In commercial work, the demarcation point is typically within how many feet of the building network entrance cabling?

• A. 30 ft
• B. 100 ft
• C. 50 ft
• D. 15 ft

Answer: (C)

In commercial work, the demarcation point marks the boundary where the service provider’s responsibility ends and the customer’s begins, and it’s placed close to where the external network enters the building. The typical convention is to locate this handoff within about 50 feet of the building’s network entrance cabling. This distance keeps the handoff practical for testing and maintenance, provides a clear boundary for ownership and responsibility, and fits with where interior telecom equipment and pathways are commonly located. Shorter distances would blur the boundary, while longer runs would complicate access and management for both parties, making 50 feet the most workable standard in practice.
