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. You can perform a delegation only from a ________________.






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






3. ______ 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.






4. 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.






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






6. 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 ______.






7. 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:






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






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






10. 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 ______.






11. 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.






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






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






14. 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.






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






16. 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






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






18. 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: _______.






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






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






21. 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






22. 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.






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






24. Increasing the refresh interval ______ zone transfer traffic.






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






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






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






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






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






30. 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.






31. 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






32. 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.






33. 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






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






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






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






37. 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.






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






39. The ______ service uses SRV records to locate DCs in a domain by searching the domain for the LDAP service.






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






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






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






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






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

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






47. Scavenging can occur only when ______ is enabled.






48. 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.
