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.

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






3. 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

5. 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.






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






7. ______ refers to the process of deleting outdated resource records on which time stamps have been placed.






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

11. 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.






12. ______ 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.






13. 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.






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






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






16. Used to facilitate the resolution of single-label computer names in a large network.






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






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






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






20. The ______ allows you to specify the DNS query suffixes - prefixes - FQDNs - or reverse lookup subnets for which a Win 7 or Win Server 2008 R2 client will request DNSSEC.






21. 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.






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






23. Scavenging can occur only when ______ is enabled.






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






25. Alias resource records are sometimes called canonical names (CNAME). These records allow you to ______ a single host.






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






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






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






29. 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:






30. 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.






31. 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: _______.






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






33. 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.






34. 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.






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






36. 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.






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






38. 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.






39. When scavenging is not enabled - you can perform manual scavenging in zones by right-clicking the server icon in the DNS Manager console tree and then choosing ______.






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






41. 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.






42. Increasing the refresh interval ______ zone transfer traffic.






43. 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
