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






2. 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.






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






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






5. 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






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






7. 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.






8. You must be a member of the ______ group to create an application directory partition.






9. 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 ______.






10. 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.






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






12. 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.






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






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






15. Scavenging can occur only when ______ is enabled.






16. 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.






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






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






19. 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.






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. 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.






22. You can perform a delegation only from a ________________.






23. 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.






24. Increasing the refresh interval ______ zone transfer traffic.






25. 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






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






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






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






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






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






31. 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.






32. The ______ option stores the new zone in the Domain-DnsZones partition. Every DC in the local domain and on which the DNS Server role is installed will receive a copy of the zone.






33. You use Group Policy to configure DNS clients to _________________.






34. DNSSEC in Win Server 2008 R2 allows a ______ to validate DNS data on behalf of its Win 7 clients.






35. 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.






36. 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






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






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






39. 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: _______.






40. ______ 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.






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






42. 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.






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






44. 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






45. 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

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






48. 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.
