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D correctly mentions "automatic reconnection" and "dynamic traffic adjustment," the resolution limit is technically outdated for the current Huawei cloud ecosystem.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.
