Question

The simple answer is that they are bigger-than-normal Ethernet frames. If that doesn’t mean anything to you, a normal Ethernet frame (layer 2) has 42-1500 bytes of payload. On top of that is about 22 bytes of overhead, which means 1.4 to up to 34 percent of the frame is overhead only. By definition, a jumbo frame has more than 1500 bytes of payload. Because of that, there is some flux in how large that frame is, but 1600-9000 bytes of payload is typical. The overhead (still 22 bytes) is between 0.2 and 1.3 percent and is significantly less. Past that, there is a super jumbo frame, which – you guessed it – is over 9000 bytes (generally up to 64000 bytes)

The overhead for a jumbo frame is _____.

a 22 bytes no matter how large the payload

b about 30% of the average network payload

c dependent on the size of the payload

d dependent on the amount of NIC offloading

Explanation / Answer

Answer - Option (a)

The overhead which is the Ethernet header is of size 22 bytes and its size does not vary if the Ethernet frame is of normal size (up to 1500 bytes) or Jumbo size (up to 9000) or super Jumbo size (up to 64000 bytes)
