Which category supports 10 Gbps with a 600 MHz bandwidth and is described as shielded?

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

Answer: (A)

The key idea is that higher bandwidth (measured in MHz) plus shielding enables higher data rates like 10 Gbps by reducing interference and allowing signals to ride over a wider frequency range. The category described as shielded and specified around 600 MHz is Cat 7, which uses shielding (such as S/FTP) to cut down crosstalk and EMI and is marketed with a bandwidth near 600 MHz. That combination supports 10 Gbps over typical Ethernet distances. Other categories can reach 10 Gbps under certain conditions, but their standard bandwidths don’t match the 600 MHz figure as clearly, and not all are described as shielded to the same extent. So the description points to Cat 7.
