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






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






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






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






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






6. 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






7. ______ 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.






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






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






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






11. 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.






12. 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.






13. 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: _______.






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






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






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






17. 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






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






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 ______ refers to the process of deleting outdated resource records on which time stamps have been placed.






20. The refresh interval is the time after the no-refresh interval during which time stamp refreshes are ______ and resource records are not scavenged. The default refresh interval is 7 days.






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






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






23. 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.






24. 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.






25. Scavenging can occur only when ______ is enabled.






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






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






28. 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.






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






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






31. 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.






32. 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.






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






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






35. 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.






36. 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.






37. 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.






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






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






41. 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






42. 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






43. 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






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






45. 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.






46. Increasing the refresh interval ______ zone transfer traffic.






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






48. 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.






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






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