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.

12. In this way - digital signatures use ______ cryptography to prove that information is unspoofed and unchanged.

15. To create a custom application directory partition - type the following command:

17. When you create a new zone - two types of records required for the zone are automatically created. List them.






18. 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.






19. 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






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






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






22. 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.

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.

30. 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.
