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.

2. 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.






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






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 ______ refers to the process of deleting outdated resource records on which time stamps have been placed.






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






6. 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.






7. 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






8. 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






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






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






11. 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:






12. 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.






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






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

16. 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.






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. Scavenging can occur only when ______ is enabled.






19. 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






20. 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.






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






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






23. 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.






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






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






26. 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.

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






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






30. 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.






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






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






33. The no-refresh interval is the period after a time stamp during which a zone or server rejects a ______ refresh. The default no-refresh interval is 7 days.






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






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






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






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






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