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






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






3. Scavenging can occur only when ______ is enabled.






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






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






6. A ______ is a public key for a remote DNS server that is trusted and able to provide DNSSEC responses.






7. 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.






8. 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 ______.






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






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






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






12. 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.






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






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






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






16. 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.






17. 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.






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






19. 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.






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






21. 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.






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






23. 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: _______.






24. ______ 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.






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






26. 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.






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






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






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






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






31. 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.






32. 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






33. 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:






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






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






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






37. 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.






38. There are three basic steps in _______________: 1. Enable GlobalNames zone support. 2. Create the GlobalNames zone. 3. Populate the GlobalNames zone.






39. Increasing the refresh interval ______ zone transfer traffic.






40. 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






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






42. 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






43. 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.






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






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






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






47. 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.






48. 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.
