Test your basic knowledge |

Subjects : cisco, it-skills, ccna
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.
1. Which of the following statements correctly describe the differences between half-duplex and full-duplex Ethernet?






2. While troubleshooting an issue in the Certkiller LAN you notice that a network interface port has collision detection and carrier sensing enabled on a shared twisted pair network. From this statement - What is known about the network interface port?






3. Which OSI layer is associated with the following: The acknowledgment of transmissions - sequencing - and flow control across a network?
