Through the full virtualization technology, multiple operating systems can run on the same server, and the virtual machine thinks that it is running on a dedicated server.
Correct Answer: A
Question 27
The KVM virtualization architecture includes modules, QEMU and Libvirt. Which of the following descriptions about these modules is incorrect?
Correct Answer: A
Question 28
FusionCompute consists of two parts: CNA and VRM. Which of the following is not a function of CNA?
Correct Answer: C
Question 29
Which of the following statements are true about the differences between OpenStack and FusionCompute?
Correct Answer: A,B,C,D
As covered in the "Cloud Computing Trends" and "Huawei Cloud Solutions" modules of the HCIA curriculum, OpenStack and FusionCompute occupy different layers of the cloud stack. Statement A is correct: OpenStack is a global open-source project maintained by a community, whereas FusionCompute is Huawei's proprietary commercial virtualization platform (hypervisor).4 Statement B captures a fundamental technical difference. OpenStack is anorchestratoror "Cloud OS"; it lacks an internal hypervisor and must rely on external technologies (like KVM, Xen, or FusionCompute itself) to perform the actual virtualization. In contrast, FusionCompute is a standalonevirtualization suitethat includes the CNA (hypervisor) and VRM (management), allowing it to directly pool and manage physical hardware resources. Statement C highlights the broader scope of OpenStack, which is designed to manage heterogeneous resources, including Bare Metal (Ironic) and Containers (Zun/Magnum). FusionCompute is a specialized tool primarily focused on Virtual Machines (VMs). Finally, Statement D refers to theMulti-tenancymodel. OpenStack was built for public and large private clouds, using "Projects" and "Tenants" to strictly isolate resources and billing between different organizations. FusionCompute is a lower-level resource manager that focuses on "Clusters" and "Resource Pools" rather than the complex tenant-based isolation logic found in high-level cloud platforms. In the Huawei ecosystem, FusionCompute often serves as the "Computing" component underneath a largerHuawei Cloud Stackor OpenStack-based solution, illustrating how these two technologies complement each other in a modern data center.
Question 30
In FusionCompute, CPU and memory resources support hot addition, but storage resources and network resources do not support adding.
