問題 5
When a user VM uses a USB device, FusionAccess defaults to "USB Port Redirection". If the device is still unavailable, the"Device Redirection"policy can be configured.
正解：
Device RedirectionAccording to the Huawei HCIA-Cloud Computing training materials, the Huawei Desktop Protocol (HDP) offers two primary methods for handling USB peripherals: USB Port Redirection and USB Device Redirection (often referred to more broadly as high-level "Device Redirection").By default, FusionAccess utilizesUSB Port Redirection. This technology works at the physical layer, capturing the USB Request Blocks (URBs) from the client terminal and transmitting them to the virtual machine. This allows the Guest OS to "see" the raw USB device and use its own local drivers. This is the most compatible method for a wide range of devices such as specialized scanners or unique USB dongles.However, if a device is still unavailable or suffers from performance issues (common on high-latency WAN links), the administrator can configure the"Device Redirection"policy. This method operates at a higher logical level. Instead of redirecting the raw USB signals, it redirects the specific function of the device. For example, a USB flash drive can be redirected using "Client Drive Redirection," or a USB printer can be redirected via "Printer Redirection." This high-level redirection is more efficient as it optimizes the data flow for that specific device class, often providing a smoother user experience in constrained network environments. In the FusionAccess management portal (ITA), these policies are managed under "HDP Policy Management," where administrators can fine- tune which redirection method takes priority based on the specific hardware being used by the end-users.
