CompTIA Network+ (N10-008) — Question 826

A network technician is investigating a trouble ticket for a user who does not have network connectivity. All patch cables between the wall jacks and computers in the building were upgraded over the weekend from Cat 5 to Cat 6. The newly installed cable is crimped with a TIA/EIA 568A on one end and a TIA/EIA 568B on the other end. Which of the following should the technician do to MOST likely fix the issue?

Answer options

• A. Ensure the switchport has PoE enabled.
• B. Crimp the cable as a straight-through cable.
• C. Ensure the switchport has STP enabled,
• D. Crimp the cable as a rollover cable.

Correct answer: B

Explanation

The correct answer is B because a straight-through cable is required for connecting devices of different types, such as a switch to a computer. The current crimping method with different standards (TIA/EIA 568A and 568B) creates a crossover effect, preventing successful communication. The other options do not address the crimping issue directly related to the cable configuration.
