Which of the following statements are true about the features and functions of the FusionCompute virtualization suite?
Answer(s): A,B,C,D
Comprehensive and Detailed Explanation (HCIACloud Computing aligned):Huawei FusionCompute provides a comprehensive virtualization platform with advanced management and scheduling capabilities.A is true. FusionCompute supports dynamic resource adjustment, including CPU and memory scaling, helping applications adapt to workload changes.B is true. FusionCompute supports x86 and Arm architectures, multiple storage backends, and mainstream operating systems such as Linux and Windows, ensuring broad application compatibility.C is true. SLA policies allow administrators to define priorities for virtual machines, ensuring that critical applications receive sufficient resources.D is true. FusionCompute supports automatic VM migration (such as DRS-like features) based on predefined policies to balance workloads and optimize system performance.All listed statements correctly describe FusionCompute capabilities.
Which of the following statements are true about deploying Compute Node Agent (CNA) and Virtual Resource Management (VRM) in Huawei FusionCompute?
Answer(s): B,C,D
Comprehensive and Detailed Explanation (HCIACloud Computing aligned):In FusionCompute architecture, CNA and VRM have clearly defined deployment models.Option A is false. CNA is deployed only on physical servers (compute nodes). It is responsible for interacting directly with hardware resources and cannot run inside a VM.Option B is true. When VRM is deployed on physical servers, active and standby VRM nodes must be installed on separate physical servers to ensure high availability.Option C is true. When VRM is deployed on virtual machines, the active and standby VRM VMs must be placed on different hosts within the management cluster to avoid single points of failure.Option D is true. VRM supports deployment on either physical servers or virtual machines, providing flexible management options.Therefore, the correct answers are B, C, and D.
Hypervisor is the key to virtualizing compute resources. Which of the following is also called a hypervisor?
Answer(s): A
Comprehensive and Detailed Explanation (HCIACloud Computing aligned):In the HCIACloud Computing virtualization domain, the hypervisor is the core software layer responsible for abstracting and managing physical compute resources and enabling multiple virtual machines to run on a single physical host.A hypervisor is also commonly referred to as a Virtual Machine Monitor (VMM). The VMM directly manages CPU scheduling, memory allocation, and virtual device access for guest operating systems.The other options are not equivalent to a hypervisor:VRM (Virtual Resource Management) refers to centralized management components used in platforms like FusionCompute.VNM (Virtual Network Management) relates to virtual networking control.VPM (Virtual Power or Performance Management) is not a hypervisor concept in HCIA materials.Therefore, the correct answer is VMM.
Which of the following statements is false about a Virtual Image Management System (VIMS) file system?
Answer(s): C
Comprehensive and Detailed Explanation (HCIACloud Computing aligned):In Huawei FusionCompute, VIMS is a storage virtualization file system designed specifically forHuawei's virtualization platform.Option A is true. VIMS underpins advanced storage features such as thin provisioning, snapshots, and live storage migration, which are core functions in FusionCompute.Option B is true. VIMS supports multiple backend storage types, including FC SAN, IP SAN, and local disks, offering flexible deployment options.Option D is true. VIMS is a high-performance cluster file system optimized for virtualized environments and concurrent access.Option C is false. VIMS is not a universal industry-standard file system. It is a Huawei-specific storage virtualization file system, designed for FusionCompute and not broadly adopted across all vendors.Thus, the false statement is C.
Which of the following statements is false about CPU virtualization?
Answer(s): D
Comprehensive and Detailed Explanation (HCIACloud Computing aligned):CPU virtualization is a fundamental concept in HCIACloud Computing and includes multiple implementation methods.Option A is correct. CPU virtualization is commonly categorized into full virtualization, paravirtualization, and hardware-assisted virtualization.Option B is correct. Full virtualization allows guest operating systems to run without modification, which ensures high compatibility and portability across different platforms.Option C is correct in the HCIA context. Paravirtualization requires modifications to the guest OS kernel, which historically limited support primarily to open-source operating systems.Option D is false. Hardware-assisted virtualization explicitly requires CPU support, such as Intel VT-x or AMD-V. Without these features, hardware-assisted virtualization cannot function.Therefore, the false statement is D.
