This is a match the letters to the numbers task involving the OSI Reference Model. The OSI Model is a "must" to know for the Network+ exam so you really need to know it forwards and backwards. Match the OSI layer names represented by the letters with the protocols & services represented by the numbers. More than one number may apply to a letter. Good luck. Answers later:

A. Application
B. Presentation
C. Session
D. Transport
E. Network
F. Data Link
G. Physical

1. TIFF
2. 802.3
3. SPX
4. UDP
5. RIP
6. SCP
7. ASCII
8. LLC
9. SQL
10. NCP
11. Token Ring
12. BootP

I'm going to have a bash, hopefully get some right here, big
trouble if i'm way wrong, I doing my exam shortly.....lol

A. Application 10
B. Presentation 10
C. Session 9
D. Transport 4+5+3
E. Network 5
F. Data Link 11+8
G. Physical 2+11

Wow, time to rack the brain lol

used to know everything to do with OSI off by heart, but the knowledge had slipped lol

ok, here goes.


A. Application 10 12
B. Presentation 1 7
C. Session 6 9
D. Transport 3 4
E. Network 5
F. Data Link 8
G. Physical 2 11


Think I've got it all lol.

 

This one wasn't easy (as evidenced by the lack of responses). Kudos to those who did answer. Correct answers as follows:

A. Application: 10
B. Presentation: 1, 7
C. Session: 6, 9
D. Transport: 3, 4
E. Network: 5, 12
F. Data Link: 8
G. Physical: 2, 11

See you next time.

 

Ok, im gonna risk embarrasment here and post my confusion
fair enough it has been a while since i activley studied the OSI model, but I like to think my concepts are still ok

I was sure that Ethernet (802.3) and Token Ring (802.5) are at the Data link layer and NOT the physical layer, numerous reasons help to define this, firstly, the term MAC and Ethernet address are interchangable (MAC being a sub layer of the Datalink layer), secondly, Ethernet uses FRAMES, the encapsulated name of data at the data link layer (physical is 'bits'), thirdly the diverse media ethernet can be run over, leading it to be media independant, what the OSI was indended for

Examples of Physical layer items would be
UTP, STP, Serial Cables, Fiber et all, as far as I am aware :/

Please feel free to correct me if i got a wire crossed, or woke up on the dumb side of the bed this morning

 

I stand corrected Phoenix. You are correct. Here's the source:

My apologizes.

 

Lol trip, no apologies needed mate, was just trying to work out if I had gone mad or not!

 

Quite pleased with myself on that one really, need to brush up
a bit more though.
