H19-102_V2.0 HCSA-Sales-Transmission & Access V2.0 Questions and Answers

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.

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 a Data Center Interconnect (DCI) solution tailored for high-performance, low-latency, and simplified deployment in data center scenarios. While Huawei’s optical solutions, including the DC908, are widely deployed globally, the specific claim of "620,000+ optical devices commercially used worldwide" is not explicitly documented as a key feature of the DC908 in official HCSA-Sales-Transmission & Access materials. The DC908’s key features focus on aspects like high capacity (e.g., 88T per fiber), low power consumption (35% lower than the industry average), rapid commissioning (within 8 minutes), and cost-effective payback (within 1 year for self-built networks). The figure of 620,000+ devices might pertain to Huawei’s broader optical portfolio, but it is not a verified key feature specific to the DC908. Thus, the statement is FALSE in this context.

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.

Campus networks today face several key challenges:

✅Hard to expand/upgrade cabling system – Traditional Ethernet-based campus networks require extensive copper cabling, which is difficult to expand and upgrade, leading to higher costs and complexity.

✅Chimney networks hard to maintain – Many legacy campus networks operate in a chimney-style architecture (vertical silos of network systems), making it difficult to manage and integrate different services.

❌Restriction of 100m makes network complex – While Ethernet has a 100m distance limit, modern fiber-based Passive Optical LAN (POL) solutions overcome this restriction, making this less of a challenge today.

❌Devices are too large – Modern networking equipment is compact and modular, making device size less of a concern in today’s campus networks.

Thus, the correct answers are A and D.

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.

The WebGUI (Web-based Graphical User Interface) for Huawei solutions like the OptiXtrans DC908 is designed for user-friendly management, including single-device scenarios. HCSA-Sales-Transmission & Access confirms that WebGUI can configure and monitor a standalone device (e.g., DC908), not just multi-device networks. The statement’s negation is incorrect, making it FALSE.

Huawei’s Campus OptiX, based on POL, is versatile for enterprise scenarios. HCSA-Sales-Transmission & Access documents confirm its deployment in:

Education (University): Supports high-bandwidth, long-distance (40km) campus networks.

Hotel: Offers fiber-to-room and cost-efficient solutions.

The statement is accurate, making it TRUE.

Passive Optical LAN (POL) is an all-optical enterprise networking solution comprising Optical Line Terminals (OLT) and Optical Network Units (ONU). In office scenarios, Huawei’s Campus OptiX POL solution allows flexibility in deployment. Official HCSA-Sales-Transmission & Access documents confirm that OLTs and ONUs can be sold independently based on customer needs, such as upgrading existing infrastructure or deploying specific components in a phased approach. For example, an office might procure an OLT to centralize management while adding ONUs later to expand coverage. This modularity supports tailored solutions, making the statement TRUE.

Huawei’s OLT family (SmartAX series) includes models like EA5800-X17, X7, X2, and others, totaling at least 4 variants, per HCSA-Sales-Transmission & Access, making A correct.

In Data Center Interconnect (DCI) scenarios, high-level customers—such as large enterprises, ISPs, and financial institutions—face significant challenges, as outlined in HCSA-Sales-Transmission & Access documentation. The two major pain points are:

High costs: DCI traffic grows rapidly (over 50% annually), and bandwidth costs often double every two years, making cost management a critical issue.

Difficult O&M (Operations & Maintenance): Traditional DCI setups involve complex network planning and maintenance, often requiring skilled engineers, which increases operational complexity.

Huawei’s OptiXtrans DC908 addresses these with lower per-bit costs (e.g., 88T/fiber capacity) and simplified O&M (e.g., one-click deployment). The statement aligns with documented customer pain points, making it TRUE.

High-level customers in DCI scenarios (e.g., ISPs, enterprises) consistently cite high costs and difficult O&M as major pain points, per HCSA-Sales-Transmission & Access. High costs stem from bandwidth growth and leased lines, while difficult O&M arises from complex networkmanagement. The statement negates these documented issues, making it FALSE. (Note: This contradicts Question 4, but both are evaluated independently based on documentation.)

WebGUI supports single-device management (e.g., DC908), per HCSA-Sales-Transmission & Access, offering configuration and monitoring, 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.

eSight NMS, used in Campus OptiX, has features per HCSA-Sales-Transmission & Access:

Installation easy (B): Quick setup for unified management.

Simple detection (C): Efficient fault identification.

Clear visualization (D): Intuitive network monitoring.

Free upgrade (A): Not a standard feature; upgrades may involve licensing.

Thus, B, C, and D are correct.

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.

The DC908 does not explicitly support SCC (System Control Card) 1+1 redundancy, per HCSA-Sales-Transmission & Access. While it offers hardware reliability, SCC redundancy is more associated with OLTs (e.g., EA5800), not DCI-focused DC908, making the statement FALSE.

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

Co-deployed with IT devices (A): Supports rack integration with IT equipment.

Front air inlet and rear air outlet (C): Matches data center cooling standards.

AC/HVDC/DC power supply (D): Offers flexible power options (AC, high-voltage DC, DC).

19-inch ETSI rack installation (B): While compatible with 19-inch racks, "ETSI" typically implies European telecom standards (e.g., 21-inch), and DC908’s primary focus is 19-inch IT racks; this is not a highlighted feature.

Thus, A, C, and D are correct.

POL simplifies traditional multi-layer LANs (e.g., core, aggregation, access) into a 2-layer architecture (OLT to ONU via ODN), per HCSA-Sales-Transmission & Access. This reduces complexity and equipment, making the statement TRUE.
