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. 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.






2. 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:






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






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

6. 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.






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






8. 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






9. This operation performs a zone transfer from the secondary zone's master server regardless of the serial number in the secondary zone's SOA resource record.






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






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






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






13. 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 ______.






14. For a delegation to be implemented - the parent zone must contain a _____ and an _____ (called a glue record) pointing to each authoritative server of the delegated domain.






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






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






17. When the zone is stored in a file instead of AD - by default the primary zone file is named zone_name.dns - and this file is located in the ______ folder on the server.






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






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






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






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






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






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






24. 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.






25. 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.






26. A ______ zone provides original read-write source data that allows the local DNS server to answer DNS queries authoritatively about a portion of a DNS namespace.






27. 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.






28. 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.






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






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






31. To ______ a zone is to create a new zone for a subdomain within a DNS namespace and relinquish authority of that new zone.

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






35. 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.






36. 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






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

46. 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
