Question 31/132
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.
Correct Answer: B
Detailed Explanation: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.
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.
