Networking Fundamentals — Question 14

Which feature of Category 5e STP cable reduces external interference?

Answer options

• A. Crosstalk
• B. Shielding
• C. Length
• D. Twisting

Correct answer: D

Explanation

Twisting in Category 5e STP cable helps to keep the wire pairs closely bound, which cancels out electromagnetic interference from external sources. While shielding also serves to protect against interference, it is the twisting of the pairs specifically that is primarily responsible for reducing crosstalk and external interference. Length and crosstalk do not directly contribute to minimizing interference in the same way.
