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

Huawei's Campus OptiX (POL) solution uses a single optical fiber to carry multiple services simultaneously, including:

✅Wi-Fi – Fiber backhaul for wireless access points.✅Internet – High-speed broadband access.✅Telephone (VoIP/POTS) – Voice services over optical fiber.✅TV (IPTV, CATV) – Video transmission over the same infrastructure.

Since optical fiber has high bandwidth and low latency, it can efficiently transmit all these services using different wavelengths or logical VLANs.

Thus, the correct answer is TRUE.

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 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.

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

Passive Optical Networks (PON) use a Point-to-Multipoint (P2MP) topology where a single Optical Line Terminal (OLT) connects to multiple Optical Network Units (ONUs) or Optical Network Terminals (ONTs) using passive splitters.

✅Efficient Bandwidth Sharing – A single fiber from the OLT is split among multiple users, reducing fiber deployment costs.

✅Scalable and Cost-Effective – Supports higher user density with minimal fiber usage.

Since PON does not follow a Point-to-Point (P2P) model, the correct answer is P2MP.

POL stands for Passive Optical LAN in Huawei’s context, per HCSA-Sales-Transmission & Access. It applies PON technology to enterprise campuses, replacing traditional LANs with fiber-based, passive solutions. Other options (A, B, C) are unrelated, making D correct.

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.

The main PON (Passive Optical Network) technologies include:

GPON (Gigabit PON) – ITU-T G.984 standard

10G-PON (XG-PON/XGS-PON) – ITU-T G.987/G.9807.1 standard

NG-PON2 (Next-Generation PON2) – ITU-T G.989 standard

However, 15G-PON is not an officially recognized PON standard. There is no such technology defined under ITU-T or IEEE for PON-based networks.

Thus, the correct answer is 15G-PON, as it does not exist in the PON technology family.

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’s passive optical design (e.g., ODN with splitters) eliminates active equipment, reducing power consumption by up to 50% vs. active Ethernet, per HCSA-Sales-Transmission & Access,making the statement TRUE.

The All-Optical PON Architecture, as part of Huawei’s POL and Campus OptiX solutions, replaces traditional active Ethernet LANs with passive optical components, yielding significant engineering savings. According to HCSA-Sales-Transmission & Access documentation:

Cabling Space (A): Fiber optic cables are thinner and lighter than copper, reducing cabling space requirements.

IT Room Space (B): Passive architecture eliminates the need for intermediate active equipment (e.g., switches), freeing up IT room space.

Power Consumption (C): Passive components (e.g., splitters) require no power, significantly lowering energy use compared to active Ethernet setups.

Since all these aspects (A, B, C) are documented benefits, "All above" (D) is the correct answer.

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

Commissioning within 8 minutes (C): Critical for rapid deployment in finance.

Double stability (A): Not a specific metric; stability is enhanced but not quantified as "double."

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

Thus, C is correct.

Huawei's Campus OptiX (POL) solution offers higher profit margins for partners due to the following reasons:

✅Reduced Cabling and Equipment Costs – Since POL uses a single fiber infrastructure, it reduces hardware and installation costs, increasing margins.

✅Lower O&M Costs – With a passive network, there are fewer active components, reducing maintenance expenses and improving long-term profitability.

✅Faster Deployment = Faster Revenue – POL enables quick service deployment, allowing partners to scale operations efficiently.

Thus, partners can achieve a higher profit margin using Campus OptiX (POL) solutions.

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.

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.

Fiber optic cables in POL and DCI solutions have a lifecycle of 30 years, per HCSA-Sales-Transmission & Access, due to their durability and passive nature, making B correct.

Huawei’s Campus OptiX solution is a multi-service network capable of delivering all major digital services over a single optical fiber infrastructure:

✅Internet – High-speed broadband access via fiber.✅Telephone – Supports traditional POTS and VoIP services.✅Wi-Fi – Provides fiber backhaul for wireless access points (APs).✅TV (IPTV & CATV) – Distributes video services efficiently over the same network.

Since Campus OptiX can handle all these services, the correct answer is E (All of the above).

PON is Passive Optical Network, but it uses a point-to-multipoint (P2MP) topology, not P2P, per HCSA-Sales-Transmission & Access. P2P dedicates a fiber per user, while PON shares via splitters, making the statement FALSE.
