CompTIA A+ Core 1 (220-1101) — Question 83

A network technician has been tasked with creating a patch cable. The RJ45 connectors will not stay attached to the cable. Which of the following tools is needed to fix this issue?

Answer options

• A. Cable tester
• B. Crimper
• C. Punchdown tool
• D. Loopback plug

Correct answer: B

Explanation

The crimper is the correct tool because it securely attaches the RJ45 connectors to the cable by crimping the pins into the wire. A cable tester is used to check the integrity of the connection, a punchdown tool is for terminating cables into a patch panel or wall jack, and a loopback plug is used for testing network interfaces, none of which would resolve the issue of connectors not staying attached.
