Latency <10 ps (B): Latency is low but not specified as picoseconds (ps); more likely microseconds (µs).

Thus, C is correct.

DC908’s key features, per HCSA-Sales-Transmission & Access, include:

Payback within 1 year (A): A core economic benefit.

Automatic Commissioning within 8 minutes (D): Simplifies deployment.

30%+ higher performance (B): Capacity is 47% higher, but "performance" isn’t phrased this way.

Thus, A and D are correct.

This statement directly reflects a well-documented pain point in DCI scenarios as per HCSA-Sales-Transmission & Access materials. The rapid growth of DCI traffic (over 50% annually) is driven by increasing data demands from cloud services, video streaming, and enterprise applications. Meanwhile, bandwidth costs doubling every two years exacerbate the financial burden on customers, pushing them toward cost-efficient solutions like Huawei’s DC908, which offers a payback period within 1 year for self-built networks. The statement accurately captures this dynamic, making it TRUE.

The Huawei OptiXtrans DC908 is designed for flexible deployment and can be co-deployed with IT devices in the same rack.

✅Compact Design – Supports 2U/5U chassis, allowing easy integration with IT servers and storage devices in standard 19-inch racks.

✅Reduced Space & Power Consumption – Eliminates the need for separate optical networking racks, saving data center space and power costs.

Thus, the correct answer is TRUE.

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.

A Passive Optical LAN (POL) network, as per HCSA-Sales-Transmission & Access, consists of:

OLT (Optical Line Terminal): The central device managing the network.

ODN (Optical Distribution Network): Passive infrastructure (e.g., fibers, splitters) connecting OLT to ONUs.

ONU (Optical Network Unit): The endpoint device at customer premises.

These are the core components of Huawei’s POL (e.g., Campus OptiX), making the statement TRUE.

DC908 features front air inlet and rear air outlet, per HCSA-Sales-Transmission & Access, for data center compatibility. The negation is incorrect, making it FALSE.

Customer pain points in transmission and access contexts (e.g., DCI, POL) are well-documented in HCSA-Sales-Transmission & Access:

High cost (B): Rising bandwidth and leased line costs are a universal concern across industries.

Difficult O&M (D): Complex operations and maintenance challenge customers, especially in DCI or legacy LANs.

High Availability (A): This is a requirement, not a pain point; customers seek it rather than suffer from it.

Frequent stock transactions (C): A financial sector need, not a general pain point in transmission/access.

Thus, B and D are the verified pain points.

The Huawei OptiXtrans DC908 is designed to offer a cost-effective DCI solution, and this statement is a verified key feature in HCSA-Sales-Transmission & Access documentation. The DC908’s high capacity (88T/fiber) and low per-bit cost enable customers to recover the investment in self-built networks within 1 year, compared to expensive leased lines. Additionally, the scalability (e.g., 100G to 800G per wavelength) means that higher bandwidth usage accelerates the payback period, as operational savings increase with scale. This economic advantage is a core selling point, making the statement TRUE.

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.

Finance DCI pain points include financial network attacks (cybersecurity) and financial disaster recovery, per HCSA-Sales-Transmission & Access. Frequent stock transactions are a business need, not a technical pain point. The statement omits disaster recovery and misclassifies stock transactions, making it FALSE.

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.

POL in Campus OptiX supports Wi-Fi roaming, Network Access Control (NAC), free mobility, and Software-Defined Networking (SDN) via ONUs with Wi-Fi 6 and eSight management, per HCSA-Sales-Transmission & Access. This versatility suits various office scenarios, making the statement TRUE.

Network design for Campus OptiX or DCI requires, per HCSA-Sales-Transmission & Access:

Project Background and Scope (A): Context and objectives.

Service types and bandwidth requirements (B): Defines capacity needs.

Project Scenario (C): Determines solution type (e.g., hotel, education).

Layout (include cabling) (E): Physical planning.

Construction period (D): Implementation detail, not design prerequisite.

Thus, A, B, C, and E are correct.

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.

The Huawei OptiXtrans DC908 is designed for flexible deployment in different data center environments. It supports:

✅197 ETSI rack compatibility – Ensuring industry-standard installation options.✅600mm, 800mm, 1000mm, and 1200mm depth installation – Making it adaptable to different rack sizes for seamless integration into various data centers.

Thus, the correct answer is TRUE.

Huawei’s Campus OptiX solution supports fast deployment and commissioning within 8 minutes due to the following features:

✅Plug and Play – No complex network planning required, as the system automatically detects and configures devices.
