Pass the Huawei HCIP-Cloud Computing H13-527_V5.0 Questions and answers with ExamsMirror

The correct answers are A and C. Huawei’s cloud-service monitoring documentation shows that administrators can view the cloud service topology and dependencies between the current cloud service and other cloud services. This is exactly the kind of capability enabled by a CMDB’s dynamic dependency model, and it clearly supports application deployment topology display, which corresponds to option C.

Dynamic dependency information is also highly relevant to root cause locating, because dependency graphs help O & M personnel trace failures from one service to dependent services and identify the likely upstream or downstream source of an issue. Huawei troubleshooting materials reference locating faults of dependent services, which aligns with option A.

By contrast, resource capacity planning is a capacity-management scenario rather than a dynamic-dependency scenario, and certificate replacement in batches is an operational maintenance task that does not primarily depend on CMDB dynamic dependencies. Therefore, the supported scenarios are A and C, making the verified answer A, C.

The statement is TRUE according to the official HOT specification. OpenStack Heat documentation shows the overall HOT structure and explains that heat_template_version identifies the YAML document as a HOT template of a specific version. This key is fundamental because it tells Heat which template format and feature set to validate.

The same HOT specification states that the resources section contains the declaration of the resources in the template and that this section with at least one resource should be defined in any HOT template , otherwise the template would not really do anything when instantiated. In other words, a valid HOT template intended to deploy a stack needs both the version declaration and a resource definition.

Other sections such as description, parameters, outputs, and conditions are documented as optional. That is why heat_template_version and resources stand out as the core required parts for normal HOT authoring. In Huawei Cloud Stack training contexts based on OpenStack Heat, these are treated as the mandatory structural elements of a HOT template. Therefore, the verified answer is A (TRUE) .

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 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 .

CCS API → Provide the service logic of CCS tagging

CCS Console → Provide administrators with visualized CCS tagging

CCS Client → Provide administrators with cloud service tagging using CCS command lines

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

This drag-and-drop match follows the normal architectural roles of Huawei Cloud Stack CCS components. The CCS API is the backend service interface, so it is responsible for the service logic of CCS tagging . In cloud platforms, APIs handle request processing, tag creation, tag query, and tag-management actions exposed to other components or clients. The CCS Console is the graphical management interface, so its role is to provide administrators with visualized CCS tagging . This means administrators can perform tag-related operations through a web-based UI rather than command lines. The CCS Client is the command-line access component, so it is used to provide administrators with cloud service tagging using CCS command lines .

This mapping is also consistent with standard Huawei Cloud Stack component design principles: API for backend logic , Console for visual management , and Client for CLI-based operations . In practical cloud O & M and resource governance, these three components complement each other by supporting programmatic integration, web-based administration, and command-line automation. Therefore, the verified matching is: CCS API → service logic , CCS Console → visualized tagging , and CCS Client → command-line tagging .

Horizon is OpenStack’s web-based dashboard, which means it provides a graphical user interface for managing cloud services such as compute, networking, identity, and storage. OpenStack’s Horizon project documentation describes Horizon as the canonical dashboard implementation and a web-based user interface for OpenStack services. Because of that, using command-line interfaces (CLIs) is separate from Horizon rather than a function performed inside Horizon itself. OpenStack documentation also treats the dashboard and the command-line clients as different ways to interact with the cloud.

The other options describe actions that are consistent with what Horizon is used for. OpenStack materials show that users can start and stop VM instances, and Horizon is commonly used to manage cloud resources including projects, images, and networking-related items such as tenant networks. Modern OpenStack deployments also expose dashboards or panels that surface operational details, including instance console logs or monitoring-related views depending on enabled services. Therefore, the only option that is not something you do using Horizon itself is A, because CLI management is performed outside the Horizon dashboard.

The correct answer is B. VM performance deteriorates. Huawei’s official Resource Audit Overview for HUAWEI CLOUD Stack explains that Service OM resource audit is designed for high-frequency exception types caused by unplanned system failures, such as host reboot, process restart, or backup recovery. Huawei explicitly states that resource audit is used when problems such as residual resources and unavailable resources occur after those events. This directly matches options C and D. The same audit section also covers scenarios like abnormal VM states, orphan VMs, fake VMs, and image or volume inconsistencies caused by restoration or failed processes.

By contrast, VM performance deterioration is a performance management or capacity tuning issue, not a resource-audit exception type. Huawei’s compute resource management materials discuss performance tuning separately, such as changing VM flavors or adjusting resources, which shows that performance degradation is not handled by the Service OM resource-audit function itself. Therefore, among the four options, the issue that cannot be handled by Service OM’s resource audit 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 .

Developers → Users can only log in to the ECS using VNC. They cannot change the ECS specifications.

O & M personnel → An ECS can be restarted, but the system or software version cannot be upgraded.

Financial personnel → Users can only view cost reports. They cannot perform operations on resources.

This matching follows the least-privilege principle used in HUAWEI CLOUD Stack permission design. Huawei documentation emphasizes separating user responsibilities and assigning permissions based on operational roles, so users receive only the minimum capabilities required for their work. Huawei also describes resource grouping and user-group-based authorization as a standard way to control who can apply for or manage resources.

Based on that model, financial personnel should have the narrowest access, limited to viewing cost reports without operating resources. Developers usually need access to instances for testing or development work, but under minimum-permission security they should not be allowed to alter infrastructure specifications, so VNC-only login without ECS specification changes is the best match. O & M personnel need more operational control than developers, such as basic restart capability, but under minimum permissions they still should not perform higher-risk actions like upgrading the system or software version unless explicitly authorized. This division reduces accidental changes, lowers operational risk, and aligns with Huawei Cloud Stack’s role-based access and tenant/resource governance approach.

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 .
