How many years will it take to recover the cost of building a basic transmission network (10G)?

Question

Options

• A3 years
• B5 years
• C6 years
• D4 years

• A
  71% (36)
• B
  18% (9)
• C
  8% (4)
• D
  4% (2)

Explanation

Option A (3 years) is the industry-standard payback period cited for a basic 10G transmission network in telecommunications network economics, particularly as referenced in vendor certification curricula (such as Huawei's ICT training materials). Network operators typically recover capital expenditure on a 10G backbone within this timeframe through leased capacity, service revenue, and operational efficiency gains.

The distractors are wrong because they all exceed the accepted benchmark: 4 years (D), 5 years (B), and 6 years (C) are plausible-sounding figures but do not match the standardized cost-recovery model used for basic 10G transmission infrastructure in the source material this question draws from.

Memory tip: Think "3G → 3 years" - just as 3G was the network generation before 10G became prevalent, the number 3 links directly to the 10G recovery period. The shortest answer among the choices is the correct one here, which mirrors the principle that 10G networks recoup costs faster than older, less efficient technologies.
