This statement isincorrectbased on HCIA–Cloud Computing virtualization concepts.

First,KVM is not a pure paravirtualization technology. It is ahardware-assisted full virtualizationsolution that relies on CPU virtualization extensions. While KVM can use paravirtualized drivers (such as Virtio) to improve performance, its core architecture is hardware-assisted virtualization.

Second, KVM supportsdevice I/O virtualization. Using technologies such asVirtio, KVM provides efficient virtual network and storage devices. This allows virtual machines to achieve near-native I/O performance, which is a key feature emphasized in HCIA training.

Because the statement incorrectly classifies KVM and wrongly claims that it cannot virtualize device I/O, the correct answer isFALSE.

The HCIA–Cloud Computing syllabus clearly defines the basic terminology used in virtualization.

OptionAis correct. Aguest OSrefers to the operating system installed and running inside a virtual machine.

OptionBis correct. Aguest machineis another term for a virtual machine (VM).

OptionCis correct. Ahost machinetypically refers to thephysical serverthat provides hardware resources for virtualization.

OptionDis false. Ahost OS is not the virtualization software layer. The virtualization layer is thehypervisor(such as KVM, Xen, or FusionCompute). In some architectures, the host OS and hypervisor may coexist, but they arenot the same concept.

Therefore, the false statement isD.

According to the Huawei HCIA-Cloud Computing curriculum, specifically the "FusionAccess Planning and Deployment" section, the statement is TRUE. When an enterprise scales its desktop cloud across multiple regions or deploys separate FusionAccess environments (each with its own ITA/HDC/DB set), there is often a requirement to share a single license pool to optimize costs and management.

In a standard small-scale deployment, the License component is typically co-deployed with theITA (IT Adapter). However, if multiple independent FusionAccess systems (different clusters or management sets) need to draw from the same license file, the License component must be "de-coupled" from any specific ITA anddeployed independentlyas a standalone service. This standalone License Server acts as a centralized repository that tracks the total number of permitted desktop users or VMs. Each FusionAccess system is then configured to point to this central server's IP address.

This independent deployment model ensures that license seats are not "trapped" in one specific system. For example, if System A has 500 licenses but only 200 active users, and System B is at its limit, a centralized license server allows System B to utilize the excess capacity. This flexibility is a core architectural principle in Huawei’s large-scale VDI solutions. During deployment planning, administrators must decide whether to use a local license (co-deployed) or a centralized license (independent). For multi-system environments, the independent deployment is the official Huawei recommendation to ensure proper license reconciliation and to prevent "over-use" or "under-use" of purchased ICT assets across the enterprise.

====================

In the official Huawei HCIA-Cloud Computing curriculum, specifically the "Virtualization Basics" module, the characteristics of virtualized hardware are clearly defined. Statement D is FALSE because a Virtual Machine (VM) is not limited to a single virtual network interface card (vNIC). In fact, for many enterprise scenarios, a VM must have multiple vNICs. For example, a VM acting as a software firewall or a multi-homed server would require separate vNICs to connect to different logical networks (such as a Management network, a Service network, and a Backup network). Huawei FusionCompute supports the addition of multiple vNICs to a single VM, each capable of being assigned to a different port group or VLAN.

The other statements are correct based on Huawei’s technical standards. Statement A is true; every vNIC is assigned a globally uniqueMAC address(usually from a prefix reserved for Huawei virtualization) to ensure that Layer 2 switching functions correctly within the DVS. Statement B is true; just like a physical machine, each vNIC can be assigned a uniqueIP addressthrough static configuration or DHCP to allow for Layer 3 communication. Statement C is also accurate; from the perspective of the Guest Operating System, the vNIC behaves exactly like a physical PCI-E network card. It has a driver, it can be configured with MTU settings, and it can transmit and receive frames. The hypervisor (CNA) is responsible for intercepting the data from this "logical" NIC and forwarding it through the physical NICs of the host server. This transparent emulation is what allows standard operating systems and applications to run in the cloud without modification.

====================

In the official Huawei HCIA-Cloud Computing curriculum, specifically in the module "Huawei Virtualization Platform Management and Usage," the process for connecting hosts to storage is strictly defined. For storage types that rely on an Ethernet network (IP-based storage), such as IP SAN (iSCSI), NAS (NFS), and Huawei Distributed Block Storage (FusionStorage), the system requires the configuration of "Storage Ports" on each host. A storage port is a logical interface created on a physical NIC or a bond of NICs on a CNA (Computing Node Agent) node.

The reason this step is mandatory is that these storage protocols require an IP address to establish a session between the host (Initiator) and the storage device (Target). Without adding a storage port and assigning it a valid IP address within the storage network's segment, the host cannot communicate with the storage controllers. For IP SAN, this port is used to discover LUNs; for NAS, it is used to mount shared folders; and for Distributed Block Storage, it is used by the VNA (Virtual Node Agent) to communicate with the storage pool.

In contrast, forFC SANstorage, "storage ports" in the IP sense are not required because the Fibre Channel protocol uses World Wide Names (WWNs) on the Host Bus Adapters (HBAs) for identification. The Huawei documentation emphasizes that the storage network (Storage Plane) should be logically or physically isolated from the management and service planes to ensure high performance and security. Therefore, configuring storage ports with dedicated IPs is a prerequisite for creating a datastore on any IP-based storage backend in FusionCompute.

====================

According to the HCIA–Cloud Computing virtualization domain,KVM (Kernel-based Virtual Machine)andXenare both examples ofhardware-assisted virtualizationtechnologies.

Hardware-assisted virtualization relies on CPU extensions such asIntel VT-xandAMD-Vto improve virtualization performance and isolation. Both KVM and Xen leverage these CPU features.

KVMis implemented as akernel modulewithin the Linux operating system. Once loaded, the Linux kernel itself becomes a hypervisor, managing CPU and memory virtualization with hardware support.

Xenalso relies on hardware virtualization features and interacts closely with the operating system kernel, especially in full virtualization and hardware-assisted modes.

Because the statement correctly describes both thevirtualization typeand theimplementation approach, it aligns with HCIA documentation and isTRUE.

According to the Huawei HCIA-Cloud Computing curriculum and the FusionAccess Maintenance Guide, the statement is FALSE. While it is a recommended best practice to restart infrastructure virtual machines (VMs) approximately once every quarter to clear system cache, refresh memory resources, and ensure long-term stability, the method of execution described in the statement is incorrect and dangerous for production environments.

Infrastructure VMs in FusionAccess—such as theWI (Web Interface),HDC (Huawei Desktop Controller),ITA (IT Adapter), andGaussDB (Database)—are the "brains" of the desktop solution. Most of these components are deployed in active/standby or load-balancing pairs to ensure High Availability (HA). If an administrator were to run the reboot command on all Linux infrastructure VMs "at the same time," it would cause a complete service interruption. During this period, users would be unable to log in to their desktops, the management portal would be inaccessible, and active desktop sessions might lose their connection persistence.

The official Huawei documentation mandates astaggered restartapproach. For example, if there are two WI nodes, the administrator should restart the first node, verify it has returned to service, and only then proceed to restart the second node. This ensures that the "Service Plane" remains active at all times. Additionally, restarts should always be performed during off-peak hours to minimize the impact of the brief transition period between active and standby nodes. Therefore, while the frequency (quarterly) is correct, the instruction to restart them all simultaneously contradicts the fundamental principles of high-availability management within the Huawei ICT framework.

====================

In the HCIA–Cloud Computing curriculum, Ethernet switches are core components of the data center network and operate mainly at thedata link layer. One of their key functions isMAC address learning. When a switch receives a frame, it records thesource MAC addressand the corresponding incoming port in the MAC address table. This allows the switch to forward subsequent frames intelligently.

More importantly, a switchcan isolate collision domains, which makes the statement false. Each switch port represents anindependent collision domain, meaning that collisions occurring on one port do not affect other ports. This is a major improvement over hubs, which place all connected devices in a single collision domain.

However, switchesdo not isolate broadcast domainsby default. Broadcast traffic is forwarded to all ports within the same VLAN. Broadcast domain isolation requires technologies such asVLANs or routers.

Since the statement claims that a switchcannotisolate collision domains, which contradicts the HCIA definition of switching behavior, the correct answer isFALSE.

According to the Huawei HCIA-Cloud Computing curriculum, the definition of centralized storage is centered on the unified management of hardware components. The statement is TRUE as it accurately describes the physical architecture of traditional SAN (Storage Area Network) and NAS (Network Attached Storage) systems. In a centralized model, the storage system typically consists of two main parts: the Controller Enclosure and the Disk Enclosure.

The controller enclosure is the "brain" of the storage system. It contains the controllers (usually in a redundant pair for high availability), cache, and interface modules. Its role is to process I/O requests from servers, manage RAID configurations, and handle advanced data features like snapshots or replication. The disk enclosures, on the other hand, are the physical "shelves" that house the actual Hard Disk Drives (HDDs) or Solid State Drives (SSDs). These enclosures are connected to the controller enclosure via high-speed backend cables (such as SAS).

In this centralized architecture, the physical disks are not "visible" to the hosts directly. Instead, the controller abstracts these physical disks into a storage pool and then intoLUNs (Logical Unit Numbers). These LUNs are then mapped to service hosts (servers) via the storage network (FC or IP). This design allows for high performance and centralized management, as administrators can monitor and configure the entire storage resource pool from a single interface (such as Huawei DeviceManager). This is the standard deployment model for mission-critical applications in a Huawei FusionCompute environment, ensuring that storage resources are consolidated, secure, and easily scalable by adding more disk enclosures.

====================

According to the HCIA–Cloud Computing curriculum, the evolution of cloud computing architecture reflects changes intechnology openness, business importance, resource scale, and data characteristics.

OptionAis correct because early cloud platforms were often proprietary and closed, while modern cloud computing architectures increasingly adoptopen-source technologies(such as OpenStack and Kubernetes) and open architectures to improve interoperability and innovation.

OptionBis also correct. Cloud computing initially hostednon-critical workloadssuch as testing, development, and backup systems. As reliability, security, and availability improved, cloud platforms became capable of supportingmission-critical enterprise applications, including ERP, financial systems, and core business services.

OptionDcorrectly describes the evolution of cloud architecture. Early virtualization focused onsmall-scale resource integration, while modern cloud computing emphasizeslarge-scale resource pools, enabling centralized management, elastic scheduling, and efficient utilization of massive compute, storage, and network resources.

OptionCisfalse. The evolution of cloud computing data has movedfrom structured data to semi-structured and unstructured data, not the other way around. With the rise of big data, IoT, social media, logs, images, and videos, cloud platforms are increasingly designed to processmassive volumes of unstructured and semi-structured data, which is a key trend emphasized in HCIA learning materials.
