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






2. 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.






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






4. What are the server requirements for storing a zone in AD?






5. Increasing the refresh interval ______ zone transfer traffic.

13. A ______ is a public key for a remote DNS server that is trusted and able to provide DNSSEC responses.






14. ______ zones provide a means to offload DNS query traffic in areas of the network where a zone is heavily queried and used.






15. The first step in preparing a zone for DNSSEC is to back up the current zone data. To back up a zone - type the following command at an elevated command prompt: _______.






16. Together - aging and scavenging provide a mechanism to ______ resource records - which can accumulate in zone data over time. Both aging and scavenging are disabled by default.






17. 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.






18. By right-clicking a secondary zone in the DNS Manager console tree - you can use the shortcut menu to perform the following secondary zone update operations:






19. TTL values are not relevant for resource records within their authoritative zones. Instead - the TTL refers to ______ in nonauthoritative servers. A DNS server that has cached a resource record from a previous query discards the record when that reco






20. 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
