Web Science/Part1: Foundations of the web/Internet Protocol/IP header/quiz

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.

4

What is DSCP used for?

	increase the service of internet service provider
	prioritize traffic
	increase the profit of internet service provider

5

Which of the following becomes possible due to the use of TTL

	reliability
	discarding falsely routed packages
	high transfer speed
	finding the shortest routes

6

Which of the IP header files will change while routing?
