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






2. Increasing the refresh interval ______ zone transfer traffic.






3. 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.






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






5. 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.






6. 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.






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






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. 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






10. 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.






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






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






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






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






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






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






17. 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






18. 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.






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






20. What is the name of the record that contains a hash of the public key in a delegated subdomain?






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






22. 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.






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






24. 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.






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






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






28. 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.






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






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






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






32. The value you configure in the ______ text box determines how long a secondary DNS server waits before querying the master server for a zone renewal. The default value for this setting is 15 minutes.

34. The ___________________ dialog box enables you to modify two key settings related to aging and scavenging: 1. the no-refresh interval 2. and the refresh interval






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






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






37. 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.






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

42. 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.
