  • Physical (“correct” answer)
  • Transport
  • Internet
  • Link

I was thinking it was maybe just me, but this question didn’t make sense to me as worded. And as the percentage correct is currently 23%, I’m thinking it’s not just me.

I don’t usually tag the “correct” answer in these discussions, but I got it wrong, and thought it might provide some context.

I think they may been trying to differentiate between TCP/IP model and OSI model, but their choice of words just makes it more confusing.

Very poorly worded question. A better question would have been:

Which is not a layer of the TCP/IP model?

Even then the choices Physical and Link are incorrect.

Here is a good graphic mapping both models:

Very poorly written. Are they talking about the TCP/IP or OSI model? It’s not an application layer, that confuses things with the application layer of the OSI model. TCP/IP occupies 2 layer there, Network for IP and Transport for TCP. On the TCP model it occupies Internet for IP and Transport for TCP. Since they mentioned Internet, then they are talking about the TCP/IP Model.

That then leaves you with 2 choices, physical and link.

Link is not a layer of either model unless you are going to say it’s the Data Link layer of the OSI model.

To me both Link and Physical would both be correct answers regardless if Link is referring to Data Link or not…

If they were talking about the OSI model, Internet is not a named layer.

That is an excellent graphic.

Based on that illustration, the question could also be worded as, "what is not a protocol within the TCP/IP *Model’*s Application Layer?

I got this one (wrong) yesterday, i was half asleep so had just assumed it way my foggy brain getting confused. Reassuring others are thinking it’s wonky too.

Actually that question should probably be nuked, if you look at the mapping between the OSI and TCP Models, none of those map.

Sorry it took so long for me to take a look. I just made it inactive because I agree, it appeared too vague and confusing, possibly getting too far into the minutiae. Josh, any salvaging this, in your opinion?
