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.

18. Any of three events can ________________: When the refresh interval of the primary zone's SOA resource record expires - When a server hosting a secondary zone boots up - When a change occurs in the configuration of the primary zone and this primary

27. 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.






28. If either of the default application directory partitions is deleted or damaged - you can re-create them in DNS Manager by right-clicking the server node and choosing ______.






29. Public key cryptography provides ______ - which means that separate keys are used to encrypt and decrypt data.






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






31. What kind of zones do not automatically perform time stamping on dynamically created resource records?






32. The value you configure in the ______ text box determines the default Time to Live (TTL) that is applied to all resource records in the zone. The default value is one hour.






33. The ______ option stores the new zone in the Domain-DnsZones partition. Every DC in the local domain and on which the DNS Server role is installed will receive a copy of the zone.

39. To enlist other DNS servers in the partition - type the following command:






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 ______ refers to the process of deleting outdated resource records on which time stamps have been placed.
