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. 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: _______.






2. 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.






3. Also recommended for use in the following scenarios: When a host specified in an A resource record in the same zone needs to be renamed - When a generic name for a well-known server such as www needs to resolve to a group of individual computers tha






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






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






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






7. 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






8. 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.






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






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






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






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






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






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






15. 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.






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






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 ______ refers to the process of deleting outdated resource records on which time stamps have been placed.






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






19. 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.






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






21. 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.






22. 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.






23. 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.






24. 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 ______.






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






26. The ______ partition is replicated among all DCs that are also DNS servers in a particular domain






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






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






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






30. 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.






31. 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






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






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. You can perform a delegation only from a ________________.






35. 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






36. 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.






37. Increasing the refresh interval ______ zone transfer traffic.






38. Scavenging can occur only when ______ is enabled.






39. 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:






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






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






42. When you create a new zone - two types of records required for the zone are automatically created. List them.






43. 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.






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






45. 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 ______.






46. 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.






47. 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.






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






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