Free Practice Questions for Huawei H19-102_V2.0 Exam

A self-built Data Center Interconnect (DCI) provides several advantages:

✅High Efficient O&M – With self-built DCI, enterprises have full control over network monitoring, fault management, and performance optimization, reducing dependency on external providers.

✅Service Rollout on Time – Unlike leased lines, a self-built DCI network allows rapid service deployment without waiting for telecom operators, improving efficiency.

❌Guaranteed Quality – While a self-built network offers more control, it does not always guarantee quality compared to carrier-grade leased lines with SLAs (Service Level Agreements).

Thus, the correct answer is A and C.

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 finance industry heavily relies on DCI solutions for data replication, high availability, and disaster recovery. Key pain points include:

✅Increased leased line prices – Financial institutions require dedicated high-bandwidth connections, and leased line costs continue to rise.

✅Financial disaster recovery – To meet compliance regulations and business continuity requirements, banks and financial firms must deploy redundant DCI networks for real-time data backup and disaster recovery.

Thus, the correct answer is TRUE.

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.

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 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.

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.

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.

Campus OptiX (IP+POL) saves investment, per HCSA-Sales-Transmission & Access:

Capex: Reduces costs for active equipment (fewer switches), cabling (fiber vs. copper), and construction (simplified architecture).

Opex: Lowers power, maintenance, and operational costs due to passive design.

Option C fully captures these savings, making it correct.

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.
