A consultant has been hired to wire a simple small office of ten computers to a layer 2 Ethernet 100BaseT switch. Which of the following cabling will be needed for the installation?

The correct answer is C. CAT6a. 100BaseT (Fast Ethernet) requires twisted-pair copper cabling. CAT6a supports speeds up to 10 Gbps and is fully backward compatible with 100BaseT, making it a valid and future-proof choice. CAT3 (choice D) only supports up to 10 Mbps (10BaseT) and cannot reliably run 100BaseT…

Explanation

100BaseT (Fast Ethernet) requires twisted-pair copper cabling. CAT6a supports speeds up to 10 Gbps and is fully backward compatible with 100BaseT, making it a valid and future-proof choice. CAT3 (choice D) only supports up to 10 Mbps (10BaseT) and cannot reliably run 100BaseT. Multimode fiber (choice A) requires fiber-optic NICs and infrastructure not described here. RG-59 coaxial (choice B) is used for cable television, not modern Ethernet. CAT6a is the only listed copper twisted-pair option that meets the 100BaseT standard.
