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.

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






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






5. 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.






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

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






27. 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

30. To configure notifications - click ______ on the Zone Transfers tab when zone transfers are enabled.






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

36. 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
