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 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) . ( )

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 .

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 .

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 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 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.

========

AS group → A set of instances with the same application scenario

AS policy → Specify the conditions for triggering an AS action

AS configuration → Define the specifications of the instance to be added

AS action → Its purpose is to keep the number of instances in the application system the same as expected

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

This matching is consistent with Huawei’s official Auto Scaling concept definitions. Huawei states that an AS group consists of a collection of instances that apply to the same application scenario , so that description belongs to AS group . Huawei also explains that an AS policy specifies the conditions for triggering a scaling action , which makes the second match straightforward.

Huawei’s Auto Scaling documentation further distinguishes AS configuration from policy and action. The configuration defines the template or specifications for the instances that will be added during scaling, so define the specifications of the instance to be added correctly matches AS configuration . Finally, Huawei defines a scaling action as adding or removing ECS instances from an AS group, and states that its purpose is to keep the number of instances in the application system at the expected level. That directly matches the final description.

So the verified drag-and-drop mapping is: group = instance set , policy = trigger condition , configuration = instance specification , and action = maintain expected instance count .

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.
