Which of the following statements is false about virtual NICs?

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.
