CompTIA A+ Core 1 (220-1001) — Question 138
An end user is unable to connect to the network, and a technician has visually verified the lights on the back of the PC are active and there is no physical damage to the Ethernet jack. Which of the following tools should the technician use to continue troubleshooting the connection?
Answer options
- A. Punchdown tool
- B. Tone generator and probe
- C. Cable tester
- D. Crimper
Correct answer: C
Explanation
The correct answer is C, as a cable tester can determine whether the Ethernet cable is functioning properly and if the signals are being transmitted correctly. The other options, such as a punchdown tool and crimper, are used for cable assembly rather than troubleshooting, while a tone generator and probe are more suited for identifying cable locations rather than testing their integrity.
