Which Ethernet category uses unshielded cable and supports up to 100 Mbps?

Explanation:
This tests how Ethernet category names map to cabling type and the speed they’re designed to support. The category designed for unshielded twisted‑pair cabling with a maximum of 100 Mbps is the older standard used for Fast Ethernet, defined for 100BASE-TX over unshielded copper. That combination—unshielded cable and a 100 Mbps ceiling—pins it to Cat 5. Later categories, like Cat 5e, Cat 6, and Cat 7, still use copper but are built for higher speeds (Cat 5e up to 1 Gbps, Cat 6/7 even higher) and often involve shielding, which is why they aren’t limited to 100 Mbps.
