CompTIA A+ 220-1101 Practice Question

A cable tester is specifically designed to test the integrity of cable pairs and ensure the correct pinout configuration. This tool will check for problems such as open wires, shorts, crossed pairs, and other issues that might affect data transmission. While the other tools listed are useful in different contexts, such as setting up or diagnosing network issues, the cable tester is the best choice for directly testing the physical cables themselves.
