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.

Which command will delete the contents of NVRAM on a router?
Bandwidth
Router#access-enable

29. The command service password-encryption - from global configuration mode - will encrypt the passwords.
