If the value of the 'Type/Length' field of an Ethernet data frame is 0x0800, the length range of the upper-layer packet header carried by the data frame is from 20B to 60B.

A.

TRUE

Answers
A.

TRUE

B.

FALSE

Answers
B.

FALSE

Suggested answer: B

Explanation:

Detailed

The Type/Length field value of 0x0800 indicates that the upper-layer protocol is IPv4. However, the length of the IPv4 header can range from 20 to 60 bytes, not the length of the entire upper-layer packet. The field refers to the type of the encapsulated protocol, and the length is not constrained to the header alone.
