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. 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






2. 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:






3. 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.






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






5. 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






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






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






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






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






10. 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.






11. 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.






12. 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.






13. 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.






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






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






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






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






18. 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.






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






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






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






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






23. 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 ______.






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






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






26. 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.






27. 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






28. Scavenging can occur only when ______ is enabled.






29. 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.






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






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






32. 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.






33. 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.






34. 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.






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






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






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






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






39. 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: _______.






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






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






42. 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 ______.






43. 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






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






45. 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
