CompTIA Network+ (N10-007) — Question 148

A network technician is designing a network cable upgrade in a newly acquired office space. The IT manager wants to install a standardized twisted pair cable solution that supports speeds up to 1 Gbps and terminates with a standard RJ45 connector. Which of the following cable types should the technician suggest?

Answer options

• A. SMF
• B. Cat 3
• C. Cat 5
• D. Cat 6
• E. RG-6

Correct answer: D

Explanation

The correct choice is Cat 6, as it supports speeds of up to 10 Gbps over short distances and is compatible with RJ45 connectors. Cat 5 can only support up to 100 Mbps, while Cat 3 is even slower and not suitable for modern networks. SMF and RG-6 are not twisted pair cables and are not designed for the specified requirements.
