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.

20. The ______ option stores the new zone in the Domain-DnsZones partition. Every DC in the local domain and on which the DNS Server role is installed will receive a copy of the zone.






21. The source zones from which secondary zones acquire their info are called ______ - and the data copy procedures through which this info is regularly updated are called zone transfers.






22. A ______ is a public key for a remote DNS server that is trusted and able to provide DNSSEC responses.

30. 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.






31. Increasing the refresh interval ______ zone transfer traffic.






32. The value you configure in the ______ text box determines the length of time that a secondary server - without any contact with its master server - continues to answer queries from DNS clients. After this time elapses - the data is considered unrelia
