Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

11. Which layer is used for reliable communication between end nodes over the network and provides mechanisms for establishing - maintaining - and terminating virtual circuits; transport-fault detection recovery; and controlling the flow of information?






12. Ethernet is defined at these layers.






13. Which layer chooses and determines the availability of communicating partners along with the resources necessary to make the connection - coordinates partnering applications - and forms a consensus on procedures for controlling data integrity and err






14. Segmentation of a data stream happens at which layer of the OSI model?






15. Which layer is responsible for keeping the data from different applications separate on the network?
