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. A ______ zone provides original read-write source data that allows the local DNS server to answer DNS queries authoritatively about a portion of a DNS namespace.






2. Manually created resource records for all zone types are assigned a time stamp of 0; this value indicates that they ______ be aged.
