CompTIA Network+ (N10-008) — Question 469

A technician is troubleshooting network connectivity from a wall jack. Readings from a multimeter indicate extremely low ohmic values instead of the rated impedance from the switchport. Which of the following is the MOST likely cause of this issue?

Answer options

• A. Incorrect transceivers
• B. Faulty LED
• C. Short circuit
• D. Upgraded OS version on switch

Correct answer: C

Explanation

The most likely cause of extremely low ohmic values is a short circuit, which can create a path of little to no resistance. The other options, such as incorrect transceivers or a faulty LED, would not typically result in such low measurements, nor would an upgraded OS on the switch affect the electrical characteristics being measured.
