A technician is receiving reports that the entire office sporadically loses network connectivity throughout the day. The technician determines the root cause to be EMI.
Which of the following cable mediums would be the MOST cost effective without sacrificing system performance?
A . Coaxial
B. Shielded Cat 6
C. Plenum Cat 5e
D. Multimode fiber
Answer: B
Explanation:
In this situation, the MOST cost-effective cable medium that would not sacrifice system performance would be B. Shielded Cat 6. Electromagnetic interference (EMI) can disrupt network connectivity by interfering with the signals transmitted over network cables. Shielded Cat 6 cables are designed to provide protection against EMI by incorporating a layer of shielding material around the cable’s conductors. This shielding helps to prevent EMI from interfering with the signals transmitted over the cable.
