H13-527_V5.0 HCIP-Cloud Computing V5.0 Questions and 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 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) .

The correct answers are B and D . Huawei’s VPN documentation describes VPN as a way to establish an encrypted communication channel between a VPC and an external network such as a local data center . This makes VPN suitable for a temporary or cost-sensitive connection between a local IDC and a VPC, so B is correct.

Huawei materials about hybrid-cloud and enterprise connectivity also describe VPN as a way for enterprise sites or private-cloud resources to access cloud services securely. That aligns well with a branch accessing cloud resources on the headquarters cloud , making D a valid VPN scenario.

Option C is not appropriate because Huawei typically positions dedicated/private line connectivity rather than Internet-based VPN for scenarios with high network-latency requirements , such as financial transaction systems. Option A is also not the standard answer in Huawei Cloud Stack service design, because cross-region VPC interconnection is typically handled with other networking constructs rather than ordinary site-to-cloud VPN as the primary recommended model. Therefore, the best verified answer is B, D .

========

The best verified answer is D. Workspace . Huawei’s official health-check documentation for FusionCare shows that FusionCare supports unified health checks for multiple Huawei Cloud Stack components and services. The published health-check item lists explicitly include Service OM , eSight , and CCE and SWR , which confirms that those services are within FusionCare’s supported inspection scope.

By contrast, the Huawei monitoring materials mention Workspace Overview under broader monitoring capabilities, not under the FusionCare-supported health-check list shown in the cited documents. In other words, Workspace appears in Huawei’s overall monitoring ecosystem, but it is not evidenced in the cited FusionCare support list the way Service OM, eSight, and CCE are. That makes Workspace the option that cannot be checked using FusionCare in this question set.

So based on Huawei’s documented FusionCare-supported inspection items, A , B , and C are covered, while D is not shown as a FusionCare check target. 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 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. 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 D . Huawei’s official HUAWEI CLOUD Stack NAT Gateway documentation explains that DNAT is used to map the private IP address and port of a cloud server in a VPC to a public IP address and port by binding an EIP. In practical terms, DNAT allows requests that arrive at a public IP address to be forwarded to the private IP address of a server inside the cloud network. That matches option D exactly.

Option A describes SNAT , not DNAT. Huawei explicitly states that SNAT translates a private IP address into an extranet/public IP address so cloud servers can access the Internet. Option B is also related to SNAT behavior, because Huawei notes that multiple cloud servers in a VPC can share an EIP for outbound Internet access through SNAT. Option C describes a filtering or firewall-style function rather than NAT translation.

Therefore, in Huawei Cloud Stack networking, DNAT is specifically used for inbound mapping from public addresses to private cloud-server addresses , so the verified answer is D .

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.

========

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 .

Horizon is the web-based dashboard for OpenStack, designed to provide a consistent graphical interface for managing cloud resources. In practice, Horizon focuses on presenting a consistent view of services to users and administrators, and OpenStack components commonly maintain API backward compatibility to support upgrades and continued interoperability. OpenStack documentation also shows that Horizon can be used in larger and multi-region environments, which supports the idea that scalability is relevant to its operational value.

However, API eventual consistency is not a Horizon value proposition. “Eventual consistency” is a concept found in distributed storage systems such as OpenStack Swift/Object Storage, where updates may take time to become visible everywhere. OpenStack documentation explicitly uses this term in the context of Object Storage behavior, not Horizon dashboard design. Because Horizon is a management dashboard rather than a distributed storage consistency model, API eventual consistency does not belong as one of its core value propositions. Therefore, the correct answer is A . This is the best-supported conclusion from official OpenStack documentation and aligns with Huawei Cloud training-style OpenStack topic coverage.

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 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 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 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 .
