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.

2. ______ resource records are used to specify the location of specific services in a domain.






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






4. 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.






5. 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.






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






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






8. Increasing the refresh interval ______ zone transfer traffic.






9. To add an NS record - double-click any existing NS record in DNS Manager and add the server data to the ______ tab.






10. 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.
