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






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






3. 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 ______.






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






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






6. 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.






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

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






10. 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






11. 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.






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

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

18. The most common resource records you need to create manually include the following:






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






20. 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: _______.






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






22. 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.






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






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






25. 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






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.






27. 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.






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






29. 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.






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






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






32. 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






33. Increasing the refresh interval ______ zone transfer traffic.






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

36. 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.






37. 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.






38. To create a custom application directory partition - type the following command:
