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.

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






27. The _____ option stores the zone in the domain partition. Every DC in the local domain will receive a copy of the zone - regardless of whether the DNS Server role is installed on that DC.

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






38. 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
