N10-005 Question #952: Real Exam Question with Answer & Explanation

The correct answer is C: DB loss. CAT6 Ethernet cable has a maximum specified transmission distance of 100 meters (328 feet). The installed cable is 182.88 meters (600 feet) - nearly double the maximum. At this excessive distance, the electrical signal attenuates (loses strength), which is measured in decibels (d

Question

A technician installs a new CAT6 cable from one end of the office building to another, a total distance of 600 feet (182.88 meters). When a laptop is connected to the cable, it cannot connect to the Internet. Which of the following is MOST likely the cause of this problem?

Options

ABad connectors
BCrosstalk
CDB loss
DTXRX reversed

Explanation

CAT6 Ethernet cable has a maximum specified transmission distance of 100 meters (328 feet). The installed cable is 182.88 meters (600 feet) - nearly double the maximum. At this excessive distance, the electrical signal attenuates (loses strength), which is measured in decibels (dB). This dB loss causes the signal to degrade below the threshold required for reliable communication, resulting in no connectivity. Bad connectors and TXRX reversal would typically cause link failure regardless of distance, and crosstalk is a near-end noise issue rather than a distance-related one.
