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 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.
