Which category provides up to 1 Gbps with 250 MHz bandwidth and is described as shielded/unshielded?

Which category provides up to 1 Gbps with 250 MHz bandwidth and is described as shielded/unshielded?

• A. Ethernet (Cat 5e)
• B. Ethernet (Cat 6)
• C. Ethernet (Cat 5)
• D. Ethernet (Cat 7)

Answer: (A)

The speed and bandwidth combination described points to Category 6. Cat6 cables are designed to carry up to 1 Gbps with a bandwidth of 250 MHz, which is higher than Cat5e’s 100 MHz ratings. The mention of shielded or unshielded reflects that Cat6 cables can be configured as either unshielded twisted pair (UTP) or shielded twisted pair (STP), offering flexibility to reduce interference at higher frequencies. Cat5 and Cat5e don’t reach the 250 MHz bandwidth, so they don’t meet the stated spec, and Cat7 targets much higher performance (often 10 Gbps and beyond) with even higher bandwidths.
