansion to meet peak demand, which directly supports quick deployment and elasticity.

BMS is a dedicated bare-metal service intended for scenarios needing direct physical hardware access, stronger isolation, or reduced virtualization overhead. It is useful for special workloads, but it is not required for the classic goals listed in the question, especially high cost-effectiveness and fast elastic web scaling. Those goals are more naturally achieved with ECS-based architectures plus ELB and AS. Huawei’s BMS positioning emphasizes physical-server management and performance advantages, not being a necessary part of a standard web application elasticity stack. Therefore, among the listed services, the one that is not required is BMS , making B the verified answer.

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) .
