Which type of Ethernet interfaces are supported by all NGFW models?

The selection of interfaces that includes 1Gbps, 100Mbps, and 10Mbps is supported by all next-generation firewall (NGFW) models, making it the suitable choice. These speeds correspond to common Ethernet standards used in networking, providing a versatile range that can accommodate various networking needs.

1Gbps interfaces are widely adopted in modern networks for their ability to handle significant amounts of data traffic efficiently. Meanwhile, 100Mbps and 10Mbps interfaces cater to legacy systems and less bandwidth-intensive applications, ensuring backward compatibility and connectivity with older network devices.

This combination covers essential network speeds to facilitate both high-performance data transmission and support for diverse deployment scenarios across different environments. The absence of SFP and SFP+ from the correct response is significant since these are specific types of physical interfaces that, depending on the model and configuration of the NGFW, may not be universally supported. Hence, the focus on the three specified speed categories provides a more accurate representation of what is universally available in NGFW models.
