simplified O&M (e.g., one-click deployment). The statement aligns with documented customer pain points,
making it TRUE.
Reference: HCSA-Sales-Transmission & Access, DCI Scenarios Pain Points section.
5.Customer pain point: High costs. DCI traffic grows over 50% annually, while bandwidth cost doubles
every two years.
A. TRUE
B. FALSE
Answer: A
Explanation:
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.
