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

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) .

Data analysis platform → Eliminate data silos and unify metric models

Configuration management platform (CMDB) → Store and manage a wide variety of information about devices and systems in the enterprise IT architecture

AutoOps automation platform → Atomic operations can be orchestrated and then be executed

Agent and driver interconnection → The purpose is to implement full data access

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

This matching follows the normal functional roles of Huawei Cloud Stack O & M platforms. The data analysis platform is used to integrate monitoring and operational data from different domains, so its purpose is to eliminate data silos and unify metric models . The CMDB is the configuration management database, whose core role is to store and manage configuration and relationship information about devices, systems, and services across the enterprise IT architecture.

The AutoOps automation platform is designed for automated O & M execution. In Huawei Cloud Stack operations, this includes arranging standardized or atomic O & M tasks into executable workflows, so the description atomic operations can be orchestrated and then be executed correctly matches AutoOps. The agent and driver interconnection layer is the connectivity and collection mechanism used to connect tools, devices, and services so that data can be gathered comprehensively. Therefore, its purpose is to implement full data access .

So the final verified mapping is: data analysis platform = unified metrics , CMDB = configuration information management , AutoOps = orchestration and execution of atomic operations , and agent/driver interconnection = full data access .

This question is best treated as a multiple-correct-answer item, because official OpenStack documentation shows that Nova-Scheduler and Placement are both directly involved in the scheduling workflow. The Nova scheduling reference explains that the scheduler receives a request specification and then sends the requirements to Placement , which determines the resource providers capable of satisfying the request. Placement returns candidate resource information, and Nova-Scheduler performs filtering, weighing, and final host selection.

OpenStack documentation also notes that the nova-scheduler and placement services are responsible for tracking resources and deciding which compute node instances should be on . That makes A and D the directly scheduling-related components. While Nova-Conductor and Nova-API participate in the broader instance build flow by receiving requests and coordinating actions, they are not the core components that actually perform the scheduling decision itself.

So, for strict technical accuracy based on official OpenStack architecture, the verified answer is A and D . If your exam system forces only one option, then A (Nova-Scheduler) is the closest single best answer, but the documentation supports A and D together.

The correct answer is B (FALSE) . Huawei documentation supports the first part of the statement: Combined API is described as providing the service backend for services such as ECS, BMS, IMS, and EVS , and Huawei usage materials show console requests being forwarded through the UI to Combined API for backend processing. That means it does function as a backend service layer between the console and underlying cloud services.

However, the statement becomes incorrect when it says Combined API must be deployed in the Global zone . Huawei architecture documentation explains that Huawei Cloud Stack includes both a global zone and regional deployment structure , and not all components belong to the global zone. Huawei snippets describing global-region deployment list typical global-zone components such as ManageOne and the cloud service console , while Combined API is described separately as a service backend in the broader architecture of the region/global deployment model. This supports the conclusion that Combined API is not simply a mandatory global-zone-only component .

So the backend-function part is true, but the deployment claim is not. Therefore, the overall statement is FALSE .

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 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 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.
