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

Answer : A

The Huawei OptiXtrans DC908 is designed for data center compatibility, including physical integration with IT racks. HCSA-Sales-Transmission & Access documents specify that the DC908 features a front air inlet and rear air outlet cooling design, aligning with standard data center rack airflow patterns (front-to-back). This ensures efficient thermal management in dense deployments, making the statement TRUE.

Answer : B

DCI is Data Center Interconnect, per HCSA-Sales-Transmission & Access. The negation is incorrect, making it FALSE.

Answer : A

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.

Answer : A

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.

Answer : B, C

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.

Answer : A

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.

Answer : B

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.
