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. 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.






4. 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.






5. 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 ______.






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






7. 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:






8. 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






9. Manually created resource records for all zone types are assigned a time stamp of 0; this value indicates that they ______ be aged.






10. To enable aging for a particular zone - you have to enable this feature both at the ______ level.






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






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

16. ______ are public keys from other zones that are used to validate digitally signed records originating from those zones and from delegated subdomains that are also DNSSEC-compatible.






17. 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.






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






20. A secondary zone will not be recognized as a valid name server until it contains a valid copy of zone data. For the secondary zone to obtain this data - you must first ______ to that server.






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






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






23. A ______ is a data structure in AD that distinguishes data for different replication purposes.

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






26. ______ resource records are used to specify the location of specific services in a domain.






27. The GlobalNames zone is compatible only with DNS servers running ______. Therefore - it cannot replicate to servers running earlier versions of Windows Server.

29. A ______ is a database containing records that associate names with addresses for a defined portion of a DNS namespace.






30. The value you configure in the ______ text box determines how long a secondary DNS server waits before querying the master server for a zone renewal. The default value for this setting is 15 minutes.






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