Huawei HCSA-Sales-Transmission & Access V2.0 H19-102_V2.0 Exam Questions

Answer : A

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.

Answer : A, C

In education (e.g., universities), Campus OptiX advantages, per HCSA-Sales-Transmission & Access, include:

1 Day Service Ready (A): Rapid deployment via POL.

100Mbps @ Everywhere (C): High bandwidth across campus.

1 Terminal @ 1 Room (B): More hotel-specific; education focuses on coverage.

Thus, A and C are correct.

Answer : A

PON, or Passive Optical Network, is a telecom technology that uses fiber optics and passive components (e.g., splitters) to deliver broadband access. According to HCSA-Sales-Transmission & Access documentation, PON operates in a point-to-multipoint (P2MP) topology, where a single Optical Line Terminal (OLT) at the service provider's end connects to multiple Optical Network Units (ONUs) or Optical Network Terminals (ONTs) at customer premises via a shared optical distribution network (ODN). This distinguishes it from point-to-point (P2P) systems, which dedicate a fiber per user. The statement accurately describes PON's definition and architecture, making it TRUE.

Answer : A

Passive Optical LAN (POL) is Huawei's all-optical solution for enterprise networks, replacing traditional copper-based LANs with fiber optics. HCSA-Sales-Transmission & Access materials confirm that POL, part of the Campus OptiX portfolio, is designed for enterprise environments and is widely applicable in scenarios such as:

Education (e.g., universities),

Healthcare (e.g., hospitals),

Airports,

Electric power, and

Smart cities.

Its benefits include simplified architecture, high bandwidth, and long-distance coverage (up to 40km), making the statement TRUE.

Answer : B

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.

Answer : A

Huawei is a leading provider of networking solutions, offering a broad portfolio that includes both Ethernet-based switches and Passive Optical Network (PON)-based POL products. According to HCSA-Sales-Transmission & Access documentation, Huawei's Ethernet switches (e.g., CloudEngine series) cater to traditional IP networks, while its POL series (e.g., Campus OptiX with OLTs and ONUs) leverages PON technology for all-optical enterprise LANs. This dual capability allows Huawei to address diverse customer needs, from traditional LANs to modern optical deployments, making the statement TRUE.

Answer : B, C, D

The highlights of 'Ultra broadband & High Integration' pertain to Huawei's advanced transmission solutions, such as the OptiXtrans DC908, designed for DCI scenarios. According to HCSA-Sales-Transmission & Access materials:

Hybrid photoelectric integration (B): This feature integrates optical and electrical components, reducing complexity and improving efficiency, a hallmark of Huawei's high-integration designs.

9.6T/2U (C): The DC908 delivers an industry-leading capacity of 9.6 terabits per second in a compact 2U form factor, emphasizing ultra-broadband capability and space efficiency.

100G~800Gbit@per X (D): This refers to the flexible, scalable bandwidth per port (ranging from 100G to 800G), a key feature for ultra-broadband applications in DCI.

Hardware redundancy (A): While important for reliability, it is not specifically highlighted under 'Ultra broadband & High Integration' but rather under stability or resilience features.

Thus, B, C, and D are the verified highlights.
