Question
A small office needs to connect one new system to their network in a distant office, but does not have the resources to install a new Ethernet wall jack, and does not want to use wireless. Which of the following is a simple, cost effective option for providing connectivity?
Options
- ASONET
- BMultimode fiber
- C802.11n
- DBroadband over Power Line
Explanation
Broadband over Power Line (BPL) uses existing electrical wiring to deliver network connectivity, making it ideal when no Ethernet cabling is available and wireless is not desired.
Common mistakes.
- A. SONET is a carrier-grade fiber optic transport technology requiring substantial infrastructure investment, not a simple or low-cost option for a small office.
- B. Multimode fiber requires installing new cable runs with compatible switches and NICs, which is neither simple nor cost effective when avoiding new cabling.
- C. 802.11n is a wireless standard, which the scenario explicitly rules out as an undesired option.
Concept tested. Broadband over Power Line as network extension option
