Use the console buttons to scroll through the 75 questions.

This interface has been designed as a reality check and not as a study tool. Focus on the content within the CCNA 607 Questions along with the 607 Reviews menu options prior to answering the questions here.

FYI: There are approximately 60 questions on the actual exam including two labs. All must be completed within 90 minutes. If you can answer 85% of these questions correctly within 50 to 60 minutes -- that will leave 30 to 40 minutes to complete the 2 Labs.
