A company uses Huawei Cloud Stack to operate its services. For the purpose of security, match the following personnel with their minimum permissions.
정답:
* 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.
문제 3
In HUAWEI CLOUD Stack, the management of BMSs depends on the component Ironic , which manages physical servers throughout their lifecycle. (Fill in the blank.)
정답:
Ironic Explanation: 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 .
