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.

26. Which of following VLAN frame encapsulation types are configurable on a Cisco switch?






27. The system LED is amber on a new Certkiller Catalyst 2950 series switch. What does this indicate?






28. The CK network administrator needs to determine what LAN devices to install on the CK network. What are two advantages of using Layer 2 Ethernet switches over hubs?






29. The Certkiller network administrator issues the ping 192.168.2.5 command and successfully tests connectivity to a host that has been newly connected to the network. Which protocols were used during the test?






30. The Certkiller network administrator wants to use a router named CK1 to segment the local network. What are some of the advantages of using CK1 to segment the network? (Choose two)






31. Which of the following devices can the Certkiller network administrator use to segment the LAN?
