CompTIA Network+ (N10-007) — Question 679

A network technician is building a network for a small office. The office currently has cable TV and now requires access to the Internet without adding any cabling other than what is already in place. Which of the following solutions should the technician install to meet these requirements?

Answer options

• A. DOCSIS modem
• B. Wireless router
• C. DSL modem
• D. Access point

Correct answer: A

Explanation

The correct answer is A, as a DOCSIS modem utilizes the existing cable TV infrastructure to deliver Internet service over coaxial cables. Options B and D are not suitable because they do not provide a direct Internet connection via the existing cable system, and option C is incorrect since a DSL modem requires a telephone line, not cable.
