CompTIA A+ Core 1 (220-1101) — Question 506

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?

Answer options

• A. Coaxial
• B. Shielded Cat 6
• C. Plenum Cat 5e
• D. Multimode fiber

Correct answer: B

Explanation

The correct answer is B, Shielded Cat 6, as it provides better protection against EMI compared to the other options while still being cost-effective. Coaxial (A) may not offer the same performance for data transmission, and Plenum Cat 5e (C) does not have shielding, making it less suitable for EMI issues. Multimode fiber (D) is typically more expensive and may not be necessary for the level of performance needed.
