MCTS: Configuring A DNS Zone Infrastructure

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.

5. During this operation - the server hosting the local secondary zone determines whether the serial number in the secondary zone's SOA resource record has expired and then pulls a zone transfer from the master server.






6. The no-refresh interval is the period after a time stamp during which a zone or server rejects a ______ refresh. The default no-refresh interval is 7 days.






7. Increasing the refresh interval ______ zone transfer traffic.






8. ______ refers to the process of deleting outdated resource records on which time stamps have been placed.
