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. The ______ partition is replicated among all DCs that are also DNS servers in every domain in an AD forest.






3. The ______ partition is replicated among all DCs that are also DNS servers in a particular domain






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






5. ______ in DNS refers to the process of using time stamps to track the age of dynamically registered resource records.






6. When the zone is stored in a file instead of AD - by default the primary zone file is named zone_name.dns - and this file is located in the ______ folder on the server.






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






8. A secondary zone will not be recognized as a valid name server until it contains a valid copy of zone data. For the secondary zone to obtain this data - you must first ______ to that server.






9. ______ 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.






10. When you create a new zone - two types of records required for the zone are automatically created: ______

12. DNSSEC enables a DNS server to ______ the resource records in its zones.

17. The Zone Transfers tab also allows you to configure ______ to secondary servers whenever a change occurs at the primary zone.






18. 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






19. 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.






20. 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.






21. Increasing the refresh interval ______ zone transfer traffic.






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

27. The GlobalNames zone is compatible only with DNS servers running ______. Therefore - it cannot replicate to servers running earlier versions of Windows Server.
