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. A ______ is a data structure in AD that distinguishes data for different replication purposes.






6. To ______ a zone is to create a new zone for a subdomain within a DNS namespace and relinquish authority of that new zone.






7. A ______ zone is similar to a secondary zone - but it contains only those resource records necessary to identify the authoritative DNS servers for the master zone.






8. When you do not store a zone in AD - the zone is called a ______ zone - and zone data is stored in text files on the DNS server.

10. You can perform a delegation only from a ________________.






11. Active Directory-integrated zones perform time stamping for dynamically registered records by default - even before aging and scavenging are enabled. However - primary standard zones place time stamps on dynamically registered records in the zone onl






12. Increasing the refresh interval ______ zone transfer traffic.






13. For a DC to fall within the scope of such a directory partition - you must ______ that DC in the partition.






14. To enable GlobalNames zone support - At an elevated command prompt - type the following: ______.

19. What is the name of the record that contains a hash of the public key in a delegated subdomain?






20. ______ zones provide a means to offload DNS query traffic in areas of the network where a zone is heavily queried and used.

22. The refresh interval is the time after the no-refresh interval during which time stamp refreshes are ______ and resource records are not scavenged. The default refresh interval is 7 days.






23. The most common resource records you need to create manually include the following:






24. DNSSEC in Win Server 2008 R2 allows a ______ to validate DNS data on behalf of its Win 7 clients.






25. 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.






26. You use Group Policy to configure DNS clients to _________________.






27. ______ are public keys from other zones that are used to validate digitally signed records originating from those zones and from delegated subdomains that are also DNSSEC-compatible.






28. Scavenging can occur only when ______ is enabled.






29. 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.






30. 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.






31. Consequently - when aging is enabled - dynamically registered resource records can be scavenged after ___ days by default.






32. This operation performs a zone transfer from the secondary zone's master server regardless of the serial number in the secondary zone's SOA resource record.






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






34. What are the server requirements for storing a zone in AD?
