Huawei H19-102_V2.0 Practice Test - Questions Answers, Page 3

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.

DCI stands for Data Center Interconnect, a term widely used in the industry and explicitly defined in HCSA-Sales-Transmission & Access materials. It refers to technologies (e.g., Huawei OptiXtrans DC908) that link multiple data centers for high-speed, low-latency data transfer. The statement is accurate, 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 network management. The statement negates these documented issues, making it FALSE. (Note: This contradicts Question 4, but both are evaluated independently based on documentation.)

Huawei's OptiXaccess brand encompasses a broader range of access network solutions, not just ONUs. HCSA-Sales-Transmission & Access materials describe OptiXaccess as including OLTs, ONUs, and related PON equipment for enterprise and residential access, not solely the ONU series. The statement's narrow scope is incorrect, making it FALSE.

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.

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.

The Huawei EA5800-X2 is a compact OLT model in the SmartAX series, used in PON deployments like Campus OptiX. HCSA-Sales-Transmission & Access documentation specifies that it supports 2 service-card slots, balancing capacity and size for small-to-medium scenarios. Thus, B is the correct answer.

The OptiXtrans DC908's specifications in HCSA-Sales-Transmission & Access highlight:

Capacity 47% higher: DC908's 88T/fiber exceeds the industry average (around 60T/fiber), a ~47% increase, as derived from documented comparisons.

Power consumption 35% lower: At 0.13 W/G vs. the industry's 0.2 W/G, it achieves a 35% reduction.

Both claims align with DC908's key features, making the statement TRUE.

The DC908 is designed for DCI with IT compatibility. HCSA-Sales-Transmission & Access confirms it supports co-deployment with IT devices in the same rack, featuring a 2U form factor, front-to-rear airflow, and rack-standard dimensions (e.g., 19-inch ETSI). The statement's negation is incorrect, making it FALSE.
