Da Wikiversità, l'apprendimento libero.

1 You are using ethernet II with etherType 0x0800 with a maximum data payload to store a standard IPv4 package with IHL=5. How much data can you put inside one ethernet frame

As much as I want
65536 Bytes
1518 Bytes
1500 Bytes
1480 Bytes

2 An IP package has Bit number 49 set to 1 and has a data payload of 2000 Bytes. It now arrives at an Ethernet Network. What will happen?

The package is fragmented into two packages which both fit into the Ethernet frames of the network
An error message will be send to the sender (specifying the maximum allowed data size)
This will never happen since Bit 49 was set to 1.
