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. 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.






2. 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.






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






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 ______ refers to the process of deleting outdated resource records on which time stamps have been placed.






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






6. 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.






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






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






9. 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.






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






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






13. 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.






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






15. The four options presented on the _____________________ are the following: 1. To All DNS Servers In This Forest 2. To All DNS Servers In This Domain 3. To All DCs In This Domain 4. To All DCs Specified In The Scope Of This Directory Partition






16. 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






17. 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






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






19. 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.






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






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






22. 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 ______.






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






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






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






26. Increasing the refresh interval ______ zone transfer traffic.






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






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






29. 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.






30. 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: _______.






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






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






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






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






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






36. 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:






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






38. 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.






39. To enlist other DNS servers in the partition - type the following command:






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






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






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