CompTIA Network+ (N10-009) — Question 454

Three access points have Ethernet that runs through the ceiling. One of the access points cannot reach the internet. Which of the following tools can help identify the issue?

Answer options

• A. Network tap
• B. Cable tester
• C. Visual fault locator
• D. Toner and probe

Correct answer: B

Explanation

The correct answer is B, the cable tester, as it is specifically designed to check the integrity and connectivity of Ethernet cables, helping to identify any faults. The other tools, while useful in different scenarios, do not directly assess cable integrity: a network tap monitors traffic, a visual fault locator identifies breaks in fiber optic cables, and a toner and probe is used for tracing cables.
