DC908 is front air inlet and rear air outlet.
Answer(s): A
The Huawei OptiXtrans DC908 is designed for data center compatibility, including physical integration with IT racks. HCSA-Sales-Transmission & Access documents specify that the DC908 features a front air inlet and rear air outlet cooling design, aligning with standard data center rack airflow patterns (front-to-back). This ensures efficient thermal management in dense deployments, making the statement TRUE.

Which of the following are Huawei's Strengths when dealing with technical-level customers?
Answer(s): A,B,C
Huawei's technical strengths, particularly for DCI and optical solutions like the DC908, resonate with technical-level customers (e.g., engineers, CTOs). Per HCSA-Sales-Transmission & Access:Maximum bandwidth per wavelength (A): Huawei's in-house 800G oDSP chips enable industry- leading per-wavelength capacity, a key technical advantage.Simplest O&M (B): Distributed Light Sensor technology simplifies optical-layer management with one-click and zero-touch deployment, reducing complexity.Widest spectrum (C): Super C+L band support expands capacity to 220 wavelengths (11 THz), far exceeding traditional C-band (4 THz), a standout feature.All options (A, B, C) are verified technical strengths.

What are the following advantages of Campus OptiX in the hotel scenario?
Answer(s): B,C
In the hotel scenario, Huawei's Campus OptiX (POL-based) offers tailored advantages, as per HCSA- Sales-Transmission & Access:Best TCO (B): POL reduces cabling, power, and maintenance costs, delivering the best Total Cost of Ownership compared to traditional LANs.1 Fiber for 1 Room (C): The solution supports a fiber-to-the-room architecture, providing high bandwidth and scalability for guest rooms.Wi-Fi "0" Interrupt (A): While POL supports excellent Wi-Fi (e.g., via ONUs with Wi-Fi 6), "zero interrupt" is not a specifically highlighted advantage in hotel scenarios; it's more emphasized in office roaming contexts.Thus, B and C are the verified advantages.

88T per fiber: Maximum capacity: 88T/fiber vs. 60T/fiber; 6.4T/U vs. 3.6T/U. Huawei has the lowest per-bit cost. Lowest power consumption: 0.13 W/G vs. 0.2 W/G, power consumption is 35% lower than the industry average.
This statement aligns with the Huawei OptiXtrans DC908's key specifications in HCSA-Sales- Transmission & Access documents:88T/fiber vs. 60T/fiber: DC908 achieves 88 terabits per fiber using Super C+L band, surpassing the industry's 60T/fiber average.6.4T/U vs. 3.6T/U: It delivers 6.4T per rack unit (U), higher than the industry's 3.6T/U, optimizing space efficiency.Lowest per-bit cost: High capacity and efficiency reduce the cost per bit, a core DC908 selling point.Power consumption (0.13 W/G vs. 0.2 W/G): DC908's 0.13 watts per gigabit is 35% lower than the industry's 0.2 W/G, as verified.The statement is fully accurate, making it TRUE.

What is the next generation for Wi-Fi 5?
Wi-Fi 5, based on the 802.11ac standard, is succeeded by Wi-Fi 6 (802.11ax), as per industry standards and HCSA-Sales-Transmission & Access materials. Wi-Fi 6 offers higher throughput, better efficiency, and support for more devices, making it the next generation. "Wi-Fi X" and "GWiFi" are not recognized standards or successors, so A is the correct answer.
