If you are wiring a new building for data networks, you should plan for at least which category?

• A. Category 6 or higher
• B. Category 5e
• C. Category 3
• D. Category 7

Answer: (A)

When wiring a new building for data networks, the goal is to choose a cabling standard that will handle current needs while leaving room for growth. Category 6 is the minimum you should plan for because it reliably supports 1 Gbps Ethernet over the full 100-meter link and can handle 10 Gbps over shorter distances, all with tighter specs that reduce crosstalk and noise compared with older cables. This makes it a practical baseline for a new build, balancing cost and future-proofing. Category 5e is older and may meet basic needs today, but it isn’t as capable for future upgrades to higher speeds. Category 3 is obsolete for data networks, and Category 7 is seldom necessary for typical office layouts and adds complexity and cost due to its shielding and differing connectors. For even more headroom, many projects opt for Category 6A or higher, but minimum for a forward-looking installation is Category 6.
