Which category of UTP wiring is rated for 100BaseT Ethernet networks?

A.
Category 5

B.
Category 1

C.
Category 2

D.
Category 3
E. Category 4

Explanation:
Category 5 unshielded twisted-pair (UTP) wire is rated for
transmissions of up to 100 Mbps and can be used in 100BaseT
Ethernet networks. It is the most commonly installed type of UTP at
this time. See Table.
Category 1 twisted-pair wire was used for early analog telephone communications and is not
suitable for data.
Category 2 twisted-pair wire, was used in AS/400 and IBM 3270 networks. Derived from IBM Type
3 cable specification.
Category 3 twisted-pair wire, is rated for 10 Mbps and was used in 802.3 10Base-T Ethernet
networks, and 4 Mbps Token Ring networks.
Category 4 twisted-pair wire, is rated for 16 Mbps and is used in 4/16 Mbps Token Ring LANs.
