SK0-003 · Question #720
Which of the following cable types should be used to achieve Gigabit Ethernet speed?
The correct answer is C. CAT6. CAT6 cable is recommended and commonly used to reliably achieve Gigabit Ethernet speeds (1000BASE-T) over longer distances due to its improved specifications.

Why each option
CAT6 cable is recommended and commonly used to reliably achieve Gigabit Ethernet speeds (1000BASE-T) over longer distances due to its improved specifications.
CAT5 cable is typically rated for 10/100 Mbps Ethernet; while CAT5e can support Gigabit Ethernet, CAT5 itself is not the optimal or most reliable choice for Gigabit speeds over full distances.
CAT3 cable is an older standard designed for voice communications and 10 Mbps Ethernet (10BASE-T) only; it cannot support Gigabit Ethernet speeds.
CAT6 (Category 6) cable is designed and certified to support Gigabit Ethernet (1000BASE-T) over distances up to 100 meters and can even support 10 Gigabit Ethernet over shorter distances. Its enhanced specifications provide better resistance to crosstalk and noise compared to older categories, ensuring reliable high-speed data transmission.
Thicknet (10BASE5) is a legacy coaxial cable standard for 10 Mbps Ethernet and is completely unsuitable for modern Gigabit Ethernet speeds.
