Show answer & explanation
Correct answer: A
Correct answer: twisted pair, 100 metres.
100Base-TX is a Fast Ethernet standard for 100 Mbps Ethernet over twisted-pair copper cabling, typically Category 5 or better UTP/STP.
Cable type: “T” indicates twisted pair; “TX” is the common two-pair Fast Ethernet copper variant.
Maximum segment length: The standard maximum link/segment length for 100Base-TX over twisted pair is 100 metres.
Why fibre options fail: Fibre-based Fast Ethernet variants have different names, such as 100Base-FX, so they do not describe 100Base-TX.
