CompTIA A+ Core 1 (220-1101) — Question 515

A field technician has been dispatched to a site with an internet outage. Upon arriving, the technician discovers that the POTS lines are not working as well. Which of the following technologies is the site MOST likely using?

Answer options

• A. Fiber
• B. Cable
• C. DSL
• D. Satellite

Correct answer: C

Explanation

The correct answer is C, DSL, because it operates over POTS lines, and if those lines are down, DSL service would also be impacted. Fiber, Cable, and Satellite do not rely on POTS lines, so their functionality would not be directly affected by issues with those lines.
