Question #: 630
Topic #: 1
Which of the following twisted pair cables supports 10GBASE-T data transmission speed?

Suggested Answer: D Vote an answer

The correct answer is D. Cat 6a.
Cat 6a (augmented) is a type of twisted pair cable that supports 10GBASE-T data transmission speed.
10GBASE-T is an Ethernet standard that can deliver 10 gigabits per second (Gbps) over copper cables. Cat 6a can support this speed up to a distance of 100 meters, which is the same as Cat 5e and Cat 6 for lower speeds.
Cat 6a has better shielding and crosstalk prevention than Cat 6, which makes it more suitable for high-frequency signals.
Cat 3, Cat 5, and Cat 5e are not capable of supporting 10GBASE-T data transmission speed. Cat 3 can only support up to 10 Mbps, Cat 5 can only support up to 100 Mbps, and Cat 5e can only support up to 1 Gbps.
These cables have lower bandwidth, higher attenuation, and more interference than Cat 6a.
