Which of the following is not a prerequisite for deleting a FusionCompute security group?
Correct Answer: D
Question 42
In Huawei FusionCompute, a VM running Linux is created. In this scenario, which of the following does the guest OS run in?
Correct Answer: C
(Note: The original question contained a typo. As requested, "host OS" has been corrected to "guest OS" because Linux, in this scenario, is the Guest operating system.) In the official Huawei HCIA-Cloud Computing curriculum, the architecture of a virtualized system is divided into the Host Machine and the Guest Machine. TheHost Machineis the physical server (hardware) and the virtualization software (CNA in FusionCompute). TheGuest Machineis the Virtual Machine (VM) created by the hypervisor. According to the training materials, theGuest OSis the operating system that is installed and executed within the virtualized environment of a VM.13 Therefore, if a VM running Linux is created, the Linux operating system is the Guest OS, and it runs specifically inside theLinux VM. The VM acts as a logical container that provides the Linux OS with virtualized CPU, memory, storage, and network resources.14From the perspective of the Linux OS, it believes it is running on a dedicated physical server, but in reality, it is encapsulated within the VM boundary provided by the CNA. The other components mentioned have different roles:CNA (Computing Node Agent)is the "host" software that manages the hardware and hosts the VM, but the Linux OS does not run "in" the CNA directly; it runs in the VM managed by the CNA.VRM (Virtual Resource Management)is the management platform used by administrators to create and configure the VM.VNA (Virtual Node Agent)is a process within the CNA that handles management commands from the VRM. In the Huawei certification logic, it is crucial to distinguish between the "Container" (the VM) and the "Occupant" (the Guest OS). The Guest OS is always tied to the VM environment, which ensures logical isolation and mobility across the cloud infrastructure.
Question 43
SSD is a kind of disk that is commonly used now. Which of the following characteristics does it have? (Multiple choice)
Correct Answer: A,C
Question 44
Horizontal expansion means that when the business volume continues to grow, it is not necessary to upgrade the server specifications, but only need to increase the number of servers to meet the demand.
Correct Answer: B
Question 45
FusionCompute supports the following memory overcommitment technologies: memory sharing, memory swapping, and memory ballooning. After host memory overcommitment is enabled in cluster resource control, one of the preceding memory overcommitment technologies needs to be selected.
Correct Answer: A
FusionCompute supportsmemory overcommitmentto improve overall memory utilization in virtualized environments. The supported technologies include: * Memory sharing * Memory ballooning * Memory swapping According to HCIA-Cloud Computing materials, after enabling memory overcommitment incluster resource control, administrators mustselect at least one memory overcommitment mechanismto take effect. Therefore, the statement correctly describes FusionCompute behavior and isTRUE.
