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






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






4. Increasing the refresh interval ______ zone transfer traffic.






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






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






7. 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.






8. 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.






9. 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.






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






11. 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






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






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






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






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






16. 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.






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






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






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






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






21. 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

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






25. 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






26. 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.






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 ______ refers to the process of deleting outdated resource records on which time stamps have been placed.






28. 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.






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






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






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






32. 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.






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






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






35. 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.
