In Huawei FusionAccess, user authentication and authorization for Windows desktops are typically integrated withActive Directory (AD). During VM template creation, the option“Configure user login”is used to specify who is allowed to log in to the virtual desktop.

According to the HCIA–Cloud Computing FusionAccess service provisioning process, this option is selected whenAD group membersare intended to access the VM. FusionAccess then uses AD-based authentication to control desktop login permissions, ensuring centralized identity management and consistent security policies.

Therefore, the correct word shown on the GUI and required to complete the sentence isAD.

In the official Huawei HCIA–Cloud Computing documentation, the core definition of virtualization centers on the abstraction of physical resources. The essence of virtualization technology is precisely the transformation of physical, hardware-based resources—such as CPUs, memory, network interface cards, and storage disks—into virtualized, logical entities. This process is facilitated by a software layer known as the Hypervisor or Virtual Machine Monitor (VMM). By creating this abstraction layer, virtualization effectively achieves the "decoupling" of the software environment (the Operating System and applications) from the underlying physical hardware.

This decoupling is a revolutionary shift from traditional computing architectures where an Operating System was tied to specific hardware drivers and physical configurations. In a virtualized environment, a Virtual Machine (VM) perceives a set of standardized, logical hardware components provided by the Hypervisor. Because the software is no longer bound to the physical machine, it gains significant mobility and flexibility. For example, in Huawei’s FusionCompute platform, this decoupling allows for features such as Live Migration, where a running VM can be moved from one physical host to another without any service interruption. This is possible because the VM's "logical" hardware remains consistent even as the "physical" host changes.

Furthermore, this transformation from physical to logical enables better resource utilization through overcommitment and sharing. Multiple logical servers can run on a single physical server, each isolated from the others. This fundamental shift is what provides the agility, scalability, and efficiency required for Cloud Computing. Without the decoupling provided by virtualization, the rapid provisioning and elastic resource scaling that define cloud services would be impossible to achieve. Therefore, virtualization serves as the indispensable technical foundation upon which all other cloud services and management layers are built within the Huawei ICT ecosystem.

As detailed in the Huawei FusionAccess documentation for the HCIA curriculum, the Huawei Desktop Protocol (HDP) is designed to optimize the user experience in Virtual Desktop Infrastructure (VDI). Statement A is correct: HDP features "Intelligent identification of video data."8 The protocol can automatically distinguish between standard GDI (Graphics Device Interface) desktop elements and active video streams.9 When video is detected, HDP switches to specialized compression algorithms (such as H.264 or H.265) to ensure efficient encoding and reduced bandwidth consumption.

Statement B is also a verified function. HDP employsDynamic Frame Rate Adjustment.10By monitoring the network quality (latency and packet loss) in real-time, the protocol can adjust the frame rate (e.g., from 60fps down to 30fps or lower) to maintain a smooth, jitter-free playback experience even on unstable or low-bandwidth links. Statement C is true as HDP supports multiple rendering modes. In "Multimedia Redirection," the video stream is decoded on theclientside (using local hardware acceleration), while in other modes, decoding occurs on theserver(VM) with the resulting images sent to the client. This dual-support flexibility ensures compatibility across various terminal types.

Statement D isincorrectbecause of the "maximum of 2K videos" limitation. According to the official HCIA-Cloud Computing V5.5 and FusionAccess technical guides, HDP@Media technology (multimedia redirection) explicitly supports4K UHDvideo playback, not just a maximum of 2K. While D correctly mentions "automatic reconnection" and "dynamic traffic adjustment," the resolution limit is technically outdated for the current Huawei cloud ecosystem. Thus, for the purposes of the HCIA certification, only A, B, and C are fully accurate representations of HDP's high-fidelity audiovisual capabilities.

According to the Huawei HCIA-Cloud Computing training materials, the statement is TRUE. TAP (Network TAP) is a virtual network kernel device that is part of the standard Linux kernel networking stack.2 It is "independently maintained" because it is a native Linux feature, not a proprietary tool built solely for a specific hypervisor like KVM or Xen. TAP devices operate at the Data Link Layer (Layer 2) of the OSI model, meaning they handle Ethernet frames.3

In a cloud computing environment, TAP devices are fundamental for bridging the gap between virtual machines and the physical network. When a Virtual Machine is created, the hypervisor (CNA in Huawei's case) creates a TAP device on the host. One end of this TAP device is "plugged" into the virtual machine's NIC, while the other end is connected to a virtual switch (like the DVS or Linux Bridge). This allows the VM to send and receive Ethernet frames as if it were connected to a physical switch port.

Linux maintains TAP alongside its counterpartTUN(which operates at Layer 3/Network Layer).4Because TAP carries full Ethernet headers, it is the preferred device for virtual switches, as it allows for features like VLAN tagging and MAC address learning. Huawei’s virtualization technology leverages these standard Linux kernel features to provide a high-performance, stable networking environment. Understanding that TAP is a standard, independent Linux kernel component is vital for candidates, as it explains how open-source foundations are used to build enterprise-grade cloud platforms like FusionCompute.
