Which Ethernet frame composition provides the minimum size requirement for a valid frame?

The correct response centers on the Ethernet frame structure, which mandates specific minimum sizes for valid frames. An Ethernet frame consists of a header, a payload (data), and a trailer (which includes the Frame Check Sequence for error checking).

The minimum payload size for an Ethernet frame is 46 bytes. This requirement ensures that the total frame size reaches a minimum of 64 bytes when including the standard header (14 bytes) and trailer (4 bytes). Therefore, for the frame to be considered valid, it must contain at least the header (14 bytes), the minimum payload (46 bytes), and the trailer (4 bytes).

This configuration meets the essential requirement of 64 bytes, making it the minimum composition necessary for an Ethernet frame to be valid. The other options do not align with this structure or size requirement, either by mistakenly including incorrect combinations of components or failing to meet the minimum size criteria.
