CompTIA A+ Core 1 (220-1001) — Question 53

During an inspection, it was found that data racks were not properly grounded. To pass the inspection and address a growing concern to protect data cabling and equipment, a technician must make sure all racks are properly grounded.
Which of the following tools should the technician use to verify this has been completed?

Answer options

• A. Multimeter
• B. Cable tester
• C. Tone generator
• D. Voltmeter

Correct answer: A

Explanation

The correct tool for verifying that racks are properly grounded is a multimeter, as it can measure resistance and ensure that the grounding is adequate. A cable tester is used to check network cables for continuity and performance, not grounding. A tone generator is used to trace cable paths and identify wiring issues, while a voltmeter measures voltage, which is not directly applicable to grounding verification.
