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.

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






12. 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

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 ______ refers to the process of deleting outdated resource records on which time stamps have been placed.






31. Alias resource records are sometimes called canonical names (CNAME). These records allow you to ______ a single host.






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






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

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






39. This operation reloads the secondary zone from the local storage.






40. Also recommended for use in the following scenarios: When a host specified in an A resource record in the same zone needs to be renamed - When a generic name for a well-known server such as www needs to resolve to a group of individual computers tha






41. Win 7 clients can be configured to request DNSSEC through the Name Resolution Policy Table (NRPT) in ______.
