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






2. The refresh interval is the time after the no-refresh interval during which time stamp refreshes are ______ and resource records are not scavenged. The default refresh interval is 7 days.






3. 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: _______.






4. ______ in DNS refers to the process of using time stamps to track the age of dynamically registered resource records.






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






6. By default - zone transfers are ______ from any zone.






7. The value you configure in the ______ text box determines how long a secondary server waits before retrying a failed zone transfer. Normally - this time is less than the refresh interval. The default value is 10 minutes.






8. Win 7 clients can be configured to request DNSSEC through the Name Resolution Policy Table (NRPT) in ______.






9. DNS delegations are automatically used to separate ______ in a single forest.






10. The ______ option stores the zone in the user-created application directory partition specified in the associated drop-down list box.






11. 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.






12. To enable GlobalNames zone support - At an elevated command prompt - type the following: ______.






13. By default - DCs include two application directory partitions reserved for DNS data: ______.






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






15. What does the 10 refer to in the following example: _ldap._tcp SRV 0 0 389 dc1.lucernepublishing.com.SRV 10 0 389 dc2.lucernepublishing.com.






16. For a DC to fall within the scope of such a directory partition - you must ______ that DC in the partition.






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






18. The ___________________ dialog box enables you to modify two key settings related to aging and scavenging: 1. the no-refresh interval 2. and the refresh interval






19. The Zone Transfers tab also allows you to configure ______ to secondary servers whenever a change occurs at the primary zone.






20. To add an NS record - double-click any existing NS record in DNS Manager and add the server data to the ______ tab.






21. The ______ option stores the new zone in the ForestDnsZones partition. Every DC in the entire forest and on which the DNS Server role is installed will receive a copy of the zone.






22. 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






23. A ______ zone is similar to a secondary zone - but it contains only those resource records necessary to identify the authoritative DNS servers for the master zone.






24. 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.






25. 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.






26. DNSSEC enables a DNS server to ______ the resource records in its zones.






27. When you create a new zone - two types of records required for the zone are automatically created: ______

29. The no-refresh interval is the period after a time stamp during which a zone or server rejects a ______ refresh. The default no-refresh interval is 7 days.






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.






31. The most common resource records you need to create manually include the following:






32. 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
