An administrator connects two switches together in a local enterprise network. The ports of one switch support Fast Ethernet, while the ports of the other switch support Gigabit Ethernet. Hosts connected to one switch are able to communicate, however communication between the two switches fails.
What is the possible reason for this?
A Fast Ethernet port operates at 100 Mbps, while a Gigabit Ethernet port operates at 1000 Mbps. These two ports require proper support and configurations to communicate with each other. If one switch's ports are Fast Ethernet and the other switch's ports are Gigabit Ethernet without proper negotiation mechanisms or settings, communication between them might fail. Therefore, the most plausible reason for the communication failure is that a Fast Ethernet port cannot directly communicate with a Gigabit Ethernet port without additional configuration or support.
The answer should be C
Not true, as I know the Huawei exam speaks about general constellations, L2 and L3 devices aren't always in auto negotation mode, if we speak of multivendor solutions.
