Need some TCP/IP Questions and Answers

I am putting together a simple TCP/IP test for work colleagues to gauge their understanding on the concepts.

If anyone can think of any interesting question (and answers, if you want ) for it then please post them here. I have thrown together around 40. (Didn't get around to adding any DNS related stuff so anything around that would also be useful)

Cheers in advance

Urrr..
Depends on how mean you want to be to them and exactly what you're trying to find out. You might want to consider some of these:
1) 3-way TCP handshake
2) What class is this address in?
3) TTL (maybe as a scenario question)
4) 'Internal' protocols (ICMP, ARP, DHCP)
5) Simple address/subnet mask questions
6) Routing
7) Private IP addresses
NAT
9) MSS/MTU
10) Sequence numbers and/or windowing
11) Differences between TCP and UDP

BONUS QUESTION:
What's the 8th layer of the OSI Model?
Answer: Politics

I always thought it was the finance department

Haha, nice!

OK ok.....back to the real questions:

1) Order of OSI and TCP/IP model
2) What are the different layers of the OSI and TCP/IP models
3) Common port numbers
4) Acronym that is used to describe the DHCP IP registration process (DORA)
5) Difference between DNS and WINS
6) different between HOSTS and LMHOSTS

Brief description of header fields?

Describe what happens to a packet as it passes down the stack of a host onto the wire and back up the stack on another host.

Describe that same process from wire to a different network (via Layer three routing.)

There are so many I come across during troubleshooting with wireshark, fire it up do some captures, try to describe what went on, you'll come up with questions

Goog Luck, maybe you can post your final test questions here, I'd like to see them.
