Free Huawei H13-527_V5.0 Practice Exam with Questions & Answers | Set: 2

The correct answer is C. show . Official OpenStack command-line documentation explicitly lists the command openstack server show < server > and explains that it is used to show server details . The same documentation states that the < server > argument represents the server name or ID , which matches the wording in your question exactly.

The other options are not correct in this context. openstack server list displays a list of servers rather than the details of one specific instance. query and conf are not valid standard subcommands for this OpenStack server-detail operation. Since HUAWEI CLOUD Stack operations in this area follow OpenStack command syntax for instance inspection and lifecycle management, the proper command for viewing one instance’s details is openstack server show < server > .

Therefore, after correcting the sentence format, the blank should be filled with show , and the full verified command is openstack server show < server > . That makes the correct answer 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 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 .

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 statement is TRUE . Huawei’s official HUAWEI CLOUD Stack storage-resource documentation explicitly states that a storage backend can contain one or more storage pools of the same cloud block storage system , and it also clearly states that a storage backend only belongs to one AZ . This matches the wording of the question almost exactly. ( )

Huawei’s more recent resource-provisioning documentation repeats the same architecture principles: a storage pool belongs to only one storage backend , a disk type belongs to only one AZ , and a storage backend device can contain one or more storage pools . This design helps keep storage planning and fault-domain boundaries clear in multi-AZ cloud deployments. ( )

In practical HUAWEI CLOUD Stack operation, this means one backend can aggregate multiple pools from the same storage system for service use, but the backend itself is still scoped to a single availability zone for resource isolation and service planning. Therefore, the verified answer is A (TRUE) . ( )

========

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 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 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) .
