Introduction to Networking Concepts Practice Test

This question tests understanding of how different category cables specify maximum data rates over a given distance. Cat4 was designed to support up to 16 Mbps over 100 meters, which matches the specification in the question. It’s rarely used today because newer cables offer much higher bandwidth and better performance while still working with the same connectors and networks.

The other options don’t fit the 16 Mbps at 100 meters: Cat5 and Cat5e are designed for much higher speeds (Cat5e commonly 1 Gbps at 100 meters), and Cat6 supports even higher speeds (10 Gbps at shorter distances, and 1 Gbps at 100 meters). Thus, only Cat4 matches the 16 Mbps at 100 meters and is the one that’s now mostly obsolete.
