Which statement about Category 1 and 2 cables is true?

Which statement about Category 1 and 2 cables is true?

• A. They are not used for installation.
• B. They are rarely used in modern networks.
• C. They are the same as Category 5e.
• D. They are used for fiber backbones.

Answer: (A)

Category 1 and Category 2 cables are old, low-speed copper cabling that were used mainly for early voice networks. They don’t meet today’s Ethernet standards or support the data rates and performance required in modern networks. In new installations, technicians use higher-grade twisted-pair cables such as Cat5e, Cat6, or Cat6a to ensure adequate bandwidth, reliable performance, and proper installation practices. Because Cat1 and Cat2 cannot meet these requirements, they aren’t used for new network cabling. They might still appear in a few legacy telephone setups, but they’re not suitable for contemporary network installations. The other statements aren’t accurate: they’re not the same as Cat5e, and they’re not used for fiber backbones, which rely on optical fiber rather than copper categories.
