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. 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






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






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

5. 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.






6. What does the 10 refer to in the following example: _ldap._tcp SRV 0 0 389 dc1.lucernepublishing.com.SRV 10 0 389 dc2.lucernepublishing.com.

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






11. 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.






12. 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






13. 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.






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






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






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






17. 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.






18. 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.






19. 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.






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






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






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






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






24. 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.






25. 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






26. 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.






27. 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.






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






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






30. 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.






31. 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.






32. 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.

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






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






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