Introduction To The Cisco IOS

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. The command show ip protocols will actually show you the broadcast address for each interface—too bad it isn't a possible answer. Your best answer is show interfaces - which will provide the IP address and mask for each interface. You can then determ
