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. 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.






2. 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.






3. 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: _______.






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






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






6. What is the name of the record that contains a hash of the public key in a delegated subdomain?






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






8. 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






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






10. 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.






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






12. 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.






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






14. ______ 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.






15. 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.






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






17. 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.






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






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






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






21. 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.






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






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






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






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






26. Scavenging can occur only when ______ is enabled.






27. 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






28. 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.






29. 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






30. 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.






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






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






33. 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.






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






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






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






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






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






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






40. To enlist other DNS servers in the partition - type the following command:






41. 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.






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






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






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






45. Increasing the refresh interval ______ zone transfer traffic.






46. 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.






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






48. 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:






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






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